What disk should I buy for my mobile hard disk?

What kind of mobile hard disk is good?

Question 1: I want to buy a good mobile hard disk. What kind is good? Recommended model: (Because USB3.0 is much faster than USB2.0, I don't recommend 2.0! )

Give you some advice: [Note: The above recommended models are all original mobile hard disks of domestic brands, which will not be discussed here]

[Note: Hitachi changed its name to HGST due to the acquisition. All recommended models are USB3.0]

1TB or above, it is recommended to assemble the large-capacity desktop hard disk with mobile hard disk box.

Mobile hard disk box shopping: For better mobile hard disk box, you can see Wang Biao or Yuangu (with encryption).

If you want to assemble a 2.5-inch mobile hard disk, the operation scheme is the same as above! It's just a hard disk box, 2.5 inches.

It is recommended to buy Hitachi Western Digital for notebook hard disk, and Seagate and other brands are highly recommended.

Because at present Seagate's home desktop hard disk, notebook hard disk and mobile hard disk have many problems!

Don't move and vibrate violently when using the mobile hard disk, and avoid bumping!

Because of the violent vibration, it will be scrapped, remember! Be sure to use secure deletion, and then remove the hard disk!

Don't unplug the data cable forcibly when transmitting data, it will cause serious physical failure!

Again, don't buy Seagate There are too many questions! ! It's really hard to buy too many fake Samsung products!

Toshiba Fujitsu's hard disk is prone to problems in items C4 and C7 of hard disk S.M.A.R.T

So Seagate Samsung ......

Question 2: What kind of mobile hard disk is of good quality? Main technical indicators of mobile hard disk:

1 interface type

There are three external interfaces in mobile hard disk box: parallel port, IEEE 1394 and USB.

Mobile hard disk box, a parallel interface, appeared earlier because of its low data transmission rate and no plug-and-play function.

IEEE 1394, also known as Friewire, was put forward by Apple in the mid-1980s and is the standard interface of Apple computers. Its data transmission speed can theoretically reach 400Mbps, which supports hot dialing. However, only some high-end PC motherboards are equipped with IEEE 1394 interface, so its popularity is poor. Recommended to friends with special needs.

Mobile hard disk box of USB interface is the mainstream interface, which supports hot plug. There are two USB standards, USB 1. And the transmission speed of USB 2.0. USB 2.0 is as high as 480Mbps, which is 40 times that of USB 1. 1 interface. USB2.0 needs the support of the motherboard, but it is backward compatible. Mobile hard disk box of the same brand USB2.0 is 30 ~ 50 yuan more expensive than USB 1. 1. However, considering the huge speed difference and the fact that USB2.0 has become the mainstream of the market, it is recommended to buy a mobile hard disk box that supports USB2.0. Even if your current motherboard does not support it, you can prepare for future upgrades.

The size of mobile hard disk box.

Mobile hard disk box is divided into 2.5 inches and 3.5 inches. The 2.5-inch mobile hard disk box uses a laptop hard disk, and the 2.5-inch mobile hard disk box is compact and portable, and generally has no external power supply.

The 3.5-inch hard disk box uses a desktop computer hard disk, which is huge and relatively poor in portability. The 3.5-inch hard disk box usually comes with an external power supply and a cooling fan, and the price is relatively high.

In addition, there is a 5.25-inch mobile hard disk box, which can hold both a desktop hard disk and an optical drive to form an external hard disk, but its size is really difficult to be related to portability. It is recommended to buy a 2.5-inch mobile hard disk box that meets the portability requirements.

3 power supply

When the 2.5-inch USB mobile hard disk works, the hard disk and data interface are powered by the computer USB interface. USB interface can provide 0.5A current, while the working current of notebook computer hard disk is 0.7 ~ 1A, so general data copying will not be a problem. However, if the hard disk capacity is large or the mobile files are large, it is easy to have insufficient power supply, and if the USB interface supplies power to multiple USB devices at the same time, it is easy to have insufficient power supply, resulting in data loss or even hard disk damage. In order to strengthen the power supply, the 2.5-inch USB hard disk box will generally provide a power cord to obtain power from the PS/2 interface. Therefore, it is necessary to connect the PS/2 power cord when moving large files (it should be noted that the PS/2 interface does not support plug and play).

3.5-inch hard disk boxes generally have their own external power supply, and the power supply is basically no problem. The IEEE 1394 interface can provide the maximum current of 1.5A, so there is no need for an external power supply.

4. Materials, heat dissipation and shockproof of the mobile hard disk box.

Five major brands and market division

The mobile hard disk box market is clearly divided into different grades of products, with prices ranging from less than 40 yuan to more than 200 yuan. The cost of mobile hard disk box is mainly on the chip. At present, ISD300 chip of In-System company and ALiM562 1 chip of Ali company are generally used for high-end products in mobile hard disk box with USB2.0 interface, while GL8 1 1 chip of GenesysLogic company is mainly used for some low-cost products. High-end products have stable performance and good compatibility, and some products also have very practical functions such as USBHUB. Mobile hard disk box brands with good quality in the market include Newman, Mobile Star, Patriot, Bestler and Tsinghua Tongfang.

Question 3: What brand of mobile hard disk is of good quality? First, there is never such a thing as "the best". In terms of capacity, it is generally unnecessary to select 120G for 80G, and 7200 rpm for 5400 rpm. Remember that what suits you is the "best".

Second, from the brand point of view, each has its own advantages. Now evaluate the advantages and disadvantages of several common brands on the market.

1, Hitachi. Hitachi, the leader of the 2.5-inch hard disk market, bought IBM technology, so the notebook hard disk you see now is exactly the same as the previous IBM hard disk. Hard disk has become a major feature of IBM: durable and average performance. Advantages: good compatibility and durability. Disadvantages: high noise, high calorific value and average performance.

2, Samsung. Samsung's current market share should not be underestimated. In particular, the unique super-crystalline magnetic powder and encryption technology of Jinbao series have been threatening Seagate, another powerful competitor. Advantages: low noise, the cheapest price among similar products. Disadvantages: the power consumption is too high. At present, the power consumption of Samsung's hard disk is 5V0.85A, which is nearly double that of Seagate's 5V0.487A It is recommended to install it in a notebook computer, and it is not suitable as a mobile hard disk, because the maximum output of USB interface is 5V0.5A, and continuous load operation will cause data loss.

3. Seagate Seagate's large hard drives account for 70% of the desktop hard drive market. Due to poor marketing of notebook hard disk, it ranks second after Hitachi at present. Seagate's R&D strength is the strongest of its kind, and many of the same industries have used Seagate's patented technologies, such as vertical reading and writing technology and free-falling head suspension technology. Advantages: the strongest performance and leading technology. For example, the same 5400 rpm hard disk, Seagate has the lowest power consumption and the fastest speed. Disadvantages: the tray is exquisite, not resistant to falling, and requires high stability of power supply.

4. Western data. The brand was originally specialized in military industry, and later turned to the civilian market. The market share of 2.5-inch hard disk is not high, which may be due to poor marketing and low consumer recognition. Good quality, high safety factor, low in repair rate. Advantages: Super stability, 0.55A low power consumption and good noise control. Disadvantages: the disk body of Western Digital is made of special plastic. If it is BT 24-hour download, forget it. Simply put, it is suitable for mobile hard disk, not for notebook.

5, Toshiba, Fujitsu. Why do you want to introduce this brand together? There is a simple reason. Very rare in the market, mainly in notebook computers. Simply put, the power consumption is 0.6A, the performance is average, the noise is average, the calorific value is average, and the disk reading error rate is average. But because so many are average, the failure rate of this kind of hard disk is very low compared with that of repair rate, so notebook computer manufacturers especially like to use these two brands, not to mention Toshiba and Fujitsu are also experts in notebook computers. At present, big manufacturers such as Hewlett-Packard use Fujitsu hard drives, which reduces the cost because of the low repair rate, hehe.

Third, it's time to talk about hard disk boxes. Friends with a little computer knowledge should know. The so-called mobile hard disk is actually composed of an ordinary notebook hard disk and a shell with a control chip. This is true regardless of the original assembly. It's different whether it's original or assembled. Saving a machine with good accessories is more expensive than assembling a computer. In fact, this principle also applies to mobile hard disks. As for the quality, as long as you use genuine products, the quality is absolutely the same as the original ones.

Having said that, it can be summarized in one sentence: there is no best, only the one that suits you best.

Question 4: Which brand of mobile hard disk is better? 2.5-inch mobile hard disk (500GB) cost-effective choice:

Western Digital (WD)ElementsPortable Series 2.5-inch mobile hard disk 500GB479.00 Yuan.

Seagate) Raptor2.5-inch mobile hard disk 500GB (black) (ST905004EXM101-rk)

499 yuan

The above two items are licensed prices with invoices in Chinese mainland. You can go to the computer city to find these two things. As long as the price does not exceed this price, there will be no loss. Note: Be sure to invoice and write down the model clearly, otherwise you will not be able to enjoy the free warranty. In addition, the above two models are original mobile hard disks produced by hard disk manufacturers. Don't be fooled by js!

They are all u*** interfaces, and the mobile hard disks of 1tb are basically 3.5 inches, which are big and heavy and unnecessary.

Question 5: What brand of mobile hard disk should I choose? Generally there are three points:

1. Not made in China. When you can only buy domestic products, you can only buy Lang Ke and Lenovo. Other domestic brands? That's gambling. The price gap between foreign brands and domestic brands will not be too big. I would rather add money to buy big brands than be greedy for petty gains.

2. Don't use a 3.5-inch disk. The so-called desktop mobile hard disk can't be moved at all, and it can't be moved without external power supply. Move a wool. Still 2.5 inches is reliable, please fix it directly.

3. Don't make a whole dish. The integrated disk is a typical pit. Normal mobile hard disks are standard disks and conversion modules, and integrated disks are the integration of conversion modules on disks.

Generally, more than 90% of disk failures are contributed by conversion modules, and it goes without saying that there are many integrated disk pits.

In appearance, the low-end disks of Toshiba in the Big Three are all integrated disks as long as they tend to be square. Only Seagate is serious.

Question 6: What brand of mobile hard disk is better? Mechanical hard disks and mobile hard disks under 500G have no cost performance, and 1TB has the highest cost performance, with a price of more than 400 yuan. Western Digital and Seagate, both Toshiba and Samsung brands, have always made hard disks with high quality and after-sales maintenance, and the size is of course 2.5 inches, which is the most convenient! In addition, if you really don't need so much storage space, the size below 500G can fully meet your needs. You can also consider a smaller size, that is, 1.8 inch mobile hard disk, but neither Seagate nor Western Digital will make mobile hard disks of this size. You can choose Newman brand which has been studied for a long time in the field of 1.8 inch mobile hard disk, such as: 60GB Newman Minicard Jiyun 1.8 inch mobile hard disk.

Question 7: What brand of mobile hard disk is good? Aite data recovery answers for you: There are not a few brands of mobile hard disks on the market now. Mechanical hard disks and mobile hard disks under 500G have no cost performance, and 1TB has the highest cost performance, with a price of more than 400 yuan. I have been doing Western Digital and Seagate hard drives, and the quality of hard drives and after-sales maintenance are very high (of course, Toshiba or Samsung brands can also be considered), and the size is of course 2.5 inches, which is the most convenient! In addition, if you really don't need so much storage space, the size below 500G can fully meet your needs. You can also consider a smaller size, that is, 1.8 inch mobile hard disk, but neither Seagate nor Western Digital will make mobile hard disks of this size. You can choose Newman brand which has been studied for a long time in the field of 1.8 inch mobile hard disk, such as: 60GB Newman Minicard Jiyun 1.8 inch mobile hard disk. If it's not very useful, use Seagate. Seagate is faster than western digital. If your mobile hard disk is damaged and your data is lost in the future, you can find our Aite Data Recovery Center as soon as possible. Fifteen years of hard disk data recovery experience, Aite data recovery can definitely help you solve the problem of data recovery. I hope it helps you.

Question 8: What brand of mobile hard disk is the best? There are not many hard disk brands, only two giants.

Western Digital and Seagate. Together, these two brands account for more than 95% of the market.

The remaining 5% are only Samsung, Toshiba and Hitachi. No, Hitachi hard disk has been delisted some time ago.

For the mobile hard disk market, there are a little more brands. But only Western Digital, Seagate and Toshiba have their own brands of hard disks. Samsung doesn't produce mobile hard disks, and Samsung's original products on the market are all knockoffs.

If you like Toshiba and Seagate, there is no doubt that you will choose Seagate. Now the stronger the brand is, the weaker it is. It is very likely that today's Hitachi hard disk is tomorrow's Toshiba hard disk.

If you are interested in Seagate and Western Digital, this is not easy to choose, and high-quality brands are the same. Look outside and watch function.

Question 9: What brand of mobile hard disk is easy to buy? One is Hitachi (bought by the university), and it feels ordinary to use. The other is Seagate ST1t1tbst31000528as7200.12 (currently in use). Seagate's hard disk can be said to be the best among hard disks. I also want to buy a 3.5-inch hard disk extraction box, which is good in ORICO. The hard disk is bought from Taobao, and the price is about 400. I spent less than 200 pounds on this box. It may be cheaper now. If you think 1T is too big to use, you can buy a 500G one, which is easy to carry. Even the box is about 400. Of course, I still recommend the professional Seagate brand.

Question 10: What is a good removable hard disk? Western Digital and Seagate mobile hard disk are better.

MobileHarddisk, as its name implies, is a storage product that uses hard disk as storage medium, exchanges large-capacity data between computers, and emphasizes portability. The vast majority of mobile hard disks in the market are based on standard hard disks, and only a few are micro hard disks (1.8 inch hard disks, etc. ), but the price factor determines whether the mainstream mobile hard disk is based on the standard notebook hard disk.

Because the hard disk is used as the storage medium, the data reading and writing method of the mobile hard disk is the same as that of the standard IDE hard disk. Mobile hard disks mostly use faster transmission interfaces such as USB, IEEE 1394, which can transmit data with the system at a higher speed.

To encrypt the data on the mobile hard disk, you can try USB Super Encryption 3000. The software is green and free of installation. If you put the software on a USB flash drive, you can transfer it to other computers with a mobile hard disk. The encryption speed is fast and the security is high.

Which brand of mobile hard disk should I buy?

Seagate and Western Digital mobile hard disks have their own advantages, and users can purchase them as needed. Seagate and Western Digital are both super giants in the field of mechanical hard disks. Both companies have products with different price grades, and there is no difference in use. From the data point of view, the failure rate of western digital is lower; From the after-sales point of view, Seagate is better after-sales.

Mobile hard disk purchase guide:

1, size

1.8 inch mobile hard disk, suitable for business users who pursue ultra-mobility and portability. 3.5-inch mobile hard disk has outstanding stability and shock resistance, which is more suitable for business users on business trips. For most users, it is recommended to buy the most mainstream 2.5-inch mobile hard disk, which has relatively high cost performance and balanced performance.

2. Materials

It is inevitable that the mobile hard disk will collide during handling. It is recommended to buy a mobile hard disk with ABS engineering plastic shell, which should be slightly larger to ensure sufficient heat dissipation space inside, suitable for users who pursue good heat dissipation performance. If it is necessary to buy a mobile hard disk with a metal shell, then it is best to buy a protective sleeve with good seismic performance at the same time. Metal material has good texture and the best heat dissipation performance.

3. Capacity

The size of the capacity is related to the storage needs of users. It is suggested that office workers buy 256GB, 5 12GB mobile hard disks for storing work materials. For some designers, photographers and people engaged in computer programming, there is indeed a relatively large storage demand, requiring a large-capacity mobile hard disk of 1-2TB. Moviegoers and game lovers can choose a larger 4TB5TB mobile hard disk.

4. Transmission speed

For storing files, the mainstream USB3.0 interface is enough. For photographers or movie lovers who transmit a lot of data, it is recommended to buy USB3. 1 extremely fast mobile hard disk. As for the hard disk of Lightning III protocol, the quantity on the market is relatively small and the price is high.

What kind of mobile hard disk is better?

Personally, I think Western Digital mobile hard disk is better.

From the appearance, Western Digital Mobile Hard Disk and Seagate both adopt quite solid color matching, and both products provide up to five color choices, which is enough to meet the choices of more consumers. In the design of appearance, the Western Digital mobile hard disk is more rounded, while Seagate's edges and corners are smaller and more tough.

The advantages of Western Digital mobile hard disk in all aspects are also very obvious. But this does not mean that Seagate's mobile hard drive is not attractive at all. According to the requirements of different functions of mobile hard disk, the choice of mobile hard disk is also different. Therefore, when choosing these two different brands of mobile hard disks, we need to combine our own needs and choose the product that suits us best.

Seagate hard drives are generally faster, more fluent in reading and writing, and generally lighter. Wd hard disk is generally stable, and the loss rate is relatively low. The volume will be slightly thicker than Seagate's. Data is more important, and the speed requirement is particularly high. It is recommended to buy wd hard disk. The gap between Seagate and western data is really small. There is basically no difference in the use process. Seagate's sales are better than Western Digital.

Because these two interfaces are not plug and play, they cannot be used as external interfaces. You should choose USB or ESATA interface. As for what interface in the hard disk box does not affect the actual use, you don't need to care at all. The speed is generally 5400 and 7200, the latter is of course faster. Seagate Digital Hitachi has its own mobile hard disk.

Difference between Seagate and Western Digital Mobile Hard Disk

The western digital mobile hard disk MyPassportEssential is only110× 83x15mm, which is obviously shorter than FreeAgentGoFlex's11× 83x14mm, plus us.

In the interface part, MyPassportEssential and FreeAgentGoFlex adopt completely different designs, among which MyPassportEssential adopts an integrated design, and the interface is on the fuselage without any accessories. FreeAgentGoFlex's body only provides SATA interface, and if it needs to be converted into USB3.0 interface, an adapter needs to be added.
