How to select the data of mobile hard disk

I format the mobile hard disk and select NTFS. There is an allocation unit size below, 5 12 bytes, 4096 bytes. What is the difference? What should I choose?

Generally, NTFS format is selected by default, because NTFS format supports a single file above 4G. If the USB flash drive is a small 4G or 8G USB flash drive, you can choose FAT32 format. If you want to store some compatible files on a large USB flash drive, you can use EXFAT format. Detailed steps:

1. First, insert a USB flash drive, right-click this computer on the desktop of the computer, and click Open.

You can see many partitions in the computer. In general, the USB flash drive you insert is the last drive letter. As you can see, I use a 32G USB flash drive.

3. Right-click the USB flash drive, and then click Format in the menu.

4. First, you can see the total capacity of the U disk in the format window, and you can see three formats in the file system. At present, the storage capacity of U disk is relatively large, so NTFS format is generally selected by default, because NTFS format supports a single file above 4G.

If your USB flash drive is a small 4G or 8G USB flash drive, you can choose FAT32 format. If you want to store some compatible files on a large USB flash drive, you can use EXFAT format.

To sum up, in general, NTFS is enough. We see that there is another option under the file system, which is to allocate the unit size. What does this do?

6. The file stored on the U disk is divided into several blocks according to the size of this allocation unit and stored on the disk. If each block is divided into smaller blocks, the transmission speed will be slower, but the occupied blocks will be less; Conversely, the larger each block, the faster the transmission speed, but the larger the space occupied.

So if you only save a small file of songs, you can set a single grid smaller (16K), but usually you just need to set it to the default configuration size.

7, check the quick format, and then click start, wait a moment to format the USB flash drive.

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, Western Digital mobile hard disk is more rounded, while Seagate's edges and corners are smaller, which makes it 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.

Mobile hard disk purchase?

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 data should I choose for the format of 2T mobile hard disk? 1048 or 4800?

When choosing the formatting parameters of mobile hard disk, you should decide according to your actual needs. First of all, you need to know what you mean by "1048" and "4800". If you mean the size of the cluster, it should be wrong here, because the size of the cluster is usually a power of 2, such as 5 12 bytes, 1024 bytes (1KB), 2048 bytes (2KB), 4096 bytes (4KB) and so on.

When choosing the cluster size, smaller clusters will reduce the waste of storage space, but may cause files scattered on the disk, thus reducing the speed of data reading and writing. Larger cluster size can improve data transmission speed, but it may waste more storage space.

For 2TB mobile hard disk, NTFS file system is recommended, because it has good compatibility, security and the ability to support large files. When choosing the cluster size, we can consider using the cluster size of 4096 bytes (4KB), which is the default value of NTFS file system, which can not only take into account the utilization of storage space, but also ensure better transmission speed.

Please note that if you need to share the mobile hard disk between Mac and Windows systems, you can consider using exFAT file system, which is more compatible among multiple operating systems. Similarly, when choosing a cluster size, you can consider using a cluster size of 4096 bytes (4KB) as the default setting.

How to choose a mobile hard disk

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. Mobile hard disks mostly use faster transmission interfaces such as USB, IEEE 1394, which can transmit data with the system at a higher speed. So how do we choose when buying a mobile hard disk? Come and have a look with me.

1. capacity

Dear friends, when choosing a mobile hard disk, the most important thing is its capacity. Capacity is related to our storage needs. We should choose its capacity according to our actual use. There are also 500G, 1TB, 2TB hard disks on the market. If you want to store your important documents, photos and favorite songs, you can choose a bigger one (I personally prefer a bigger one because I need a lot of information for my work), which meets our needs.

2. Volume

The size of the hard disk will also affect our use to some extent. It's too big for us to carry. In order to avoid this situation, try to choose a small and light one, which is more convenient for us to carry out or use in the office.

3. Backup method

Whether it is life or work, I hope that the simpler the better. We also hope to have a convenient way to back up data. When choosing a hard disk, one-click backup is not only simple, but also flexible, so we can operate it easily.

Step 4 live in harmony

If the hard disk can be used interchangeably on PC or Mac at the same time, there is no need for format conversion. So when we choose a hard disk, we should also pay attention to its compatibility. Isn't it convenient to use?

Step 5 show up

When we use a hard disk, we often come into contact with its appearance. Therefore, you can choose a shell with frosted particles, which can play an anti-slip role and prevent some friends from sweating and falling to the ground. The hard disk made of this material is also resistant to dirt, even if it is accidentally stained with some stains.

6. Function

We should also pay attention to its other functions when purchasing mobile hard disk. Try to choose something that is shockproof, encrypted, antivirus and waterproof. Although they are not decisive factors, with their protection, our data will be more secure and we don't have to worry about data loss.
