Which file system is better to use for a portable hard disk?

In contrast, it is better to store files with a portable hard drive.

In terms of capacity, the USB flash drive has not yet broken through the bottleneck of 128GB. The maximum capacity of mobile hard drives has reached 2000GB. Portable hard drives can use NTFS file system, which supports encryption and quota functions.

Although some Kingston USB flash drives can also be formatted into NTFS format, the NTFS file system format is more harmful to the chip if it is used on a USB flash drive. The only advantage of a USB flash drive over a mobile hard disk is that it is easy to carry. There is another storage medium that I would like to recommend to you, solid state drives.

I just don't know if you can afford it, it's quite expensive.

It has the advantages of both a USB flash drive and a portable hard drive. And because there is something spinning at high speed (5400 rpm) in the mobile hard drive, the data may be gone if you hit something. There is also a USB flash drive, its transmission rate, is really annoying.

The most efficient way to store files:

1. If it is the stability of computer files, as long as you don't save the C disk, you can do it, because the C disk is often the area where the system disk is located, which has an impact on the system space occupation and the system.

2. If it is security, it is recommended to install anti-virus software to check and kill viruses on the files stored on the computer to ensure that it does not pose a threat to the computer.

3. If it is confidentiality, it is recommended to use professional security and confidentiality software to package and process, and the archiving of files is mainly based on separate categories, that is, movies, audio and video, text, **, establish several folders, store them independently, or compress some documents that are not often used for backup, develop a good storage habit, and it is also very convenient for future management. <>

FAT16, FAT32, and NTFS are the three most common file systems.

FAT16: In the past, DOS and Windows 95 used FAT16 file system, and now commonly used Windows 98 and other systems support FAT16 file system. It can manage partitions up to 2GB in size, but each partition can only have up to 65,525 clusters.

FAT32: With the advent of large-capacity hard disks, starting from Windows98, FAT32 became popular, it is an enhanced version of FAT16, which can support 2T partitions, and the clusters used by FAT32 are smaller than those of Brother Potato FAT16, thus effectively saving hard disk space;

NTFS: Microsoft.

It is better to use an SSD for a portable hard drive, which has the following advantages compared to a mechanical hard drive

1. No magnetic head, fast random reading, fast reading and writing speed.

Using flash memory as the storage medium, the read and write speed is faster than that of HDD, saving time for copying data.

2. No noise, low heating.

Because there is no mechanical motor and fan, the noise level is 0 dB when working, which is quieter and the power consumption is lower than that of traditional hard drives.

3. Shockproof and anti-fall, data is safer.

There are no mechanical moving parts inside, no mechanical failure will occur, and there is no fear of collision, shock, vibration. In this way, even when moving at high speeds or even with flipping and tilting, it will not affect normal use.

4. Large operating temperature range.

HDDs can only work in the range of 5 to 55 degrees Celsius, while most SSDs can work at 10-70 degrees Celsius.

5. Small and lightweight.

Compared to regular 1 8-inch HDDs, SSDs are lighter in weight and convenient to carry around.

Precautions for the purchase of mobile hard disks:

1. Mobile hard disk shell.

The materials of mobile hard disk enclosures are generally divided into metal and plastic. Generally speaking, the compressive and heat dissipation performance of the metal shell will be better, while the plastic shell has relatively better advantages in terms of shock resistance and weight. Therefore, choose a metal case for mechanical hard disks and plastic shells for solid state drives.

2. PCB board blind circle control chip.

The control chip on the PCB of the mobile hard disk is directly related to the read and write performance and stability of the product. At present, the control chip is mainly divided into two grades: high and low. High-end chips** are more expensive, with excellent stability and compatibility, suitable for demanding users.

The stability and data transmission performance of the low-end chip are relatively poor, but they are also enough to cope with the daily work needs.

3. The external grinding and dismantling of the hard disk enclosure.

At present, the common interfaces of mobile hard disks include the eSATA interface.
