Anonymous users2024-02-11This question is not difficult, and it is explained one by one.
1. U disk and mobile hard disk, the difference, the capacity must be the first. The capacity of the portable hard disk is much larger than that of the USB flash drive.
2. The disadvantage of U disk is that it has a small capacity and is easy to lose. The disadvantage of mobile hard disk is that it has high requirements for data cables, and the general data cable is plugged in, which is a bit unreadable by the computer. Easy to break. Can't fall. Handle with care.
3. The advantages of the U disk are small, it is too convenient to carry, and it is not afraid of small falls. The advantage of mobile hard disk is that it is easy to carry, has a large capacity, and can put a lot of important information in it, and is not afraid of computer poisoning and destroying the data inside. To put it bluntly, there is a spare tire.
4. Mobile hard disk is the first choice for important data. If you don't pay attention to the U disk, it's easy to forget where to put it and it's easy to lose.
If you're satisfied, bother.

Anonymous users2024-02-10No. I'll probably tell you about it:
1。The storage device used in the mobile hard disk is the inch and inch hard disk, which is the hard disk, because the hard disk is used as the storage core, so the capacity is easy to make a large one. The USB flash drive uses a flash chip as the storage core, so on objects as big as fingernails, 16G is close to the highest capacity.
2。In terms of shock resistance, mobile hard disks are much inferior, because the use of hard disks as storage devices, heavy collisions, etc., may lead to bad sectors in the hard disk. And the flash memory chip in this regard,It's very good.,Almost can't be broken.。。。
I couldn't recognize the disk when I dropped my mobile hard drive from a 1-meter-high desk, but the USB flash drive often fell and it didn't happen.
3。In the field of new mobile hard disks, there are three-proof hard disks, but they are much more expensive than ordinary mobile hard disks.

Anonymous users2024-02-09One: The difference is that the mobile hard disk has a large capacity. Two: Huh. Three: The U disk is very small, but the hard disk has more available space in proportion Four: If it is not very large, use the U disk.

Anonymous users2024-02-08Why is a portable hard drive faster than a USB flash drive.
Portable hard drives and USB flash drives are common external storage devices, both of which can be used to store and transfer files. However, in actual use, the transfer speed of portable hard disk is usually faster than that of USB flash drive, which is caused by the following reasons.
The storage capacity is different.
Portable hard drives typically have a much larger storage capacity than USB flash drives, which means they require more disk space to store data. Larger storage capacities usually require faster read and write speeds to transfer data, so portable hard drives are faster than USB flash drives.
The data transmission interface is different.
Portable hard drives usually use an interface or higher, while USB flash drives usually use an interface or lower. The transfer speed of the interface is much faster than the interface, which is one of the reasons why the mobile hard disk is faster than the USB flash drive.
The mechanical structure is different.
Portable hard drives usually have the structure of a mechanical hard drive, which has a high-speed spinning disk and read/write head. In contrast, USB flash drives typically have a solid-state drive (SSD) structure and do not have spinning disks and read/write heads. HDDs have slower read and write speeds than SSD HDDs, but HDDs have a larger storage capacity.
Therefore, the read and write speed of a portable hard disk is slightly slower than that of a USB flash drive, but the storage capacity is larger.
To sum up, there are many reasons why mobile hard drives are faster than USB flash drives, including storage capacity, data transmission interface, and mechanical structure. If you need high-capacity storage and fast file transfers, a mobile hard-cover tremor drive may be a better option.

Anonymous users2024-02-07Hard drives are not good for carrying around, and a cable is required to connect to a computer. However, the capacity of hard disks is generally between 500G-1TB (1024G), which can store a large number of movies, games, etc.
The USB flash drive is portable and does not require a data cable, but the storage capacity is small. Generally between 16g-128g.
Hope it helps.
The storage method is not the same.
Mobile hard disk is essentially a hard disk, and the USB disk is essentially a flash memory EEPROM bar, and the mobile hard disk is relatively large, the USB disk is relatively small (size) The unit capacity of the mobile hard disk is much cheaper than the U disk, and the largest U disk is now only 2G, and the mobile hard disk is basically 40G or larger. >>>More
Personal point of view U disk, the capacity is relatively small, easy to carry, **low, but sometimes there is no way to copy one, although there are 8 16g, but relatively speaking** is not very good There are also cheap ones, but the quality is not known It all depends on luck. >>>More
Right-click on my computer - management - disk management - after finding your drive letter, format it first, and then don't save files on it, and then use EasyRecovery for data recovery, remember to choose "formatted recovery", it's OK, after the file recovery is completed, use XP's built-in partition tool to partition it, just right-click on my computer--manage-disk management--After finding your drive letter, deal with it according to your actual situation, your situation should be right-click on the drive letter to choose a new partition or what, specific and forgotten, rest assured It won't break the disk.
Of course, as long as it's driverless.
Interface standards are the same all over the world. >>>More
On the basis of traditional mobile hard disks, smart mobile hard disks can emit Wi-Fi, and mobile phones and tablets can read and write hard disk data through Wi-Fi. However, the reason why it's really smart is that it has an embedded CPU that can replace the computer itself to connect to the Internet and automatically interact with various cloud services, such as cloud offline** and so on.
