Advantages and disadvantages are as follows
advantage
1. Fast. The theoretical speed of Huawei SSDS is more than 10 times that of ordinary SATA disks, and the actual read and write speed is usually more than 5 times that of SATA disks and more than 20 times that of ordinary U disks.
2. Small size and light weight. Huawei's SSD memory chips are so small that even with the case, control circuits and interface chips, the final product is less than a third the size of a regular portable hard drive and probably not much bigger than a credit card in the palm of your hand (but a little thicker).
3. No noise, low failure rate. SSDS work a bit like U disks, because SSDS do not need to rely on mechanical magnetic heads for data access, and do not need to rely on those delicate high-density disks, so SSDS can do noiseless work, and will not be as easy to break as ordinary hard disks.
drawback
1. The price is high. Compared with ordinary SATA mobile hard drives, the unit price of solid-state mobile hard drives is about 1 times higher. On the market, the price of Huawei's solid-state mobile hard disk is usually more than 800 yuan, the capacity is usually only 256GB or 128GB, and the price per GB is about 4 yuan, while the price of ordinary SATA hard disk per GB is about 0.3 yuan, and the unit capacity price is more than 10 times higher.
2. Depends on computer and interface performance. Although solid state mobile hard disk has N times the speed of ordinary hard disk, its read and write speed is still restricted by computer performance and interface speed. If it is an old computer, or a computer that does not support the USB3.0 interface, then the performance of the SSD may not be the best.
3. Data recovery is difficult. Due to the principle of data storage, when a small probability of physical damage occurs, it is extremely difficult to recover the data of SSDS. When the traditional disk disk mechanical failure and circuit failure, in theory, it is possible to use technical means to recover all or part of the data, but if the solid state disk physical damage, then the probability of data recovery may be zero.
