has much impact" to the specific situation, add that: U Disk Service life is written, read as if it is unlimited. So choose SLC or MLC's good quality USB drive can not worry about the service life.
More than 32G USB drive volume produced into FAT32 the only problem is that you cannot copy a single file that is larger than 4G, prompting insufficient space. exFAT requires a system patch before it can be opened, or the hint needs to be formatted. EXFAT
Solid-state hard disk because many friends have never used, coupled with a lack of comprehensive understanding, so the late use of solid-state hard disk will often encounter much more confusing things, such as a net friend asked the SSD 4k what does it mean?
4K meaning, simple is that partition time by 4K size to allocate each small module, such a hard disk is assigned to n more than 4K small partition, the purpose is to improve the reading efficiency of SSD. 4K-aligned hard drive, read write e
does not mean that the hard disk can not be used, but performance will be reduced, there is noise, such as driving a car, the mechanical structure will appear aging, so need maintenance, but mechanical hard disk use for 5-10 years completely no problem, or even more.
Solid-state hard disk life standard is generally written or written capacity, the calculation of capacity units are not intuitive, including 4 K, 8K of random write capacity, usually in TB, PB units to calculate, the general profe
reason for this is that SSDs may be transmitting data as we reboot, and the data will have an opportunity to go wrong because of our restart action, which can also affect HDD and SSD
As we have mentioned in many pieces of technical articles, the biggest difference between solid-state and mechanical hard drives is that you must first erase the files of an index area, then write, and the mechanical hard drive can be covered directly. and the MLC flash particles used by consumption-grade SSD are
accommodated through memory clusters. In demanding performance environments, memory is more attractive than SSDs.Disk development in the 50 's, despite the increasing disk density, the core architecture of the disk is basically unchanged, or the robotic arm moving the head to the disc on the track to read data.After the mechanical disk, there is a solid state drive (SSD), the SSD has no moving parts, and I/O latency is low. Currently, most SSDs are implemented with NAND flash.SSDs have signific

The combination of red and yellow is a simple and safe color. It is often used in fresh and Dynamic Webpage designs such as food, leisure and fashion. Red and yellow are adjacent colors and their brightness and purity are close to each other. Therefore, you can coordinate, soften, and feel comfortable on the webpage.

Assuming that a 128G SSD is written to 40G per day (which is impossible for a typical home user), it can be used for more than 20 years.2, TLC Life, is the MLC half or One-third. This means that life expectancy is shortened by three times times.3, the life of SLC, is 10,000 times P/E, is more than three times times the MLC.The advantages of SSDs are: The biggest is the speed, seismic, and so onDisadvantages are expe

the promotion of SSD hard disks, the performance gap will be reduced. I agree with this idea for the moment, but don't forget that the security impact of this solution will never be solved. Of course, if you use an SSD hard disk, it will bring another and more serious problem, because the MLC chip has a very short life, it can only be written about 0.1 million times, and although the SLC chip is growing much, it is still several orders of magnitude d
