Four points about SSD hard drive 1

 

SSD hard drive, because Taiwanese English call solid capacitors Solid and solit. The SSD consists of a control unit and a memory unit (FLASH chip, DRAM chip). SSD hard drive are exactly the same as ordinary hard disks in terms of interface specifications and definitions, functions and usage methods, and are basically consistent with ordinary hard disks in terms of product appearance and size (the size and shape of the emerging U.2, M.2 and other forms of solid-state drives are completely different from SATA mechanical hard disks).

It is widely used in military, vehicle,industrial control,video surveillance,networksurveillance,network terminal,electric power,medical,aviation,navigation equipment and many other fields.

  1. Are there different levels of flash memory? Why is  U drive cheaper than  SSD hard drive?

True, flash memory has different quality, corresponding to different costs, just like CPUs. Udisk usually uses lower-grade flash memory. If you use Udisk as a hard disk, I think you will immediately feel the performance difference. In addition, there is a clear difference in reliability between good and bad flash memory. High-quality flash memory chips have a much lower chance of error throughout their life cycle. Although we can make inexpensive mobile hard drives with inexpensive flash memory, I think everyone understands that inexpensiveness is not good.

Have you got the necessary understanding of SSD hard drives? Simply put, although the current capacity is not the advantage of SSD solid state hard disk, but the speed, abnormality is related to your operating system operation, daily use of the part, if you use solid state hard disk to make the system disk that is generally improved!

  1. What is the determinant of the speed of the SSD hard drive? Where is the current bottleneck?

The performance of any sSSD hard drive is determined by the original flash bandwidth, the efficiency of the loss balancing algorithm (firmware), and the interfaces (SATA, PCI-E, etc.). With the SATA interface speed card there, it doesn’t make sense to have a strong flash memory performance. Like other manufacturers in the industry, we will gradually improve the performance of SSD hard drive. Although it cannot be said that SSDs are “catching up” with the SATA-III standard, they will certainly benefit from the introduction of the third generation SATA standard.

  1. Who consumes more power than traditional hard disks?

I’ve seen some reports that state drives consume more power than traditional hard drives, but there are also some surveys that show SSDs save more power. Generally speaking, SSDs and HDDs consume similar power when they are working under the same high load or in the same dormant state. However, solid-state hard disks still have some advantages in power performance, such as no rotating motor inside the SSD hard drive, so the power consumption in idle state is significantly lower. Second, since there is no start time for the speed increase or decrease, the time for SSD to enter or wake up from the sleep state is shorter and more frequent. Ultimately, the solid-state hard disk can do the same work in less light, so it hibernates earlier. These advantages make solid-state hard disks really save power in practice than traditional hard disks.

  1. Why do everyone use SSD hard drive MLC granules? Is SLC not faster?

Yes, SLC NAND flash memory is faster, but only when you compare face to face can you see a significant difference. Moreover, as long as parallel read-write mechanisms are used on a large scale, MLC can also achieve high speed. In such a situation, SSD hard drive vendors will certainly pay more attention to cost and capacity issues, and MLC’s low cost and large capacity will become an advantage.
