2. Let's put it this way about the life of SSD chips. Don't listen to legends, believe in technological development. Regarding the theory of flash memory chips, SLC chips read and write 654.38+00,000 times, and MLC chips read and write 654.38+00,000 times. For example, a 1GB chip will break after reading and writing the 1GB file 65438+ million times, but do you always write or delete the 1GB file? If you can't write the file 1GB every time, you need a good controller to manage it intelligently. For example, every time you write 500MB, the control chip will divide the chip into two 500MB warehouses. If you write smaller or enlarge the capacity every time, your life will not double. This is Samsung's theory. I just give a simple example, but in fact, with the development of control chip and SSD flash memory chip, the life and speed will be greatly improved.
2. Regarding how to choose, I think the price and stability are the first choice. If you pursue speed, there is no fastest but faster. For example, SATA interface is 2.5 inches. Some time ago, magnesium light was emitted from c300, and the reading speed was 300-400MB/s, and it was written to 215 MB/s. It was not long before the SandForce SSD control chip came out, and the reading and writing speed instantly broke 500MB/s, which could not be broken. (You need to explain the SATAII interface and SATA3.0 interface here, just look at Baidu.). The SSD manufacturer AXD Shenzhen Anxinda Storage Technology Co., Ltd. revealed that the upcoming SATA2.5-inch SSD adopts the latest second-generation SandForce master control and the latest magnesium SLC chip and patented circuit. According to the internal test data, it should be the fastest SATA3.0 solid-state drive at present, and the estimated cost is not cheap. This is nothing. OCZ's PCIE interface SSD group is said to have a speed of 2-3 GB/s. God, it's terrible. Faster than DDR3.
Personally, I think it is enough for DIY users to install a 64GB SSD solid state drive and a HDD desktop for leverage.
If the motherboard does not support SATA3.0, the ex-factory price of AXD Anxinda's SATAII interface 64GB is only 559 yuan. Last time it was from
My friend's company bought one, and my friend said it was customized by their company. It is not only fast, but also extremely stable. I don't know the reserve price. If it is customized, it is estimated that it will be cheaper.
