What should I pay attention to when I want to replace my old computer with SSD solid state drive?

1. You can use the sata2 interface (as for the field sata2? Sata3 is the same, the key depends on the interface), although ssd performance can not be fully played, it should also be significantly improved.

I don't know if your old hard disk is sata. If it seems that no special settings are needed, just set the ssd boot in the bios. To be on the safe side, you can unplug the old hard disk and install the system first. Besides, I usually drive ahci.

3. There are shelves with extension 3.5 for sale.

Extended data:

Solid-state hard disk (SSD) is a hard disk composed of an array of solid-state electronic storage chips, which is composed of a control unit and a storage unit (FLASH chip and DRAM chip).

Solid-state hard disk is exactly the same as ordinary hard disk in terms of interface, function and usage, and the product shape and size are also exactly the same as ordinary hard disk. Widely used in military, vehicle, industrial control, video monitoring, network monitoring, network terminals, electric power, medical care, aviation, navigation equipment and other fields.

The working temperature range of the chip is very wide, including commercial products (0~70℃) and industrial products (-40~85℃). Although the cost is high, it is gradually spreading to DIY market. Because solid-state hard disk technology is different from traditional hard disk technology, there are many emerging memory manufacturers.

Manufacturers only need to buy NAND memory and cooperate with appropriate control chips to manufacture solid-state hard disks. SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, NGFF interface, CFast interface and SFF-8639 interface are widely used in the new generation of solid state drives.

Solid-state disk based on flash memory is the main category of solid-state disk, and its internal structure is very simple. The main body of SSD is actually a PCB board, and the most basic accessories on this PCB board are control chip, cache chip (some low-end hard disks don't have cache chips) and flash memory chip for storing data.

There are many kinds of main control chips, including LSISandForce, Indilinx, JMicron, Marvell, Qunlian, Goldendisk, Samsung and Intel. The main control chip is the brain of the SSD. Its function is to distribute the load of data on each flash memory chip reasonably, and to undertake the transmission of the whole data and connect the flash memory chip with the external SATA interface.

The capabilities of different masters are very different, such as data processing capabilities, algorithms, read-write control of flash memory chips, etc., which will directly lead to the performance gap of solid-state hard disk products as high as dozens of times.
