Solid state hard disk PK memory virtual hard disk

is very different, no matter from speed and application, the memory reading speed can reach more than 15,000 M/S, the writing speed is about 13000, and now the best solid state hard disk reading speed can also be More than 400 M /S, the writing speed is lower, it is more than 200. Can only be described by the difference between the days. It’s just that the system home says that it’s not as good as experimenting with yourself. I suggest you use the memory virtual hard disk out and then use the hard disk test software to know.

but also said the gap between the speed, the greater the gap between the application, because the chip memory using DRAM chips, DRAM can hold data for a short time. In order to maintain data, DRAM uses capacitor storage, so it must be refreshed once in a while. If the memory unit is not refreshed, the stored information will be lost. (Shutdown will lose data)

SSDs, flash-based solid state drives are the main categories of SSDs, its internal structure is very simple, solid-state hard drive inside the body is actually a PCB board, but this piece of PCB board The most basic accessories are control chips, cache chips, and flash chips for storing data. It is a U disk with a larger capacity and a faster speed.

currently on the market the more common solid-state drives have Indilinx, SandForce, JMicron, Marvell, Samsung and Intel and other chip master. The main control chip is the brain of the solid-state hard disk. Its role is to properly allocate the load of data on each flash memory chip, and the second is to undertake the entire data transfer, connect the flash memory chip and the external SATA interface. The ability of different masters is very different. There will be very different data processing capabilities, algorithms, and read and write control of flash chips. This will directly lead to a tens of times the performance difference of SSD products.
