As we all know, SSD has great advantages of anti-seismic, no mechanical delay and high IPOS. However, as the physical characteristics of flash memory, the chip needs to be erased before writing, and the erasure times of flash memory are limited, the structure of full flash memory will greatly shorten the service life of SSD and increase the cost.


Is there any way to combine the high IPOS of SSD and high capacity, low-cost features of  HDD to comprehensively improve the performance for storage?


The following two solutions are recommended for your reference:

2 * M.2 SSD  &  2 * SATA HDD 

M.2 SSD is made to RAID 1 to be system disk, so that to improve the startup and running speed of the system.
SATA HDD is set up as extension disk to secure data storage and increase capacity space.
