Silicon Power A55 256GB 3D NAND SSD Review

Storage/SSD by stefan @ 2017-11-25

As we have seen before with TLC NAND SSDs, the SLC cache is used first for gaining a respectable speed boost and once this one gets filled up, the write speed will start dropping gradually, sometimes under 100MB/s. This particular aspect does not recommend the drive if our workload does imply writing large files frequently onto the drive, but even when we are writing straight to TLC, the access times do remain smaller versus mechanical drives. For a better compatibility, A55 256GB does ship with a 7mm form factor, while the integrated DRAMless Silicon Motion SM2258XT controller does come with support for TRIM command and Garbage Collection technology.
