We’ve covered TRIMcheck in the past. It is a great tool that easily lets us see if TRIM is actually functioning on a SSD volume in your system.
As can be seen in the screenshot above, TRIMcheck’s result is positive. TRIM is indeed working.
ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.
FW 0208a (TLC)
FW 0206b (MLC)
As much as we like to see 4k transfer a bit higher, the overall data transfer speeds of 530MB/s read and 565MB/s write are excellent. We are also seeing very similar results from both sets of firmware.
