Benchmarks

Crystal Disk Mark benchmark at 1GB test size:

Unlike CrystalDiskMark, the ATTO disk benchmark is a 32-bit compressible data benchmark that measures read and write speeds across various file transfer sizes from 512B to 64MB to show SSD behavior.

Sequential tests with Crystal Disk Mark with both empty drive and 75% loaded drive were rather impressive. On the bare drive, I saw read speeds up to 3502 MB/s and write speeds up to 1905 MB/s which is pretty close to the advertised speeds. When the drive was loaded up to 75% the sequential speeds dropped but not by much. Sequential read speeds were observed up to 3330 MB/s and write speeds staid pretty much the same at 1913 MB/s.

Looking at the benchmark data from ATTO Disk Benchmark I saw good performance data from both bare drive tests and loaded drive tests. In both cases, you can see cache dips on when the cache was filled up and emptied. This is a normal function of the cache. Under the 75% load, I do see a dip in the write performance with ATTO at around 4MB. I think the data overall looks pretty good for TLC NAND.
