Testing – Sandra & ATTO
Keep in mind for testing the advertised speeds for this drive are 4800 MB/s read and 4200 MB/s write.

Our first test is SiSoftware Sandra’s Physical Disks benchmark. We run both the read performance test.

ATTO Disk Benchmark measures transfer rates across specific lengths. ATTO uses RAW data, our transfer sizes ranged from 0.5 to 8192kb. ATTO is usually our definitive benchmark for solid state drives.
