1. Performance measured using Iometer with Queue Depth 32. Measurements are performed on
8 GB of Logical Block Address (LBA) range.
2. Performance measured with incompressible data using AS-SSD* benchmark, where
MB/s = 1,048,576 bytes/second.
Notes: 1. Based on sequential 4 KB using Iometer with Queue Depth 1 workload with compressible (non-random) data pattern.
Write Cache Enabled.
2. Power On To Ready time assumes proper shutdown.
