Accessible capacity will vary from the stated capacity due to formatting, system software, and other factors.2 MTBF and AFR specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions for this drive model. MTBF and AFR ratings do not predict an individual drives reliability and do not constitute a warranty.3 Advanced Format drive: 4K (4096-byte) physical sectors4 Portion of buffer capacity used for drive firmware5 MiB/s is 220 bytes, MB/s is 106 bytes6 Excludes command overhead7 SATA models: 8K Queue Depth = 1 @ 40 IOPS, SAS models: 4K Queue Depth = 4 @ Max IOPS8 Idle specification is based on use of Idle_A
