1 One megabyte (MB) is equal to one million bytes, one gigabyte (GB) is equal to 1,000MB (one billion

bytes), and one terabyte (TB) is equal to 1,000GB (one trillion bytes) when referring to storage capacity. 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 drive’s reliability and do not constitute a warranty.

3 Advanced Format drive: 4K (4096-byte) physical sectors

4 Portion of buffer capacity used for drive firmware

5 MiB/s is 220 bytes, MB/s is 106 bytes

6 Excludes command overhead

7 SATA models: 8K Queue Depth = 1 @ 40 IOPS, SAS models: 4K Queue Depth = 4 @ Max IOPS

8 Idle specification is based on use of Idle_A
