Disclosures
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. Endurance rating based on DW/D using 4KiB random write workload over 5 years.
3. Performance will vary by capacity point, or with the changes in useable capacity. Consult product manual for further details. All performance measurements are in full sustained mode and are peak values. Preliminary and subject to change. 1MiB=1,048,576 bytes or 220, 1KiB= 1,024 bytes or 210.
4. Measured as 100% Random Read, 4KiB, QD=1, 99.99%.
5. MTBF and AFR specifications will be 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.
6. The warranty for the product will expire on the earlier of (i) the date when the flash media has reached one-percent (1%) of its remaining life or (ii) the expiration of the time period associated with the Product.
