When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your computer’s operating system may use a different standard of measurement and report
a lower capacity. In addition, some of the listed capacity is used for formatti ng and other funct ions, and thus will not be available for data storage. Actual quantities will vary based on various factors, including file size, file
format, features and application software. Actual data rates may vary depending on operating environment and other factors. The export or re-export of hardware or software containing encryption may be regulated by

NOTE Information on performance:
0% refers to data that cannot be compressed and 20% refers to data for
which the size can be losslessly compressed by 20%. Performance values
shown is based on data compressibility values of 0% and 20% as set with
VDBench.
The scripts that were used to arrive at these measurements are available
on request.
MB is 10^6 bytes. MB/s = 10^6 bytes/sec.
4 KB = 4,096 bytes, 8 KB = 8,192 bytes.
All workloads set to 4 KB alignment.
All metrics represent sustained values, across full LBA range.
Drive write cache is active and protected by Power Loss Data Protection
(PLDP) feature.
Performance test precondition: The drive is preconditioned with 2x drive
capacity 128 KB sequential write IOs, prior to sequential testing, followed
by 6 hours per 1 TB drive capacity of 4K random write IOs, at queue depth
32, prior to random testing.
Results obtained with a direct SATA port connection to host and may vary
with capacity, endurance and system configuration. The HBA used could
also affect measured results.
