One Gigabyte (1GB) means 10
9
= 1,000,000,000 bytes, one Terabyte (TB) means 10
12
=
1,000,000,000,000 bytes, and one Petabyte (1PB) means 10
15
= 1,000,000,000,000 bytes using
powers of 10. A computer operating system, however, reports storage capacity using powers
of 2 for the definition of 1GB = 2
30
= 1,073,741,824 bytes, 1TB = 2
40
= 1,099,511,627,776 bytes,
and 1PB = 2
50
= 1,125,899,906,842,624 bytes, and therefore shows less storage capacity.
Available storage capacity (including examples of various media files) will vary based on file size,
formatting, settings, software and operating system, such as Microsoft Operating System and/
or pre-installed software applications, or media content. Actual formatted capacity may vary.

4KB random read/write I/O performance.
3
MB/s = 1,024 x 1,024 Bytes/second.

Testing conditions for these performance numbers stated in the table are as follows: Random
Read: Queue depth=32, 4KB-aligned LBA; Random Write: Drive at steady state (preconditioned
with 4KB random writes), Queue depth=32, 4KB-aligned LBA; Sequential Read: Queue
depth=32, 4KB-aligned LBA; Sequential Write: Drive at steady state (preconditioned with 64KB
Sequential writes), Queue depth=32, 4KB-aligned LBA; Random combined: Drive at steady state
(preconditioned with 4KB random writes), Queue depth=32, 4KB-aligned LBA; Please reference
product manual for additional for additional information on test setup and configuration.
5
Warranty for the 100GB capacity point is 5 years or 8.2PB total write capacity, whichever occurs
first.
