Brief Specification
Definition of capacity: Toshiba defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A
computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 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.
GT/s：Giga Transfers per second (The transfer speed only for effectiveness data)
A kibibyte (KiB) means 210 or 1,024 bytes, a mebibyte (MiB) means 220 or 1,048,576 bytes and a gibibyte (GiB) means 230 or 1,073,741,824 bytes.
MTTF (Mean Time to Failure) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may
not accurately reflect actual operation. Actual operating life of the product may be different from the MTTF.
DWPD: Drive Write Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day for five years, the stated
product warranty period. Actual results may vary due to system configuration, usage and other factors.
The performance is measured in sustained condition.
Read and write speed may vary depending on the host device, read and write conditions and file size.
IOPS: Input Output Per Second (or the number of I/O operations per second)
2 / 2
