Limitations

Solid-state memory cells have an intrinsic, finite number of write cycles that each

cell can incur. As a result, each solid-state drive has a maximum amount of writes

it can be subjected to, documented as Total Bytes Written (TBW). IBM is not

responsible for replacement of hardware that has reached the maximum guaranteed

number of write cycles. This limit may be revealed as the SSD drive failing to

respond to system-generated commands or becoming incapable of being written

to. In general, it is important to distinguish enterprise value drives from enterprise

drives.

Enterprise drives have much higher write endurance and as a result can withstand

a greater number of writes over the lifetime of the device compared to enterprise

value level drives. SSD write endurance is an important factor to consider because

unlike spinning disk media, NAND flash has a finite number of program/erase cycles

it will accept. SSD write endurance is typically measured by the number of program/

erase cycles, or P/E cycles, each cell incurs over its lifetime, and per drive is listed

as Total Bytes Written (TBW) in the drive specification. This statistic can be used to

give an estimate of the drive's remaining life based on the workload to which the

drive will be subjected. The TBW value assigned to a solid-state drive is the total

bytes of written data (based on number of P/E cycles) a drive can be guaranteed to

complete. Reaching this limit does not cause the drive to immediately fail; it simply

denotes the maximum number of writes that can be guaranteed.
