Notes:
Micron’s SSDs incorporate advanced technology for defect and error management.
They use various combinations of hardware-based error correction algorithms and firm-
ware-based static and dynamic wear-leveling algorithms.
Over the life of the SSD, uncorrectable errors may occur. An uncorrectable error is de-
fined as data that is reported as successfully programmed to the SSD but when it is read
out of the SSD, the data differs from what was programmed.
Table 8: Uncorrectable Bit Error Rate
Mean time between failures (MTBFs) for the SSD can be predicted based on the compo-
nent reliability data using the methods referenced in the Telcordia SR-332 reliability
prediction procedures for electronic equipment.
Table 9: MTBFs
Endurance for the SSD can be predicted based on the usage conditons applied to the
device, the internal NAND component cycles, the write amplification factor, and the wear-
leveling efficency of the drive. The table below shows the drive lifetime for each SSD
density based on predefined usage conditions.

1. Total bytes written calculated with the drive 90% full.

3. GB/day can be calculated by dividing the total bytes written value by (365 × number of
