*Display of total bytes varies from file systems, which means not all of the bytes can be used for storage.

**Notes: 1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.

LBA count addressed in the table above indicates total user storage capacity and will remain the same throughout the lifespan of the

device. However, the total usable capacity of the SSD is most likely to be less than the total physical capacity because a small portion

of the capacity is reserved for device maintenance usages.
