Capacity
Notes: 1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.
LBA count shown represents total user storage capacity and will remain the same throughout the life of the drive.
The total usable capacity of the SSD may be less than the total physical capacity because a small portion of the capacity is
The total usable capacity of the SSD may be less than the total physical capacity because a small portion of the capacity is
