The capacity of the product names for the drives is based on the assumption that 1MB = 1,0002 bytes, while the user capacity for each drive is based on the assumption that 1MB = 1,0242 bytes. Furthermore, OS file management overhead will reduce the actual usable capacity.

The user capacity is constant regardless of the drive size (2.5"/3.5"), the SSD type (NVMe SSD and SAS SSD), or the encryption support (SED).
