FUJITSU drives have a 512k buffer that is used for firmware.
ZERO, ZIPPO, NADA, NOWAY is any of it used for buffering.
Translation equal to the original Celeron 300A.
Just because a drive claims to have cache, doesnot mean it is usable.
You need to ask yourself, caching what????
In this case, the firmware for the drive.
