HDD cache

Recommended Posts


I have 2x 1TB WD Caviar Black with 64MB Cache, but If I check in ATA option under one of this HDD for Cache it shows Unknown.

I have also 2 other WD Caviar Blue with 16Mb cache, for this one it shows corectly.

Due to limitations of ATA spec, most drives with 64MB cache cannot report their cache size in the ATA autodetect block. So what you see there is normal, unfortunately.
