I have Pegasus3 r4 16tb with 4 Toshiba MD04ACA4 SATA HDD.  Do not know whether they are 128 or 256. Not able to find Toshiba replacement to have for "just in case" a disc fails. What replacement disc would be best? I am currently looking at WD4005FZBX WD Black 4TB performance Desktop HDD 7200 RPM SATA 6 Gb/s 256MB cache 3.5 inch.  Would this work? Any suggestions?

Hi Andrew,

Pegasus 3 units have 3 years warranty from the date of purchase . If this unit is under warranty, please open a case at with the latest report. We will advise you on next step.

Steps to save the subsystem report :

2) Click subsystem information icon on the top of the window.

3) Click the lock symbol on the left bottom corner of the screen to unlock the utility.

4) Click on save service report button to save the subsystem report and attach it to the case.

If not under warranty, refer to the below link and download the compatibility list. Any drives in the list would work.

Thanks !
