Does hp raid controller really use ram cache for ssds?

[mgiammarco]

Hello,
in a 440ar controller I have built a raid1 with sas disks and several raido0 with ssd disks.

I then disabled ssd smartcache and added controller cache.

SAS disk performance improved greatly using controller cache.

SSD improved nothing. I suspect the controller does not use its ram cache when the disk is ssd.

Or is it possible that with raid0 no ram cache is used?

Thanks,

Mario

RAID 0 does not require cahce for performance. SSD itself is a flash technology which is better than SAS drives.

Thank you
