There are 2 possibilites to modify cache settings in the Adaptec Storage Manager. - Physical drive - Write-back or Write-through - Logical drive - Write-back, Write-back only with battery, write-through
I do have a battery, so I would set Write-back only with battery for logical drive. However, what should I set on the physical drive?
Is the write-back caching on physical drive provided by the controller backed by the battery as well - or is it provided by the drive and it should be switched to write-through? (I do not have a UPS yet). I have not found any clue in Adaptec documentation, the ASM Guide even does not mention the logical drive settings.
The adaptec model is 52445, but the settings seems to be quite generic in the Adaptec Storage Manager.
