Hi,
Is BBU still needed with SSD?
SSD has its own cache. And in certain models such as Intel 320 that cache is backed by capacitors. So in a sense that cache acts as a BBU that's backed by capacitors instead of batteries.
In this case is BBU still needed? If I put 2 SSD in software RAID 1, would that be any slower than 2 SSD in HW RAID 1 with BBU? What are the pros and cons?
Thanks.
Andy
