Subject: RAID 1 using SSD and 2 HDD
Date: Tue, 19 Jul 2011 11:15:22 -0700 [thread overview]
Message-ID: <4E25C9BA.1060401@dodtsair.com> (raw)
Is it possible to implement a RAID 1 array using two equal size HDD and
one smaller and faster SSD. The idea being that the resulting RAID
would have the same size of the HDD while picking up the speed benefits
of the SSD. You can do something similar today by just buying two
hybrid drives and putting them in an array. By purchasing a dedicated
SSD drive for that purpose you gain the ability of controlling the size
of the SSD portion. I was hoping the RAID array could use the SSD more
as a cache then a redundant storage.
