I'm building a fairly aggressive machine for both a backup host for
virtual machines and spare time development platform, compile engine and
testbed both. I want to get cost effective use from an SSD unit, and I
propose to use a 32GB unit as follows: for the root filesystem, 12GB,
which should hold all the usual root things, and 16GB for swap (12GB
RAM, and I want boot and/or hibernate to happen NOW). The remaining
space I think might be used for various high impact things, and one of
those with speeding raid.
If I were to create a small raid device, raid1, made of the 4GB Ssd and
4GB of SATA space, if I made the SATA write-mostly and write-behind, and
put the journal for my raid arrays (and bitmaps?) that seems likely to
provide a significant performance gain in small storage.
Am I missing anything here? Is there an obvious drawback I'm missing?
