Ok, so I finally bit the bullet and decided to get SSDs. I went with Kingston
SNV125-S2 drives, which use an Intel controller/34nm flash with 5 channels and
are 40gb. Right now I have two, but I plan on buying another two next month.
They don't currently have TRIM support, but it is planned (G2 Intel controller,
no TRIM supporting firmware yet).
I want to RAID-0 them, they have about 200mb/s read speed with large read
sizes. If use hardware RAID-0, I can never have TRIM - which I don't like. If
I use software RAID-0 will TRIM work properly?
I'm going to go out on a limb here and assume that the SB700 southbridge will
not support 800mb/s of bandwidth. Are there any PCI-E x1 v2.0 cards for SATA-II
that play well with Linux? I've only seen them listed as PCI-E x1 for SATA II.
I see that Highpoint now sells a 2 port PCI-E x1 v2.0 SATA-III card, which I
assume uses the Marvel controller. I couldn't really find any information about
people using it. Would two of these work well for an entirely software RAID-0
with 4 SSDs? Or am I stuck with buying a real controller (ie Adaptec 2 series)?
In fact, will the Intel 333 on the Adaptec PCI-E x4 card support that kind of
bandwidth? I don't really have any experience with hardware RAID or very high
bandwidth RAID at all. Any idea where I should start with stripe size?
