get a few VelociRaptor WD6000HLHX 600gb drives... ...

I would still prefer SSD's at that price....

I use VelociRaptor drives for all my media. Large amounts of quick space on the cheap, I bought them on sale + 15% on newegg coupon. On board RAID was quick with them, never benched though...

Not sure.... I only know of the Seagate XT drives...

They also have the hybrid revo drives with a 1tb or 2tb drive...

get a few Hybrid drives for space... run two raid0 arrays... 2x ssd's for main array and 2x hybrid drives for storage..

is there 3.5" hybrids? I only know of 2.5" 750GB not much bigger than 480GB SSD's and SSD's are always faster than hybrids right

I had one of the 120gb X2 versions a while ago... It was faster than my two Sata3 SSD's in raid...

I would go with 2 x 256gb SSD's in raid 0 using your onboard controller....

I have TB's of videos

Why not a couple OCZ revo drives if all your after is performance.

I'm a little wary of pci express drives especially transportability

plus the price tag

plus the confusion of whether the cheaper one would give me the performance worth the price compared to the one above:

EDIT: and mediocre reviews

How many disks do you have. Number of spindles matter a lot. If you only have 3 or 4 disks then you may not get much improvement. If you have 16 or 20 or 28 disks then high end cards can show amazing improvement in throughput. Spindles matter. 10TB array made up of 5x2TB disks is going to have less performance than 10TB array made up of 20x500MB disks.

SSD are making that less relevant though. Technically there is no reason why a 1TB SSD should be any slower than 2x500MB SSDs. In the real world limits on controllers, cache, etc mean that often 2x500MB in RAID ARE faster than a single 1TB SSD but that doesn't have to be true. Some high end enterprise SSD have massive amounts of cache and actually perform worse in RAID.

I've witnessed poor performance of 2xSSD's in RAID 0

thanks, but now I know you're a robot because you misused MB instead of GB every time

Depends on the controller.... I would guess it would be about the same...

OP

guy with that controller has the 2nd highest benchmark: http://ppbm5.com/DB-PPBM5-2.php

the highest claims "ram cache" is his secret...

by the looks of the results it seems a raid card matters a little more than having the best gpu or best cpu/overclock
