I have 4 ssd that I want to put in a raid - 0 array for a video editing station. It's going to be the work drive and so is intended for fast read/write of rather large files, but smaller assets will also temporaily reside on the array (like pictures) to facilitate the editing process.
I have an older 9650se-4lpml 3ware card (before they were bought out by lsi!) that has worked great for hard drives. but time marches on and a new video station demands new hardware. That card has 4 sata2 ports at 3gb/s. (Retail is still >400 but would be willing to sell for less!)
I cannot decide which raid card will best be suited to 4 ssds. the ssds are micron micro ssd 128 gb

This is not a server so an 8 port card is not really necessary. Tom's says 3gb/s is not enough

so that means I need a 6 gb/s raid controller card. mobo is asus maximus gen5 which has 2 pcie3.0 slots. one will be for the display adapter. I am rather confused over the proliferation of raid cards. LSI's website lists megaraid, megaraid value and regular raid.

These are all pcie 2.0
And then there are host bus adapters which typically do not have hardware raid firmware-however, some can be flashed with firmware that enables raid function
(http://www.lsi.com/channel/products/storagecomponents/Pages/HBAs.aspx) There are few pcie 3.0 cards out but this one is LSI SAS 9207-8I PCIE 3.0,
Can someone help me understand the real differences? Since I am only looking for raid 0 I don't think the added expense of a real raid card with ram and processor would benefit.
the raid cards i have seen well regarded are: 9260-4i PCIE 2.0, 9750-4i but the pci3 3.0 card would seem to have higher throughput.
PS
wow. just read a thread about the sas 3008 that will be out next year - 12 gb/s! but I dont think my 4 ssds will ever be able to do that!
