I am looking to uprade the HD on my computer I am looking at either 2 x 128GB Samsung 830 (about £70 on Amazon) or 2 x Intel 180GB 330 (£90 on dabs) or 1x 256 Samsumg 830 (£130 on amazon) I want around 256GB of storage for my apps and a few game installs. At the moment I only have sata 2 so I have been considering getting a Star Tech SATA controller card from Amazon (amazon.co.uk/StarTech-com-Port-SATA-Express-Controller/dp/B003GS8VA4/ref=cm_cr_pr_product_top) Will using the controller card (and therefore Sata3) make that much difference? The StarTech card can do RAID 0 so is it worth putting 2 drives into RAID? I know TRIM didn't work for RAID in the past but this seems to have changed now, if it doesn't work can I get garbage collection to work easily enough? Finally if the RAID0 option is doable which drives would be the best bet to put in RAID? Thanks for all your help!
