It does to me, because some controllers are known to cause problems, like many of Sandforce's controllers causing BSOD issues with certain firmwares.
Intel released a series of drives based on the same controller. Very solid from what I've heard.
I also use the same controller but hearing about the potential issues, have been careful in what firmware I have applied to them. Been running 2x Vertex 3 drives for quite some time now and had 1 issue from either drive
ever. Firmware update solved the problem must be almost 12 months ago. No reformatting required.
OCZ might have released some iffy firmware but they brought to light some bad SATA 3 implementations by diving in the deep end so early. Intel were culpable there and the issues were not limited to SandForce.
You want to stay away from dodgy chipsets, why don't you stay away from Intel motherboard platforms? No TRIM on RAID unless you are on Z77. They keep stuffing it up. Their integrated graphics have legendary incompetence. Only recently people were getting replacement boards because the SATA 2 was stuffed on one chipset?
Oh ever wondered why LGA2011 (and possibly LGA1155?) came out with 2x SATA 3 ports when the initial roadmaps had 6 ports planned? Good ol' Intel...
Marvell SATA 3 controllers? Rubbish. Bandwidth starved - writes are worse than a SATA 2 controller. Missing TRIM on RAID of course. Don't know if they even support TRIM fullstop?
Then there's Microsoft. Want to run TRIM on RAID on a SCSI controller card? You can't on Win7. Win7 simply does not support passing TRIM to a SCSI controller. Maybe on Win8?
Relatively speaking, SandForce 2 controllers look pretty good to me.
EDIT: I will say, I'm a bit disturbed about the return rate figures. Curious to work out why the figures are so high for OCZ. They used to have a policy in the forums of pushing everyone to update firmware the moment a new one came out without a real settling period to see if there were problems.
