@ 64GB and 128GB sizes they are top performers and very reliable, especially with product support by Crucial.
What I wanted to know is between Samsung's, Marvell and Sandforce 2281/2200 series which is better and has the better performance and reliability? It seems from a lot of my reading and looking at reviews, the Sandforce based drives seem to have some issues with BSOD, freezing, and the whole firmware update issue. Now in my 15+ years of IT I know some people don't follow instructions, (and can really screw things up themselves lol) those things do happen.
Reliability hands down goes to Marvell and Samsung controllers. SandForce drives atm, not so much. It isn't just people doing things wrong with the SandForce drives, it is just that most of them just plain suck due to bugs in the firmware. Out of the 17 I have had experience with only 6 were fine. 11 of them I RMA'd for a different non-SandForce drive. The Intel 520 is the only exception, especially since they spent a whole extra year on developing their own modified SandForce firmware for it. Though SandFroce drives are good when they work. And with teh kinda recent take over by LSI there is always something to look forward to.
When I look at speed claims, it looked as though the Corsair GT had the faster read/write times, just wanted to make sure I am looking at the numbers correctly and wanted to get a "real" performance insight, as claimed numbers do differ from actual.
I usually go my AS SSD benchmark because it uses non-compressible data, so it stresses the hardest on SSDs, especially the SandForce drives because the controller does real time compression and can not compress the data. And by AS SSD @ 256GB the Plextor M3 wins followed by the Corsair Performance Pro then the intel 520 and Samsung 830. Then the M4, force GT, etc. But you will not notice a difference b/w any of them in real life usage. Honestly it is even hard to notice the difference b/w SSDs in RAID 0 vs a single one and a SSD on SATA 6Gb/s vs SATA 3Gb/s. lol
I suggest you start by reliability and product support -> capacity -> price -> speeds.
Intel and Samsung are the top names in the enterprise world, they have a record of great support and reliability.
Below that would be Crucial, Corsair, Plextor, etc in the consumer world.
BTW, I have an Asus P8/Z68 board with the Marvell and Intel 6GB/s SATA ports. Not sure if a difference is made from using either.
Do not use the Marvell SATA controller, the mobo ones are crap and limited on bandwidth. lol.
Which of the Sandforce controllers are better of the two, just wondered?
Sandforce 2281/2200 series?
It is the same controller. The 2200 series includes the 2281 and 2282 controller, etc.

drive. Same sandforce controller as a couple of the ones you listed and at $239 for 240GB, its under the magic $1/GB
edit: Sequential read/writes are not all that important. Anandtech is a good place to look for SSD reviews, he generally does a good job of explaining what is important
And this^ is very tempting lol.
