My System Specs

Default

None of my drives are ever pushed over 60% full so that is not the case and I don't constantly write to them either. My OS drive and my games drive have had corrupt data on many different occasions, not just the games drive. I am running windows 7 and I have used ever recommended procedure for using SSDs (disabling indexing & defrag, moving page file to HDD, using only MS chipset drivers, etc.). My power is clean (UPS between the Corsair HX620 and my mains) and I am using high quality sata cables. I have had issues on three different motherboards as well (so it is not a chipset issue). I know I am in the minority but I find they are just to delicate to trust with critical use/data. As I said, the only SSD I have that hasn't had issue was the one in my HTPC that is by it's self and is only used to boot into windows 7 (so the page file and My documents, temps files are all on the SSD as well). Hell, I don't even run benchmarks anymore since I am worried I will get data corruption.

Oh, I have tried Freespace cleaner/FF as well. I stopped using it since I am scared to push my SSDs at this point.

What you are doing is basically a big hammer version of ITGC...and is even harder on the cells then the typical controller level ITGC. Basically while it is called "Tony Trim" its more like Tony ITGC. As the first part consildates data (thus using writes) and then the FSC /w FF option does even more writes.

In a nutshell you are writing and then rewriting to cells every time you do that 1-2 punch and using up more cells in the process. It is all you can do where you run raid....but this is one of the reasons I dont like raid ing SSDs and hardly recommend it to anyone.
Basically on avg for all ssds from less harsh to most (with trim being the best, lowest cell usage solution):
TRIM > ITGC > FreeSpace cleaner > Tony TRIM. (though the dif between T Trim and FSC is small, neither are really a good idea on modern SSDs unless you have no other choice).
After this insight from here I decided to break my Raid-0 so Trim can work properly. I'll use the other drive for a book end

Thanks

Well I have several SSD's in the house and non of them have failed. All have been running at full speed. My dad even has his business computer all on just a SSD. If you are worried about loosing info it is called a back-up. Everyone should have one and if you are REALLY concerned then there are off site back-ups like Carbonite. I love Carbonite.

Anyways there must be something else wrong.

love all my ssd's and i have only had to RMA 1 in the whole time i have been buying them, maybe i am lucky but i don't think so. Have purchased over 50 as of last week for clients .

It's too bad that Trim is not supported in Raid...so I've opted out of Raid. Not sure what to do with it now...maybe install Ubuntu Linux.

Almost all deaths I've seen including mine have been from controller deaths. Not from the NAND dying. So we will see how long they actually last.

I totally agree with this statement. One of my SSDs that I RMAed was caused by the firmware becoming randomly corrupt. This was an SSD that I had never flashed and there were no flashing tools available so it wasn't something I did either.

I agree that it usually is the controller (e.g. like with HDDs, dirty power nukes the controller), but I think that some care and feeding is still needed for the NAND. IMHO all the estimates Ive seen have been either extremely pessimistic (no free space) or happy happy joy joy (100% free space) ones on their lifespan. I know on my quick n dirty estimates say my drives (based on avg cell usage and 10K...wish ALL companies would allow that an not just Indilinx) says my MLC's will last about 20 years. BUT I always leave lots of room for wear leveling. This is actually one area where I LIKE how OCZ and now SandForce do things. IMHO Over-provisioning should be standard on ALL SSDs. That way you could fill them to 100% capacity and STILL have some room for wear-leveling AND cells for reallocation as older ones come up to their max usage. I prefer setting aside more then 4,8 or 6gb BUT something is better then nothing for peeps who DONT know to not over fill the drives. :)
