Notes
I had some problems with ASU losing count due to power outages.
The 09 value reported in the Intel tool box gives you the power on hours, but the counter starts from 894800 so you have to deduct that amount to get the power on hours. If you want to double check try smartmon tools and the command I gave earlier. You will need to deduct 6 hours from the value reported by device statistics to make allowance for the factory test period.
canthearu ,
Thank you for making this thread even more interesting by adding the Intel 520 Fingers crossed it amazes us all!
Maybe something interesting will happen to the 520! All I know is, running an SLC drive is worse than watching paint dry... I mean, it only takes 24 hours for paint to dry. I'm not sure it's possible to kill an SLC drive outside of firmware failures.
Really, when was the last time you heard an antecdote about someone wearing out an SLC drive?

Todays update:

Dragging out the old Tesla coil this time I hope.
What? No, I was gonna use a Taser... why? Is that bad??
@canthearu
I've never ever heard of A-Ram (where are you located in the world?) I've heard of another Hong Kong brand, ASA (that uses SF). And the Chronos Deluxe 60 obviously used 32nm Toshiba, but didn't fare all that well either.

Australia. A-RAM isn't a big brand here either, but one of the online stores here had stock of the sandforce 1 drives and was a bit cheaper then the OCZ drive, so I went with it.
The Chronos Deluxe 60 might not have faired that well at the end, but hell, it was quick getting there ..... much quicker then my Intel 520 is proving to be!

Well that makes sense. The Samsung 830 64GB was ripping off 11,000GB a day for a while. It's on hiatus for a while, but it should have some good times still ahead.
The Chronos Deluxe 60 is a beast, but suffers from the SF problem -- it's write speeds are nowhere near peak (for a couple reasons, but if you've ever seen a graph of SF writes you'll understand why). My CD60 was putting in 10,000GB a day host writes, but only 7300GB NAND writes. Hopefully I'll have some drives that beat the doors off it shortly. I got a new Vertex Turbo on the way (which won't be that fast), but who knows what surprises tomorrow may hold? I've been sitting on a few candidates for a while, but I can only run so many drives at once, and the Vertex Turbo and the MTRON (and the 64GB Samsung 830 eventually) are already gonna take up some spots in the endurance rig.

To be fair, I think people get a bit too upset about compressible vs incompressible performance. All 60gig drives are designed fairly cheap, to use as few chips as possible without utterly crippling the controller, so you shouldn't be expecting 256gig drive performance out of a 64gig drive. It doesn't help that virtually drive makers post extremely over the top sequential write values in their specs ... For example, my torqx 64gig manual says 230meg per second sequential writes ... fat chance, it does 18meg or so a second sustained and that is it.
It isn't really fair to criticise a sandforce drive for slow incompressible writes when it is paired with 64gig of Async NAND, As the Chronos Deluxe show, pair it up with some nice Toggle Mode NAND, and the sandforce controller can do incompressible about as well as any other drive.
That isn't to say the sandforce drives can't go faster when doing incompressible data .... would be nice to see a bit of a boost in this area when the sandforce 3 comes out
first of all, thanks for this thread. it's very interesting and informative!
...but just out of curiosity: do you guys really buy all these drives just to send them straight to hell? or do you get these for cheap from supporters/sponsors?
keep it up!

Unfortunately I have no-one to sponsor me, so I have to buy the drives myself.
There certainly is an opening if you are interested.
Edit: I don't view it as sending the drives to hell, although the troqx belongs there. I view it as a sacrifice in the process of learning how SSDs live and die. How can I preach the longevity of SSDs if it is never tested.

Yeah, I'd be happy to test anything a manufacturer wants to send me (but no one has taken me up on my offer), but like canthearu, I don't think of it as just sending a drive to Hell. You get to see all sorts of behavior you'd not otherwise ever get to see. And since it's usually easier to "get a result" on a less expensive, lower capacity drive, it lowers the barrier of entry. If you could only use 512GB drives there wouldn't be many SSDs in the test since A)they are expensive and B) it would take a long damn time. I was able to get some BNIB MTRONs pretty cheap for example, and if you shop around there are some really good deals.
It's not just an endurance test in the strictest sense, it's a variety of things all rolled into one.
EDIT
But yeah, canthearu, that Torqx suqx something fierce.
My Patriot with the 3016 suqx worse though:
