Guys, you got more work coming :) We need someone to confirm that this new tech works:

Since I power cycled the 830 today, I did the update. 4 hours later, the PE cycle count is still the same. I can't tell you how irritating this is... I bet it takes 72 hours to start incrementing again.
WOW! congrats! I believe that was the impetus for this very thread :)
great to see it go the full year, has anyone ever went back and checked that Japanese website where they were testing their drive? i wonder if it is still going?
btw you guys are awesome, all that have offered up drives are real contributors, and that is reflected in the milliion+ views of this thread.
Truly one of the most epic threads ever :)
I forget to check for firmware updates on the Samsung.
I'm sure we'll get noticed when there is a new one.
Correcting 177 should be an easy fix, at least that's what one would think.

The Vertex 4 is getting close to 3K which is spec for the NAND. (according to some review sites)
A few weeks back, I tried to calculate how many PE cycles the V4's firmware associated with MWI. It looked as though the MWI was based on 7K PE cycles. Canthearu's V4 only had 100TB back then, so maybe I did something wrong. But the flash is only 3K rated.
Based on MWI it looks to aim for ~5K.
(~2700 cycles and 48% remaining)
Samsung 830 256GB Day 60

Well, MWI is going down a lot quicker for the V4 on 1.4RC.
Typical OCZ to cheap out on the NAND and not tell anyone.
So, if I'm reading the charts correctly, currently the highest endurance drives are Intel & Samsung?
Also, just to clarify, Anvil, does your utility do any crc checks of the data in the read cycle (i.e. will it catch any errors if the drive mis-writes or mis-reads them back to your application?) Basically seeing if we have the data here that would also help bound bit error expectations on the drives that are being tested.
The second chart shows estimated current PE cycle count for presently running drives (not the past drives). So far Intel, Crucial, and Samsung are doing the best, but then, 6 of the 8 are made by those three companies. And they each own fabs, so it shouldn't be that surprising.
Nope, the Torqx 2 is finished. While it did secure erase and I was able to push slightly more data to it ... windows event viewer is continually reporting write errors and ASU is unresponsive. I think it also crashed my endurance rig/HTPC last night.
My last status update is probably accurate enough for this drive. Add on 5TiB if you care.
Torqx 2 = dead and unloved :)
Like my MTRONS and Turbos and Octane, it too is an also-ran. The Phison needs some work.
The departure of the Torqx 2 was expected, not overly impressive.
I'm debating what to use as the next drive, the SF drives have been done almost to death and so I'm looking at something else.
There are some great offers on 128GB Petrol, Octane and m4, some of them have been done (Octane) and the m4 is currently being tested in 64GB capacity.
Late last night I started thinking about testing 3K drives, i.e. Intel 330 or the Kingston HyperX 3K, they are both interesting drives but then we are back on the SF controller...
(still got the Force 3 though, could do some other compression ratio testing...)
3K units are very interesting and the plextor m3/m3p would have been a good contestant. :)
