The 320 can report another value for "wearout"
Look at post #799, could be that I've already been there as I've done a few extra tests on the 320 Series, will check when I get back home later tonight.

Too bad the Samsung and the Crucial have crippled SMART data. Intel is still the best at this point in time. Hoping they get their act together and develop their own 6gbps controller with 34nm NAND and best for 4K random read / write ( only few care about sequential ) !!!

Hi Vapor, any chance of showing the writes that have occurred following notification that the MWI is exhausted? Maybe a hatched extension on the bar in the MWI Exhaustion graph?
I'm surprised at how much the Samsung 470 has been able to write after MWI exhaustion. At this rate it will be able to double the amount of data it took to exhaust the MWI.
Is anyone else going to getting a SF2xxx drive to test? If not I might pick one up. One "hacked" and one with throttling enabled would be interesting.
I'll find out on mine as well, just need to get an opportunity to power down for a few minutes.

^ look in your PM.
I'll try to get a special build for you later today, in order to find that special SMART attribute for reporting wearout.
I've figured out the Host writes on the 320 series using totally undocumented vendor specific info returned by WMI.
--
149.40TB Host writes
MWI 18
Reallocated sectors : 6
MD5, all tests were OK.
@Vapor
A P/E count chart would be useful in general. (TiB written/capacity)

Hardware:
Is nobody going to take out my offer and start testing endurance in terms of secure erases. This is just like writing the whole capacity of the SSD in a couple of seconds as it "zaps" the SSD NAND cells and resets them to 0. Anyone interested so we can see how durable this mechanism is and how many times it can be secure erased before it fails ??? Maybe an automated hdparm script or something. Anyone ???
This really is a valid point that also needs to be tested if we are talking about SSD endurance.
Or maybe test it on the V2 drive so we can see how many secure erases it can take if the standard endurance test failed because of throttling etc. ???
^^
You need to repower the drive every time you do a secure erase. Nobody is going to sit there and do it.
That was the intention when I first made it, thanks for reminding me
Anvil, do you mean a bar chart with P/E cycles? Or a bar chart with normalized writes? Unfortunately, only the Crucials, the Samsung, and the SandForce show anything directly related to NAND writes (and therefore P/E cycles).
C300 update from earlier today, didn't have a chance to post.
29.971TiB, 90 MWI, 505 P/E cycles, 61.8MiB/s, ~240/0 MD5 runs/mismatches

No, I meant "Host writes" / Capacity, which can be used by all* drives and it should be pretty close to the P/E count for the Intels.
(all drives if using the running total option)
We will need something as the counters stops telling what's going on and that time has come for the 320, unless we find some way to get to the other wear-out counter, it would still leave the X25 series out in the cold as there is no extra wear-out counter.
It's not much but it's something.

Hardware:
110.000 TiB, 309 hours, sa177: 1/1/9123
The other two unknown SMART attributes, 178 and 235, are still at 72/72/276 and 99/99/2, just as they were when the SSD was fresh out of the box.
110 TiB comes to 66.2 GB per day for 5 years. So the Samsung 470 64GB SSD has passed the milestone where you could have written the entire available capacity of the SSD, 64GB, each and every day for 5 years.

198TB. 20 reallocated sectors. Md5 OK. Anvil - I will try your new app tonight to see if I can get that SMART attribute.
There was something wrong with xs last night so here are the numbers from yesterday evening:
273 hours, 80,1158 TiB, Wear Leveling Count and Percentage of the rated lifetime used has gone from 57 to 54.
Avg speed for all 273 hours is roughly is 85,47 MiB/s
This mornings numbers are:
283 hours, 83,1993 TiB, Wear Leveling Count and Percentage of the rated lifetime used has gone from 54 to 53.
Avg speed for all 283 hours is roughly is 85,63 MiB/s
