This is getting interesting as they pass the rated wearout indicator limit.

Now 5 SSDs participating, and rumors of more joining soon.

I want to see when they actually start failing, I think it will be quite some time from now.

I agree. By the MWI the 320 is dead. It just has not realized it. Kind of like the old commercial about the timex watch. Takes a licking but keeps on ticking.

Obviously Hoppy took the day off so here are the ststs as of today from xtremesystems

Writes graph is a good idea to post. It shows all of them.

Hoppy will post the Intels tomorrow. I'm updating them every other day.

Getting lazy I see.

Hoppy, what is amazing to me is the Samsung. Look where it is in writes. The Intels were running for 3 weeks before the Samsung even started. It's writing faster than the 2 intels combined. It's a shame it can't read that fast.

Hopalong X · Jul 13, 2011

We need an Intel read and a Samsung write. Perfection!

I've been playing with a graph for the Extreme Systems SSD Write Endurance 25nm Vs 34nm thread.

Extreme Systems SSD Endurance testing Graph 14July11.PNG

The black bar is the manufacturer's rated write exhaustion.
Number in the bar graph is the current number of writes.

Samsung has low expectations huh?

Johnw, who is runnng the Samsung , made the statement that the Samsung could write half of it's capacity (32GB) every day for the next 5 years. It hinmk the 320 is writing around 40MB/s and the X25-V about 30 MB/s, and the Samsung is areoun 140MB/s. The Samsung is catching up quickly. Too bad it's read scotes are not as good. I read up om it at NEwegg. Most there are quite happy with it and are getting WEI scoues of 7.5 and 7.6. that part I don't understand.

Very low, must be afraid of failures and RMA's, they will use any excuse they can even self fabricated ones.

essenbe · Jul 14, 2011

I think all manufacturers low ball their expectations. Better to understate it than overstate. Look at Intel.

Dave76 · Jul 14, 2011

They all are definitely low on the life expectancy of SSDs.
I expect to see a x4 on most of them, might be a little optimistic.

The Samsung is 1/3 of the next closest one on the XS SSD thread.

In TiB
59.5 - Samsung 470
177.5 - Crucial M4
182.3 - Intel X25-V
190.0 - Intel 320
216.0 - OCZ V2
306.1 - Crucial C300

I know, but in reality if the Samsung only lasted 59.5 that would be OK by me. I won't write 59TB in my lifetime, nor will most people. I'm just curious how they rate the drives. It is really a PR thing I think. The warranty is for a period of time not writes as far as I am aware.

Here's my Intel X-25M g2 80gb
First picture is when I got it cca 6 months ago and second is from yesterday.
Very similar to wine, as older it get's, better it is

P.S. Same OS

Good job. I have one too and it seems to be doing about the same as when I first got it. I just don't run too many tests on it.

sizif · Jul 14, 2011

Neither do I, few times at all. First picture is actualy my first test on it and second pic is maybe, 3rd or 4th at all.
I like results in practice more then in bench. Disk is about 30% empty, that space is for photoshop, premiere and similar software caching

Here is more proof of your suspicion of understatement of SSD endurance.

Intel X25-V measured durability

Intel X25-V 40GB.

Written 782.9TB, equivalent to about 21569 times, including random write 21TB.

The translation is not very clear but, seems that a power failure, assuming electrical power to the building, caused the controller firmware to crash.
Tested for 300 days.

This is approximately 4.3 times the Intel published life expectancy.
The failure was not due to the SSD itself, so it would have gone further.

It would be nearly impossible for me to write that much to my X25-V, even trying to do so ....

Im actually surprised how long they are lasting. I always thought limiting writes was a bit over-hyped but i didnt expect that much out of them.

I agree. I am surprised they have written this much - and they are still going! I wouldn't care if they only wrote 1/3 of that. I couldn't possibly write that much.
