The G1 is now very close to 1% spare area. Just hope I get home in time....:)
So, the samsung 830 seems to go on and on, it just won't give up! I am considering upgrading to a SSD and seeing the 830 withstand the torture like that... I think I know what I'll buy.

Hey, I need an SSD for the server/WS that I am building. I only need 60GB at most, I do intend to manually over provision between 20-30%, perhaps 50% for the heck of it if the drive is 200GB+
My budget is 300$, I want this SSD to last as long as possible. If it doesn't last 10 years It's garbage for me. At the same time, I don't want to be spending useless $$. If a simple intel 520 120GB SSD will do, that's nice. but if a 256GB 520 or samsung 830 or Crucial M4 would be significantly better, why not. What would you recommend?

I did see that, it looks awesome :) In Canada this SSD is rare, I did find it at 200$ + S/H and tax so 240$. So this is the best bang/$ for extreme longevity? I know M4s are dirt cheap I see the 64GB one doing well, I've seen the 512GB around 350$ etc. Out of curiosity how do the 128/256/512 M4s do?Quote:

Speed a bit low because I was gaming on the HTPC yesterday. It has slowly been recovering.
ok I am not doing the endurance test but thought I would post 2 things here that stand out on my 830.
it has crc errors, I noticed christopher's has 0 even after all his endurance testing. mine has a raw value of 82.
also I have a non 0 value for POR recovery count which is D.
Seems ssd life pro cant predict life left due to missing values.
My 830's CRC Error count is actually 2. It's actually a SATA error count. Mine increased when another drive I was testing died.
I've caused my Vertex 4 to completely lockup (but not kill it, secure erase saves it) via using ASU over a couple of days:
http://www.ocztechnologyforum.com/fo...l=1#post750877
The drive not only slowed down while performing a full surface wipe, but it also locked the drive up, indicating some kind of resource leak in the OCZ firmware that isn't cleaned up during heavy writes. If OCZ fix this, I will continue endurance testing, but until then, the V4 is suspended.
So because your drive showed this behaviour we have a FW issue?
1 drive with this behaviour means 1million are bad? No one else has complained about this...just you
if you used the drive normally as an end user does did it show an issue?
If the drive needed a secure erase, I guess all the data was lost. And when data is lost, the drive is called unreliable. If indeed it is a firmware bug, then yes, 1 million SSDs are bad until the bug is fixed.
Unless my drive is faulty, you do have a firmware issue, whether you want to believe it or not, and whether you fix it or not. I should not be able to be able to induce a complete lockup in an SSD no matter what sequence and timing of LBA writes I perform. I gave the drive ample time to recover before I ran the final write pass that locked up, so this issue is accumulative and not self correcting. Since you haven't said that you cannot reproduce my results I'll assume it is not just my drive.Quote:

As for low write load desktop end users, sure, of course they won't notice this issue any time soon. Firmware 1.5 has only been out a couple of months. However, this kind of accelerated stress testing can show what a user will see in months/years of use.
Stress testing like what I did should really be part of your standard firmware testing. Don't peddle crap about usage models to cover for not running the hard yards in validation.
request an RMA...
I have run a 256GiB Vtx4 on 1.5 continually for days/weeks stress testing 100% of the drive, it got HOT, it kept going and its now sat in my macbook pro.
Vtx4's can run warm, you may have just heated that drive up and it took a dump...
Seriously though, 1 guy with an issue making it sound like the whole FW is broken...you really do need to see the big picture, I ONLY act and report issues when I see there is an issue...if we all jumped when 1 guy reports his drive took a dump you would never get beta FW never mind final
I will say this 1 last time...the VTX4 is designed to deliver fast writes BUT you have to let the drive FW work as intended, this means there is a possibility to push the drive outside of how it was designed to work....BUT end users who just use the drives never do this. In most cases the drive will just crawl...in your case something else happened but its never happened to me or any of the beta testers and not at HQ where we have been testing Vtx4 continually for months now continually.
We do NOT have a FW issue...you just think we do, if we did I would have a forum full of people with the same exact issue...and I don't, and neither does inhouse support...please see there is a massive machine watching and they jump ONLY when there is something to jump for.
If you want an RMA please PM Ryder on the ocz forum....and please stop wearing out your drive needlessly, we do not warrant nand burn remember, no one does
Some off topic: I am working as a software developer and I believe I have heard the "it's client fault" story tens, maybe hundreds of times and mostly from my boss, even when the problems were real.
Now Tony, you said something about "heat" and "dump". Are there any heat related issues with Vertex 4 series that we should know? Is it less tolerant to heat compared to Vertex 2 & 3? If yes, then does it have any heat protection (speed throttle, etc) ? Or any particular scenarios when it takes a dump?
I am watching with high interest the Vertex 4 endurance, however now it seems totally disappointing compared to Samsung 830.

Besides, I have never asked for a RMA on a drive with worn out NAND. However I did appreciate being offered a possible RMA on the previous drive I tested and do feel that the RMA processes of OCZ are among the smoothest.

I've been out of town, so I've haven't had the chance to post any updates lately, but TBH not much has happened... just a lot more writes. We're getting close to the 4 million GiB mark though.
'Twill be a momentous occasion. But then again, the M4 is at almost 1.5 PiB.
You didn't know but this Samsung is in fact a demigod, it can throw the data you send to him to the heavens so he's not hurt :P
Haven't checked on this thread in a long while. That M4 is just insane, 1.5BB on a 64GB drive is just ridiculous. http://smiliesftw.com/x/eek5boink.gif
Almost 4PB....that's damn impressive. Would love to see more 256GB drives get put to the test. It'd also be interesting to see how the 128GB 830 fairs to see just how much of an advantage the increased nand amount actually yields...or close to it maybe.
The M4 and the 830 are the 6gbps drives you want if you like writing a lot of data. Interestingly, the 64GB M4 and the 256GB 830 are about identical in terms of avg speed/capacity. Coincidence? Perhaps, but I don't think you'd have an issue getting 1.5PB on a 64GB 830 either.
Yes, Coincidence. They're just well built drives, I doubt Samsung and Micron would be sharing anything with each other.
No, I mean, if the 830 is 4x larger and 4x faster than the m4, perhaps they have equal amounts of recovery time and this is a large part of their success. It could just be their proprietary nand management techniques. It could be lots of things, but if you own a fab and have a proprietary controller (the M4's Marvell is pretty much their own controller in the end), you should be able to make a drive that lasts a long, long time.Quote:

The G1 decided that it had some more spare area hidden so the counter went from 0 to 59 and started to count down again. Very strange behaviour.
The m4 just keeps going and going and going.... Not much change just a little more cumulative corrected ecc.
What does concern me is the number of bad sectors on that SLC drive ....
That suprised me too. It burns through sectors at the same rate the G1 did in the begining.
Agreed.Quote:

I'm starting to get the feeling that this 830 might not ever die. Perhaps there is a critical point of wear beyond which the drive starts degrading rapidly? I can only hope.
Maybe it is the error correction that makes the difference. Drives with weak error correction implementation will show a gradual increase of bad sectors, just like Intel G1 while those with a strong one will have a fast degradation at the end. Probably the lack of a complex ECC in X25-E 64GB (at least not as complex as in the MLC drives) is forcing it to mark bad blocks faster.

The write speed has dropped to around 1 MiB/s on the G1. I think it's not long until it is finished. ASU is still slow and unresponsive but the drive still works and read speed is good.

The G1 has stabilized at 1 MiB/s but still hangs in there. Just have to wait and see what happens this week. Another development. The m4 has reportet its first raw read error rate. The last time it got these at 600TiB but still no reallocated sectors. :D
Hi guys :)
I've been out of town for a few weeks, my drives are OK but have been idle for some time, I'll get them restarted tomorrow.
I'll catch up the next few days.

At 08:42 this morning the G1 pulled his last breath and went away silently. It just couldn't take any more after 10.5 months of torture. I tried every trick in the book but I can't get it to connect again.
R.I.P Intel X25-M G1 80GB :(
My plans now is to update the firmware of my Mtron and Vertex 1 and throw them back in the blender :D
That G1 went out like a boss. 10.5 months of no TRIM is hardly a small victory. In reality, it must have written 5x that much internally. If it had TRIM.......

Yeah, the G1 went pretty well :)
I just did 24h retention test on sandisk ... didn't worry it at all.
I'm sure the Sammy 830 has passed the 4PB mark by now...hats off to Samsung for one solid and steady controller and to Chris for puttin' the screws to it in the quest(s) to see which drives go above and (waaay) beyond expectations. Altho the controller does have a lot of nand to work with vs other drives tested...I'm betting the 128GB and 64GB do just as well with respect to those drive sizes. Getting 2PB out of a 64GB Sammy wouldn't be a huge shocker, tho it'd be damn impressive.

I am surprised that such a drive can cost so competitively, could it even match SLC ?
what the ... ultra durable toughness drive like X25-V!
830's NAND is truly Toggle MLC.

May I dare dream of having a drive reach 1 PiB (well, without having to do something dumb like breaking out an Intel 510 or something!)
Since it came up, the 830 is using 27nm Samsung 1.0 Toggle. But IMHO the M4 getting 1.5PiB at 64GB is far more impressive... But it's only a matter of time before the 830 gets there.
Now you know how I felt. Finally, I just said "to hell with the dumb stuff," and got a 256GB 830.Quote:

The failure of each flash chip is statistically independent, which means it's more difficult to get a large drive with good quality flash chips together, than to get a small drive. Think of the cost of display/monitor - the price does not grow linearly with respect to area, but grows exponentially!Quote:

Just wanted to comment that this thread made me go run out and grab an 830 for my notebook. It's performing well, even on my ancient 2011 SATA II hardware. My only complaint is that it gets the palm area where the drive resides considerably warmer than before. I was writing 150GB or so to the drive at 200+MB/s, but I never noticed that area get that warm before.

The 830 gets warm; under prolonged writing mine stays around 52c, and it's in open air. The 830 is great for laptops since it only draws .38w at idle -- though load consumption is as much a
6w for the larger capacities.

The drive is undetected in bios. Tried it from 3 different machines. The G1 is truly dead.

The 830's instantaneous estimated speed is 350MB/s for most of the loop! If it weren't for the average being almost 1500 hours, avg/MBs would most likely be quite high.
350 MiB/s write speed after 4 PiB is ridiculous fast and impressive. :)

It maintains 340 to 350 for most loops now, which makes me concerned that it's getting faster. I remember 340 being the upper ceiling a few months back.Quote:

My 256GB under test runs between 50c and 54c. The 512GB is slightly slower in some places, slightly faster In others compared to the 256GB. They share the same number of dice, but the 512GB uses 64Gbit dice while the rest use 32gbit dies. I haven't run the 512GB for any length of time under endurance testing though.
