B.A.T.
Am I imagining things, or did the M4 go from 33 erase fail and 0 program fail to 33 erase and 26 program failures like 4 days ago? Hmm. I wonder if that just means it just had to try a couple times to erase or program, but no blocks were taken out of service.
You have good eyes. I missed that one. It changed to 26 between 29th and 30th of may.
Just for amusement (and with no expense spared) a 4 GB unbranded USB drive. No SMART info. :D
Assuming 1,000 P/E cycles @ 2.5 MB/s it could in theory last 19 days.

A01,
Do you happen to know what manner of flash is up in there? I'm sure when it dies you can pry it open. All things considered, 2.5 Mbs isn't terrible. It's not much worse than the 32GB PS 100 Phison I tried.

Stupid question perhaps but here goes anyway;
Looking at the charts in post 1 can I assume that if a given 60Gig drive reaches MWI in xTB written then the `120Gig version of the same drive should hit MWI in 2xTB and the 240 in 4xTB etc?
This is mostly true for most drives. Most drives use average PE cycle count to determine MWI 1, meaning a drive with flash rated for 5K PE cycles will consume 1 percent of MWI every 50 PE cycles. The 64GB Turbo I ran used 1 PE cycle for every 56GB written, so for every 2800 GiB written in the test the drive would reduce MWI by 1.Quote:

So after 7 days I put the drives back in the endurance rig. Both drives' average speed is down by 5MB/s, and current speeds never quite get as high. Even with all power saving technologies disabled and on the same RST version, it's just not as fast. Almost, but not quite.
same MB or different?
Different. All other things being equal, different MBs have slightly different performance (even on 1155).Quote:

As competition to Anvil's Intel 330, I present the Sandisk Extreme G25 - 120gig.
Sporting 128gig of 24nm Toggle NAND and the sandforce controller, Sandisk has created a little ripper of a drive at a very competitive price. Unfortunately, due to the nature of the sandforce controller, and the configuration of NAND in this drive, speed will be a little bit slower then the Intel 330. However, it is also a bit cheaper, and can be gotten in larger sizes then the intel 330.

Attachment 127370
Notes: I does appear that the sandforce controller can manage bad blocks .... loading the initial data on the drive caused a couple of bad blocks to appear. This drive must have escaped the factory before it's bad blocks where fully found.
Edit: I am using same specs as other drives, but have 64gig of static data to match Anvil's 330.
The Sandisk Extreme should be very interesting vs the 330
I had expected the Extreme to be a bit faster than the Intel, having said that, I'm positively surprised by the performance of the 330.
Corsair Neutron could be the next one to test, scheduled to be available in July. (new controller)
Well, the Intel 330 isn't using RAISE, so the sandisk extreme g25 has to work harder during writes ... that said, I'm getting about 120meg per sec speed, so it isn't a lot slower.Quote:

That's true, otoh the 330 is said to be using 6 channels. (6 out of 8)Quote:

The 330 is using all 8 channels on the 60/120s.
I suppose it's possible be that the 180GB is only using 6 channels with 4 way interleaving, but the 180GB 330 is also different in that it's using "redundancy" (ie Intel RAISE), not found on the other models.
All in all, the 330 is pretty excellent IMHO, I'm curious to see if the 120GB happens to last forever too.

3 days left to 1 PiB :)
But after the Mtron started both my Intel drives have dropped their writespeed. Looks like my endurance rig is taking a beating at the moment :D
I've got a few unboxed 520's 120GB, I'll compare it to the 330, if they don't compare it could still be down to different firmwares.Quote:

@B.A.T
3rd drive to get past 1PB, not bad :)
4 drives doesn't leave much room for other than testing (I expect it's doing nothing but testing), with that combination of drives it's probably what your rig can take.
7 months of writing and finally I'm at 1 PB. 1 PiB in another 3 days. This m4 has behaved differently than the first. It could either be the upgraded fw or quality of the nand but this one has less reported error than the first and the wa is also lower. The first had 1.06 and this is around 1,004
It's a dedicated rig placed in my basement so it doesn't need to do much else :)
4 test drives + a boot device is a lot for one rig to handle. If I start testing some more drives, I'll have to figure out an alternate hardware arrangement.
The M3P and 830 don't seem to be butting heads, but they are slightly slower in the dedicated enterprise rig.
that's cuz they are A#1 DrivesQuote:

Not having more than 2x 6Gbs ports is a real pain.
My AMD rig (CHIV) developed some instability that I never was able to fix, I'll have to consider where to start making changes.
On the 330 vs 520 thing, I wasn't able to test the 520 on the same platform where the 330 was tested (it's now running W8) but from what I can see, performance is in favor of the 520, by a small margin.
I tried testing the 330 but wasn't able to get it back to FOB speed by normal means and I won't secure erase it during testing.
I might do an experiment at some point to see if performance can be restored to FOB state.

I've been thinking of that exact drive as I need the space (and they are currently discounted)
What's up with 4K writes at QD1? (a re-run might show normal figures)
Sequentials are looking good.
No, didn't change a bit. 480GB SSD are slower from the spec. I don't really care, it's fast enough for me. This SSD is used for games and storage, sequential speed is the most important for me in this case.Quote:

The Sandisk has not had any further reallocations from the last 24 hours. I wonder when the media wear indicator is going to start moving? Also, the Power-on hours normalized value went from 100 to 0 in 24 hours ... so I think write throttling won't be a problem on this drive, unlike the silicon power drive from before.

I wonder about the Samsung, it just looks to go on and on and...
I looked at the 64GB drive (which was not exactly dead but still out of the contest) and you are way past what one could expect by just scaling up the figures from the 64GB drive.
415iTB and "P/E" (Host writes / Capacity) ended at ~7130 is the latest recording I've got and that would translate to 1660TiB, you are already +210TiB .
Attachment 127401
Anvil,
The 64GB 830 was subject to crazy high WA due to 01FW. When I put 02FW on it, WA went back to normal. Since the 256GB is on 03FW, the numbers aren't really comparable.
The 256GB is using 1 avg PE cycle for every 230GB written, the 64GB was using 1 for every 16GB or so for the first two weeks of testing until I put 02FW on it. After that it was 1 for every 58GB or so. I'd have to go back and look.
Attachment 127403Attachment 127404
When I stopped testing of the 64GB it had over 16,000PE cycles on it.
Generic USB Drive – 4 GB
Writes: 620.11 GB

Write speed has increased from 2.45 MB/s to 2.71 MB/s from start to current. Seems that write speeds increase as the NAND “wears in.”
btw 19 nm Toshiba Toggle Nands with Sandforce Controller
http://thessdreview.com/latest-buzz/...x-2012-update/
19nm toggle nands should be Toggle Mode 2.0 right? 400MT/s or these are still ver 1.0 200MT/s just like 24nm Type B T-Nands?
Assuming a WAF of 1.10, the M3P has used 2184 PE cycles. It's doing about 957.34 GiB an hour, or around 8.3 PE cycles per hour.
To date, the 830 has 1,933,004 GiB in LBA writes (8338 Wear Leveling Count). 1,933,004 / 8338 WLC = 231.83GiB per WLC. Since the LBA writes are about 12TB ahead of ASU, dividing WLC by ASU's figure equals about 230GiB/WLC. This number has been consistent throughout the first 79 days of testing. The 830 is using >4 PE cycles per hour, or 105 to 110 per day.
EDIT
I timed it, and in 7 hours the 830 used 30 PE cycles, about 4.28 an hour. Sometimes the drive is faster, sometimes slower, and I'm not sure if the slower periods are using more or less PE cycles. You really have to average it out over 7 days or so.

Generic USB Drive – 4 GB
Writes: 889.80 GB
Average speed: 2.72 MB/s
Going to have to suspend for a week as I'm going to be traveling.
The USB Drive is a bit interesting, as is SD/CF cards for DSLRs, they do take some beating.
I've been using a 32GB SanDisk Cruzer? for years, still working but is noticeably slower than it used to be, large files are OK but small files are taking forever.
Not sure how much is written but it was used on a daily basis and a few times a week for "backup" of a single ~2GB file, I have tried and there is no way of restoring performance.
A USB thumb drive does not have a controller (AFAIK), so it’s about as close as you can get to testing NAND only without specialist equipment. I was interested to see how well the NAND stacked up with no controller vs a sophisticated SSD controller. TBH I knew I was going to be travelling, but I didn’t think it would have lasted until then. It’s a bit annoying to have to stop, but theoretically it should be well within P/E cycles, so hopefully no big deal.
Ummm, no, USB thumb drives certainly have controllers. They perform wear leveling and command multiplexing like destop drives. Most won't be as complicated nor as advanced as the sandforce and marvell SSD controllers, but the basic functionality is there.
USB/CF/SD:SSD :: WW I Biplane:F22 Raptor
Some mobile devices have a couple of flash ICs that are managed and operated by the SoC as I understand it, while others have discreet flash controllers.
I beg to differ. SD/CF controllers sure, they are as simple as they get. But USB drive controllers are more complex, especially with the advent of extremely large USB 3.0 drives. More akin to a P51 Mustang in your analogy.Quote:

That's quite true. Many USB 3.0 devices really blur the line, I was more referring to "old-style" USB drives. There are quite a few in-between solutions and some are more SSDs (or are SSDs). But that USB stick I've had floating around for the past 6 years? Probably not that bright.Quote:

Most Crucial's are already flagged with Bad Blocks, found in the "Factory Bad Blocks" SMART attribute.
So, there are some bad blocks, I don't think I've got a single Crucial w/o some blocks flagged. (this should be adapted by all vendors)
Very few drives actually show the factory bad block count. Indilinx on Cognac firmware and the Microns/Crucials are the lone drives which do (that I can think of off the top of my head).
I think some of the keys to success are successfully identifying questionable blocks during manufacturing. But it's fairly impressive that so many drives are making it past MWI before flagging bad blocks at "runtime"
I've probably mentioned that some of the G2's had bad blocks right from the start. (X25-V's in particular)

The m4 is ahead of the X25-V, it made it just in time for 1PiB :)

Bravo! Think about all the drives which never made it this far... The list is long. And now we have two drives past 1PiB and one closing in on 2PiB.
It's been a bumpy ride, that's for sure :)
I hope the G1 also makes it to 1 PiB. 300TiB left and it's strugling some.
Time for a retention test on that m4 *mwhahahaha*
But grats on the 1PB ... I didn't think the m4 could make it.
The 256GB 830 is 4x the capacity of the 64GB M4, and does 4x the M4's average speed. Of course, the M3P is 2x the capacity and almost 4x the M4's average speed, so at this point, I'd say the Crucial with 18K PE cycles on it will still probably outlive the M3P.
Thank you! :)Quote:

Have you calculated the WA on those drives? The m4 got at the moment a very low WA and I think that is what's took it this far.Quote:

The 830 is right at 1.10, the M3P I'm not so sure about, but I have no reason to believe its higher than 1.1ish. Practically every drive with TRIM should be able to manage 1.1 with endurance test loads.

FYI, there is a 11.5 RST Beta driver out, TRIM in RAID 0 or 1 array.
http://www.station-drivers.com/page/intel%20raid.htm
11.5.0.1171 beta does not look to bring TRIM to raid yet.
I've tested on W8 which was where one thought it would start working, there is still something missing.
(tested on a P8P67 (rev1), orom 10.5.0.1034, it might require an updated orom, so, if there is an updated bios with 11.5... OROM I'll give it a try)

A lot of things going on at the same time now. 1 PiB for the m4 today. The G1 passed 700 TiB and are going through a retention test tomorrow and I had a deja-vu today.
The Mtron pulled a Kingston V+100 on me and dropped out earlier today. Lets just hope it'll not repeat that to much otherwise I'll get really tired of restarting my endruance rig.
On the other hand the mwi dropped from 99 to 98 after 21.4589 TiB of ASU write. To be more accurate I need it to drop another to 97 just to be sure how much host write it takes to make it drop 1%.
I was thinking of testing retention on the m4 but then I might miss the chance to get it into a read only state. What do you think?
Oh how I hope that Sammy makes it to 2 PiB :D I was surprised when it hit 1.5.
I must say I'm not sure what to think of the X25-E already dropping its MWI to 98, shouldn't SLC outlive MLC by a LOOOOOOOOOOOOONG shot? As far as I'm aware, the X25-E is rated at 100,000 P/E cycles. That's something like 72 GB/day for a century.
It took 150 TiB to drop 1%. that is 14.6 PiB not taking into account WA without trim. I think it'll last a very long time but we just have to wait and see if the drop is going at the same rate or if it changes.
Edit:
100K*80GB=8PB
MWI shows better than the spec.
This is what happens when you browse the forums late at night, I read it as 23.572 TiB :/
An easy mistake to make :) At least the X25-E looks better now then?
I'm curious to see if mwi follows P/E of 1000=80 TB or like now with 150 TiB.
I'm absolutely certain that there is no read only mode for SSDs. (my vertex 4 wasn't readonly ... just crashing on write/erase activity)Quote:
