Changes since last update:
-The Mtron dropped out 1 time. I'll be pausing the endrurance test on the Mtron until Iæll figured out how to update firmware on it. I need to find some documentation first.
- I'll updatet to the lastest firmware on the m4 to avoid the 5K bug. The update went well and the drive runs normal again. Only change was a smal increase in Cumulative Corrected ecc because it was without power for aprox 1 hour.

@Anvil
Can you update the first post with the new firmware on the m4?

@B.A.T

Will do

What's the final verdict on the Plextor?

Attachment 128269

The M3P is dead. I couldn't get it running for more than a few moments; It's quite curious actually.

However, today I tried the drive out, and all the data was there, I grabbed some more smart data (a lot more reallocations were seen vs. the last data I posted). Now the drive can be detected by the UEFI, but no dice. It will hang the system now, so looks like it's all gone.

Here is the data I grabbed before death:

Attachment 128288
Attachment 128289

896.699 TiB in host writes. I did manage to figure out what all of the smart attributes are though, so that's a plus.

I really liked this drive, it's sad to see it go. It probably used over 7800 PE cycles, and while I was hoping for more, the drive is just way to damn fast.

sent my contact at Plextor the above info and 3 days later I get this reply

Hi *****,
Plextor SSDs have been through testings by our RDs. For heavy users, the maximum could reach to 20G/ day. It can write about 36.5 TB/ 5 years. TiB written 856 could be used for 115 years.
- Plextor

I also linked then the thread, I'm quite disappointed in the short time it took to get the drive to fail it did go fast while it was kicking.

---

I know it is disappointing to see a drive die early ... but it did do twice the specified P/E cycles of the NAND.

So a fairly average result ... but not bad at all in real world terms :)

I wouldn't call it disappointing, shrinking leads to fewer P/E cycles, binning/QC can make a difference.

MWI behaves differently from other drives though, could be that this is just as good as being based on "P/E count".

I'd say it did well!

--

The 330 lost 2 more sectors, current count is up from 2 to 4. (happened during the night)
B5 and B6 looks to go hand in hand with 05 and are both up to 2.

I actually was speaking to a intel rep and showed them this thread and they said they would closely follow this thread and investigate the quick failure rate of the 520 series drive.

Well, I still have that Intel 520, your rep is welcome to contact me regarding it (and getting it back).

I am intrigued about the reasons behind the panic locking death of my Intel 520.

I was only dissappointed with the M3P because I really thought it would reach 1PIB. It was using twice the number of PE cycles as the 830 with half as much flash. It's still a fantastic drive.
--Good thing I have another!

I don't know whether the MWI on the Plextor was spot on or whether it was just a coincidence. I don't think it was the erase failures, but it was the read failures that did it in (IMHO). MWI is based on reallocation events, but it only had 15 read failures.

The 830 has been averaging over 300MB/s for the past four days! Crazy.

If I were to run another 128GB M3P but artificially reduce PE/day, I think it would make it to 1.5PiB.

I've been thinking about making an option for reducing throughput, not set yet but it might be interesting.

Not sure if the Plextor fits the "Drives that did not meet MWI spec" chart as MWI is handled differently, I'm leaning towards putting it in the standard chart.

Great work. I find this thread fascinating. Also I thought Intel 520 would go on forever, but it looks like the Sandforce controller is a let down, as it died without even reporting relocated sector counts first.

Don't forget though, the 520 is a desktop drive based on MLC. It won't receive the absolute best NAND, as it has already been turned into eMLC for their enterprise products. It's tested life, at roughly twice the specifications that Intel put on the nand (10k cycle real life, 5k cycle rated life) was still quite good.

It's far better than OCZ's NAND, but compared to Samsung 830 it's dissapointing for the reason that the Intel SSD costs considerably more than Samsung 830.

Lets not get ahead of ourselves, the samsumg hasn't even reached the same amount of writes as the Intel 520 yet ... at least on a per gig of accessable space basis. The samsung drive is 256gig, the intel was a 60gig.

A bit early to be decrying how much the Intel drive sucks, especially when there isn't a hope in hell that any desktop user will reach the MWI on either the intel or the samsung.

In any case, both the intel 520 and the samsung 830 is a great drive.

Yup...size does matter with ssds...lol The amount of over provisioning also plays a role re: endurance...the 40GB Kingston (Intel X25-V) is a prime example, afaik it has 64GB of nand on board. As a rule I run all my raided drives with 33% OP and my OS drive at 28%.

The X25-V does not have 64GB of flash. The X25-E was over provisioned (32Gb had 40 and the 64GB has 80GB).

As fast as the 830 is, it's equivalent to the 64GB M4 on a speed per GB basis.

Right u are...I some-what remembered that there were some older intels with lotsa OP...just not which ones.

Do you know how much nand these drive actually have? If I remember correctly the Intel controller has 10 channels, but just half are used in the V models? I still have a couple of the Kingston versions flashed over to the Intel firmware so they have trim. Not that it does any good as they are in a raid0 situation. Great little drives.

Edit; just opened one up - it does use 5 of the ten channels with 8Gb chips = 40 Gb total.

Yes, the Vs have 40GB onboard, occupying 5 channels. The 311 is the same way, but the 320 40GB has 8 GB of redundant flash for its parity scheme.

Thanks! That drive needs all the encouragement it can get.

So...

Based on the MWI progression versus the TiB written for the X25E, it'll hit 12PiB before MWI reaches 1... Granted, there may be other factors but I still find that ridiculous!

it IS SLC NAND... so it's not really that ridiculous

And it's got 80GB of 50nm SLC at that. In reality, you should get closer to 300K PE cycles out of it.

300K PE cycles would be ~8.65 years of endurance... in which alot of things could happen. The end of the world could come, or some meteorite could strike it... or Mrs. Bat with a hammer :D

At the current speed it does 2,6 PiB/year. I think something else will break before the nand and to be sure I'll be wearing a helmet and the endurance rig will stay hidden :rofl:

Drive has finally reached it's official worn point. It has been a good run, and drive is running a bit faster then it did when I first started it. Hopefully I can at least double the amount of written data. Unlike the earlier corsair force 3 .... Wear range delta has remained very well controlled, which may improve the eventual life of the drive.

Looking through the SMARTLOG data, the drive hit MWI 10 at:

Thanks for the update!

Looks like the non-Intel SF drives are a bit different on MWI, I've still got 27% (or 37% depending on how Intel handles the last 10%) left on my drive and NAND writes are up to ~380TiB.

Your intel 330 will go all the way down to 1%, just like my Intel 520 did.

Intel ported their method of measuring MWI to their sandforce drives, so the MWI goes all the way to 1%. Will be interesting if the 330 makes it all the way to 1% though .... did intel forget to set the NAND cycle feature to 3k rather then 5k on their 330 drives ... or does the 330 really have 5k NAND in it.

Also, if people are looking for a drive with Plextor M3 like performance, but don't have plextor stocking their part of the world ... keep an eye on the liteon drives.

I got the following from a $90 AU Lite-On - LZT-128M3S (128gig).

Attachment 128491

The scary thing is that inside the outer casing of this LZT-128M3S, there is a mSATA converter and a Lite-on M3M mSATA drive.

Such performance is completely nuts from a normal desktop drive, let alone a mSATA drive!

I could have checked how it was handled on your 520. (a bit lazy as it's holidays sort-of)

Here's a look at Reallocations vs MWI on the 330

+1...That mSata would be more than welcome in my notebook.

Where the hell do I find such an oddball drive as that Lite On? That has my name written all over it.

Just keep an eye out for bargains. Then don't hesitate because they sell out quickly.

The Lite-on drives are very similar to the corsair performance pro and plextor m3 drives. 24nm Toshiba NAND on a Marvell controller. SMART parameters are very similar (if not the same) as your M3P that was tested. However, it seems that my drive is no good at counting power on hours. Been powered for 26 hours and only showing 1 power on hour. Could be due to some power saving mode.

I just tried to update fw on my Mtron but I just get this error message, both in IDE and AHCI. Got any ideas?
Attachment 128524

I used the 0.20R1 ver posted here this spring.

BAT,

No, my FW updates went off without a hitch, I just burned the ISO files to CD or on USB and booted. In fact, I can even update the FW of the dead MTrON (the one I don't fry). I got my Fw updates from Imation.

I've taken a look at their homepage but where can I find the download page with fw?

The last time I looked, MTRON didn't even have a site anymore.

I ment Imation homepage. The Mtron homepage is down wich makes it not easy to find anything useful.

Were you trying to flash your MTRON with the Imation FW?

Hi! Do you by any chance have the 18r or 19r? The 20r returns an error and won't flash.

I'll try flashing one of my Imations with it.

Good luck :up:

I feel like the 830 should have more reallocations than just 9 at almost 3PB. But if we scale it down, it's a lot like the 64GB M4 with only .75PiB on it. Its even 1/4 the average speed of the M4.

I might start looking for another drive as well.

@christopher
Your Samsung has been performing better than expected, drives of such capacities are in a different league from smaller drives like 64GB drives.

I'm still thinking of creating an option for running at a reduced/fixed throughput and or combining with reading data on top of writing.

Anvil, my sandisk extreme seems to be missing from the list of drives on the first page?

Can you fix?

Ugh, will check whats happened when I get back home. (tonight)

edit:
Should be OK now, not sure how that could have happened.
(I do keep backups :) and that made it a quick fix)

Ok, new drive time:

I was kind of disappointed in how the first vertex 4 went ... so it is time to kill another:

This time, I'm going to change the rules.

Drive settings:
Firmware version: 1.5
Overprovisioning: 60 GiB
Static Data: 16 GiB

I am overprovisioning the drive so it stays in performance mode permanantly. I think the constant switching between performance and storage mode, as well the garbage collection the switch caused, was making the drive use excessive write cycles.

There are many new factors that may influence the way this drive goes:

a) If the drive is using NAND in an SLC type fashion, then each erase does twice the damage over normal MLC, as each erase cycle would only be wiping one bit, rather then 2

b) The drive may take a lot less damage during writes if the NAND is being used in an SLC type fashion, as each cell is only written once each pass.

c) Reading the data may be easier if each cell is only written once. Thus the drive may last longer due to less ECC being needed.

How this ends may really be up to how the NAND behaves.

Attachment 128566

That one should be interesting!
It might help on finding out what's going on "behind the scenes" on the V4.

Over-provisioning has been on my list of things to do for quite some time, to get to the interesting parts one needs 2 drives where OP is set differently. (both could be OPd)

How is possible to use it as SLC? is there any firmware configuration that allows the cells to be programmed in "SLC" mode?

Yes, in a roundabout way. There was an excellent summary and re-review of the 256GB V4 (w/FW 1.5) explaining how the performance/storage mode works as well as the mimic-ing of SLC on RWL but now the link just reloads the home page. :/ The new 1.5 was supposed to extend performance mode past the 50% barrier by tweaking garbage collection as well as give a little speed bump.

It's more accurate to call it MLC-1 than SLC. When flash stores two bits, the first bit gets programmed fast while the second takes much longer. So if you just write to that first bit, you get similar performance to SLC.

Actually that's where I saw it...musta had a toke or two. :peace:

The 256GB V4 re-review w/fw1.5 is still a good read if you can get to it...I informed him of the broken link.

The Recovery time white paper discusses MLC-1 briefly.

That's probably true, but real MLC-1 also gets SLC like endurance. Perhaps only writing to one half of the drive will change the outcome this time?

Very impressive...the 830 has proven to be a very solid performer to say the least. I wish I had the extra resources to test 1 or 2 more large drives (240/256) and see just how big of a roll drive size plays in regards to endurance.

Attachment 128668

Hmmm, I seem to be getting some performance degredation ... something triggered the drive to shift to storage mode rather then performance mode. The attached picture shows how each run starts fast at about 400meg per sec, then drops to around 200meg per sec.

Will secure erase and see if that fixes it!
