SSD Write Endurance 25nm Vs 34nm

[B.A.T]

Exciting!! A 3K unit . How does it perform?

[Anvil]

Hard to tell!

It's on it's 4th loop.

Currently it's about 25MB/s faster than the Corsair Force 3 (Async) but it needs 20 hours to get to the first reference point I've got on the F3.

Not sure what settings I ended up using on the F3, will check.

[B.A.T]

Need maybe a couple of days to stabilize?

Did you do the standard benchmark?

[Anvil]

It will need some time.

I'll post the benchmarks later, ran a few different compression settings for later comparisons.

Not sure it they do some sort of testing as it had > 30 power on hours, next to no writes though. (kept the screenshots)

Here's a link to the F3, ~24 hours into the test.
(doesn't look like the links are working properly, it's on this page though, post #1693)

edit:
21+3 hours for the F3 so I'll compare them when the 330 has been running for 24 hours.

[B.A.T]

The Force 3 did 8K GB each day so if this goes past that it's a pretty good contestant.

[Anvil]

Average speed is in the low 120s, loop counter is at 33.

The pauses at the end of the loop (deleting and TRIM) is what is killing the average speed, the drive is doing about 140MB/s throughout the loop.

It's already well past 1TiB

[canthearu]

The BSOD is 0x1A error code. (memory manager)

I am able to get linx to fail as well, so it isn't to do with the drives!

Yep, I saw the same on my vertex 4 ... at least on the older 1.3FW .... 180gig or so average speed, bought down by the delete cycle to 145meg or so.

Anyway, woot for the 3k unit .... lets see who wins, the bigger 330, or the smaller but higher endurance 520.

[Christopher]

I'm sitting at 1.51PiB LBA writes at the moment. Not too shabby, but I was really hoping to hit 2PiB before 84 days. Probably will be closer to 90.

Now that Anvil's dropped the new drive, I feel like I should toss another one in there, too. Suggestions?

[Anvil]

It's already past 2TiB, avg speed is 123.nMB/s and that includes 3 rounds of MD5 testing.

As the 330 is twice the capacity of the 520 I'm optimistic on behalf of the 330

Christopher,
I'll just throw in a few suggestions in no particular order

- Kingston 3K
- SanDisk Extreme
- Crucial v4 (a new series of "low cost" drives, SATA 3Gb/s with OK write speed for a 3Gb/s drive, low iops so not sure how it would perform)
- Corsair Performance Pro
- Plextor (if you can find a "cheap" one)
- Something upcoming using the 88SS9187 controller

It should be something that is not dated other than that it's up to you.

[Christopher]

I'm thinking about getting a 256GB M3P and runnin' the 128GB M3P! The speed is downright magical, and I think it would be worthwhile. I have a 3K and the Mushkin Enhance Chronos Deluxe 120GB still, might be good to get back to my roots, but I don't know if another SandForce is where I need to be going. The Extreme is still interesting though, but I want a 128GB that's as fast as the 830.

[Anvil]

I agree about not going SF, something new would be good. (other than SF)

[Christopher]

Phison's new 6gbps controller is out... but I don't know if I'll be rushing out to buy one.

I reckon that the M3P 128GB could burn though 21TiB a day, using about 186 PE cycles in the process, or around 1300 a week (~147TiB). That's not terrible!

[Anvil]

What drives are using the Phison controller?

[Christopher]

The new MyDigitalSSD BP3 up (up to 512GB) using the S8 Phison. It's... how do I say this... about what you'd expect. I still want to play with one, though.

[Anvil]

Well, maybe in a few years one could get a 512GB drive at a reasonable price for using in this thread

Are there any reviews on the Phison that you have noted?
(a few benchmarks could tell if it's worth spending time and money on something using that controller)

I checked in on the 330, not much have changed except for TiB written, it's down to 122.x MB/s over a 12-14 hour period.

No movement on mwi for the E even after 100TiB of writing, wonder when the first drop will come. Besides that all 3 have been very stabile the last 12 days. Writespeeds are barely moving so it looking good.

[canthearu]

BIOS update may have resolved my stability problems (I was running a VERY early bios version, the very initial version), running linx in background to check.

Edit: Vertex 4 at 214 reallocations. Still working though

[Anvil]

That's good news, using the initial bios version often is risky business.

214 reallocations, that should translate to 214 bad blocks, not sure how many MBs per block on your drive. (there should be plenty left)

The Crucial m4s are showing factory bad block count which in some cases (on some of my drives) exceeds your current bad block count. (if we assume 1 reallocation consumes 1 block)

[canthearu]

That's good news, using the initial bios version often is risky business.

Yeah, I jumped on the Z77 chipset very early because I wanted Intel's USB3 rather then a 3rd party chipset. But things are starting to be ironed out now:

a) Updated BIOS seems to have fixed stability.
b) Updated Intel graphics drivers have helped.
c) Updated RST drivers (11.1 rather then 11.0) means smartlog is working right now.
d) Updated crystaldiskinfo now shows thresholds like it should.

But one good thing is that boot times are excellent!

[Anvil]

No, that's Samsung Toggle mode NAND.

The capacity of the drive leads to those figures.

[Christopher]

holy crap is that SLC flash?

No, it's just 256GB of thunder and lightning. It's comparable to a 64GB drive with 409TiB (~419,580 GiB). Not terrible, but not earth shattering either. At least, not yet.

I got tired of the drives I was running not putting in the kind of performance I was hoping for, so I had to reach for a bigger hammer in the 830 256GB.
