Maybe all those PB of host traffic are wearing out the PCH... but no, I don't think so. Not sure what it is, but when I was doing preliminary testing I would use my desktop, and it would be around 270 avg for the M3P. I'd put it in the e-rig, and it would do 240ish MB/s. Both seem to be doing much better, but it will be a few days before I know for certain.Quote:

The M3P is doing 269MB/s avg after 25 hours, the 830 is doing a staggering 304MB/s. We'll see where they settle.
Are the rigs set up differenty?
(drivers, AV scanning, ...)
The speed of the M3P almost looks too good to be true, how many days will it last based on that speed. (based on i.e 3K P/E cycles)
The rigs are very similar, neither has AV or anything like that -- especially the endurance rig, which is about as stripped down as a Win7x64 install can get. The instantaneous speeds are higher, not just the average.Quote:

I think the 128GB 830 would be almost as fast, but the 830 is a little more inconsistent. The M3P does 322MB/s through the entire loop just about.
The two drives could be fast enough that other factors are coming into play with regards to speed. At 269.73MB/s avg, you'll get 22,758GiB a day.Each day the drive will use about 197 PE cycles based on 1.1 WA

Avg speed on the 830 is down 2%, M3P is up by 1%.
After 37 hours, it's just about blown through 10% of the PE cycles! Exciting.
I wish the MWI implementation on the Plextor wasn't so damn lazy.
I haven't gotten to test mine yet, I've updated the firmware so they are ready.
Have you got a recent screenshot showing the M3Ps SMART status/values?
Here are a couple of charts showing relocated sector events for the intrepid X25-V. I had forgotten that relocated sectors turned up on the X25-V before the MWI had expired. It follows the bath tub curve quite well. (Infant mortalities, stability and then progressive failure).

I'm really hoping it will appear to be 5K P/E(Toshiba Type B 24 nm T-Nands).. sadly corsair performance pro's smart values arent any different than plextors
I'm not sure how upset I would be if I bought a Performance Pro and I got 24nm instead of 32nm. While it is uncouth to swap flash without saying so, the 24nn uses much, much less power. The M3P maxes out at 2.6w, and it doesn't even get above ambient during endurance testing. If it puts in a halfway decent showing, the 24nm might be what you want.
We will see how the M3P does, but previous drives using Toshiba toggle have not done well at all (Samsung's Toggle appears to be a different story).
Certainly. I'll post it later, but all current/worst values are nominal. Only power on/cycles and host writes are changing.Quote:

Thanks Ao1,
Hopefully they'll be able to make "drives" like that again.
It has been uneventful except for enduring more than any other drive, so far.
Christopher,
Just wait until something interesting happens.

So power cycles, power on hours, unsafe shutdown and host writes are the only values which increment so far.
I expect if/when a block goes bad MWI and reallocations will change.
All current/worst values are still at 100.
474556*64MiB that's close to 29TiB
I expect CDI and or others will pick up on the writes attribute, lets hope reallocations won't happen for a while, at the current speed it probably won't take more than a few weeks though.
That was a shot from last night. It's currently at 714341 (44,646 GiB). I just didn't want anyone thinking that the attribute didn't work correctly (it does -- B1 RAW * 64 = host writes MiB).Quote:

It's going to Hell, and quickly at that. I'd expect to maybe see a reallocation in around two weeks -- somewhere near 3000PE cycles or so. I hope I'm wrong though. Fortunately for me, I usually am.Quote:

I've been looking at the SMART data on the 330 and it does not look to be 3K NAND. (it could still be though)
From what I can see, Raw NAND writes points to MWI exhaustion at about 5K which means ~590TiB of NAND writes and 835TiB of Host writes.
(based on the first 5 MWI movements, the next few days will tell whether it sticks, I'm recording every 10 minutes so the change is not immediately recorded)
Heh, so basicly twice the Intel 520 60gig drive.Quote:

It's early days yet, I'm happy with the 330 so far, throughput is about where I expected it to be.

I'm kinda excited about the 330... I wonder if maybe it's just cheaper to use Intel's stash of NAND? Maybe it really is just Cherryville with 300i and not 400i FW... and no other differences.
I'd be happy just to get 5K PE cycles out of the M3P, as fast as it is.
I hope you get 10K ill be happy to know mine will lastQuote:
