A full cleaning is what you need, if they are noticeably slower that is.

I've found a winner.
After much consideration, I think I found an optimal mix of controller, size, and NAND type.
Hopefully the drive will ship out tomorrow and I can start abusing it by Friday.
Hmmm...
Not quite.
I'm not really interested in sequential read speeds(For testing purposes), but it is kinda cool that Crucial is bringing out new FW.
Also, there is already a M4 in the test. And a C300. I had a M4 64GB too, but I put it in my Mom's laptop last time I flew home. It was genuinely, proper fast. It made me feel dumb for paying more to get a 510.
I'm not really sure I should give a hint... I don't want to jinx it... Once it ships out, I'll clue you in. I have faith in UPS and FedEx.
I would feel supremely idiotic to name the drive, and then the etailer screws up (had this happen recently).
I don't think it will be an issue, but just to be on the safe side I swear this oath:
If I don't get this particular drive by Monday (maybe Tuesday), I'm starting the test with my Intel 510 Monday night (maybe Tuesday??)
The 510 only has 593GB of host writes on it, but only had 498 before I started playing with AnvilPro's endurance testing yesterday. It's pretty fast, but since it's 120GB, it's only about the same as avg write speed : capacity as the M4 64GB.
The drive isn't even on the manufacturer's web site, isn't listed or is listed with a "usually ships in 2-4 weeks" at the few etailers that carry the series -- and I think the etailer that I placed the order with doesn't really have them. So I put in the order anyway, and I'll just have to wait and see. That's why I didn't want to mention it. I'm actually incredibly excited about this particular drive. I probably shouldn't have even mentioned it, but I couldn't help myself.
I think I might be addicted.
I will curl up into the fetal position and cry like a little baby if they don't have this drive sitting in their warehouse in West Nowhere, just waiting to get on the truck.
well this is piquing my interest for sure...cmon out with it! which drive?
@also...this quasi-failure with the intel has just really impressed me. much more impressed with that drive now than i would have been had there not been a failure!
I have my two drives limited to a 60GB array (so some reserve space there on that front), and its sitting with 10.5GB free space (trimmed down win7 install...I need to reinstall to be able to install SP1 one of these days +autodesk programs)
judging by a recent CDM 2.2 when comparing to virtually brand new I'm looking at...
sequential:-110MB/s reads, -8.37MB/s writes
512k:-33.9MB/s read, -25.98 MB/s write
4k:0.12MB/s read, -9.97MB/s write
one drive has 9710 power on hours, the other 9748 and 1.20TB and 1.32TB written respectively and most of those hours (give or take maybe 100) have been in a RAID array in win7
im sure there's also been a firmware revision since I installed my drives
I know the drives are pretty tough little cookies, I'm just now wishing I could get myself a third or fourth, lol
Would be good to know what the drive was.

I'm still trying to figure out why it drops out, so the test is still halted.
Really impressive to see the Crucial M4 getting above 500 TB. Will see if it really beats the C300 etc. but I highly doubt it because the controllers are pretty much the same and the 34nm NAND is much better etc.

WOW it really is impressive to see how much better SLC is compared to MLC ! The Intel X25-E lacks TRIM but has a WA of 1.1 and 50nm SLC NAND. A M4 has TRIM and WA of 1.1 and 34nm MLC NAND. Sandforce often has actual 0.6 WA which is very nice and TRIM too etc. Capacity also plays a role here. For example a 64GB X25-E will last twice as long as a 32GB X25-E !
Imagine the almost ideal scenario for SSD endurance ( which does not exist currently but the technology is there ) : 90nm SLC NAND, 256GB capacity ( tons of reserve space too ), WA of 0.6 with compression controller like Sandforce and TRIM too etc.
I can't.. bought it like this - just got in today... I wondered WTF the guy did with it as well.
That X25-E averaged ~31.7MiB/sec for ~7.5 months in real usage :eek: :lol:

wow looks like a server drive, bet it was used in a caching environment. Cache disks can take a beating, but damn that is alot of resets for a server scenario...interesting, a good mystery!

Just out of curiosity, can you detail a little (if allowed) what kind of load do you have on that SSD? I am asking because on normal desktop usage and light servers I saw no more than 5-10TB of data per year until now.

i'm following this thread with great interest, admiring the great job done by all participants and learning a lot.
With risk of being obvious i'd like to remember that with respect to Intel Toolbox Smart Attributes, some of them seem not to be very reliable, since there are old complaints about them in Intel SSD's Forum, like this one:
[QUOTENov 16, 2010 4:34 PM
intel G1 ssd reports weird unsafe shutdown cont][/QUOTE]
With me, one new G2, just after OS installation, toolbox was showing about 2 or 3 TB of host writes.
Keep up the good job.
