    For now, I'd still get the 830 ... it is cheaper and has beetter NAND. It is also well proven in the field.

    I won't argue with that!

    But here in the states, the 830 is getting harder to find at such economical prices. I think the 830, while slower, isn't noticably outclassed by the 840 Pro.

    Wow! 6PB!! I wonder if the forceGT can even come half as close to that!

    I know canthearu is testing the Samsung 840, but is anyone on here testing an 840 Pro by any chance??

    That's the equivalent of 8PiB on the 830! Excellent.

    Cheers for good work!
    There is also quite intense durability IMFT(Micron)?s NAND and of course SAMSUNG.
    The durability of the NAND itself is a problem that becomes overspec

    I hope they'll provide the oven and crucible to handle hours of baking at 800C/1,472F...

    J/K...lol

    Does make ya wonder if a 2.5in. enclosure could handle that kinda heat even if only applied to a few cells at a time. ATM it's looking like nand rebust-ness isn't too much in question a la the 6PB 830. I'm beginning to suspect it's the controllers that can't handle the milage. hmmm...

    Nah, the controllers themselves are pretty rugged. They have higher Tmax ratings that the flash itself, but the firmware is a different story. Obviously, higher temps skew Vth, but a super short burst of high heat might be the ticket to making that stuff last longer.

    I do sometimes wonder about the drives using overclocked ARM silicon... that could be an issue long term.

    If Samsung 840 survives past 5000 cycles, then it will be a true wonder.

    I don't know if you guys remember, but several months back one of my X25-Es died after a FW update (I think we were talking about X25-E FW and I found out the first FW revisions were bugged). After the lock up, just having the drive connected was enough to lock a system up, and after contacting Intel support, I couldn't get my hands on newer OEM-only FW.

    The good news is, I took it out of the gear closet yesterday, and I was able to SE it with RHEL. It works fine now. I'd tried this a couple times over the past few months, but for some reason it worked this time. If only I could do that to one of the dead MTRONS.

    There wouldn't be any problem with the current form factor of NAND. Baking operations would be realtively rare (once every thousand writes or so) and would only affect a few thousand NAND cells at a time. As long as the casing around the heater elements can handle the heat, it would be dissipated in milliseconds.

    Maybe secure erase will become "erase and bake"

    It does have a nice ring to it...lol

    I see your point re: the rarity of an actual bake operation. They could add some thermal pads and use an aluminum enclosure problem solved...that is errr, after the tech is fully developed.

    I'm going to assume you OP'ed the drive at least the amount suggested by Samsung Magician v3.2.
    Have you been running the Magician Performance Optimization occasionaly?
    This does GC and manual TRIM and will/could improve read and write performance.

    Just a suggestion.

    Nope, no over-provisioning nor explicit performance optimisation ... but it isn't really required on a drive with working TRIM.

    These things help most on drives that are have demanding 4kb I/O loads on near full drives, and virtually no difference on desktop loads (ASU included, as it runs a desktop type load pattern) with working TRIM.

    Alright, people. I have an announcement to make...

    The 830 is on life support.

    It probably would have made 7.5PiB if I had just let it be... it had been running for 3775 hours continuously, without a power cycle. Unfortunately, I had to move to a new apartment, and so powering down the system was unavoidable. I had everything choreographed, and I was able to get the system powered back up at the new place in only 10 minutes. Sadly, this was too long.

    I'll post some more information later, but it seems as though the <10 minutes was enough to cause all sorts of uncorrectable errors. For the record, the system detects the drive, but attemps to access it result in long hangs, and the partition and static data are toast.

    It's a crying shame, too, because I figure the drive could have continued until all spare blocks were consumed. It was approximately 30% of the way through all of them, and so another month or two would be all I needed to kill it properly.
