Laslow posted:I guess the 840 Evo issues were overblown. They weren't overblown, people just like to panic over nothing all that significant. We knew on patch day the bugs would take maybe 20% off the drive lifespan, and the lifespan is ~plenty. You should expect first drives dead caused by the bug in... two-ish years? It does result in ridiculous slowdown and maybe even data loss if you haven't turned on the computer for months to years. And the bug does cause accumulating damage in all 840 Evo drives, but technology moves on fast, and this type of damage takes several years to kill a drive. In ten to twenty years all 840 Evo drives will be dead.

The slowdown only happens for unpatched or unused drives. The slow decay of the cells is impossible to fix and will eat all drives, including mine, in a matter of years. I invested my entire fortune into a top-of-the-line SSD only to hear it will not even outlast me, nevermind be the family heirloom it was supposed to be. Samsung didn't know how their cell technology worked in the long term, and hosed up on both cell durability and ability to store charge. Fortunately for them, they hosed up in opposite directions, so the vastly higher than expected cell durability means the damage from the decay will only be noticeable after about ten years after manufacture, assuming the drive is patched and turned on routinely. In order to get the decay damage to show up sooner, you'd have to be running the drive way above its expected cycles anyway. It does mean the drives are much worse for static data storage, but eh, when the 840 was new that was a thing you wouldn't do with SSDs anyway.

LRADIKAL posted:Your biggest fastest drive should be your boot drive. Throw the 128 gb in the trash. I have simplified your issue. 128gb is fine for a boot drive. In fact, it's drat near perfect. Any kind of recovery is easier when your data isn't on your boot drive. If both drives are a SSD, you won't notice the difference. Also Raid0 is the perfect way to backup your data, that way you can make sure the important things are safe.

That's not the kind of recovery I'm talking about. Backing up your OS state is more often than not worthless, because you're facing a reinstall when Microsoft fucks up again, and not having to care about important files on the boot drive is great. Also, using Raid0 instead of backups gives you certainty about the state of your files in the case of a device failure, and if you're using Raid0 and not backups, you won't lose anything important when the device fails, so the end outcome is the same.

Its Coke posted:What's the SSD equivalent of wiping a hard drive with a magnet? Farting loudly. Does about as much. First of all, wiping a hard drive with a magnet isn't precisely very secure. Or convenient. Meanwhile a secure erase of a SSD is usually good enough, but to be sure you need a hammer. A home user isn't going to get anything out a securely erased SSD, but someone with a real budget might.

The question is is anyone going to dig out the chips and harvest your data from them. Secure erase and overwrite (do both) will make the data very time-consuming to access. Not impossible by any means, but difficult enough you have to ask if anyone is going to bother. For securely enough erasing hard drives you overwrite them with random data and then zeroes. This won't necessarily stop people determined enough to use an electron microscope... but then, if someone is willing to go to those lengths they probably already have your data unless it's exclusively stored in a high security facility. A magnet is just bad though. It's impossible to verify you've got all of the data erased until you're at the point where crushing the drive would be cheaper, safer and easier. (You want secure erase and overwrite both because manufacturers have been known to get a bit lazy with the encryption. Kim Bongbong's story is the funniest.)

Lutha Mahtin posted:The question of "what is my threat model" is certainly a valid one. If you aren't the target of a nation-state intelligence actor, or you aren't trying to erase "moneylaundering.xlsx" then snapping the board in half and tossing it is more than sufficient. Proper and through procedure in this matter is device homogenization with an industrial shredder, and totally prevents reuse. Close E. Nough meanwhile is, well, close enough for home users without anything especially incriminating on their devices. WhyteRyce posted:There is pulling ones and zeroes off, and then there is actually pulling off data into something that is actually readable or usable. How much of the later actually happens? The latter is pretty easy in a lab, but you'd need a well-staffed university-grade or better technology lab. If you're determined enough to make do you can just pull the flash chips and get useful data on a home budget, but it's still a lot of effort to find someone's browsing history if you don't have a specific thing you're after. Unless you're putting poo poo through an industrial shredder you're not safe from someone who really wants your data. Not that even that is foolproof, if the fool has a multi-million budget. The only foolproof method is melting the device down.

Its Coke posted:Would a hammer 100% make the data unrecoverable? Technically speaking you cannot delete information. The data is never truly unrecoverable. For practical purposes, even a hammer or an industrial shredder (or a high-power blender) will not guarantee it because someone could have the budget and inclination to have a bunch of very specialized technicians reassemble the device with some very expensive laboratory tools. As much as it may look like a million grains of dust, ultimately those bits go back together in only one configuration and that configuration is practically discoverable, if hideously expensive and time-taking to find. You can even melt hard drives and the data is still technically recoverable, though that would take more time than anyone is able to wait. The go-to answer is a shredder for e-scrap, though. They're reasonably affordable and do the job sufficiently well that there's very little data worth protecting from an adversary who will go to the length of reassembling the drives.

GRINDCORE MEGGIDO posted:I would really like to hear of any actual legal cases using data from a blended, securely erased SSD. Never going to happen. Anyone with the means will have easier ways of getting at the data. It's one of those "we know it can be done in a lab" things, not that anyone will* actually spend the time required to actually pull it off. (* Except as a Stupid Academic Trick because they're bored and/or just to prove they can. Never underestimate how drunk and/or bored academics get.) Shredding the hardware is sufficient against any reasonable adversary. Melting the hardware is overkill you would maybe want if you have a high-security facility. I'm mostly just having fun with the concept of "100% unrecoverable". Nothing is actually 100% unrecoverable though recovering any usable data from a melted hard drive would take technology far beyond what we have now. If you're crazy enough you can read individual flash memory cells and piece together a SSD from shredded remains - some shredders even will leave entire flash chips intact.

Atomizer posted:I've got a few CS1311s (IIRC 2D MLC, DRAM,) still going strong, and one or two CS900s still running fine somewhere around here. I wouldn't hesitate on those CS900s (although I think they're DRAMless) as cheap, straight upgrades from HDDs. That pricing sounds similar to what they'd go for in the US (~$20 for that capacity) so unless there's something cheaper or slightly better for a little more money then those should be fine. With our sales tax, $20 is €21. Still a third cheaper. It's the CS900 120GB that's suspiciously cheap. The 240GB is €38 compared to a WD Green for €36 and I'd grab the WD Green over it any day. The systems still booting off a hard drive aren't exactly performance monsters, so here's hoping the ones I grabbed are reliable.

There is a 3DS thread. Also, no. There's literally nothing left to do to get that thing back to "working". Probably some tricks if you really want to copy off the data, but it's not staying alive long.

nielsm posted:Secure erasing an SSD is extremely fast because it actually just needs to wipe some bookkeeping data about how the actual data is stored. This actually includes an encryption key, because encryption is a good way to make sure the bit patterns appear as random noise, and flash memory cells are work better (in some way) when storing "noise". Without that encryption key, recovering data from the flash memory is effectively impossible. Except for some devices... ... didn't the list of devices include the 840? Filling the device with effectively random data improves your chances of not getting owned a lot.

I ain't trusting Samsung to implement poo poo sanely after their repeated failures to do that very thing. Do not do it with dd unless you know what you're doing though, it can easily wreck flash memory if you're careless.

Thanks Ants posted:You might be thinking about partition alignment, but I'm not aware of it preventing things working rather than just affecting performance. Partition alignment can prevent things working if you're using something downright silly, like a SD card or a flash drive. It can still cause write amplification like this though.
