necrobobsledder posted:What's this "insurance" you speak of? I've had 3+ of these shucked drives fail just right outside their warranty periods and given nearly every credit card I have terminated their extended warranty programs would pay a little bit more per drive to have some insurance instead of eating the $450 I've lost to those drives. It just means buying more drives at the same price thanks to the shucking discount. For example, a retail 10TB WD Red runs $270. A 10TB Easystore is regularly $180. So you can buy three Easystores for the same price as two retail drives, so you can toss one on a shelf and "self-insure" against failures outside the warranty period, since statistically you shouldn't have that many of them failing. I'm pretty sure several CitiBank cards are still doing their 24mo extended warranty, so you might want to give those a look.

I'm talking about self insurance. The spread between the cost of the shucked disk and the "real" red disk is money in your pocket. You take that money in your pocket and in 0-5 years when your disk fails, buy a brand new easy store right off the shelf with your saved money. Future inflation bucks and the march forward of technology mean that disks should be cheaper then than they are now, compounding your savings.

DrDork posted:FWIW I've been shucking drives for DIY NASes for years (including rebuilding one a few months ago) and have never had to fuck with a 3.3v pin. I've had to tape over the pin on the two drives I've shucked. One EasyStore 10TB for my desktop last year, and last week a 14TB for my NAS to gradually replace the old 5TB reds that are starting to give up the ghost. I am very stupid and clumsy and easily get frustrated like a small child and still managed to safely shuck and tape them. I do keep the box and enclosure though, I stuff a little post it note with the bay and serial number in the box Just In Case I need to match them back up for an RMA.

Hmm, looks like Costco's Citibank can cover me for these drives. Too bad I chucked them after the WD warranty expired and the one I sent in was denied. Need to hold onto the original controller boards to match them with the drive it appears. Pretty annoying holding onto all this stuff when I'm trying to keep my equipment sprawl down but these drives are worth a decent bit more than most of my stuff so it seems like a fair trade-off. I'm close enough to breaking even enough with the Easystore v. retail NAS drives even with 4 drive failures out of 11, one of which was RMA approved, that I'm re-thinking the math. Never had this kind of drive failure rate over 8 years of a mix of WD Greens, Reds, Samsung Spinpoint, and Toshiba 7200 RPM drives. In fact, had zero failures of my Samsung and Toshiba drives despite being half my set of drives over the same time period.

Those Toshiba drives are tanks. The ones I have are far older and have outlasted multiple (real, nonshucked) Reds. If Easystores weren't a third of the price I wouldn't be fucking around with WD at all.

Synology's goal is to become the Apple of NAS, aka, it just works, and it can use some stuff to add on to it, but it comes with all it needs to do the job. A word on Synology Datasheets: All datasheets are written up from when they originally built the machine. Therefore as long as they have a 64 bit processor and ram to handle them, they can handle pretty much the max that the hardware compatibility list shows.

I've got the following with no problems: 13 - 3TB WD Reds that are 8 years old 5 - 5TB Reds that are 3 years old 8 - 8TB+ Reds that are shucked that are from 6 months to multiple years old However, I'm not really confident that anyone's experiences here really mean a whole lot statistically speaking. I'd buy pretty much any major brand for a good price.

I have a pressing need for some storage coming up soon, and need some guidance. Even though I have a box I built a few years ago, I haven't touched it in over 6 years now (it's been powered off for 5 years) and I really don't want to comb through what remains of the NAS4Free documentation to try to spin up or migrate my ZFS pool and have it just go kaput almost immediately since it's a 4x2TB WD Red array. Starting from scratch and going with a Synology seems like the best bet. I'm thinking of getting a DS1819+ and filling it half up with either 8TB or 12TB drives and expanding later if I need to. Can you add more storage to a Synology pool later or it is like ZFS where you define the pool and have to migrate to a new one if you want to expand? Is there any compelling reason to get the SSD caching expansion card if it's going to be for backups and maybe some streaming? Should I immediately up the RAM from 4GB to 8 or 16GB? Is there anything I should look out for?

Use this to see how the math shakes out: https://www.synology.com/en-us/support/RAID_calculator I use the SSD Read Cache because I had a literally-free SSD so I slapped that bad boy in there. I think it has a placebo effect of making my time machine backups faster. More RAM is only needed if you run a lot of services directly on there, or want an even larger block cache. I wouldn't worry about it out of the gate, I upgraded mine because I ran crashplan (Java lol) straight on the device. Today I wouldn't bother.

Phone posted:SHR2 = RAID 6/RAID Z2 it seems? In the sense that you can tolerate 2 drive failures before data loss, at the expense of surrendering two drives to parity, yes. 12TB Easystores are currently $180, making them substantially more cost-effective than 14TB $250 drives if you don't need the extra space. Unless you're really planning on keeping the enclosures around in case you need to RMA them (and some people have had luck just RMA'ing the bare drive), a screwdriver and 10 seconds of snapping the little retention clips is all you need. If you have a drive that doesn't seem to work right in your Synology, google taping the 3.3v pin to see if that's the issue. I've never had that problem, but some other people have.

People on Reddit have also have had some luck with RMAing bare drives. Apparently the only 100% not gonna be accepted plan is to put the wrong drive back into a different enclosure--the S/Ns not matching up makes WD get uppity. But, yeah, statistically you're unlikely to need to RMA them after 30 days but before 2 years, so if they're cluttering your space, just ditch the things.

I basically keep the boxes a couple months and if I don't see failures then I toss 'em. I've yet to have a drive fail on me within the warranty period so I'd rather just float that risk rather than wasting all the physical space keeping that stuff around. By the time they do die it's usually time to start the upgrade phase again and migrate to bigger disks. I can say that Seagate does track which drive came from which enclosure though, their warranty checker tool does tell me that much.

Doing slightly more research last night, it seems like running each drive through a pass of badblocks isn't the worst idea in the world? Or is it on the same level of 7-pass DBAN NSA ApprovedTM fud?

Or is it on the same level of 7-pass DBAN NSA ApprovedTM fud? NIST has a whole report in a pdf on it, but as for DBAN, it's worth noting NIST does point out that it is the only form of secure erase that has any chance of working - sdelete and similar tools that work on a filesystem level have no provable effect against anything but the lowest common denominator of forensic data recovery. NIST also recommends using FDE because the ease and speed with which cryptographic erasure can happen - although whether you'll want to trust hardware-implemented FDE such as the OPAL spec with the ATA sanitize command is an entirely different question. Highest level of forensic data recovery protection always has and always will be: https://www.youtube.com/watch?v=2iWB7FkuM_4 (Warning: mechanical shredding of disks is LOUD) Is it wrong of me to have written this post, just so that I can link to that video of harddisks being shredded?

Reply is not edit. Mind you, DBAN doesn't account for data recovery from a hard drive using magnetic force microscopy where the physical sectors on the platter are read by a head that's at a perpendicular angle whereas normally the disk would be straight over the sector - although only with a cap between the disk and the head of about 700 pico-meters.

I brought up DBAN, specifically the 7-pass, as shit that was parroted for years that was ultimately a colossal waste of time since 1-pass is sufficient; however, there would still be people online saying how they do 20 passes and they were being serious. The question was more of "run badblocks y/n?" because I don't have any first hand experience with it. e: D. Ebdrup posted:Reply is not edit. ![]()

D. Ebdrup posted:The thing to realize about badblocks (badsect on BSD systems) is that it does nothing for you if you don't then supply the database of bad sectors to your filesystem as it's initialized (or during a fsck, at least for the combination of badsect+UFS on FreeBSD), so that the filesystem can avoid those areas. I keep poorly framing my question... Im planning on going to Synology + Easystore route and Im trying to figure out whats a good CYA before putting the disks into the Synology in order to force bathtub curve issues to pop up sooner rather than later. Im trying to avoid popping in 4 drives straight out of the external enclosures into the NAS and then figuring out on my first backup that 1 or the 2 drives was toast right out the gate despite initializing and being formatted OK. Im also trying to avoid the equivalent of audiophile alignment crystals.

Settle on what you feel comfortable with, disks are going to betray no matter what you do. Also, I forgot to answer the first part about what you said earlier. 3- and 7-pass erasure existed because of an initial version of DOD 5220.22, which in the latest -M revision has been updated to no longer recommend a number of passes of rewritten data - original spec required a zero-pass, a one-pass, and a random-pass. I guess the idea that only one pass is enough is based on the lack of the standard no longer recommending a given number of passes, but I think it's more likely that DOD enforces cryptographic erasure on everything so they just don't care.

The other part to it is that any information system storing anything the DoD would actually care about requires the physical destruction of the media anyhow, not just an overwrite, before the device is released from the DoD's possession. Overwriting is only acceptable if the device is going to be re-used in the same environment, or if no classified data was ever stored on it. Otherwise you're talking incineration, destructive degaussing, or the good 'ol shredder above.
