They do if you know where to look. I actually find deals on sas all the time. PM me with what you need and I'll keep my eyes open for it.Have SAS drives ever gone on sale?
Reading the thread about them figuring out which drive it is is kinda hilarious. Weighing the drives
Is the WD120EMFZ (12TB Easystore) a firmware-locked 14TB drive? Evidence and theory inside. : DataHoarder
Great info on the WD 2.5" drives, although I still think it would be nearly silly to put a usb interface on these if they were also producing them in an sata variant as those didn't sell either. I guess when someone cracks one open we'll see if a nice sata drive is in there or just another usb boarded drive.Yes well said @Evan. @Samir All 2.5" format WD external drives I'm aware of as of a few years back going forward have a USB only interface, so the USB port is actually integrated into the controller board on the drive itself. This is mainly why the WD 2.5" externals are "smaller" than the competition, e.g. Seagate. My dad does a lot of photography to stay active while retired, and he would buy the WD 2.5" Passport drives (the equivalent of these Easystore Portables) by the fistful. Inevitably they'd die and it was basically impossible for me to recover the data. I nudged him towards using the off-the-shelf NAS I bought him and he's been fine since then.
A lot of us who have tons of hard drives are data hoarders and want to mess around with storage arrays. I admit I have this compulsion, hah. I have most of my old media and audio collection ripped into a lossless or near-lossless digital format. Magnetic tape (VHS, Hi8, etc) and optical discs fail eventually due to degradation. For those who are wondering of the risk of failure of the disk array, the solution is not to place full trust into any single storage medium to begin with. I remember the days when WD was touting that it was nigh impossible for hard drives to fail (during the 60-120 GB days). I placed my trust in their word then and was predictably disappointed. The first clue was WD, then all the other manufacturers lowering the then standard warranty from 5 years to 3, and in some cases, 2 years I lost all my data from the late 1980s until the early 2000s, including my portrait and nature photography work. So it's important to at the very least have a second copy of the data somewhere. These days I have a second NAS replicating the data from the primary NAS, and an encrypted copy stored in the cloud.
Remember thought that a mirrored pair shouldn't be the only copy, so while it would be bad for a pair to fail, it shouldn't be catastrophic.I just worry about 2 drives same batch failing same time. I'd say exercise the @#$@#$ out of them. Use @BLinux 's drive burn in script thingie if you don't have your own.
yeah mirror makes sense for your requirements. I was considering 4x12 in Z2 after I replied but you didn't originally ask about it. For media etc. I'd do that and save my pennies to buy another set if I wanted a bit more throughput. 4xNxZ2 makes more sense to me to protect against failures in your use case.. Obs any 2 can fail and you get to go buy another two whether on sale or not and hope your rebuild finishes. 3 drives failing = very bad luck but if it was gonna happen I'd say it was gonna happen in the first 3 months FWIW. - just my opinion. I have personally experienced a 3 drive HW R6 failure - on my Birthday while I was playing blackjack in Vegas. Lost there. got home lost again. Nothing super critical. I also experienced a quad drive failure over a 2 hour period. They put in 2 replacement drives and then 2 more went during the rebuild. That was also 10 days after our RS kit was moved across the parking lot in DFW to their new data center. hmmm wonder what happened in the parking lot. but that is a whole 'nother story.
Never have I see SAS drives go on sale though sometimes they show up in CDW outlet but that is a crapshoot.
all my 8TB SAS3 drives were eBay purchases. I am almost finished getting that box (AIO) ready to go and then I get to move 40TB from my Synology DS2411/DX2411 to the new box. Then I need to buy some more drives and might do SATA 12's if they are onsale around Christmas - into the new backup box and then I can retire the SYNO and see if someone wants to buy it and the 3TB drives. I think about a third have 65K hours on them too.
LOL then I can think about cycling out the 8TB;s for the 12's... HAHAHAHA it never @#$@# ends. HAHAHAHA.
Yep, that's a pretty solid strategy. And like you said, once you add up all the copies of the data, it does start to get pricey. Then you start to think that some product from AWS that's got 99.9999999% uptime might be better for the price, and then realize that it would be just yet another backup medium.Living on the edge right here!
Personally I have the same data mirrored on two of my workstations, then there's the NAS which gets replicated to the backup NAS, then from there it's further replicated to the cloud in GSuite (or BackBlaze, pick the poison). There's also quite a few data hoarders who use old gear (e.g. Xeon v1/v2 with old smaller capacity disks) for their backup NAS, and only remotely turn it on to run the backup, then it's off again. In any case, this hobby ends up being quite expensive to maintain eventually
So for real off-site backup, it's pretty easy if you have parents or whatnot as you can easily setup an ipsec tunnel between the two sites that can be useful for a lot of things like monitoring them as they age (this was literally a godsend as I was able to watch the last moments of my mom's life earlier this year when I wasn't near them), remoting into their systems to keep them clean, etc. Then you simply have a replication nas setup at their place and just be sure to replicate regularly. And not only your stuff, but they can use it too and you can keep a copy of their stuff too in case of disaster. As everything moves to electronic mediums, these records start becoming more and more valuable.When I say don’t backup, still have a 2nd copy on disk like you, I meant real off site backup.
Was tempted to drop a small box maybe even just a Synology or something at my parents place.
End of the day while it may take time to get the lost bulk data back it’s like impacting if I didn’t have it and it’s always questionable if I need all of it anyway. I steam most media these days so stopped keeping terrabyes of movies and TV, just done stuff I can’t stream or may re-watch.
It's external drive deals like this that do take the sting out of off-site backups though. I have 2x 10tb drives from the last deal that I rotate regularly at a bank safety deposit box. They're not the only backup copies (actually just consolidated backups of backups), but they are a nice assurance. And it's cheap too unless you have truly large storage arrays--it was $350 for everything including the drives and the safety deposit box.that is exactly my plan for my backup AIO. its all onsite maybe someday I'll look at pushing it up. small steps. If a fire or flood or tornado destroys my house down I think I'm going to worry about other things first. that said my kit is insured. All hobbies end up being expensive when you take them to an extreme. I can afford two and kinda have three so I'm kinda sorta screwed.
I'm in the same boat with streaming today. I still have most of my back in the day super large mp3 collection on 2x 500gb ext drives that I haven't powered on in years now. :0 I do probably need to move that data into the fold if I want to keep it. Now that I think about it, I've got a lot of data like that to archive.I completely understand you there @Evan. I also mostly stream music/video nowadays, but as we are well aware stuff regularly gets discontinued/removed from the streaming services due to licensing issues. Hoarding high quality rips of media is just a compulsion I've had since the late 90s; always need some type of hobby to keep one's self out of trouble, that's what I told my neighbor the other day to tell his SO who is PO'd about his compulsion to buy beater cars to fix up, hah.
My backup NAS is at my parents house. It works out well enough as the replication jobs run in the background. The nice thing about a backup NAS is it can be older gear, though older folks like parents might be upset about noise or power usage. My backup NAS isn't particularly fast but it sips power so I'm fine there.
I've always really liked Synology DSM and recently QNAP QTS, but on the cost vs benefit front it's a hard proposition to me. I only got an off-the-shelf NAS for my dad since he's an older guy who isn't very techy and wanted to direct connect to the NAS via Thunderbolt from his laptop.
Depends on how you have it setup, what OS, etc, it took just over a week to transfer the 60 TB I have to an unraid array (averaged about 90MB/s IIRC).Is there a still 10% off coupon for best buy?
I just bought 14 2 TB drives from 8.5$ per TB, wish I didn't It seems like power savings will cover the difference.
Though, I am a little bit worried about the the disk throughput speeds as they are not much faster than before, it would take very long time to dump all the data from these disks.
You can make it there and then just poke along on the smaller roads on the way back vs the highway. And if you're in the bay area there's chargers everywhere.Whew! The three closest Best Buy stores are sold out. I would need to go 9 miles to another one, and the car only has 39 miles of electricity left. Not going to chance it today and save some money.
I think it's a matter of there being some sort of ceiling that's been hit when trying to read such tightly packed data on the platters. Before, the read speeds would increase as the density increased, but if there's a physics limit to how fast the data can be read/written, then just the size will increase and that's it....now you have a pool a magnitude bigger but pipe is same and not sure why the pipe is not getting bigger as it used to do in the past.
