12:33 🔗 icedice Any recommendations for a reliable 6TB HDD? I'll use in my desktop to store and access files, mostly videos.
12:34 🔗 icedice I'm thinking about getting a WD Black 6TB 256MB
12:34 🔗 icedice And I won't RAID the HDD
12:35 🔗 ivan best deal per GB right now is shucked 8TB WD My Book assuming stripping the warranty + applying tape over 3V lines is OK
12:36 🔗 icedice Also, how reliable are 6TB HDDs overall? I know that 1.5TB, 3TB, and 8+TB HDDs aren't as reliable as the other capacities.
12:36 🔗 icedice I ment internal HDD, not external
12:37 🔗 ivan external drives contain internal drives :-) :-)
12:37 🔗 ivan backblaze is the place that might have data but I don't think they bought many 6TB
12:37 🔗 ivan in general the annual failure rate is around 1% now
12:38 🔗 icedice BackBlaze stats is a joke
12:38 🔗 ivan there's an 6TB HGST He8 fwiw
12:39 🔗 ivan still available new as HGST Deskstar NAS
12:40 🔗 JAA 1.5 and 3 TB had some issues, yeah, but I haven't heard about systematic problems on 8+ TB drives. Any source on that?
12:41 🔗 icedice JAA: A hard drive technician on Overclock.net warned about 8+ TB drives: https://www.overclock.net/forum/20-hard-drives-storage/1634071-warning-about-8tb-drives-cautious-aware-higher-rate-failure-degraded-surfaces.html
12:41 🔗 icedice Why BlackBlaze's study sucks: http://www.tomshardware.co.uk/answers/id-2724690/seagate-hgst.html#r16270047
12:42 🔗 icedice They're using consumer hard drives in a server environment
12:42 🔗 JAA Yeah, Backblaze's data is pretty much useless.
12:42 🔗 ivan I have a lot of 8TB He8 drives and they're fine
12:42 🔗 icedice Of course HGST is going to dominate that
12:42 🔗 icedice ivan: How old are they?
12:42 🔗 ivan varies, mostly 1-1.5 years
12:43 🔗 ivan I test them a lot and have not seen bad blocks or whatever
12:43 🔗 icedice Ok. I'm mostly worried about the long term reliability, so it's too early to draw conclusions from that
12:44 🔗 icedice The only decent stats on hard drive reliability: https://www.hardware.fr/articles/962-6/disques-durs.html
12:45 🔗 ivan the "backblaze study sucks" comment you linked is clueless
12:45 🔗 ivan backblaze loads the drives with data and mostly leaves them alone
12:45 🔗 ivan also, complaining about stressing the drives too hard? wouldn't you want _more_ room for error in your own environment?
12:46 🔗 icedice They drives are in a high vibration environment
12:46 🔗 icedice Which they are not designed for
12:46 🔗 icedice Of course they're going to fail
12:46 🔗 icedice The server/NAS drives are the most reliable ones, but they don't have head parking
12:47 🔗 icedice And they have error recovery control
12:47 🔗 ivan backblaze is doing it wrong (internet commenter can assume they have excessive vibration?), and yet they fail 1% of the time?
12:47 🔗 ivan 2015 comment is motivated by the large number of 3TB Seagate failures and people wishfully hoping it wouldn't happen to them
12:48 🔗 Meroje warranty returns stats are worse than backblaze's imho
12:49 🔗 Meroje I returned none of my ST3000 because why would I want more of these ?
12:50 🔗 icedice A desktop environment and a server environment are completely different and can't be compared
12:50 🔗 ivan uh-huh
12:51 🔗 Meroje yet they get excellent numbers ?
12:52 🔗 ivan put a bunch of hard drives together into a crappy case at home and you've got vibration too
12:52 🔗 ivan do a lot of seeks for days, are you "server" now?
12:53 🔗 ivan anyway the modern drives seem to survive suboptimal conditions just fine
12:56 🔗 Meroje pretty sure most home cases have way more protection than backblaze chassis
12:56 🔗 ivan heh probably
12:58 🔗 Meroje https://www.backblaze.com/blog/wp-content/uploads/2016/04/blog-60-drives-ooh-aah.jpg
13:00 🔗 ivan boy are there going to be a lot of cheap hard drives available when flash finally eats everything
13:01 🔗 icedice https://www.tweaktown.com/articles/6028/dispelling-backblaze-s-hdd-reliability-myth-the-real-story-covered/index3.html
13:03 🔗 ivan you're linking to an article by a guy who has basically published Seagate press releases. what do you think the odds are of Seagate feeding him this as well?
13:04 🔗 Meroje the ST3000 incident was very real
13:04 🔗 ivan "HDD Reliability Myth - The Real Story Covered" sounds like something a PR drone would feed
13:04 🔗 icedice How am I supposed to know what the motivations of the writer of an article is?
13:05 🔗 icedice I just tried to find some article about vibration in BackBlaze's storage pods
13:05 🔗 icedice Anyway, for the record: Fuck Seagate
13:05 🔗 ivan well you can form good guesses with inference on the contents and author
13:05 🔗 ivan "This paints them in a very unforgiving light due to obvious chassis issues, with a misleading annual failure rate of 25.4% that would surely put Seagate out of business, if it were realistic."
13:05 🔗 icedice Never trusting that brand
13:07 🔗 JAA "Fuck Seagate" sounds like something someone would say who owned 10 ST3000DM001s, had them fail, and then swore to never, ever buy Seagate drives again.
13:07 🔗 JAA Modern Seagate drives are fine.
13:07 🔗 icedice I remember reading a post on Overclock.net from someone who's brother works at Seagate and the brother had warned him to "not buy Seagate right now", or something like that
13:07 🔗 icedice I don't trust Seagate
13:09 🔗 icedice 10.00% RMAs for Seagate Desktop HDD 6TB and 6.78% RMAs for Seagate Enterprise NAS HDD 6TB is not ok
13:09 🔗 JAA Neither do I. I don't trust any other company either. That's why I have drives from multiple brands and backups.
13:09 🔗 JAA Where are those numbers from?
13:10 🔗 icedice Yeah, I'm planning on getting a Glyph BlackBox Pro 6TB eventually to use for backups
13:10 🔗 icedice https://www.hardware.fr/articles/962-6/disques-durs.html
13:11 🔗 JAA Sample size of 100 to 200 drives. Okay then...
13:13 🔗 JAA In fact, all models for which they report a failure rate (ok, RMA rate) of over 3 % have such a small sample size. So yeah...
13:22 🔗 icedice I'd be all for trying HGST though, but I don't think they have head parking
13:23 🔗 icedice And I think all of their 6TB HDDs are sever/NAS drives, which means that they probably have error recovery control
13:27 🔗 JAA Yeah, I don't think there are any consumer drives from "HGST".
13:28 🔗 JAA I put quotes around that because HGST is just a brand of WD, several WD drives are actually rebranded HGST drives (e.g. WD Reds 8+ TB), and the HGST brand is being phased out.
13:38 🔗 ivan https://www.hgst.com/products/hard-drives mobile drives might be consumer enough
13:38 🔗 dashcloud has joined #archiveteam-ot
13:41 🔗 JAA Not 6 TB though.
13:48 🔗 icedice Yeah
13:48 🔗 icedice If I was using RAID I'd probably use HGST or WD Gold
13:48 🔗 icedice But since I'm not I'll probably go for a WD Black 6TB 256MB
13:49 🔗 icedice I was also considering Toshiba X300 6TB, but that one is apparently loud af
13:50 🔗 icedice https://www.youtube.com/watch?v=wlpyF8anf8A&t=1m29s
13:51 🔗 kiska So this is mostly anecdotal but I work with the NSW Department of Education and Training on casual basis. We purchased 12 Seagate Exos x12 12TB helium drives from Seagate themselves for a pilot test
13:51 🔗 kiska Within 6 months we had 7 of those 12 drives fail completely
13:52 🔗 ozlo__ has quit IRC (Quit: WeeChat 2.1)

21:35 🔗 ivan JAA: want to own grab-site? I'm bored of it
21:36 🔗 Flashfire Hey Ivan can grabsite be configured to upload to FOS or directly to the IA
21:38 🔗 ivan you can't upload your grab-site WARCs to FOS because I believe SketchCow wants ArchiveBot WARCs
21:38 🔗 ivan I can link you to an uploader for uploading to IA
21:40 🔗 ivan https://gist.github.com/ivan/079530350ac94851d581b55b1d372440 you may have to make changes, good luck
21:42 🔗 JAA ivan: I would like to merge grab-site with ArchiveBot eventually; that would make maintaining it essentially trivial since it would be a by-product of maintaining ArchiveBot (which likely won't go away for a while). As for taking grab-site over, I've never used it, so not sure how much sense that makes. (I always used plain wpull.)
21:43 🔗 ivan oh ok I didn't realize
21:44 🔗 ivan you just seemed like the only person doing some wpull programming
21:45 🔗 JAA Yeah, that's true.
21:45 🔗 JAA I should pick it up again. Haven't worked on it in over half a year.
21:45 🔗 JAA Getting it stable enough for a version 2.1.0 that is actually usable is the goal.
21:46 🔗 ivan grab-site does a bunch of stuff to avoid thinking about all the wpull arguments one might want to archive a website. if you have different opinions, maybe it can be salvaged and adapted to your preferences.
21:48 🔗 JAA I just found that I had to write custom code anyway in 99 % of the cases where I couldn't just throw it into ArchiveBot.
21:48 🔗 ivan it sounds like your archiving is of the sort where you actually try to archive it properly
21:48 🔗 ivan mine is the kind where I just toss in websites and hope for the best
21:49 🔗 JAA Heavily scripted sites, special ignores/filters that depend on the parent URL, stuff like that.
21:49 🔗 JAA Yeah, I try to grab it as close to the real traffic from a browser as feasible, essentially.
21:50 🔗 JAA Well, if I care enough. There are definitely cases where I just throw it into ArchiveBot and hope it works.
21:51 🔗 JAA If I care enough and have time for it.
