22 TB of storage - ~500 $
the data stored on the fried disks - may be priceless
Yeah, the old adage to always make backups applies here, but I guess many people (me included) back up stuff by keeping duplicate copies on different drives, because it's very rare for two drives to fail at the same time. Except if your PSU decides to fry them, of course...
- arrowsmith 3y ago> 22 TB of storage - ~500 $ Side note, but damn, imagine telling someone in the 90s that storage would get this cheap. We've come a long way.
- Klaster_1 3y agoAbout twenty years ago, the admin of the local file sharing FTP bragged about getting a new 5TB server and invited me to take a look. Now my SFF PC has the same amount of storage like it's nothing. I wonder if in another 20 years we are going to see storage grow as much.
- Dylan16807 3y agoI doubt it. 83-93, disk prices dropped about 300x 93-03, about 1000x 03-13, about 20x 13-23, about 3x SSDs are catching up but they're not going much faster.
- iforgotpassword 3y agoAges ago had a raid5 with 4 drives. Two WD, a Seagate and a Toshiba. PSU blew up, took the two WDs with it. Game over. Still not sure if the WDs were more sensitive or just bad luck. This is obviously not statistically relevant in any way, I still wonder to this day...
- justsomehnguy 3y agoDepends on how they were connected, really. But WD always were quite demanding for the power quality and the amount, ie some drives could work with 11.75 while WD probably wouldn't. https://news.ycombinator.com/item?id=38834108 https://news.ycombinator.com/item?id=38834108
- Dylan16807 3y agoYou wrote that the bad reputation isn't from the drives themselves, but I consider any drive that turns voltage dips into corruption to be a problem. Especially on the time scale of milliseconds or larger, I expect it to self-monitor and either regulate the voltage or cancel the write attempt.
- justsomehnguy 3y ago5% on a 12v rail is 0.6v Chinesium PSU went way lower than 11v and... would you pay 5% more for the every HDD not to have a problem if your sub $20 PSU is sub $20 one? You quite literally wouldn't jave a problem with any HDD if you invested $20 more in your PSU.
- Dylan16807 3y agoI would pay more for the PSU, but I would also call the hard drive a delicate problem baby and give it a 3 out of 5 review.
- microtonal 3y agoOr the room with the drives burns down... or thunder strikes... or... Unless you are upstream-constrained or a data hoarder, just make offsite incremental backups. Preferably some redundant block storage.
- qeternity 3y agoIf your backups aren't physically diverse, they aren't backups. S3 Glacier Deep Archive is 99c/TB. Just ship it.
- fragmede 3y agoWatch out for restore costs though. It only costs $0.10 and $4/month to back up 1TiB, but $100-$350 to restore it, depending on how fast you want to restore. Still, $4/mo, or $88/month for 22TB is some peace of mind. https://www.arqbackup.com/aws-glacier-pricing.html https://www.arqbackup.com/aws-glacier-pricing.html
- beacon294 3y agoHaving paid restore costs due to user error in my home, it's worth it. I'm toying with offsite HDDs in the future, but still feel that reliability is inferior.
- tredre3 3y agoThe restore costs are absolutely worth it to most people, but it's still important to point out. As a teenager I would have been perfectly capable and willing to pay 5/month to backup all my stuff. But I wouldn't have been able to afford 100-150 to restore it. So not knowing about the restoration fees would have given me a false sense of security and it might have been disastrous.
- Zetobal 3y agoDMA made it a lot cheaper in the eu...
- beacon294 3y agoYes, well, $120/TB/decade if we convert it to HDD relevant units for cost comparison. About 12x the cost. Regardless, it has good reliability properties.
- karmakaze 3y agoThat's the first thing I thought. If he's concerned about the cost of replacement drives then it could have been much worse. Seeing that the post was in /r/DataHoarder I doubt it was priceless--though it could have taken a while to accumulate.
- Zetobal 3y agothere are 4tb sd cards now.... I paid like 200 bucks for an 8mb usb stick 20 something years ago.
