Yev from Backblaze here w/ some insight -> Yes! They are expensive. We are looking to test some in our environment very soon, but may not have enough to (we want at least 45) to truly test them. Once they drop further in price and we can afford to drop them in some of our pods we'll be all over it!
- PascLeRasc 10y agoThanks Yev! I'm looking forward to those. I didn't realize they were that much more/TB than the 8TB guys.
- atYevP 10y agoYea still pretty pricey! Getting there though! We're waiting :D
- newman314 10y agoIs there a graph somewhere that shows the price/GB vs drive capacity that you would suggest? I've briefly tried looking for this in the past before but was never able to find a well maintained source.
- atYevP 10y agoIt's tough b/c we don't really keep track of prices after we buy them. Sometimes we go out and look up different drives on Amazon and add those in, but I don't remember if we keep track of exactly what you're trying to find - sorry! You could always look at the drive model and do a quick search and cross-check with our rates. Just know that your environment is different from ours so it might not be 1:1 :)
- jasode 10y agoSince you have many years of data, do you explicitly factor the observed the failure rate patterns of particular brands into cost models when buying drives? (E.g. more anticipated replacement cost factor when buying Seagate drives.) Or is the failure data purely for curiosity and not fed back into a spreadsheet? In other words, does every cost projection treat every brand with the same predefined anticipated failure rate regardless of brand?
- atYevP 10y ago> Since you have many years of data, do you explicitly factor the observed the failure rate patterns of particular brands into cost models when buying drives? Sometimes. We do take it in to account but if a hard drive that costs less but fails more comes around and the failure rate in our environment is within some "tolerance" we'll get that drive, even if we might see some more failure. So we do use the data to inform our purchasing department of the "future costs" of drives, but a good deal's a good deal :)
- cm2187 10y agoWhat about archive disks? You guys are storing people's backup data, I guess most of them are rarely access them if any. Or you wouldn't need to maintain all of the redundant data online all the time. Would it make sense to use cheap SMR disks like ST8000AS0002?
- atYevP 10y agoYou'd be surprised! We've restored over 20 Billion files at this point, folks are CONSTANTLY downloading one or two files, and because we encrypt everything before sending it up, when someone browses their tree we have to "find" all of those files, so we do have to have them more readily available!
- PascLeRasc 10y agoIf you're still willing to answer questions, what do you do with all the failed drives?
- atYevP 10y agoAlways! But sometimes I miss the comments b/c I don't an alert when someone responds to me, sorry for the delay, hope you see this. We recycle the drives once we take them out of circulation. First we secure wipe all the of them, and then they get recycled.
