i doubt there will be any advantage in new drives that will outperform the shipping costs… remember the hdd manufactures will sell new hdd locally so no logistics needed… sure bulk will save a lot… but each SNO or most SNO’s will want 1 or 2 maybe 3 hdd’s at a time.
then shipping becomes a large factor… however if you can buy bulk used drives for 33% or less prices, then the savings on large capacity drives become substantial…
sure there is a certain reliability concern, but really one gets 3 times the capacity, while only 1/3 would be essentially required for the lowest level of redundancy… and lets be fair… hdd’s can be very unreliable when one is having bad days.
ofc it’s all smooth sailing when everything is going well… but then a cable gets bumped, or one adds a hdd thats incompatible with the controller and all hell breaks loose.
been there already because i ran sas with sata in the same array… and yet zfs and it’s raidz kept me from loosing any data at all, my successrates suffered a bit… but ill take that over a dead node any day of the week… remember if you expect to run nodes for years like joe says, then you will have stuff wear out or simply get outdated…
is used drives a good idea… i duno… i’m running used drives… so far i got like 15 most from a reliable 2nd hand reseller, and the two or three drives that are bad, i think is mostly my fault.
i did also throw a couple of new drives into the mix, of the exact same models working on the exact same array… so will be interesting to see how that affects life span…
i think their capacity will become useless before they wear out, which is kinda why i bought them in the first place… the only reason i bought the new ones was because it was the only way i could get a matching model for the raid setup i wanted to do, because i don’t want to wear the disks out by using mismatched models in my raid arrays.
if new drives was an option for collective purchases i would without a doubt be up for that… but i don’t think the savings can get even remotely close to competing with local prices when considering the logistics.
i think my hdd reseller is current selling 14tb… so if we imagine buying those directly from a datacenter, doing some checking and such on them sorting out the bad ones, bought at lets say 25-33% of new costs… at 10$ pr tb just to make the pricing future compatible or current … been a while since i checked prices here.
so that leaves maybe 15% for logistics if we want to keep the SNO buy prices at 50% of new, maybe it can be cheaper i duno… 15% of a 14tb drive value is like 20$ roughly which doesn’t leave much room … but still it should be possible if we have some sort of logistical network across the globe and maybe sell in pairs which would ofc nearly half the logistics because a good deal of that would be handling and “recertification”
