SEAGATE 8TB ARCHIVE DRIVE

RE: SEAGATE 8TB ARCHIVE DRIVE
Thanks for the information, Jason

Yes, before reading this article, here, I already had big troubles with this Seagate Archive HDDs with Synology.
FYI, Up to 2 of Seagate was fine, but after 2 more disks, the NAS had big troubles.
Synology indicated one of Segate failed. When I tested the failed disk, it was fine.
So I had to remove all the Seagate Archive HDDs and replaced with WD 8TB red.
After that, I also found out that Synology doesn't support this Seagate HDDs.

I still have 13 of Seagate Archive HDDs which are almost brand new one, and I have no idea what I have to do with them.

They basically have very large internal sector sizes, so that re-write operations require a large amount of data to be read from the disk, modified with the change, and then re-written back. Its more complicated than that.

This means these operations will have poor performance, and its not at all clear to me what their data integrity behaviors are.

This article discusses the SMR technology used by Archive drives

I am currently using 4 of WD 8TB Red, and it is working properly.

RE: SEAGATE 8TB ARCHIVE DRIVE
hi if all is working ok again for you with the WD drives, that is good.
there might be a way to return the archive drives if they are still essentially brand new (maybe if they cant refund they might do an exchange for non archive, seagate drives).... but, if you still have some that you appear to be stuck with, i think you can still use them for archival purposes though...

for example, if you have a stand-alone usb caddy which can support them (because some caddys can only support a certain amount of TB), then i am not aware of any thing that would prevent you from copying your drobo data, for example, and pasting it onto the archive drive. (that process should work ok, and could be a good way of backing up a lot of data), it is just the constant interactions and changes and rewrites that those drives are not best suited for, that they can be more exposed to in nas devices).

i need some more drives Smile (but im not sure if my icydock usb supports more than 2TB, which is the maximum i have tried with it so far) so that may be a challenge too Smile

(btw i have XP home SP2, a Drobo v1 with 2x 1TB/2x 1.5TB WD greens, & a bkp Drobo v2 with the same + a DroboShare: unused)
& a DroboS v2 with 3xWD15EADS &2x1TB in DDR mode on win7, & a drobo5D (all usb)
  • btw i did a sustained (write) operation for about 6 hours, and got 13.2MB / sec ...objection? "sustained" :)
    (16.7MB/s on a v2 & 47-96MB/s drobo-s)
