All disk models can fail prematurely (that's the reason we have warranties) and all disks will fail eventually (that's one of the reasons we always need backups of all important data).
I've been looking for a good drive to use with my NAS (TS-219P) and had almost decided to go with ST2000DM001 until I found this thread...
Well the most important message in this thread is that these disks should now be compatible, if they are updated with the latest firmware supplied by Seagate (must be done in a PC) and the NAS is updated to the 3.7.1 firmware.
My question is, are all the issues reported here related to RAID environments? Since i'm only interested in running jbod setup, are the issues discussed in this thread relevant for my setup?
I don't have any personal experience but I find it very hard to believe that the issues should be limited to RAID-configurations.
It may look like the problem is limited to RAID-configurations because the large majority use that with larger disks, like the one discussed in this thread. Also only with a redundant RAID-configuration is it possible to realize that the problems discussed here was what really happened and recover from such disk failure.
There really should be a better support from Qnap, helping us "stupid" beginners to find a supported drive to use.
It would be very dangerous for Qnap to make specific recommendations as to which disks to buy. The idea with a NAS is that you should be able to use different disks (within compatibility limits of course).
The forum is an excellent place to find buying recommendations.
Hitachi (you could look at HDS723020BLA642 for example) seems to generally have the least complaints form users here in the forum but all Seagate disks that can be found on the compatibility list (except of course the currently non-recommended ST2000DL003) should be okay. Avoid all WD desktop disks.
Enterprise disks from any manufacturer is preferable if you can afford them but they are much more expensive than desktop disks.
1. Decide on which disks on the market fit your storage capacity requirements and wallet.
2. Forget those that can't be found on the compatibility list.
3. Search the forum for other customer experiences (like it seems you did).
A compability list with hundreds of drives and > 15 "notes" to take into account makes it virtually impossible to make a "wise" choice...
Only a handful of the disks are marketed at the moment (but of course also older models have to be kept to have a complete list). The list is a compatibility list, not a buyers guide.
No, RAID has never ever been a replacement for backups. Without backups you will eventually lose data!
