HDD SATA S.M.A.R.T Test fail of WD red in DS412+

[femo]

hello guys,

i have a DS412+ - DSM 5.0-4528
since a couple of days, i have 2 out of my 4 disks producing errors on the S.M.A.R.T Test.

i have 4 x WD30EFRX-68AX9N0 3Tb set up with SHR with data protection of 1 disk fault-tolerance
Total capacity 8.05Tb

now one disk is showing bad sektors and the other one it just shows failed SMART Test.

what should be my next steps ? i guess i should exchange the disks ASAP....correct ?
shall i take the same model WD red 3 Tb again ? are there better one's ?

for example the WD3001FFSX or WD3000FYYZ ??

as to changing.....theoretically i could just pull out one of the faulty disks and slide in a fresh one
and the system will rebuild....correct ?

looking forward to your ideas on this.

Yes, you should change asap. The same (or similar) drive if possible (the drive performance should be almost equal in a RAID - if there are (too large) differences you maybe get error messages about degraded RAID).

thanks frogman,

which HD is recommandable ? cause i am pretty disappointed that 2 disks are having problems after less than 2 years .....

WDRed are pretty good - you can buy this model promptly. Another good one is the HGST/Hitachi Deskstar-series.

ok, thanks a lot froggy
i ordered 2 of the red 'pro' series in 3Tb lets see how they will do

and what do u think ?
can i just pull the faulty one, let the system automatically rebuild and than pull the second one and
repeat ?

Yes, of course - but it's much more relaxing if you have a backup
