Replacement Disk for RN314

Hi,

 

I have a RN314 with 4 x 2TB Seagate drives (ST2000VX000-1ES164) configured in RAID 5. These drives are end of life so what would be a good replacement for a disk with increasing errors on it?  I don't want to buy a new disk only to find it won't join the raid group due to different specs.

 

Thanks in advance!

 

L.

    Seeing that your existing disks are 7200RPM, any 7200RPM HDD suitable for NAS use should be a good choice.


    If you want to stick with 2 TB, then I'd suggest the WD2002FFSX (WDC Red Pro).  It is enterprise-class and purposed for NAS.  Seagate's equivalent line (Ironwolf Pro) doesn't have a 2 TB model - it starts at 4 TB.

    Agreed.  Les62 , if your storage needs are growing, then you should consider going with a bigger size.  Note you'd need two disks of the larger size to expand your storage.  But you could get one now, and the other later if budget requires that.  Both the Red Pro and Ironwolf Pro are good options.

  • There's a small risk that a different model 2TB disk could have a slightly smaller number of sectors and be rejected.
