Disks for Synology NAS DS918+


I have a Synology NAS 918+ with 3TB WD Green drives. I have them running for some years.
2 disks are showing errors once and a while. I'm not sure if I should replace them all (quite costly, just bought the DS918+).

What disks would you advise to use (home usage, running virtual machine manager but could buy the SSD cache to optimize speed).
3TB is good enough, 4 TB is also an option. Budget is around 300 Euro.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Hi Jan,
In the WD product line, the Red drives are recommended for NAS devices. The 3TB one is £92 at Amazon UK (€104):

Since you need four drives for the 4-bay Synology DS918+, that would, unfortunately, put you about €116 over budget. There may be less expensive choices, but I have no personal experience with them, as I have put WD Red drives in all the NAS units for my clients and myself in the past several years. Regards, Joe
