NAS RAID, What to Do to Replace One, Failed 500GB HDD?

Geekomatic on 10/03/2015 - 18:11

Hi all,

I have a Linksys Mediahub, which has performed fine for a few years now. Recently, one drive failed. I can still access the remaing drive, but need to replace the other asap. Except, there aren't any other 500GB's I can find (near me), except for WD Blue. The one in this is the WD green (which "was" WD's NAS recommended drive until they decided to start the new, pricier RED series).

So, question is: what to use?

WD 500GB Blue (not a NAS drive)

or:

WD Red 1TB & waste 500GB- as the RAID will only use 500GB of it…

Ideas?

Ta!

    WD 500GB Blue.. it will be cheaper and wont have a negative effect on the raid

    I'm using a WD green on my Synology NAS. No issues at all. Go for WD Blue.

    Anything of the same size or greater will work, albeit perhaps with some waste.

    Thanks all!

    I was going that way, just wondered thoughts & if I was stupid to drop a blue in!

    Cheers! ;)

    I would be inclined to get the biggest drive this will take, which is 2TB as far as I can determine, rather than a drive that matches the existing one. The reason is that the other drive will probably fail as well, and when it does you can replace it with the same size and get a bigger mirrored array (4 times larger).

    eg http://community.linksys.com/t5/Media-Hub/replace-harddisk-w…

    A 500GB blue is around $55 to $60

    A 2TB green is around $90 to $100

    You'll probably find it easier to source 2TB than 500GB as well.

      Yeah, that's what I did with a NAS. Only problem was I had to copy the content off it to migrate to a larger disk as the only way to get it to use larger capacity disks is to recreate the array.

        Link given suggests it will work OK with this RAID1 type system. And hell, it's only 500GB.

        • retiredfeline on 11/03/2015 - 10:15

          Yeah, but it might be important 500GB of stuff. I would have made a backup copy even if the expansion had been possible in situ in my case.

    remember to BACKUP the data to a 3rd HDD before recover the RAID, that is the rule of thumb.

      Ditto, RAID is redundant, not a backup (of itself).
