Mixing seagates drives

[Jriker1]

I currently have 5 Seagate ST33000651AS drives in a DS2411+. Can't get them anymore since the hard drive industry is finally coming back. Now they have the Seagate ST3000DM001 which I guess replaces it. Hear questionable reviews. Anyway I am using 3TB drives. Can these two models work together in RAID 5 or am I stuck with what I have or have to replace them all? I want to add one more 3TB drive t this point.

Thanks.

Hi

The disk's are on the compatibility list, so they will work fine with your old disk's.

Thanks for the reply. So from a pure raid perspective this isn't an issue? What about the whole belief that all drives need to be the same with the same number of platters, spinels, speed, etc? Especially with raid?

Thanks

Hi

It depends on what you are expecting of your disk's

If this is an issuer, then I would not use desktop disk's but only Enterprise disk's, that is the only disk's that you are guaranteed that RAID work's.

But when that is said, you can use different disk's both in size ,model and brand, and still get it to work fine in RAID.

But OFC the more you mixed the disk's the bigger is the possibility for errors.
