I recently bought a 4 bay Asustor AS5004T NAS which I used a old hard drive that I had laying around to get the system up and running initially. The S.M.A.R.T info for the single drive currently in my new 4 bay NAS is below:

Would you say the drive is about to immanently fail? It is to note the Reallocated sector count has gone up from 165 to 189 in just one day since I first installed the hard drive yesterday.

The drive comes from my old Segate Go-flex Home NAS that I got in 2009. The drive has been used lots over the years, and several months ago I had to perform a partition recovery on it in windows after the Go Flex stopped reading it.

I have in the mean time ordered a 6TB HGST Ultrastar 7K6000 Hard Drive for my new NAS.

I also have a 1TB 10'000RPM WD velociraptor hard drive in my Golfex at the moment, what I suppose I can also use with my new 4 bay NAS.

Your opinions and thoughts very much welcomed.

I understand. I just wanted to let you know what's the best case scenario, of course you are free to use whatever drives suit you best. I've said that because when going for a RAID configuration (depending on the setup you've chosen) with different models, sizes and performance, you'd get the performance based on the slower drives and size based on the smaller capacity drives as well.

Anyway, in the long run, you have a pretty good plan there. RAID 10 with 6TB drives sounds awesome. :)

Hey there, Elliott.

It really does look like the drive is going bad and it might be sooner rather than later having in mind the reallocated sector count keeps rising up. I'm really not 100% sure, but if the raw value shows the results in hexadecimal that means that those reallocated sectors are actually 393 (decimal value). But you'd have to check that from your NAS enclosure's manual in order to confirm it. Anyway, I wouldn't recommend that you keep using that drive for important data and if you have such data on it, please back it up right away.

On the other topic, why would you put different drives in a NAS enclosure? Do you plan on using it with the JBOD (just a bunch of drives/disks) setup? If not It's highly recommended that the drives are of the same make, capacity and model.

Hope that helps. Please let me know if you have any questions.

Why would I put different drives in a NAS enclosure?

Simply because I can't afford to fully populate it with my desired drive of choice at the moment and So I use what I have for multiple volumes in non RAID configurations.

This is my drive of choice: https://www.scan.co.uk/products/6tb-hgst-0f23001-ultrastar-7k6000-enterprise-sata-iii-6gb-s-128mb-cache-7200rpm-ncq

I have 3 more of them to get over the next couple of years, When I have all four, I will use them for 12TB of storage in RAID 10.
