ReadyNAS NV PSU failure

I’ve never had a problem with my 2 original ReadyNAS 600 devices. The ReadyNAS NV, though, well, it’s not been smooth. I’ve had a couple of drive failures, had to perform a service action and last week the Power Supply failed, with a smoky smell!

Infrant, actually now Netgear, support were great. I’d read a bit of background to the problem on the forums, and they shipped a replacement out the same day. I replaced it today, and it’s still working!

Another disk failure.

“Disk fail event occurred on SATA channel 3. Please replace the failed disk as soon as possible”

The second disk to fail in 5 months – another HDS HDS724040KLSA80 7K400 GB Deskstar. I’m replacing it with a Seagate Barracuda ES ST3750640NS 750GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive (from NewEgg).

New Hard Drive

As I’ve lost a drive in one of my NAS arrays, I need to replace it. The ReadyNAS can handle different types of drive, but will only perform at the capacity and speed of the smallest and slowest drive in the set. As I have 3 good HDS 400 GB drives and 400 GB is a little on the small side, I thought I’d do a rolling upgrade by putting in a bigger drive. So what’s the largest capacity SATA drive available today? It’s the Seagate Barracuda 750 GB one. So, after checking the HCL at Infrant to ensure it’d work with the ReadyNAS, I noticed that there are a couple of models to choose from – even after ruling out the 8 MB cache in favor of the 16 MB version.

Checking out my favorite store for harddrives, ZipZoomFly, I noticed that there’s a difference in price between the 2 models I’m interested in, the ST3750640AS and the ST3750640NS. Now as the Seagate site is down at the moment (I hope that’s not prophecy), I had a quick look at the Hard OCP Forum before heading to the Infrant Forums where I found a good thread explaining the differences.

Basically the NS version handles the additional heat and vibration better than the AS version, and it’s the one Seagate recommends for running in NAS/RAID configurations. So I got one for $320 and it should arrive in a couple of days.

We love RAID5

We like the ReadyNAS too! It was a HDS HDS724040KLSA80 7K400 GB Deskstar that failed.
