ReadyNAS Device Compatibility List

Hi again,

Nobody answered my question so I decided to proceed on my own and here are some experiences that might help somebody in making decisions concerning ReadyNAS Duo ....

First of all, I have ReadyNAS Duo 750 GB version, which came with pre-installed Seagate Barracuda 7200.11 disc. This particular disc is working just fine (although I am switching on and off my NAS every day) but because of the well known issues with Barracudas I decided to use Raid-X capability of this NAS in order to secure my data. It was quite clear to me that I will not go for another Seagate product.

So I decided to buy Western Digital WD1001FALS 1 TB disc. I installed it in ReadyNAS and immediately after switching on my NAS, it started to initialize the new disc. This process of initializing was finished after approx. 6,5 hours and then it started a synchronisation process. After 1 hour this process has been stopped with the message that some errors have been found on a disc and that they have been corrected. The initialisation started again. After several additional hours both processes finished without problems and NAS was running in Raid.

It is running already two days and I do not see any problems with it. It runs warmer as before (with only one disc inside Seagate was running at +37 grad. C and now it is 42 grad. C for Seagate and about 44 grad. C for WD) and produces marginally more noise. SMART attributes are telling me that there are some sporadic issues with WD (Spin up time) but it is not necessarily something connected with NAS ... ReadyNAS recognised that WD disc is larger than Barracuda and it is using only 750 GB (acctually 693 GB) of 1 TB available space.

So basically WD1001FALS is working with ReadyNAS Duo and it seems even to be a good pair for existing Seagate. On the other hand, two days are certainly not enough time to make any definitive conclusions. Therefore, please accept this post only as an experience - that is all I can say at the moment ...
