Hi there GabeBB,
I want to start with that I don't really have any hands on experience with the particular drive.
It seems that it is a 7200 RPM one, with 64 MB of cache.
As for the comparison with WD Blue, I would say that you shouldn't really notice any performance difference, if we are talking about WD Blues that are up to 1 TB. Some of them, have 7200 RPM as well. Generally speaking, you won't notice any significant difference between two 7200 RPM drives.
The WD Blue models, that have storage space larger than 1 TB, would have 5400 RPM. In that case, you will get better transfer speeds with the drive you are currently looking at.
That was about the performance of the drives. The next thing would be reliability. The thing is that, you can't really know when your drive is about to fail. This is why, you should always back up your important data. It could last for years, or it could fail a couple of days after being installed. Warranty periods could be somehow indicative, so you can take a look at those. For WD Blue, the limited warranty period is 2 years.
