Tbh I've preferred the WD Black series over Blue. They're more reliable, although somewhat noisier if that is a consideration for you.
I've been buying WD 7200RPM drives for almost 20 years, and have never had one fail, so never had to test the warranty. I have had a few used daily for over 10 years that had to be retired (needed larger drives).
I have used many of the 80GB drives, but eventually replaced them with 320GB versions, and I'm still using 3 of those in another system. The 1TB Blue that I have been using for the past three years in my DAW still reports perfect health in the SMART info and disk self test. It is fast, quiet, and reliable.
It appears that 500GB is the smallest capacity WD desktop drive currently available.
I noticed recently that WD has removed all 7200 RPM drives EXCEPT the 500 GB & 1TB model from the Blue label, and they are only available in the Black version for 2TB and up. The 1TB only costs $2 more than the 500GB.
So if you need more than 1TB capacity in a 7200 RPM HDD, you are stuck with Black (with a higher price point).
