Ok, I'll bite. Why won't a higher grade drive work thats rated for higher transfer rates and continuous use? The Scorpio blacks are used in high end SATA raid arrays running workload such as Oracle and VMWare. It's difficult for me to believe that old technology (the 622 was released 2-3 years ago) can't be upgraded with new technology that has higher specs than the old one.
I'm not arguing or doubting you, just curious.
I had a VMWare array that I bought 8 WD Green drives because I bought the Green 'thing' and the overall specs were close to the Black edition and wanted to save ten (literally the difference between the drives) bucks each. End result, VMWare ran like a pig in quicksand. I replaced them all with the same exact size of the Black edition and now the servers are blazing fast! Anyone want some 650G Green drives?
I have them stacked up in their original bags.
The Scorpio Blacks are what EMC and Netapp use in their SAN devices after they run their certification process on them. I've been told that only 4% don't make it for one reason or the other (outside heat specs, mean time flush cache and park, etc). At work I have EMC SANS that have SAS and SATA DAE's. All the 7200 RPM SATA DAE's use the WD drives. I must admit though, that I've yet to figure out how their testing and certification makes a $100 drive a $1800 drive? Marketing, go figure.
Ok.. I'll give you that the ones we use at work are the 3.5" version but EMC, Equalogic and Netapp are all coming out with higher density versions of their SAN's with the 2.5" drives.
