The power of the plate was neat: Up to 140 MB / sec write and nearly 160 MB / Sec reading are quite good, see picture above. The Caviar Green on the other hand does not get beyond 100 MB / sec, ok look also have another purpose. The values with ATTO Disk Benchmark measured under Windows Server 2012 Essentials in a HP Proliant MicroServer N40L on Raid.
Another picture on the other hand I won two straight-built computers, both with modern quad-core processors. There the plate as the stumbling block in the Windows rating is identified, even though it runs on SATA 6 Gb / s ports. As a mechanical drive is certainly not the Allerschnellste but inexpensive.
After nearly a year of operation 24/7 the plate developed a few bad sectors: annoying when it relates to the system disk in the server and just lay still a few important files on these sectors. While running the Microsoft Windows Home Server 2011, 1pk, 10u, x64, DSP, OEM, ENG by SFC / scannow untouched on, but it's still annoying.
A few weeks later, it was over: The plate lies no longer format and is now no longer as a nice paperweight.
Conclusion: Who does regular backups of his computer and looks at the price, it may risk. In any case I'll change, or did it already.
