Western Digital 2 TB RE4-GP SATA 3 Gb/s Intellipower 64 MB Cache Bulk/OEM Enterprise Hard Drive - WD2002FYPS

**Update 2/10/2011** Another RMA for all three drives. I just spent 2 weeks rebuilding my RAID, restoring and re-backing up my data after the drives corrupted all my data. This is the 4th set of drives for me. They are upgrading them to the 2003 version that has the set 72000RPM speed to eliminate the issue with drive timing issues.

**Update 1/10/2010** Western Digital swapped out my old drives for the newer version which seem to handle the read/writes and spin rates much better. I had to rebuild the RAID for each drive replacement and copy my data over for backup (about 1.5TB including some large video files exceeding 15GB).

I purchased five of these 2 TB Western Digital Data Center Rated Hard Drives for a new Synology DS509+ Network Attached Storage Server I bought for my small business. After about two weeks up and running, so far so good. They are extremely quiet, and generate just a small amount of heat. The variable speed capability works great. When there is no read-write activity, the drives are very quiet and consume less energy. When read-write activity is high, they are only marginally noisier. The read-write speed, at least from a subjective viewpoint, when doing backups is outstanding.

These drives have performed flawlessly in a NetGear ReadyNAS Pro. It is necessary for the NAS's firmware to disable the 'green' function of these drives to prevent repetitive head parking (Load Cycle Count). Alternatively WD provides a patch called WDidle3 to use if your NAS's firmware isn't up to date. I was an early adopter to using this drive in a RAID NAS, and will buy these drives again.
