Fastest Ever! Western Digital RE4 2TB Enterprise Grade 'RAID Edition' hard drive w/ 64MB Cache
Don’t confuse this drive with the slightly lower-priced RE4 “Green Power” version, which might not match its performance (not tested).
Where to buy
The main downside to the RE4 is the price, which is more than double that of the non-enterprise Hitachi 7K200, though nearly the same price as the Hitachi UltraStar A7K200. Price conscious users will find the Hitachi 7K2000 an outstanding value and performer. But those looking for top performance will find the RE4 very attractive.
Read the details in my review of the Western Digital RE4 2TB hard drive.
The performance level is high enough that the speed of only a 2-drive RAID-0 stripe should suffice for all but the most demanding users. This drive would be an excellent choice for the MPG Pro Workstation for users seeking the highest possible hard drive performance.
The RE4 is also an enterprise grade drive, which implies higher reliability. That reliability, along with apparent best-in-class performance means that this is a great choice for demanding users.
