Hitachi offers their excellent DOS based HD Feature Tool that allows the user to view the specifics of the drive and change certain options such as S.M.A.R.T., AAM, Power Management, and read and write optimizations. Our drive arrived with Automatic Acoustic Management turned on and set to the quietest level. We were able to easily set different levels or turn off AAM altogether. We found in our limited acoustical testing there was not a real difference between the 128 and 256 setting. Performance was slightly affected with AAM implemented but we felt the benefits of having it turned on outweighed any performance impact.

The Hitachi Deskstar 7K1000 is the first 1TB drive to ship based upon manufacturer's specifications with a 750 GB offering scheduled for availability next quarter. Of course the actual capacity of the drive is 931.5 GB, but due to the way manufacturers report capacity the drive is considered to be a 1TB offering. This drive is also Hitachi's first 3.5-inch hard drive to use PMR technology. Additional 1TB versions for the Enterprise and DVR/Set-Top markets will be released later this year.

The 7K1000 features a 5-platter 10-head perpendicular magnetic recording design with rotational speeds at 7200rpm. The cache size has been increased to 32MB from the previous 16MB on the TK series. Hitachi includes their ramp load/unload, advanced low-power idle modes, and thermal-fly height control technologies. This drive series also supports Native Command Queuing and hot-swap capabilities. The Hitachi Deskstar 7K1000 drives ship with a three year warranty and additional specifications can be
