Hitachi Brings 400GB to Desktops with the Deskstar 7K400by Anand Lal Shimpi on July 10, 2004 12:00 AM EST

What to do with 400GB?Thanks to the extra platters, the 7K400 actually feels a little heavier than other 2 or 3 platter drives. It's nothing to worry about, but just an interesting thing to point out.
The drive itself looks much like the older IBM drives, but thankfully, it seems as if the old reliability issues have not been carried over to the new Deskstar line.
With a street price of around $450, the Hitachi Deskstar 7K400 is one expensive animal, but Hitachi has priced the drive about where 2 x 200GB drives would fall, so there's no cost benefit to going with two smaller drives vs. one 7K400 (or vice versa).
With 400GB of storage, the 7K400 offers a great place to store application installation files, disk images, movies, MP3s, games as well as meet any other archival needs that you may have. The thing to keep in mind with a 400GB drive is that the more you fill it , the more you have to worry about backing up. The old saying - the bigger they are, the harder they fall - applies quite well to the 7K400; don't buy a 400GB hard drive without having a good way of backing up that data.
Hard Drive Specification Comparison
|Hitachi Deskstar 7K400||Maxtor MaXLine III||Seagate Barracuda 7200.8||Western Digital Raptor II|
|Number of Platters||5||3||3||2|
|Average Seek Time||8.5 ms||9.3 ms||8 ms||4.5 ms|

|Spindle Speed||7200 RPM||7200 RPM||7200 RPM||10,000 RPM|

As you can see by the basic specification comparison, the 7K400 will look much older once the Maxtor MaXLine III and Seagate Barracuda 7200.8 hit the streets next quarter. But for the time being, the 7K400's specifications are competitive with other present-day 7200RPM desktop drives.
