[Leaplist] Seagate 400Gb IDE ATA100 drive for $99.99

["pberry2" at cfl.rr.com]

Surfing prices, found that http://computergate.com has the Seagate 400Gb 
IDE ATA100 drive for $99.99 plus shipping...

With seek time of 8ms.  It seems to have three platters.

Is this a "good thing"? 

As far as price, this item seems to come up everywhere else in my google 
search at a minimum price of $125.00 plus shipping.
