Travelstar 40GN IC25N040ATCS04-0

The 40GN HDD family includes four models of 10, 20, 30 and 40GB storage capacities. We tested the last one. They use platters with 20GB data density. The spindle rotates 4,200 times a minute, and the cache buffer size is 2MB. The average seek time equals 12msec, and the latency is 7.1msec. The drives support ATA-5 interface. The shock parameters are the same as those of other drives from Hitachi: 200g operational and 800g non-operational shock resistance.

This HDD family uses the same pack of technologies from IBM as those implemented in the drives of the 80GN family, only Adaptive Formatting is missing in 40GN HDDs.

The price of this HDD is $125.
