Travelstar DK23FB DK23FB-40 and DK23FB-60

These are the snapshots of a DK23FB-60 model:

The DK23FB hard disk drive family includes models with 20, 40 and 60GB capacities (we tested the latter two). They use platters of 30GB data density. The spindle rotation speed is 5,400rpm, the buffer size is 8MB, the average seek time is 13msec, and the latency equals 5.6msec. The drives are connected via the ATA-5 interface. The operational shock these drives can resist is 250g, non-operational is up to 800g.

Unfortunately, the manufacturer’s website doesn’t reveal any technological details about this family, which is Hitachi’s own development. However, the implemented technologies include: GMR heads, FDB motor, S.M.A.R.T., Embedded Sector Servo, Load/Unload Mechanism, ID-Less Format, ME2PRML Read Channel, CDR (Constant Density Recording), On-the-fly ECC Correction, Read-ahead Cache/Write Cache, Auto Read Reassign/Auto Write Reassign, Rotary Actuator, APM (Advanced Power Management).

The approximate price of the drive is $130 for a 40GB model and $185 for a 60GB one.
