Internal Laptop HDD Hitachi Travelstar DK23EA-40

The Hitachi Travelstar DK23EA-40 is a 2.5-inch 40GB hard drive with an ATA-5 (IDE/PATA) interface, a 4200 RPM spindle and a 2MB buffer in a 9.5 mm high package. This drive is used and has been tested in our lab.

It is mainly intended for repairing and reviving older laptops with an IDE connection, industrial devices and legacy systems that need a 2.5-inch IDE drive, when replacing the whole device makes no sense.

The drive uses GMR heads, an ME2PRML read channel, a Fluid Dynamic Bearing motor for quiet operation and shock resistance, a shock sensor and S.M.A.R.T. support. It withstands 250G of shock in operation and 800G when switched off.
