For detail condition, see Section 4.1.
(*1)
Vibration applied to the drive is measured at near the mounting screw hole on the frame as much
(*2)
as possible.
At random seek write/read and default on retry setting with log sweep vibration.
(*3)
At power-off state after installation
(*4)
Vibration displacement should be less than 2.5 mm.
Input voltages are specified at the HDD connector side during HDD Idle state.
(*5)
Operating currents are values under random W/R operation of full partition at about 220 IOPS.
(*6)
High frequency noise (over 20 MHz) is less than 100 mVp-p.

Error rate

Errors detected during initialization and replaced by alternate block assignments are not included
in the error rate. Data blocks to be accessed should be distributed over the disk equally.
(1) Unrecoverable error rate
Errors which cannot be recovered within 63 retries and ECC correction should not exceed 10 per
16
10 bits read.
(2) Positioning error rate
Positioning errors which can be recovered by one retry should be 10 or less per 10
