Do not apply pressing force on the top cover (See Figure 1 on page 2).
Do not cover the breathing hole on the top cover (See Figure 2 on page 3).
Do not touch the interface connector pins and the surface of printed circuit board.
The drive can be easily damaged by shocks or ESD (Electric Static Discharge), so any damages applied
to the drive after taking out from shipping package and opening ESD protective bag are user's responsi-
bilities. .

3.3 Performance Characteristics
File performance is characterized by the following parameters:
Command Overhead
Mechanical Positioning
−Seek Time
−Latency
Data Transfer Speed
Buffering Operation
Note: All the above parameters contribute to a file performance. There are other parameters which con-
tribute to the performance on the actual system. This specification tries to define the essential file character-
istics, not the system throughput which is dependent on the system and the application.
The following table gives a typical value of each parameter. The detail descriptions are followed in the next
sections.
Figure 5. Performance Parameter
3.3.1 Command Processing
Command overhead time is defined as the total time from when the command is received by the drive to the
start of motion of the actuator.
3.3.2 Average Seek Time (Including Settling)
Figure 6. Mechanical Positioning Performance
'Typical' and 'Max' are given throughout the performance specification by;
Typical Average of the drive population tested at nominal environmental
and voltage conditions.
Max Maximum value measured on any one drive over the full range of the environmental and
voltage conditions. (See section on Environment and D.C. Power Requirements.)
Function Typical
Average Random Seek Time For Read 12 msec
Average Random Seek Time For Write 13 msec
Rotational Speed 4900 rpm
Power On To Ready 4.5 sec
Command Overhead 1.0 msec
Disk-Buffer Data Transfer 64.3 - 100.4 Mbit/sec
Buffer-Host Data Transfer 16.6 MB/sec (PIO Mode-4)
33.3 MB/sec (Ultra DMA Mode-2)
Command Type Typical Max
Read 12 msec 16 msec
Write 13 msec 17 msec
10 OEM Specifications of DYLA-2xxxx 2.5 inch HDD

The seek time is measured from the start of motion of the actuator to the start of a reliable read or write
operation. Reliable read or write implies that error correction/recovery is not employed to correct for arrival
problems. The Average Seek Time is measured as the weighted average of all possible seek combinations.
max
SUM (max + 1
Ä n) (Tn.in + Tn.out)
n=1
Weighted Average =
ÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ
(max + 1) (max)
Where:max = Maximum Seek Length
n = Seek Length(1tomax)
Tn.in = Inward measured seek time for a n track seek
Tn.out = Outward measured seek time for a n track seek
3.3.3 Single Track Seek Time
Figure 7. Single Track Seek Time
Single track seek is measured as the average of one (1) single track seek from every track in both directions
(inward and outward).
Function Typical Max
READ 4 msec 5.5 msec
Write 4 msec 6.5 msec
Drive Characteristics 11

3.3.4 Full Stroke Seek

Full stroke seek is measured as the average of 1000 full stroke seeks.
3.3.5 Average Latency
