-This product is a silicon disk drive interchangeable with a
2.5-inch IDE hard disks.
-This product provides exceptional robustness against environmental factors such as
vibration and shock, and is suitable for factory automation applications where high
reliability is required.
-Low consumption electric power.
-Exceptionally quiet operation, without the motor noise of a hard disk drive.
-According to the ware leveling function (flash life span stretching) ), the rewriting
average life spans are about the maximum 1.8 times in our company so far
compared with the product. (Differ depending on the use condition)

Write Access Mean Time Before Failure
The PC-SDD V Series incorporates a feature called wear leveling that extends the
lifetime of its drive by averaging the number of write accesses to individual disk
sectors. If an error occurs in an attempt to write to a sector (even during wear
leveling), the PC-SDD V Series uses an internally reserved spare sector to substitute
for that sector. If an error occurs during a write to a sector with all the spare sectors
used up, the sector is marked as a bad sector. The time interval that will elapse before
the bad sector appears is referred to as "write access mean time before failure." It is
calculated differently between when part of the drive is rewritten and when its entire
capacity is rewritten.
*About wear leveling: When the drive attempts to write to the same sectors to update
a file over and over again, this feature substitutes less frequently accessed sectors for
more frequently accessed ones (alternating the sectors to write to) to average the
number of write accesses to individual sectors, thereby providing longer lifetime.

Average number of writes before failure [No. of accesses] =
(1) When part of the drive is rewritten (total size of files to be updated < total SDD
capacity)
Average number of writes before failure [No. of accesses =
8
1.37 x 10 x -ln(1-
Note: The above formula is empirical.
Mean time before failure for write access [Hours]=
Ex. 1) If a 9.6-megabyte file is updated once per five minutes on the PC-SDD64V:
Average number of writes before failure [No. of accesses] = 22,047,597
Mean time before failure for write access [Hours] = 22,047,597/12 = 1,837,300
(= about 209 years)
Ex. 2) Three-megabyte swapping interval at which a lifespan of 10 years (87,600
hours) can be expected
Number of times swapping occurs per hour [No. of times/hour] =
60,682,175/87,600 = 692.7
Swapping interval [Seconds/No. of times] = 3600/692.7 = 5.19
A measured swapping interval of 5.19 seconds or more indicates a life
expectancy of at least 10 years.
(2) When the entire drive is rewritten at once (total size of files to be updated = total
SDD capacity)

Ex.) When a file of about 64 megabytes is updated once per five minutes [12 times an
hour] on the PC-SDD64V
Mean time before failure for write access [Hours] = 4,325,538/12
= 360,461 (= 41 years approx.)
