1. Introduction
(2) mSATA,Half-Slim SSD ---This model uses a mSATA or Half-Slim SSD in the OS storage area.
The NandFlash can be rewritten 60,000 times or more for the mSATA drive and
3,000 times or more for the Half-Slim SSD drive.
As a reference value, the rewritable lifetime can be determined by the following
calculation.
Rewritable lifetime (number of times) = ((capacity [MB] / management block size
[MB]) × 60,000 times) / (number of management blocks rewritten each time)
Example: If a 4MB file is created on an 8GB mSATA drive and is rewritten once
every 10 seconds:
Rewritable lifetime = ((8,012/2) × 60,000)) / 2 = 120,180,000 (number of times)
Lifetime = 120,180,000 / ((60/10) × 60 × 24 × 365)≒ 38 (year)
Example: If a 4MB file is created on an 32GB Half-Slim SSD drive and is
rewritten once every 10 seconds:
Rewritable lifetime = ((30,533/2) × 3,000)) / 2 = 22,899,750 (number of times)
Lifetime = 22,899,750 / ((60/10) × 60 × 24 × 365)≒7 (year)
(3) AC adapter---The "PWA-84AWD1" optional product is included in the package. For details on
the lifetime, see the "PWA-84AWD1" user's manual, which can be downloaded from
the CONTEC website.
* Replacement of expendables is handled as a repair (there will be a charge).
* Component life is not guaranteed value but only referential value.
