better than value of how long without a restart your NAS has been in operation
is a proof of what is the oldest disk in your NAS based on Power On Hours SMART info?
then you can replace:
or simple with HDSentinel:
the just copy and paste result from this command:
Model Family: Seagate Constellation CS
Device Model: ST1000NC001-1DY162
Serial Number: Z1D5PAPR
User Capacity: 1,000,204,886,016 bytes [1.00 TB]
Rotation Rate: 7200 rpm
Form Factor: 3.5 inches
For Seagate you can check a manufactured date:
- Seagate disks use a 4 or 5 digit numeric code (called a Date Code)
The DATE format is really simple - YYWD or YYWWD where Y (year), W (week number), D (day number). Then you need use simple math for deducting of the exact manufacture date:
Seagate uses a fiscal year for their calculation which starts on the first Saturday in July = week 1 in the DATE. Counting of the days of the week running from Saturday = day 1
Then for the DATE: 13395 is the manufacture date calculated by this way (simple XLS math):
13 = YY = 2013
39 = WW = 39 week from 1st Saturday of July 2013 .... 1st Saturday = July 6th 2013
5 = D = Wednesday
The manufacture date was: April 10th 2014
When you have idea when was the disk purchased, then use simple math:
Today Date - Date of purchase = Number of days in your ownership
% of the disk utilization = Value from Power on Hours(in days) / Number of days in your ownership
it's about how is your disk really utilized.
I'm just curious about the oldest drive from you.

you will get value in hourssmartctl --all /dev/sda | grep Power_On_Hours | cut -d "-" -f2 | tr -d "[:blank:]"
then you can replace:
by /dev/sdb, /dev/sdc, .../dev/sda
or simple with HDSentinel:
./hdsentinel | grep Power
the just copy and paste result from this command:
like this:smartctl -i /dev/sda
