B.2 Preventive drive replacement
When installed in the instrument, the drive is the "data center" of the instrument. It con-
tains all of the programs and recorded data. The CPU may be the "brain" of the system,
but the drive is its memory and personality; it is what makes the instrument what it is.
Do not to exceed the drives warranty period.
Contact HBM service for more details.
B.2.1 Hard disk drive
Thereliableservicelifeofatypicalharddiskdriveisaroundthreetoveyears.
Some drives work for a decade or longer, but every year that passes after three years
increases the chances of a failure.
If the instrument uses a hard disk drive, HBM therefore advises replacing it at least
every two years to prevent loss of data or inactivity of the instrument.
This recommendation is based on 24/7 use of the instrument at full drive write speeds.
Reduced use of the instruments drive allows for a longer replacement period.
B.2.2 Solid State Drive (SSD)
Solid State Drives have no mechanical parts that can fail. However, each block of data
onaSolidStateDrivecanonlybeerasedandwrittenadenednumberoftimesbefore
the data block fails. The Solid State Drive manages this limitation so that drives can
last for many years with normal use. Very intensive use of the Solid State Drive to
record and store new data will shorten the drive's life expectancy.
