SSDs and HDDs (including NL-SAS, SAS, and SATA) cannot be preserved for a long time in
the power-off state. Data may be lost or faults may occur if the preservation duration exceeds
the specified maximum duration. When drives are preserved under the storage temperature
and humidity specified in the preceding table, the following preservation duration is
recommended:
● Maximum preservation duration of SSDs:
● 12 months in power-off state without data stored
● 3 months in power-off state with data stored
● Maximum preservation duration of HDDs:
● 6 months in unpacked/packed and powered-off state
● The maximum preservation duration is determined according to the preservation
specifications provided by drive vendors. For details, see the manuals provided by drive
vendors.
