Reliability

The Intel SSD 320 Series meets or exceeds SSD endurance and data retention
requirements as specified in the JESD218 specification.
Reliability specifications are listed in
Table 8. Reliability Specifications
Parameter
Uncorrectable Bit Error Rate (UBER)
Uncorrectable bit error rate will not exceed one sector in the
specified number of bits read. In the unlikely event of a
nonrecoverable read error, the SSD will report it as a read failure to
the host; the sector in error is considered corrupt and is not
returned to the host.
Mean Time Between Failure (MTBF)
Mean Time Between Failure is estimated based on Telcordia*
methodology and demonstrated through Reliability Demonstration
Test (RDT).
Power On/Off Cycles
Power On/Off Cycles is defined as power being removed from the
SSD and then restored. Most host systems remove power from the
SSD when entering suspend and hibernate as well as on a system
shutdown.
Minimum Useful Life/Endurance Rating
The SSD will have a minimum of five years of useful life under
typical client workloads with up to 20 GB of host writes per day.
Insertion Cycles
The SSD supports up to 250 insertion/removal cycles on SATA/
power cable.

Hot Plug Support

Hot Plug insertion and removal is supported in the presence of a proper connector and
appropriate operating system (OS), as described in the SATA 2.6 specification.
This product supports asynchronous signal recovery and issues an unsolicited COMINIT
when first mated with a powered connector to guarantee reliable detection by a host
system without hardware device detection.
