2.6 Reliability
The Intel SSD 520 Series meets or exceeds SSD endurance and data retention
requirements as specified in the JESD218 specification.
Reliability specifications are listed in Tab le 8.
2.7 Hot Plug Support
Hot Plug insertion and removal is supported in the presence of a proper connector and
appropriate operation system, as described in the SATA 3.0 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.
Table 8. Reliability Specifications
Parameter Value
Uncorrectable Bit Error Rate (UBER)
< 1 sector per 1016 bits read
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 Failures (MTBF)
1,200,000 hours
Mean Time Between Failures is estimated based on Telcordia*
methodology and demonstrated through Reliability Demonstration
Test (RDT).
Minimum Useful Life/Endurance Rating
5 years
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
250 insertion/removal cycles
The SSD supports up to 250 insertion/removal cycles on SATA/
power cable.
