This document describes the specifications and capabilities of the Intel® Solid-State
Drive 320 Series (Intel
®
SSD 320 Series).
The Intel SSD 320 Series delivers leading performance for Serial Advanced Technology
Attachment (SATA)-based computers in capacities up to 600 GB.
By combining Intel's leading 25nm NAND Flash Memory technolo gy with SATA 3Gb/s
interface support, the Intel SSD 320 Series delivers sequential read speeds of up to
270 MB/s and sequential write speeds of up to 220 MB/s.
The industry-standard 1.8-inch and 2.5-inch form factors enable interchangeability
with existing hard disk drives (HDDs) and native SATA HDD drop-in replacement with
the enhanced performance, reliability, ruggedness, and power savings offered by an
SSD.
As compared to standard SATA HDDs, the Intel SSD 320 Series offers these key
features:
• High I/O and throughput performance
•Low power
• Increased system responsiveness
• High reliability
• Enhanced ruggedness

LBA count shown represents total user storage capacity and will remain the same throughout the life of the drive.
The total usable capacity of the SSD may be less than the total physical capacity because a small portion of the capacity is
used for NAND flash management and maintenance purposes.

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.
Table 8.Reliability Specifications
ParameterValue
Uncorrectable Bit Error Rate (UBER)1 sector in 10
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)1,200,000 hours
Mean Time Between Failure is estimated based on Telcordia*
methodology and demonstrated through Reliability Demonstration
Test (RDT).
Power On/Off Cycles50,000 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 Rating5 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 Cycles250 insertion/removal cycles
The SSD supports up to 250 insertion/removal cycles on SATA/
power cable.

bits read, max
2.7Hot 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.
