Overview
®
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 technology 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

Reliability
The Intel SSD 320 Series meets or exceeds SSD endurance and data retention
requirements as specified in the JESD218 specification.
Table 8.
Reliability Specifications
Parameter
Value
16
Uncorrectable Bit Error Rate (UBER)
1 sector in 10 bits read, max
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
50,000 cycles
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
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.
2.7
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.

The raw value shows the count of errors
that could not be recovered using Error
Correction Code (ECC).

Power-Off Retract Count (Unsafe Shutdown
Count)
The raw value of this attribute reports the
cumulative number of unsafe (unclean)
shutdown events over the life of the device.
An unsafe shutdown occurs whenever the
device is powered off without STANDBY
IMMEDIATE being the last command.

SMART Logs
The Intel SSD 320 Series implements the following Log Addresses: 00h, 02h, 03h, 06h,
and 07h.
The Intel SSD 320 Series implements host vendor specific logs (addresses 80h-9Fh) as
read and write scratchpads, where the default value is zero (0). Intel SSD 320 Series
does not write any specific values to these logs unless directed by the host through the
appropriate commands.
The Intel SSD 320 Series also implements a device vendor specific log at address A9h
as a read-only log area with a default value of zero (0).
5.5
Device Statistics
In addition to the SMART attribute structure, statistics pertaining to the operation and
health of the Intel SSD 320 Series can be reported to the host on request through the
Device Statistics log as defined in the ATA specification.
The Device Statistics log is a read-only GPL/SMART log located at read log address
0x04 and is accessible using READ LOG EXT, READ LOG DMA EXT or SMART READ LOG
commands.

SMART Command Transport (SCT)
With SMART Command Transport (SCT), a host can send commands and data to an
SSD and receive status and data from an SSD using standard write/read commands to
manipulate two SMART Logs:
• Log Address E0h ("SCT Command/Status") — used to send commands and retrieve
status
• Log Address E1h ("SCT Data Transfer") — used to transport data
The Intel SSD 320 Series supports the following standard SCT actions:
• Write Same — Intel SSD 320 Series implements this action code as described in the
ATA specification.
• Error Recovery Control — Intel SSD 320 Series accepts this action code, and will
store and return error-recovery time limit values.
• Feature Control - Intel SSD 320 Series supports feature code 0001h (write cache)
and feature code 0002h (write cache reordering).
