Overview

This document describes the specifications and capabilities of the Intel Solid-State
®
1
Drive 520 Series (Intel SSD 520 Series) .
The Intel SSD 520 Series delivers leading performance for Serial Advanced Technology
Attachment (SATA)-based computers in capacities ranging up to 480 GB.
By combining Intel's leading 25nm NAND flash memory technology with SATA 6Gb/s
interface support, the Intel SSD 520 Series delivers sequential read speeds of up to
550 MB/s and sequential write speeds of up to 520 MB/s.
The industry-standard 2.5-inch form factor enables interchangeability with existing
hard disk drives (HDDs) and native SATA HDD drop-in replacement with the enhanced
performance, reliability, and ruggedness offered by an SSD.
As compared to standard SATA HDDs, Intel SSD 520 Series offers these key features:
• High I/O and throughput performance
• Increased system responsiveness
• High reliability
• Enhanced ruggedness
The Intel SSD 520 Series also offers additional key features such as:
• Advanced Encryption Standard (AES) 256-bit Encryption
AES 256-bit encryption is an industry standard in data security, providing a
hardware-based mechanism for encryption and decryption of user data. Utilizing a
256-bit encryption key, AES encryption — when combined with an ATA drive
password — helps protect user data.
• End-to-End Data Protection
End-to-end data protection helps protect data from being corrupted across the data
path by using cyclic redundancy check (CRC), parity, and error correction code
(ECC) checks in the data path from the host interface to the NAND, and back.
• Data Compression
Data compression helps improve performance and endurance by automatically
compressing information sent to the SSD so that less data has to be processed and
stored on the NAND. The amount of data that can be compressed depends on the
type of data.
1. The Intel SSD 520 Series is currently not validated for data center usage.

Notes: 1 GB = 1,000,000,000 bytes; 1 sector = 512 bytes.
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.
2.2
Performance
The data compression engine in the Intel SSD 520 Series controller optimizes
performance based on the data pattern of the workload.
This section provides both compressible and incompressible Input/Output Operations
Per Second (IOPS) and sustained sequential read and write bandwidth specifications.

Reliability
The Intel SSD 520 Series meets or exceeds SSD endurance and data retention
requirements as specified in the JESD218 specification.
Table 8.
Reliability Specifications
Parameter
Value
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.
16
< 1 sector per 10 bits read
Mean Time Between Failures (MTBF)
Mean Time Between Failures is estimated based on Telcordia*
methodology and demonstrated through Reliability Demonstration
Test (RDT).
1,200,000 hours
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 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.

The On/Off status of the Device Initiated

affect the number of hours reported. If DIPM
is turned On, the recorded value for
power-on hours does not include the time
that the device is in a "slumber" state. If
DIPM is turned Off, the recorded value for

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.

the host.

Timed Workload Media Wear
Measures the wear seen by the SSD (since
reset of the workload timer, attribute E4h),
as a percentage of the maximum rated
cycles.

Shows the percentage of I/O operations
that are read operations (since reset of the
workload timer, attribute E4h).

Available Reserved Space
This attribute reports the number of reserve
blocks remaining. The normalized value
begins at 100 (64h), which corresponds to
100 percent availability of the reserved
space. The threshold value for this attribute
is 10 percent availability.

Media Wearout Indicator
This attribute reports the number of cycles
the NAND media has undergone. The
normalized value declines linearly from 100
to 1 as the average erase cycle count
increases from 0 to the maximum rated
cycles.
Once the normalized value reaches 1, the
number will not decrease, although it is likely
that significant additional wear can be put
on the device.

SMART Logs
The Intel SSD 520 Series implements the following Log Addresses: 00h, 02h, 03h, 06h,
and 07h.
The Intel SSD 520 Series implements host vendor specific logs (addresses 80h-9Fh) as
read and write scratchpads, where the default value is zero (0). Intel SSD 520 Series
does not write any specific values to these logs unless directed by the host through the
appropriate commands.
The Intel SSD 520 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 520 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
