2.7 Temperature Sensor
The Intel® SSD DC S3520 Series has an internal temperature sensor with an accuracy of +/-2C over a range of -20C to
+80C which can be monitored using two SMART attributes: Airflow Temperature (BEh) and Device Internal
Temperature (C2h). Both attributes report the same temperature value. For more information on supported SMART
attributes, see “SMART Attributes” on page 18.
2.8 Power Loss Capacitor Test
The Intel® SSD DC S3520 Series supports testing of the power loss capacitor, which can be monitored using the
following SMART attribute: (175, AFh).
2.9 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 3.2 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.
User Data is protected from planned or unplanned power loss by the Enhanced Power Management technology on
the Intel® SSD DC S3520 Series.
2.10 Self-Encrypting Drive (SED)
The Intel® SSD DC S3520 Series is a Self-Encrypting Drive (SED), meaning it supports hardware-based full-disk
encryption (FDE). AES-256 based encryption is built into the drive and is transparent to the user. Authentication on
power-up is done by way of the BIOS or ATA Security Feature Set.

5.4.2 Timed Workload Endurance Indicators
Timed Workload Media Wear Indicator — ID E2h
This attribute tracks the drive wear seen by the device during the last wear timer loop, as a
percentage of the maximum rated cycles. This value should be divided by 1024 to get the
percentage.
For example: if the raw value is 4455, the percentage is 4455/1024 = 4.35%. The raw value is held
at FFFFh until the wear timer (attribute E4h) reaches 60 (minutes) after a SMART EXECUTE OFFLINE
IMMEDIATE (B0h/D4h) subcommand 40h to the SSD. The normalized value is always set to 100 and
should be ignored.
Timed Workload Host Reads Percentage — ID E3h
This attribute shows the percentage of I/O operations that are read operations during the last
workload timer loop. The raw value tracks this percentage and is held at FFFFh until the workload
timer (attribute E4h) reaches 60 (minutes). The normalized value is always set to 100 and should be
ignored.
Intel® Solid State Drive DC S3520 Series
Workload Timer — ID E4h
This attribute is used to measure the time elapsed during the current workload. The attribute is reset when a SMART EXECUTE OFFLINE IMMEDIATE (D4h) subcommand 40h is issued to the drive.
The raw value tracks the time in minutes and has a maximum value of 2
32
= 4,294,967,296 minutes
(8,171 years). The normalized value is always set to 100 and should be ignored.
User Notes
• Sending a SMART EXECUTE OFFLINE IMMEDIATE (B0h/D4h) subcommand 40h to the SSD
resets and starts all three attributes (Media Wear Indicator, Attribute E2h, Host Reads
Percentage, Attribute E3h, and the Workload timer, Attribute E4h to FFFFh.
• The Attribute raw values are held at FFFFh until the Workload timer (Attribute E4h) reaches
a total of 60 (minutes) of power on time. After 60 minutes, the Timed Workload data is
made available.
• After the Workload timer (E4h) reaches 60 (minutes), the Timed Workload data is saved
every minute so only 59 seconds of data is lost if power is removed without receiving ATA
STANDBY IMMEDIATE. Accumulated data is not reset due to power loss.
• Upon power up, the attributes hold a snapshot of their last saved values for 59 seconds
and live data is available after 60 seconds, once the initial one hour interval is completed.
Example Use Cases
The Timed Workload Endurance attributes described in this section are intended to be used to
measure the amount of media wear that the drive is subjected to during a timed workload.
Ideally, the system that the drive is being used in should be capable of issuing SMART commands.
Otherwise, provisions have been provided to allow the media wear attributes to be persistent so the
drive can be moved to a SMART capable system to read out the drive wear attribute values.
Product Specification August 2016
28 Intel Confidential 334826-001US
Intel® Solid State Drive DC S3520 Series
Use Case 1 – With a System Capable of SMART Commands
1. On a SMART capable system, issue the SMART EXECUTE OFF-LINE IMMEDIATE (D4h)
sub-command 40h to reset the drive wear attributes.
2. Run the workload to be evaluated for at least 60 minutes. Otherwise the drive wear attrib-
utes will not be available.
3. Read out the drive wear attributes with the SMART READ DATA (D0h) command.
Use Case 2 – With a System Not Capable of SMART Commands
1. On a SMART capable system, issue the SMART EXECUTE OFF-LINE IMMEDIATE (D4h)
sub-command 40h to reset the drive wear attributes.
2. Move the drive to the system where the workload will be measured (and not capable of
SMART commands).
3. Run the workload to be evaluated for at least 60 minutes. Otherwise the drive wear attrib-
utes will not be available.
4. Do a clean system power down by issuing the ATA STANDBY IMMEDIATE command prior
to shutting down the system. This will store all the drive wear SMART attributes to persistent memory within the drive.
5. Move the drive to a SMART capable system.
6. Read out the drive wear attributes with the SMART READ DATA (D0h) command within 59
seconds after power-up.
Example Calculation of Drive Wear
The following is an example of how the drive wear attributes can be used to evaluate the impact of a
given workload. The Host Writes SMART attribute (E1h) can also be used to calculate the amount of
data written by the host during the workload by reading this attribute before and after running the
workload. This example assumes that the steps shown in “Example Use Cases” on page 18 were
followed to obtain the following attribute values:
• Timed Workload Media Wear (E2h) has a raw value of 16. Therefore, the percentage wear =
16/1024 = 0.016%.
• Timed Workload Host Read/Write Ratio (E3h) has a normalized value of 80, indicating that
80% of operations were reads.
• Workload Timer (E4h) has a raw value of 500. Therefore the workload ran for 500 minutes.
• Host Writes Count (E1h) had a raw value of 100,000 prior to running the workload and a
value of 130,000 at the end of the workload. Therefore, the number of sectors written by
the host during the workload was 30,000 * 65,535 = 1,966,050,000 sectors or
1,966,050,000 * 512/1,000,000,000 = 1,007 GB.
The following conclusions can be made for this example case:
The workload took 500 minutes to complete with 80% reads and 20% writes. A total of 1,007 GB of
data was written to the device, which increased the media wear in the drive by 0.016%. At this point
in time, this workload is causing a wear rate of 0.016% for every 500 minutes, or 0.00192%/hour.

5.4.3 SMART Logs
The Intel SSD DC S3520 Series implements the following Log Addresses: 00h, 02h, 03h, 06h, and 07h.
The DC S3520 Series implements host vendor specific logs (addresses 80h-9Fh) as read and write
scratchpads, where the default value is zero (0). Intel SSD DC S3520 does not write any specific values to
these logs unless directed by the host through the appropriate commands.
The DC S3520 Series also implements a device vendor specific log at address A9h as a read-only log
area with a default value of zero (0). Besides that, the DC S3520 Series also implements log address B8h
(if the drive is in disable logical mode, log address B8h will have a failure code). Finally, the DC S3520
Series also implements log at addresses B9h and BAh (both of them are Intel error logs, and read only
for customers).
5.5 Device Statistics
In addition to the SMART attribute structure, statistics pertaining to the operation and health of the Intel
SSD DC S3520 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.
