1.0 General Description
1.1
Overview
The SanDisk CloudSpeed Eco™ and Ultra™ Gen. II solid state drive (SSD) are designed specifically to address the growing need for
SSDs that are optimized for read intensive and mixed workload applications in enterprise server and cloud computing environments.
Leveraging SanDisk’s proprietary Guardian Technology™ platform, tier-one OEM-enterprise firmware, proven power fail technology,
and the latest generation of enterprise Multi-Level Cell (eMLC) NAND flash, the CloudSpeed Gen. II SSD offers all the features
expected from an enterprise-class drive at the right value.
Available in capacities of 480 GBytes, 960 GBytes, and 1,920 GBytes, the CloudSpeed Eco Gen. II SSD features a 6 Gigabits (Gbits)/sec
Serial Advanced Technology Attachment (SATA) interface and provides up to 525/460 megabytes (MBytes)/sec sequential read/write
and up to 75,000/13,000 Input/Output Operations Per Second (IOPS) random read/write performance.
Available in capacities of 400 GBytes, 800 GBytes, and 1,600 GBytes, the CloudSpeed Ultra Gen. II SSD features a 6 Gigabits (Gbits)/sec
Serial Advanced Technology Attachment (SATA) interface and provides up to 525/460 megabytes (MBytes)/sec sequential read/write
and up to 75,000/30,000 Input/Output Operations Per Second (IOPS) random read/write performance.
The CloudSpeed Gen. II is powered by SanDisk’s proprietary Guardian Technology platform, a comprehensive suite of innovative
features comprised of FlashGuard™, DataGuard™, and EverGuard™ technologies.
FlashGuard extends the native endurance of Multi-Level Cell (MLC) flash-based products. It combines Aggregated Flash
Management, which treats all flash elements as a single system, and Advanced Signal Processing, which dynamically adjusts flash
parameters throughout the life of the SSD. Using these features, with proprietary-enhanced error-correction techniques, FlashGuard
technology provides the endurance enhancements required to enable the use of MLC flash in mission-critical enterprise applications.
CloudSpeed Gen. II implements data path protection using a comprehensive set of features, including:
•
ECC and parity protection on internal data path memories
•
CRC protection on internal SATA link data paths
•
ECC on data resident in flash
•
Flexible Redundant Array of Independent Memory Elements (FRAME) and block-level flash data recovery/redundancy
EverGuard protects against loss of user data in the event of unexpected power interruptions using a third-generation backup power
circuit design and high-reliability discrete capacitors.
SanDisk has built its reputation by providing proven technology and quality products to the most demanding Fortune 100 OEMs.
SanDisk engineers its products to perform at the highest degree of reliability and compatibility.

2.0 Product Description
The CloudSpeed Gen. II includes a NAND flash controller that provides a 6 Gbits/sec SATA interface to the host. Parallel access to
multiple flash sites allows overlapped, multi-block access to rapidly complete data transfer requests. The controller continuously
monitors drive temperature by polling an on-board thermal sensor, enabling notification to the host via a SMART trip in the event of
an over-temperature condition. The backup power circuitry feature provides a holdup capacitor array to ensure data integrity during
power fail scenarios.
2.1
Functional Block Diagram
Figure 1: CloudSpeed Gen. II Block Diagram
2.2
Flash Management
The CloudSpeed Gen. II supports the following techniques for enhanced flash management:
•
Static Wear Leveling: This feature eliminates overstressing flash media by spreading the data writes across all flash physical
address space, including logical areas that are not written by the user.
•
ECC: The CloudSpeed Gen. II utilizes advanced two-level BCH code and a FRAME data recovery algorithm. The drive activates
this second tier of error correction if the ECC engine is unable to correct the data located in failed NAND pages.
•
Bad-block Management: This feature tracks all manufacturing and run-time bad blocks of flash media and replaces them with
new ones from the spare pool.
•
Data Retention Management: As flash is used over the life of the drive, data retention capability declines. The CloudSpeed
Gen. II incorporates multiple data-retention management techniques to ensure the highest data reliability and integrity, even
toward the end of drive life.
•
Minimal Write Amplification: Write amplification is defined as the ratio of total data written to the flash compared to the total
data written by the host. This ratio varies continually as a function of workload. CloudSpeed Gen. II controllers utilize write
optimization, effective wear leveling, intelligent bad-block management, and efficient recycling to deliver an unprecedented,
low write amplification factor. This translates directly to higher and more stable performance over a longer life.

Drive Capacity
2.3
Endurance
The CloudSpeed Gen. II provides the innovative FlashGuard technology feature to extract higher endurance from MLC flash.
FlashGuard incorporates two important technology breakthroughs in the area of flash and SSD system management:
•
Aggregated Flash Management
•
Advanced Signal Processing
2.3.1
Aggregated Flash Management
SanDisk’s Aggregated Flash Management technology prolongs the life of SSDs by treating all flash elements in the SSD as a system
instead of as a collection of discrete elements. Aggregating the management of the flash over multiple pages within a block and over
multiple blocks within the SSD reduces the limitations imposed at the page and block levels, thus extending the life of the drive.
FlashGuard treats each flash cell individually, thereby maximizing the effects of stronger flash elements (i.e., those that exhibit higher
performance capability) while minimizing the effects of weaker elements. The capability of FlashGuard to distinguish between and
take advantage of flash elements at the cellular level extends the endurance of the drive.
2.3.2
Advanced Signal Processing
The controller’s Advanced Signal Processing technology periodically monitors the flash and collects detailed performance statistics.
This information is used to dynamically adjust the flash operating parameters for maximum endurance from the drive throughout its
operational life. To further extend the life of the drive, FlashGuard incorporates a proprietary enhanced error correction technology
that corrects more data errors than is possible with standard schemes.
2.4
Temperature Throttling
The CloudSpeed Gen. II supports temperature throttling to guarantee the life of the drive. With this feature, the drive throttles the
drive performance based on a pre-configured temperature level of 65 °C, which is measured by the drive thermal sensor. When the
critical temperature (65 °C) is reached, the drive throttles write performance and increments the Lifetime Thermal Throttle Activations
SMART attribute (ID 244) counter. Performance remains throttled until the temperature falls to 63°C or below.
2.5
Mean Time Between Failures (MTBF)
The MTBF statistic for the CloudSpeed Gen. II is calculated based on the MIL-HDBK-217 standard MTBF Values.
Table 4: MTBF Hours
MTBF (Hours)
All >2,000,000
NOTE:
The throttling level varies depending on the current workload.

Remote LED
In compliance with the SATA standard, pin P11 on the SATA 15-pin power connector supports a remote LED. Because the signal is not
suitable for directly driving an LED, a circuit external to the device must first buffer the signal. When connected, the remote LED
indicates activity. Refer to the SATA standard for more details.
4.3
Thermal Sensor
The CloudSpeed Gen. II contains a thermal sensor on the printed circuit board. The drive polls the sensor for temperature information
every 60 seconds, and the drive stores the highest and lowest readings in the drive logs. This temperature represents the temperature
of the NAND, not the drive case.

Power
4.4.1
DC Noise and Ripple
Noise is a random fluctuation in an electrical signal. Ripple is the small unwanted residual periodic variation of the direct current (DC)
output of a power supply that has been derived from an alternating current (AC) source. This ripple is due to the incomplete
suppression of the alternating waveform within the power supply.

Supported SMART Operations
Self-Monitoring Analysis and Reporting Technology (SMART) attributes provide diagnostic information regarding drive operation.
SMART alerts the host to potential drive problems, allowing system operators to assess the situation and back up data prior to an
operational failure.
With SMART, the CloudSpeed Gen. II continually monitors a number of key internal operating parameters to identify performance
changes that could be a sign of impending drive failure. When the drive detects such a condition, the drive alerts the host system of a
reduction in reliability or performance.
