1. Introduction
1.1 General Description
The SanDisk® SSD P4 builds on the momentum of the first and second generations
of pSSD and the overall trend in the market towards smaller, thinner computing
machines that enable mobility and connectivity on the go.
Using NAND flash based storage to replace Hard Disk Drives, SSD P4 provides a
much improved user experience. In addition to being rugged and reliable, the third
generation modular SSD beats HDDs in every possible metric – power consumption,
sequential and random read performances as well as sequential and random write
performances. The SATA interface aligns with the global transition in the industry,
which is enforced by the platform’s chipsets.
Using the advanced 32nm memory geometry is provided in capacity range of 32GB-
128GB. The small form factor of SSD P4 enables further miniaturization of
Netbooks, SmartBooks and Tablets designs and opens doors for a whole range of
other applications.
The SSD P4 product complies with the ATA-8 standard and is electrically compatible
with a parallel IDE/ATA disk drive.
In addition to the mass storage-specific NAND flash memory chips, the SSD includes
an on-board intelligent controller for managing interface protocols, data storage and
retrieval, error-correcting code (ECC), defect handling and diagnostics, advance
power management and clock control. Using innovative data management
algorithms, the SSD P4 provides superior sequential and random IO performance,
and ensures data reliability.

Unlike an HDD, the SSD P4 has no moving parts. It keeps working in environments
such as classrooms, kiosks and in space-restricted server racks. The patented flash
management technology brings top data integrity to the SSD, even during power
losses. Dynamic bad block management, dynamic and static wear-leveling, and
robust error detection and correction code (EDC/ECC) ensure data integrity.

1.3 Functional Description
SSD P4 contains a high level, intelligent subsystem. This intelligent (microprocessor)
subsystem provides many capabilities not found in other types of memory cards.
These capabilities include the following:
•Standard ATA register and command set
•Support for Trim command
•S.M.A.R.T. feature supported
•Host independence from details of erasing and programming flash memory
•Sophisticated system for managing defects (similar to systems found in
magnetic disk drives)
•Sophisticated system for error recovery including a powerful error correction
code (ECC)
•Advanced power management for low power operation
•Implementation of dynamic and static wear-leveling to extend card’s life
1.4 Defect and Error Management
SSD P4 contains a sophisticated defect and error management system that is similar
to the systems found in magnetic disk drives, and in many cases, offers
enhancements. If necessary, the SSD card will rewrite data from a defective sector
to a good sector. This action is completely transparent to the host and does not
consume any user data space.
The SSD soft error rate specification is much better than the magnetic disk drive
specification. In the extremely rare case that a read error does occur, the SSD P4
products have innovative algorithms to recover the data by using error detection
code and error correction code (EDC/ECC). These defect and error management
systems, coupled with the solid state construction, give SSD P4 unparalleled
reliability.
1.5 Wear Leveling
Wear leveling is an intrinsic part of the erase pooling functionality of SSDs using
NAND memory. Advanced features of dynamic and static wear-leveling, and
automatic block management are used to ensure an even distribution of write erase
cycle throughout the entire device, regardless of how dynamic or static the data
written is. This guarantees high data reliability and maximizes flash life expectancy.
1.6 Bad Block Management
Bad blocks are occasionally created during the life cycle of a flash component, in a
phenomenon called dynamic bad-block accumulation. These bad blocks must be
marked and replaced dynamically in order to prevent read/write failures. When a bad
block is detected, the embedded Bad Block Mapping algorithm maps out the block,
which will be not used for storage anymore.

1.7 Non-Volatile Write Cache
The third generation of modular SSD, the SSD P4 supports a unique feature to
improve random write performance and ensure very positive user experience.
Studies show that modern operating systems mostly access the storage device using
small access blocks, with the majority being a 4KB access blocks.
The small logical access blocks conflict with the physical block structure (>1MB) for
the newer generation flash memory technology. Therefore, to bridge this difference,
SSD P4 employs a non-volatile SLC Flash write cache, nCacheTM
The cache size of the SSD P4 is over 500MB
. The nCache™ is
used to accumulate these small writes (called segments) at high speed and then
flush & consolidate them to larger MLC section of the NAND Flash memory array in
the background during idle time.
4
Also nCache™ is a non-volatile cache and hence there is no exposure to data loss
- an order of magnitude larger than
other competing solutions that use DRAM based cache. Due to its large size, for most
part of daily user activity nCache™ never overflows and the end users experience
high SLC burst performance rather than the sustained performance. Once the
nCache™ becomes full, the performance of SSD P4 drops to the steady state
condition.
5
1.8 Power Management
.
Although power consumption is not actively managed by a PATA host, the SSD P4
supports an advanced power management system. This system is internally
managed (i.e., requiring no special interaction with the host) in order to agressively
manage and preserve power consumption.
Upon completion of a command, the P4 will start an internal timer and, after 20ms
without receiving another command, will automatically enter an intermediate low-
power mode (i.e., Idle time power mode). In order to further enhance the P4’s
performance, the flash management can utilize this idle time for performing internal
house-keeping operations. Doing those activities, i.e. – freeing up space in the
nCache, while the card is idle will not increase overall power consumption, since
these operations will have to be executed eventually. Executing them during idle
time will prevent stalling the host while they are taking place and will enable a better
utilization of the Data Cache, as it will have additional free space when the host will
access the device. At the moment a new command is received from the host the
internal operations will be terminated and the host command will be serviced with
minimal delay. If no command is received after 30 seconds, execution of the house-
keeping activities will terminate and the lowest-power mode will be entered.
4The cache size scales with capacity. For 32GB product the cache size is over 500MB.
5In order to prevent any data loss during removal of the power supply, the time it takes the input voltage
to drop from the nominal voltage down to 2V must be at least 5ms.

6. Reliability Characteristics
6.1 Error Rate
Non-recoverable error rate is 1 error per 1014
6.2 MTTF (Mean-Time-To-Failure)
bits read.
The reliability figure of merit most often used for electronic equipment is Mean-Time-
To-Failure (MTTF). SanDisk estimates MTTF using a prediction methodology based in
accordance with the Telcordia Special Report SR-332. The prediction is based on a
Parts Stress Analysis.
Quality levels were defined as industrial grade (I) for all of the components. The
detailed prediction for the system was performed at a temperature of 25°C in a GB
environment.
The following table summarizes the estimated MTTF results for each capacity.
Capacity Condition MTTF (Hours) Estimated FITs
