SanDisk uSSD 5000  
Product Manual  
1. Introduction  
1.1 General Description  
The SanDisk uSSD takes the benefits of flash storage to new markets with  
low-capacity storage requirements, most notably the low-cost PC (LCPC).  
Rugged and reliable, it is a fraction of the size and cost of a hard disk drive  
(HDD) in the 1 to 16 GB range. SanDisk adds high performance to the uSSD  
offering, based on an advanced controller that exemplifies the company’s  
years of USB expertise.  
1.1.1 Applications  
The SanDisk uSSD offers a no-compromise flash-based storage solution for:  
LCPCs that need rugged reliability and require up to 4 GB. The uSSD can  
meet these requirements more cost-effectively than an HDD  
Desktops that support Microsoft® Vista and can benefit from enabling  
ReadyBoost® up to 4GB.  
Point of sale (POS) stations, where the uSSD replaces the HDD  
Blade servers, where the uSSD is ideal to store critical backup files and  
provide boot functionality  
1.1.2 Rugged and Reliable  
Unlike the HDD, the SanDisk uSSD has no moving parts. It keeps working in  
challenging environments such as classrooms, kiosks and on space-restricted  
server floors. The patented flash management technology brings top data  
integrity to the uSSD, even during power losses. Dynamic bad block  
management, dynamic and static wear-leveling, and robust error detection  
and correction code (EDC/ECC) ensure data reliability.  
1.1.3 High Performance  
The uSSD achieves a sustained read speed as high as 30 MB/sec and a  
sustained write speed of up to 20 MB/sec with single-level cell (SLC)  
technology.  
1.1.4 Cost Effective  
There is no need to pay for more capacity than you require. The uSSD lets you  
purchase just the right amount of storage, packed inside a memory device  
that’s 25% smaller than a 1.8” HDD. It offers you the choice of single-level  
cell (SLC) flash technology or the more cost-effective multi-level cell (MLC)  
technology.

SanDisk uSSD 5000  
Product Manual  
1.3 Scope  
This document describes the key features and specifications of the uSSD 5000,  
as well as the information required to interface this product to a host system.  
1.3.1 Technology Independence  
To write or read a sector (or multiple sectors), the host computer software  
simply issues a Read or Write command to the module.  
This command contains the address and the number of sectors to write/read.  
The host software then waits for the command to be completed.  
The host software does not participate in the details of how the flash memory  
is erased, programmed or read. This is extremely important as flash devices  
are expected to increase in complexity in the future. Because the uSSD 5000  
uses an intelligent on-board controller, the host system software will not need  
to be changed as new flash memory evolves. As such, systems that support  
uSSD 5000 now will be able to access future SanDisk Modules built with new  
flash technology without any need to update or change the host software.  
1.3.2 Defect and Error Management  
The uSSD 5000 contains a sophisticated defect and error management  
system.  
If necessary, the Module will rewrite data from a defective sector to a good  
sector. This is completely transparent to the host and does not consume any  
user data space.  
The uSSD 5000 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 uSSD 5000 has  
innovative algorithms to recover the data by using hardware on-the-fly Error  
Detection Code/Error Correction Code (EDC/ECC), based on a BCH algorithm.  
These defect and error management systems, coupled with solid state  
construction, give the SanDisk uSSD 5000 unparalleled reliability.  
1.3.3 Wear-leveling  
Wear-leveling is an inherent part of the erase-pooling functionality of the  
SanDisk uSSD 5000, using NAND memory.  
Advanced features of dynamic and static wear-leveling and automatic block  
management are used to ensure high data reliability and maximize flash life  
expectancy.  
1.3.4 Bad Block Management  
Bad blocks are occasionally created during the lifecycle of a flash component,  
in a phenomenon called dynamic bad block accumulation. These bad blocks  
must be dynamically marked and replaced to prevent read/write failures.  
When a bad block is detected, the embedded bad block mapping algorithm  
maps out the block, which is then no longer used for storage.

2.6.1 MTTF  
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 on reliability data for the individual components in  
SanDisk products.  
Component data comes from several sources: device life tests, failure analysis  
of earlier equipment, device physics, and field returns.  
SanDisk uses following methods to predict reliability:  
Telcordia Special Report SR-332, Reliability Prediction Procedure for  
Electronic Equipment (RPP).  
British Telecom Industry HRD5, Handbook of Reliability Data for Electronic  
Components used in Telecommunication System.  
Table 6 summarizes the MTTF prediction results for various uSSD  
configurations. The analysis was performed using a RAM Commander™ failure  
rate prediction.  
Failure Rate: The total number of failures within an item population,  
divided by the total number of life units expended by that population,  
during a particular measurement interval under stated condition.  
Mean Time To Failures (MTTF): A basic measure of reliability for  
repairable items: The mean number of life units during which all parts of  
the item perform within their specified limits, during a particular  
measurement interval under stated conditions.
