TDK Computer Drive SDG8B Series User Manual

(1/3)  
U.DMA6-compatible Parallel ATA (PATA)  
Solid-State Drive (SSD) for Industrial Use  
SDG8B Series  
Conformity to RoHS Directive  
Equipped with SLC flash memory and  
highly reliable 2.5-inch IDE solid-state drive with TDK GBDriver RA8  
1GB, 4GB, 8GB, and 16GB  
TDK industrial SSD(Solid State Drive): the SDG8B Series are high-speed and highly reliable flash memory disk equipped with TDK’s own  
NAND-type flash memory controller IC, GBDriver RA8. The series features high-speed data access with effective reading and writing  
speeds of 45 MB/sec and 28 MB/sec, respectively, and has a powerful error-correcting ability that can be extended up to 15 bit/sector  
ECC, thereby achieving high data reliability. In addition, the SDG8B Series has TDK's proprietary algorithm that minimizes bit error (read  
disturb error) resulting from repetition of data reading, as well as the risk of data corruption (collateral data error) due to power-off during  
data writing; both features help provide perfect reliability.  
Furthermore, the newly developed static wear leveling algorithm levels the erasing times of the flash memory in all areas of the memory;  
this function has considerably improved the rewriting life of the flash memory. The product also enables erasing times of all memory  
blocks to be obtained as SMART (Self-Monitoring & Analysis Reporting Technology) information, thus allowing flash life-span to be  
evaluated and detected quantitatively. With technical support by dedicated FAE, these SSD are ideal for industrial use and embedment.  
FEATURES  
• Equipped with TDK's proprietarily developed NAND controller IC  
GBDriver RA8  
• Supports security functions based on ATA standards. Customers  
can set or cancel passwords to prevent falsification of leaking of  
personal and confidential information.  
• Equipped with high-speed, highly durable SLC (Single Level  
Cell) NAND flash memory1  
• Dedicated FAE (Field Application Engineer) system provides  
speedy and reliable solutions e.g. system compatibility  
verification and customizing.  
• Compatible with PIO mode0-6/Multiword DMA mode0-4/Ultra  
DMA mode0-6 High-speed data access with reading and writing  
speeds of 45 MB/sec and 28 MB/sec, respectively2  
• Error-correcting ability: 8 or 15 bits/sec ECC (automatically  
selected by the flash memory's judgment)  
• Complies with RoHS Directives as a solid-state drive. The  
components, lead terminals, etc. are all free from hazardous  
substances prohibited by the RoHS Directives of the EU  
(European Union). Therefore, the product can be safely used  
overseas.  
• TDK's proprietary static wear leveling algorithm levels the  
erasing times of all the areas (blocks) of the equipped flash  
memory and considerably improves the rewriting life-span of the  
memory.3  
1 A product equipped with MLC (Multi Level Cell) NAND can be provided  
on request.  
2Dependent on flash memory connection configuration and system  
environment.  
(As reference, the SDG8B SSD with a 16GB capacity can be  
rewritten (erased) 6.2 billion times. This is equivalent to 20-times  
rewriting (erasing) per second over a ten year life.)4  
• Perfectly prevents collateral errors; due to TDK's proprietary  
flash memory control system SSD is designed to have higher  
durability for system power-off.  
3 The scope of static wear leveling execution can be customized. (Outside  
the scope of static wear leveling execution, dynamic wear leveling is  
executed).  
4 This applies to a product equipped with an SLC flash memory with a  
structure of 4KB/page.  
• Supports SMART commands; histogram display of erasing  
times of all memory blocks enables memory life-span to be  
managed quantitatively.  
• Equipped with a function to set the number of all sectors which  
allows customization of the number of logical blocks per sector  
allotted to the data area.  
For example, decreasing the number of logical blocks can  
increase the possible erasing times of the flash memory, and for  
those applications that do not need a longer life, increasing the  
number of logical blocks can increase the memory capacity to  
the maximum. CHS parameters can also be customized.  
• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific  
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.  
• All specifications are subject to change without notice.
