Solid-State Drive (SSD) for Industrial Use
SDG8B Series

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

• Equipped with high-speed, highly durable SLC (Single Level
Cell) NAND flash memory

• 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, respectively

• Error-correcting ability: 8 or 15 bits/sec ECC (automatically
selected by the flash memory's judgment)

• 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.
(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.)

• Perfectly prevents collateral errors; due to TDK's proprietary
flash memory control system SSD is designed to have higher
durability for system power-off.

• 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.

• Supports security functions based on ATA standards. Customers
can set or cancel passwords to prevent falsification of leaking of
personal and confidential information.

• Dedicated FAE (Field Application Engineer) system provides
speedy and reliable solutions e.g. system compatibility
verification and customizing.

• 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.

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.

• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercur y, hexavalent chromium, and specific
bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.
