DRAM Buffer
SSDs designed with a DDRIII SDRAM buffer which is support high transfer rate as a data buffer for the SSD; SSD with
SDRAM buffer is able to deliver excellent random data transfer speed.

Power Interrupt Data Protection Technology
In the event of an unstable power supply, SSD loses power before it can finish programming process from host to flash,
this may cause data being written to the incorrect block and further leads to data corruption.
Power Interrupt Data Protection Technology is applied with several tantalum capacitors to provide power buffering after
host power interruption. The Data Protection Technology provides enough time for the SSD controller can write all DRAM
buffer data to flash, all data will be protected and without data loss.
The ability of Power Interrupt Data Protection Technology is able to write 1.28MB of data within 60ms.
This ensures all data in the DRAM buffer can be successfully written into flash.
Traditionally, super capacitors were applied in most SSD products, the advantages of tantalum capacitors over super
capacitors are:
Tantalum capacitors are electrolyte free.
It is able to maintain its designed capacitance for several years when used within design limits.
Wide operating temperature range.
Tantalum capacitors can operate from temperature range of -55C to +125C, which is very suitable for industrial and
military usage.
Tantalum capacitors have an ultimate high volumetric efficiency (CV/cc).
For example, a 50-microfarad tantalum capacitor can be equal and to properly replace a 500-microfarad aluminum
capacitor.
