What is an IO Accelerator? The IO Accelerator is an advanced storage device that uses solid state storage technology directly on the
PCIe bus, assuring high read and write data rates and accelerated application performance. The associated
application performance improvements will have a positive impact on business results and the ability to
make decisions quickly, resulting in significant cost and time savings.

Latency
HP IO Accelerator offers very low latency access to data (as low as 50 microseconds to read a 4K block), in
other words a virtually zero seek time compared to rotating magnetic media.
