Read/Write Performance

Will SSDs Take Over The Enterprise?
By

While the Cheetah 15K.5 can beat the MemoRight flash SSD in maximum throughput both in reads and writes, it cannot maintain the ceiling of almost 130 MB/s once you start filling up the drive. In this case, data is not only read and written on the outer sectors of the rotating platters, which show the highest absolute velocity, but slower inner sectors have to be used. Throughput is reduced as capacity use is increased.

The Cheetah 15K.5 still looks very interesting for sequential write operations, as the MemoRight flash SDDs cannot beat this top-notch conventional hard drive. If you are about to create a high-end system to deal with high bandwidth video streams, some Cheetah 15K.5 drives might be the better option. Of course, they also have a higher capacity of up to 300 GB, as opposed to the 128 GB maximum of the MemoRight flash SSDs.
