Before purchasing the PNY 240GB SSD drive I researched and compared similar items from other brand names before making my selection. Overall the major brand names offer similar specifications regarding the data transfer rate. I found it more useful to compare the individual read and write speeds which can vary between brands and even between similar products made by a single brand. PNY consistently rates amongst the highest read and write speeds which is a true measure of how well the SSD will meet your particular needs.
