ADATA XPG SX930 and Premier SP550 240GB SATA 6G SSD Review @HiTech Legion
 

"Both the ADATA SP550 and XPG SX930 drives come in the typical 2.5" hard drive form factor and both of them are also only 7mm thick. The 7mm thickness allows the drive to be compatible with more products as they get smaller and smaller. One of the biggest differences between the SP550 and the XPG SX930 drives though is that the SP550 uses TLC memory and the SX930 uses an MLC setup."
