That's right, ZOTAC offers a number of SSDs, including a PCIe based one, but today Hardware Canucks examines the Premium Edition 480GB.  It uses the Phison PS3110 controller, 256MB NANYA DDR3 for cache and the slightly older 19nm Toshiba Toggle MLC NAND.  This is similar to other lower cost SSDs and so you would expect the performance to be similar as well.  This is indeed the case, performance is similar to the PNY XLR8 and the Crucial MX200 drives and the price is attractive, Hardware Canucks saw it on sale for $65US for the 240GB model and less than $140 for the 480GB.  If you are looking for a lower cost SSD you should check out the full review.

"The mid-tier SSD market is a crowded place these days but Zotac may have a standout contender with their affordable yet fast Premium Edition."
