Following on the heels on its SSD 520 release, Intel is rumored to be getting ready to unveil a couple more drives in May. Rumor has it that the company will introduce a new 300 Series model (codenamed Maple Crest) for the mainstream consumer market and a 720 Series (codenamed Ramsdale) for enterprise applications.
The rumor lacks some detail, such as what storage size it will be available in, what controller it will use, or what interface it will use. Its predecessor uses SATA 3Gbps and is available in 40GB, 80GB, 120GB, 160GB, 300GB, and 600GB sizes, so I would imagine that would be a safe guess that it will at least meet these, if not exceed.
Beyond the rumored May relase, Intel is set to transition to 20nm NAND flash in Q3 and will most likely release a brand new 500 Series solid-state drive codenamed King Crest. Q4 should bring updates to the 700 Series with larger sizes and higher performance. It'll be interesting how the other SSD manufacturers counter these releases.
