Obviously that's okay if the C400's price reflects its inferior performance -- there's nothing wrong with delivering an entry-level product. Fortunately, Micron seems to be taking that route, as the 128GB, 256GB and 512GB versions will sell later this month for $250, $500 and $1,000. That's on par with the existing C300 drives which are available for $255 (128GB) and $485 (256GB), as well as Intel's mainstream 320 Series SSDs.
As it stands, folks shopping for a high-end SSD should probably have their sights set on OCZ's Vertex 3 line, which has topped performance charts around the Web. The Vertex 3 is gradually appearing online in 120GB and 240GB flavors for $300 and $530, but it doesn't seem to be in stock anywhere at the moment. Meanwhile, Intel's performance 510 Series SSDs are available for $285 (120GB) and $615 (250GB) through Newegg.
