Solid-state drives based on those newfangled SandForce controllers are multiplying. Following Corsair and OCZ, Mushkin has now introduced a trio of Callisto SSDs sporting the SandForce SF-1200 controller—and blistering transfer speeds, at least according to the company's numbers.
The Callisto lineup includes 60GB, 120GB, and 240GB models, all rated for top speeds of 285MB/s when reading and 275MB/s when writing. In SSD tradition, Callisto drives have 2.5" form factors and 300MB/s Serial ATA interfaces, as well. Mushkin says these puppies have a two-million-hour mean time between failures, and it covers them with a three-year warranty.
That level of performance doesn't come cheap. Callisto SSDs are "available immediately" from Mushkin's online store at $218.49 for the 60GB drive, $369.99 for its 120GB sibling, and $666.49 for the 240GB flavor. Those are special "web" prices, by the way; Mushkin actually quotes regular list prices of $240.49, $406.99, and $733.49 for the three drives, respectively.
Price tags like those seem par for the course when it comes to SandForce-based offerings. OCZ's 50GB Vertex 2, for instance, sells for $199 at Newegg. By contrast, you can still grab an 80GB Intel X25-M for just shy of $220. The Intel drive has a top write speed rating of only 70MB/s, however.
