The Corsair Nova is built around the venerable Indilinx Barefoot controller, featuring 64MB of cache, and comes in either 64 or 128GB capacities. Speeds are a bit faster on this series, with the larger model reaching up to 270MB/sec read speeds and 190MB/sec write speeds. The 60GB version maintains the same read performance but has slightly slower write speeds as it is rated up to just 110MB/s.
Meanwhile, the Reactor series sees JMicron crawling back into the mainstream SSD market with its new JMF612 controller. Corsair lists a 60GB version capable of 250MB/sec read and 110MB/s write speeds, while a 120GB model bumps write throughput to 170MB/s. Hoping to dispel any concerns and bad memories, the company actually stressed that the JMF612 "incorporates 128MB of DDR2 cache memory for stutter-free performance." It also included a USB 2.0 port for added connectivity besides 3.0Gbps SATA.
As far as pricing is concerned, the Reactor SSDs are priced at around $185 and $349 for the 60GB and 120GB drives, respectively, while the Nova series comes in at around $199 for the 64GB and $375 for 128GB model. All four drives are shipping now and come with a two-year warranty.
