Seagate just announced their first line of SSDs, named Pulsar. It's a 2.5-inch drive in slightly odd 50GB, 100GB and 200GB sizes, and it's packing some pretty impressive speed.
The Pulsar drives are all 3Gb/s SATA compatible, offering top read/write speeds of 240MB/s and 220MB/s, respectively. For comparison, the current market champ, Intel's X25-M, hits 250MB/s read but only 100MB/s write, and the X25-M tops out at 160GB capacity. These new Seagate drives have a lifespan of about five years, which is about average for current-gen SSDs. The Pulsars began shipping to OEMs in September, so we should start seeing them pretty soon—right now, we don't have individual prices for them, although if Intel's X25-M's prices are any indication, they won't be cheap.
