After historically fighting flash storage, Seagate today confirmed its change in direction with the launch of its Pulsar solid-state drive. The 2.5-inch, SATA drive is useful for notebooks but chiefly targeted at servers and other computers where both speed and longevity are important. By using single-level cell flash memory, it has an 0.44 percent annualized failure rate and yet reaches peak read speeds of 240MB per second and peak writes of 200MB per second.
