Samsung Producing 256GB SSDs Rob Bushway11/20/2008 On Wednesday, Samsung announced that they have begun producing 256GB solid-state drives, increasing their capacity from their currently available 64GB and 128GB drives. In addition, performance on the new drive has more than doubled. From CNET:Advertisement The drives combine sequential read rates of 220 megabytes per second, with sequential write rates of 200MBps. "This sharply narrows the performance gap between read and write operations to only 10 percent, compared to a read-write speed difference of between 20 (percent) and 70 percent for other SSDs," the company said. No word on pricing.
