We had heard talk about Samsung’s 256GB solid state drive back in May and it appears that today the talk has finally come true. Samsung has announced they are now officially manufacturing the large Flash-based drive, and we can tell you it’s fast. What we can’t tell you yet is how much it costs.

The speed of the 256GB drive is double that of Samsung’s 64GB and 128GB drives in what Samsung is calling “…disruptive performance”, with sequential read rates of 220MB/s and write rates of 200 MB/s. Applications can launch as much as 10 times faster than a 7200rpm notebook HDD with speeds that would be similar to a 15,000rpm drive.

Solid State Drives may well be the future of data storage in the computer industry, but with the high price of flash memory at this time SSDs are not seeing much adaption in the consumer market. So poor is the uptake by consumers for SSDs that Seagate will not even target the consumer market with its SSD line launching in 2009.

Somehow OCZ has got around the cost issue normally associated with SSDs with its latest offering called the Core Series SATA II Solid State Drive. OCZ says that the Core series are the first truly affordable SSDs and that the retail price of 50% less than competing products on the market.

Samsung has announced the world’s fastest MLC-based 256GB SATA solid state drive which boasts some amazingly fast read speeds of 200 mps and 160 mps write speeds. It’s also the thinnest and largest capacity drive with a SATA II interface. Salivating yet?

It measures just 9.5mm thick. No pricing info is available yet, but expect it to be expensive. Should you be able to afford one, they’ll be available this September, with a 1.8-inch version coming in Q4.
