Toshiba announced today that their latest-generation solid state drives, featuring the company’s new 43nm MLC NAND-flash manufacturing technology, have just started shipping. Available in 64, 128, 256 and 512GB capacities, the drives won’t be available directly to the public initially but rather as an OEM product for the notebook, gaming and home entertainment markets.

They’ll come in both 1.8 and 2.5-inch form factors and are capable of up to 230MB/s and 180MB/s sequential read and write speeds, which is pretty impressive. Unfortunately Toshiba was not forthcoming about which companies will be getting the drives or at what price.

Looking at a previous 512GB SSD option available exclusively on Protege laptops and a similar-capacity offering from Super Talent, I gather Toshiba’s new flagship drive will set you back some $1,500.
