Those who live for nothing more than to cram their SSD to the brim with useless data, only to mass delete the bulk of it, rinse, and repeat, we've found the perfect drive for you. Hitachi ULSI Systems Co., a subsidiary of Hitachi, has reportedly "developed a solid state disk on which data can be overwritten 100 times more than is possible on a conventional product of that type." On the device, "data predicted to have a high overwrite frequency is stored on the DRAM and not sent to the flash memory, while information with low overwrite frequency is stored on the flash." Consequently, "overwrite frequency on the flash portion" is substantially less than that of traditional alternatives. According to the company, it will start shipping out samples next month, but there's no mention of a commercial launch date. [Warning: Read link requires subscription]
