I heard that NAND flash memory costs $X per GB, so why isn a 32GB SSD under $1000?
*Updated 12/29/07* You get what you pay for. That’s why Transcend is cheap, while MTRON and Memoright are more expensive (but worth it). After we first wrote the answer to this question, MTRON released their Mobi series which IS under $1000 for 32GB. Way under. $725 as of this writing. ORIGINAL ANSWER: Simply conjecturing that NAND flash chips costs X dollars per GB, and doing simple math is irresponsible reporting by the media. First of all, there are more parts than just the flash chips. There is the controller and engineering required for you to be able to plug it into ANY computer and have that computer recognize it has a hard disk. Secondly, there are different grades of NAND flash. The best manufactures, such as PQI, M-Systems, Bitmicro, and Adtron use Industiral Grade Flash. (PQI uses Samsung NANDs). The companies that charge half the price of PQI SSDs use consumer grade flash. It is inferior and unstable. Super Talent, Q-Memory, and others produce SSDs that are so unstable that
