TDK's solid state hard drive
Mainstream solid state drives not far away

TDK announced this week that it has developed the smallest in its class solid state NAND flash memory drive. The drive is roughly the size of a typical notebook hard drive but does not rely on mechanical rotating platters and read/write heads for operation. Instead, the tiny drive uses high-speed NAND flash memory and can store up to 32GB of data using sixteen 16 gigabit chips.

According to TDK, the drive is 20% smaller than 2.5.-inch notebook drives. It also consumes less power and isn't prone to the same failure factors as traditional drives.  TDK's Japanese press release claims:

Along with TDK's "GBDriver RA5" NAND flash memory control LSI, this semiconductor disc features four super capacitors (optional) for the power supply interruption assist circuit and a 2.5-inch ATA interface. The GBDriver RA5 supports "UltraDMA mode2" data transmission mode that boasts a maximum data rate of 33.3 MB per second.

TDK isn't the only company looking to flash technology. DailyTech previously reported that Toshiba was also on the road to releasing its own line of solid state disk drives. The technology overall has progressed significantly over the past several years, with prices falling from the thousands of dollars for a 1GB solid state drive to much more consumer affordable prices. Samsung is also hard at work on solid state drives as well. No release dates have been set however.

Samsung's one is faster

This is is limited to UDMA2 while Samsung does UDMA4. Some others already do UDMA5 and have even higher transfer rates, but I guess for laptop/ipod usage this TDK one is good enough.

And this is only a start you can expect multi channel memory to grow to speeds able to saturate SATAII with ease soon if it or a competing format becomes popular. Hopfully people will start intigrating a higher speed lower latency interface for these as they develope.
