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.

too slow, even the interface has a burst of 33.3MBps

Agreed. The supercapacitors are a nice touch. Aside from that, this is nothing compared to Samsung's 64GB CF card. If Samsung can cram 64GB into a single CF card, they should easily put a few hundred GB into a 2.5" form factor, running at maximum PATA or SATA speed.

A. Samsung is still working on that technology
B. Speed might not be the same (memory cards aren't hard drives)
C. Cost is easily going to be much higher per GB when in card form

Sandisk already has 40MB/sec CF cards out (their Extreme IV product line) up to 8GB per card. Any new SSD product being introduced at slower than 40MB/sec just isn't even worth bothering.

As for cost being higher in card form - somewhat tangential. The point is there's no excuse for it to cost so much in drive form, and if you can already cram 8GB into the space of a CF card (36.4mm x 42.8mm x 3.3mm = 5141.136mm^3) then you can surely cram a whole lot more into the space of a 2.5" HDD (9.5x69.85x100.2mm = 66490.215mm^3).
