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.

Hard drives days are numbered.

A recent article shows that Hard Drives are 50 years old. I'd say sometime in the next 10 years, they will be replaced by a new technology. Solid-State Flash Drives are a possibility.

Flash seems to follow moores law.... every 18 months, capacity doubles.
3 years - 122 GB
6 years - 488 GB (probably big enough)
9 years - 2 TB

Flash seems to have grown in speed and capacity faster than HD technology over the last 5 years. I think it will eventually take over.

HDDs will still be used for tens of years I think. Now that we are just starting to use the first generation of perpendicularly recording drives, we are not even close to the maximum density hdds will have in the next years. We should see 1TB single drive within a month for <500$. It will take a lot of years before you can see a similar product that uses flash.

doubt that'll ever happen.
these flash based drives are designed for performance, NOT for storage. Your OS can only take up so much space, and flash drives have enough capacity to compensate those demands. But if you're talking data storage, harddrives are gonna be here to stay for a while, until another high capacity storage medium becomes standardized.
