Driving fast on the cost curve. Flash prices need to drop about 50% a year to keep volumes growing. Putting more flash on a wafer helps do that. The new process produces 1.6 TB of NAND flash on a 300 mm (12 inch) wafer.

The key? The 34 nanometer chip feature size - even smaller than Intel's latest CPUs - enables the smallest 32 G/bit flash chip ever.

How small? As Intel/Micron note in their joint press release:

The 34nm 32Gb chip was designed with solid-state drives in mind. The product will enable more cost-effective SSDs, instantly doubling the current storage volume of these devices and driving capacities to beyond 256 GBs in today's standard, smaller 1.8-inch form factor.

Will this make flash drives affordable? Nope - but it is a step in the right direction.

Current 32 Gbit MLC NAND costs about $2.60-$2.75 per gigabyte. That means a 256 GB flash drive would cost almost $700 just for the chips. Add in packaging, support chips, corporate overhead and that is well over $1,000 for the drive alone.

By the time the new chip ships in volume late this year the price will be lower. But consider that a 160 GB 2.5" drive costs $60 online. That is cost-effective storage.

The Storage Bits take Regular readers know that I have my doubts about how popular notebook flash drives will be in the coming years. They cost a lot for what you get.

But it is good to see the technology making progress. We all benefit from that.

Yet as small as 34 nm is, disk drive magnetic bit sizes are even smaller. And well on their way to even smaller feature sizes.

Comments welcome, of course. I've been testing a 16 GB Corsair Voyager thumb drive. More on that soon.

  • Concerns with flash

    My main concerns with flash isn't necessary space; 64gb max is all I really need since I store all my stuff on an external hard disk. The problem I have, however, is the reliability factor (the limited number of writes) and the cost.

    I'm sorry, but $1000+ for a flash drive? no way, I'd sooner have 15minutes less battery life than to be royally rogered by the chip companies who think that they're 'born to replace the hard disk'. Maybe once the chip companies lose that chip off their shoulder, and realise how much Joe Average makes per year, then maybe they can also realise that the prices they charge are unrealistic.
