What I'd like to see is something I can get off the shelf at my local Computer Mart (or on the web) that plugs into my PC and gives me raw flash.

If a PCIe expansion socket is sufficient, several companies are now selling that. I remember IBM demonstrating last year a prototype storage server composed of a bunch of Linux systems with Fusion-IO PCI Express cards for storage. It broke some kind of record.

In that system, the flash storage still appeared as a block device, but it did it at the Linux block device interface instead of at the SCSI physical interface.

Fusion io is not raw flash since the driver contains a sophisticated FTL that cannot be disabled. In theory they could release an MTD driver, but they're not going to.

Is the driver you're talking about a Linux kernel module? An object code only one?

What is MTD?

All this has happened before...

Yep.

How you access raw flash. See also UBIFS Raw flash vs. FTL devices.
