'[EE] Does any vendor sell a USB SS hard drive base'
I want to load a USB solid state hard drive externally ( not using the
USB ) from a digital video source at up to 23Mbytes /sec and then
read the data into a computer using the USB port.
load the streaming 8 bit data into dual port memory and read it back
out using GPIO on the computer. A DMA controller would be cool if it
accepted streaming data , loaded it into memory and then allowed the
computer to access it a byte at a time. Are there any modules or
chips that will do this ? DRAM, SDRAM , ??? is okay as long as it is
fast enough. Power is not an issue.

compact flash with a usb card reader should be fast enough to do this.
I think you'd need to look around 233x or better.

Have you looked at using the FTDI FT2232H?
Better than 25MBytes/Sec - no need for buffer memory at all as long as
the software running on the PC can eat it that fast. Probably will
want to connect to its own host controller on the PC (no hubs, nothing
else on the USB host controller).
If not, build a buffer inbetween the video output and the USB chip.
An FPGA with RAM seems ideal for this. Most FPGA starter kits should
have the needed RAM and USB interface.
