I saw some high performance USB memory sticks today in a computer shop (16GB, 25MB\sec transfer) and wondered if this would be a viable option for Resolume.
they would work maybe to stream one clip from. 25Mb/s isn't very fast, look at the post about the SSD from bart, fast is 150Mb/s SSD standard drive do about 50-80Mb/s.
It can lighten the load of your internal hard drive, by streaming only 2 clips from internal drive and 3rd/4th clip off USB stick you will probably get a higher frame rate as the HD reader head doesn't have to seek back and forth to different clips on drive.
I don't think its really worth it though. My decision is to wait till the intel x25 SSDs get cheaper and a bit bigger. Or the next level SSD controller comes out.
If you have an E-SATA connection on your computer an E-SATA external will get better speeds than the USB key and allow you to offload 2-3 clips off external HD and run resolume and a clip or two of internal drive.
Any other quantumConfigs we can dream of to squeeze last bit of performance out...
