Just red wine induced thinking here but has anyone tried running Win(7 or XP) off a bootable pendrive instead of an internal hard drive?
Was it better or worse performance?

I've booted various OS's from USB - it is much, much worse performance. The flash memory in a USB stick is pretty low quality compared to an SSD. Add in the bus itself and its overheads, and transfer speeds are much lower than you'd want. Lower than a standard hard drive in my experience.Quote:

You can boot off a USB drive for a quickish boot/op on certain OSs, VMWare ESXi is designed to allow boot from a USB key and you can put many linux distros on one. It is also a feature of Windows 8 but prior versions of Windows were restricted from booting off a portable device.
Ok - Plan B :)
What about an SD Card (in netbook/laptop slot thingy)?
Can you boot 7/XP off that?

The only way you will get decent performance out of a USB flash drive is if you buy one of the expensive flash drive-sized USB 3.0 SSDs. e.g. SuperTalent RC8 (£87 for 25GB) or Kingston DataTraveler HyperX 3.0 (£98 for 64GB).
Should be perfect for a Windows To Go drive. :)
Most SD card readers I've ever seen are USB devices, even the built in ones - they're just hard-wired to the USB bus directly.Quote:

But as I say, you may well find that the reader is hampering the transfer speeds in between.
Theoretically, if you could find a bus which could handle it, SD can run at over 800Mb/s, which is ridiculously fast, but I don't think anyone makes cards that fast at the moment.
Note that even with those, you'll want USB3 rather than USB2 to get decent speeds out of them.Quote:

One of the best things about Windows 8 (and consequently Windows to Go) is that it will include USB 3.0 drivers out of the box. Unlike Windows 7, you won't have to mess around integrating them using DISM.Quote:

PS I'm talking USB 2 - it was an idea to try out on old laptops :)
Windows 98 Live CD? ;)Quote:

I actually have an ISO image of xp where you can install it on to a usb stick. You have to edit the cab files so it doesn't flush the USB channels during the installations. I found the instructions a few years ago on how to do it. The speed is poor and it locks it to that hardware type meaning it isn't hardware independent. Also as its a usb with limited read write cycles you could only run it for a month solos before it dies. If any ones interested I can dig up the instructions and/or ISO image.
Take a look at readyboost ReadyBoost - Windows 7 features - Microsoft Windows
