Most PC's built in the last 5 years can boot from a USB memory stick, you can get 8GB for less than $80 if you look around.

Re: [Flexradio] Disk-less Flex Radio
Whoa .. I am lost somewhere! I am not aware of a modern Microsoft OS that boots and runs from anything but a hard drive. I have seen Linux versions that will boot from a CD ROM but that's as close as I have seen it. PowerSDR does not yet run on Linux. Most computers that I am aware of purposely make it impossible to boot from a USB device for security reasons. Let a hacker loose in a corporate environment with a Sans Disk and havoc would wreak if they did that. It's a great idea and I am all for it but just have not seen any way to do it and you are quoting CPU usage figures.

Re: [Flexradio] Disk-less Flex Radio
What are the transfer rates on a USB stick? I have the feeling they will not be very good. However, I did some testing last year using a Samsung 32 GB solid state hard drive and it blew away the SATA and ATA/100 drives on read transfer rates and was slightly better on write transfer rates. However the drive cost over $3000. I recently looked at some 6 GB solid state drives and they ran about $650. The beauty of the little 6 GB drives is that they plug directly into the IDE connector on the motherboard. So to Larry's question, the solid state drives look to the system like a 'normal' IDE drive. The solid state drives (at least the Samsung) are also rated for about 2,000,000 MTBF while a standard USB flash type device is usually around 10,000 MTBF. I wouldn't want to be running a Microsoft OS on a drive with that low of a MTBF rate. What may be interesting is a small Firewire drive (or 1st / 2nd gen ipod). They are very small and can easily be unplugged and taken with you.

It isn't even a close cousin to the USB stick drives that we are talking about! Then again neither is a USB hard drive (of which there are many). These device cannot be confused for the purpose of booting. As to data transfer rate, the IDE interface is much faster. A solid state device on a USB port is slow by comparison. Your testing with a solid state drive connected to an IDE interface should be very fast. I recently looked at some 6 GB solid state drives and they ran about $650.

I do think its possible. If you purchase 2 IDE adapters for flash cards, I believe you should be able to install windows on one and use the other for paging and powersdr. I am not saying I would want to do this, but I cannot see any limitations that would refuse it. My windows folder is 2GB and you can certainly buy bigger flash cards than that.

Re: [Flexradio] Disk-less Flex Radio
My employeer has hundreds of PC's running on compact flash memory cards with no hard drives and no fans. A machine with no moving parts has many advantages in an enviroment that may be less then office clean and running 24/7. There machines use a compact flash adapter that plugs into the IDE bus and the flash card plugs into it. All machines are running Windows XP Professional. The power supplies and motherboards are all fanless. The life cycle ratings of the compact flash cards are much longer than the hard drives.

Re: [Flexradio] Disk-less Flex Radio
Possible, but not practical. Flash has a limited lifetime on writes (10k to 100k, depending on the technology). Even if writes are load-levelled, paging on such a storage device would drastically shorten its lifetime over what you might expect. Most OS's allow paging to be disabled. This may or may not be acceptable for your use cases / applications. We had to go this way for Flash-based storage used in In-Flight Entertainment applications.

Re: [Flexradio] Disk-less Flex Radio
RAM is cheap. Use a big RAMdisk and load it, or at least the OS elements that need to be on a R/W filesystem, from USB or Flash media at boot. With a couple of gigs of RAM not being unreasonable today, I'd think you could make this work using a stripped down version of Windows something or other. It's a very different application profile, but embedded systems do this under FreeBSD and Linux all the time, with much smaller RAM footprints (my Soekris net4501 NTP servers boot from a CF image and run with a RAMdisk of less than 32MB).
