Readyboost using SD card in 5760?

Has anyone here successfully found an SD card that will enable ReadyBoost to work in Vista? Just curious, as I am unsure whether or not the built-in card reader is fast enough to use ReadyBoost with.

If you have gotten ReadyBoost to work with an SD card in the 5760, which brand/speed/model # of SD card did you use?

Thanks!

 

Just curious why use readyboost rather then buy actual ram? SD memory has a limited number of r/w before it will die, which means you will need to replace it long before real RAM would die.. It's also slower then real ram is.

 

I didn't mention anything about not using actual ram. I have 2Gb of RAM. But, since it is a new feature in Vista, I want to try it out. I am not expecting my computer to transform into some super AI that writes my papers and does my laundry for me. I don't expect any sort of HUGE performance boost. But, I want to try it.

I see that 2Gb SD cards are around $30 or so. I am willing to spend $30 to try something out. If it doesn't work, I've got a 2Gb SD card for my camera.

But before I make my $30 purchase, I would like to make sure of 2 things:

1. Is the built-in card reader in the 5760 capable of writing at sufficient speeds.
2. If yes to the above question, what SD card has worked for you in your 5760?

 

To 1) , I don't the card reader is the problem (since AFAIK the interface for the card reader is PCI Express which has a much better bandwidth than the USB one's) nah, the problem is the SD card itself.I think (if it's compatible which I think it is) get a 150x card or something.

 

My question wasn't so much directed at you, but I keep trying to find a real reason to try it.. It just seems sort of gimmicky to me. Like MS knew that O/S was gonna suck so they tossed in this extra feature to give people hope..

 

I've only used a jumpdrive and it's hard to find them that actually say Vista compatible. I bought a PNY and it said it was Vista comp but the password software on the drive wasn't compatible.

 

I've tried 6 different SD cards and 3 USB flash drives for use as Ready Boost memory using the SD card slot and USB port in my Dell 1520 notebook. This is one of the few SD cards that would actually pass the memory speed test in Vista.

It's an OCZ 4Gb Hi-Speed 150X. Got it at NewEgg.com for $60 delivered. Also tried a 155X 4Gb Ridata SD card but it wouldn't pass the Vista speed test which was kind of weird. Have an Ultra 512Mb SD that benched very well and it doesn't even have a rated speed. Go figure...

Both of my USB flash drives including the Patriot Xporter XT which is supposed to be 200X and one of the fastest flash drives on the market couldn't even keep up with the little 512 Mb SD card.

I also tried:
4Gb Ridata 155X SD Card- Wouldn't pass the Vista test
128 Mb Kodak Picture Guard SD Card - Wouldn't pass the Vista test
2Gb Ultra Hi-Speed SD Card - Wouldn't pass the Vista test
2Gb Ridata SD Card - Wouldn't pass the Vista test (really a dog...)

For Ready Boost you need:
2.5MB/sec throughput for 4K random reads and
1.75MB/sec throughput for 512K random writes
