windows vista ready boost?

it's not a replacement for ram, not at all

basically it's used as a fast pagefile




if you've got 2gb ram, don't get a 2gb usb drive thinking you'll then have 4gb :p

even if you've got 8gb ram, having a readyboost drive will help in some situations (albeit a small amount)
 
oh right, i just thought it was like a replacement, eg. a 2gb pen drive was like 2gb RAM. but obviously you still need some RAM in the computer for it to work so it's not a complete replacement
 
no

it's not at all a replacement

it's slow as hell compared to ram like 1000x slower, it's used for temporary paging only
 
Yeah it's no substitue for physical ram. Get's addressed MUUUCH slower, but then as said can be used for a page file quite nicely.

k thanks, so is it still worth having a pen drive just left in the back on the computer for that purpose? or it's such a minor difference that it's not worth it
 
i wouldn't actively go out and buy one if you're after a performance boost.. i've got one, just used a £7 one from the net, a sandisk 4gb or something

how much ram do you have?
 
are you running 32bit or 64bit?

32bit can only see around 3.5gb ram, it's a limitation that all 32bit os's have


hence why MS should have made vista, x64 only
 
Readyboost makes quite a difference on my lappy, but that's only got 2GB ram and a 5200rpm drive. Switching apps, opening apps etc - it's all just a touch snappier.

On my main rig with 4GB ram, readyboost makes naff all difference.
 
I've got 1GB in my laptop, and thought I'd be clever and get a 2GB SD card so it doesn't protrude from my machine. Vista accepts the card as fast enough but it made no difference - then I learned that the item could do with readyboost certification to work properly. So make sure you get a worthwhile device if you go the readyboost route......
 
Indeed, readyboost in not a replacement for RAM as it's much slower, but it's much faster then paging stuff off to the HDD and so that's the primary reason for it. IIRC, even if you have a large amount of RAM, it'll store some superfetch files there which can help booting times.
 
The biggest use of readyboost is for those who don't leave their PC on all the time.

Readyboost enables you to keep a non-volatile copy of the superfetch information rather than spending time loading it all into ram each time.

That the memory stick is slower than ram isn't the issue, it's quicker to sequentially read from the memory stick than to randomly read from the hard drive at each start up.

For the £7 a decent sized memory stick costs, the boost is worth it.
 
just got a corsair voyager 8Gb flash drive, Vista says it is too slow for readyboost - yet my 4gb corsair voyager worked fine. Any ideas? Or is the 8Gb much slower than the 4Gb?

I never got any Voyager to run (early ones, some say newer ones are faster) only Voyager GT's.

Here, it has very little to do with MB/Sec, infact 2MB/Sec is enough.

Again Readyboost replies on Timings and Delays and Seeks, not overall MB/Sec.

I would not use Hack as a proper ReadyBoost Drive is cheap

" Q: What perf do you need on your device?
A: 2.5MB/sec throughput for 4K random reads and 1.75MB/sec throughput for 512K random writes

Q: My device says 12MB/sec (or 133x or something else) on the package but windows says that it isn't fast enough to use as a ReadyBoost device... why?
A: Two possible reasons:
The numbers measure sequential performance and we measure random. We've seen devices that have great sequential perf, but horrible random
The performance isn't consistantly fast across the entire device. Some devices have 128M of lightning fast flash and the rest of the device is really slow. This is fine for some applications but not ReadyBoost."

For now 4GB is the MAX you can use so don't waste your 8GB on it.
