"I was very skeptical, having 6GB of ram on my 8730w laptop running 64bit Windows 7 RC. But, since SD cards is so cheap now, I went out and bought a Panasonic Class 10 (22MB/s) 8GB SD card and put it into my laptop and enabled ReadyBoost. To my surprise, it was quite a noticeable performance gain. One must understand though, that it's a cache kind of performance gain, meaning that you will notice a quite substantial improvement the 2nd, 3rd time you start an application. Nevertheless, I'm most certainly keeping the SD card in my laptop, it's ""hidden"" away and doesn't stick out like an USB stick."
"We just made a detailed comparison on two computers: one with Windows 8.1 and one with Windows 7.
The improvements we measured when enabling ReadyBoost on a system with low amounts of RAM, are the following:
Opening media files like photos, music or video is slightly faster (approximately by 2%). The loading of web pages and the use of Office applications is slightly faster (approximately by 2%). Your system's boot timings are improved (up to 7%). Your most used applications start faster (by 10 to 15%).
ReadyBoost had no positive impact when playing games or running applications that are CPU or GPU intensive.
You can find the detailed testing procedure plus all the results, here: Does ReadyBoost Work? Does It Improve Performance for Slower PCs?."
"It does improve performance by storing program launch data which RAM does not, or which is cleared when not needed, or via system powerdown.
The simplified results of those few tests that were performed have been used by every website since, and its rubbish (Google it and 99% will tell you it offers no performance increase, few have actually tried it), totally misleading.
I've tested myself using Windows 7 (x64), 9 GB DDR3 (only ever reached about 6 GB in use) and a 16 GB Sandisk micro SD card.
The speed programs launched improved drastically, from 3-5 seconds to under 1.
That's where the performance gains are, and that's why it was created. Tt will not give read or write performance increases for other files a program might use, it is dedicated to program launch.
It always seemed to me to be sort of a kludge. If you want your applications to start up fast, put them on a SSD.
I did, a small cost effective one :) we all know a 128 GB SSD is not enough for windows over a couple of years use, what with program updates and installations, anything over that has scandalous prices. Not to mention the serious bugs that have sprung up with a whole host of SSDs. 16 GB card cost around $15 at the time, much more affordable option."
ReadyBoost provides an enormous advantage when you are writing alot to the hard disk. I have a fairly decent machine. 5GB RAM with a quad-core 3GHz processor. With ReadyBoost I often see a tenfold increase in write speed when performing I/O intensive tasks like copying large amounts of data of compressing/decompressing archives. When not writing alot of data I do not notice any performance benefit, but I understand that if your system is short on memory, ReadyBoost can speed up evn the most mundane tasks.
"I have a class 10 50mb/s 16gb SD card the card reader in my laptop is usb3 driven. Even with 4gb of ram, the performance is outstanding... That being said, a USB 2 or class 4 SD card won't do a thing. I tested using a random class 4 SD card I had lying around and the performance was negligible. I will upgrade to ssd later. Gotta remember it's cache not ram and not storage. I have windows 8.1.
Couple of things to make the best of readyboost.
Format to exFAT and not NTFS, use the whole device, the more the better. exFAT does less sequential checking therefore faster. You don't need a journaled file system for 1 big file. There's nothing to journal lmao. Oooo 1 file... Performance exFAT wins.
Make sure it's a class 10 SD if you plan on using SD. Class 4 will offer nothing.
Make sure you're using USB 3. SD or otherwise. I chose SD because it's a laptop and I don't use the SD port. USB 3 USB stick in my desktop.
The bigger the size the better. I saw the biggest performance when copying files while using applications. Basically it allows me to install and copy things while working on other stuff without hitting a wall. Windows will also page to it if need be like when using the hard drive, it will cache paging parses.
The longer you use it the better readyboost and superfetch work together to be the best it can be."
