Readyboost

Does anyone actually use readyboost on their computer, and have you noticed a difference in performance when using a fast USB drive as extra cache?

I have lots of USB drives around my room, but I don't bother using them in readyboost mode. Do you think I'd notice an improvement in performance if I used one?

I did use it with Vista for quite some time, but only because I use my USB drive as one of my backup devices and leave it plugged in a lot. I didn't notice a huge difference with my 2GB of main memory, but on my other halfs older PC with 1GB of ram there was a small improvement

I do actually, I know it has been said that past 2GB of RAM you don't see a big improvement, but that's a lie for obvious reasons. Your RAM doesn't write your HD's cache, your HD does... therefore the extra boost from the FlashDrive improves no matter what RAM you have.

I have 8GB of RAM, and I only just put a 2GB FlashDrive in for ReadyBoost, and It cut my load time for Photoshop CS3 from 4 seconds down to 2 seconds. Browsers and folders open literally instantly. Even google earth opened in half the time (from 5 seconds down to 2.5 seconds) And this is just a measly 2GB FD plugged into my keyboard lol. I wanted a few bigger ones for work anyways, so I am definately going to use a larger one for ReadyBoost.

Quick question - Is ReadyBoost still limited to 4GB because of the Fat32 File size limitation?

And if 2GB readyboost helps a 8GB memory system - Whats all the talk about readyboost being 1.5 times your system memory?

Readyboost can help a computer run Vista with 512mb RAM, but considering 7 has so much less overhead I'd think there would be no need for it to even exist in 7.

After 1gb of RAM or so, ReadyBoost will only decrease performance.

^^ Clifford: Just reformat your flash drive in NTFS. I believe XP and on would only format in NTFS but in 2000 you could pick FAT32 or NTFS, but I might be getting this backwards. I know that I had some flash drives that I first formatted in NTFS -- on a Windows 2000 machine and had no trouble.

If you can't get it to format in NTFS from the window, try using the command prompt, I bet that would do it.

But I do believe FAT32 goes up to something like 64gb, where FAT16 goes up to 2gb, if memory serves me right.

Thanks fps_dean for the post but thats not the problem - The problem is the max file size under fat32 - The max file size is 4GB - ReadyBoost uses a file much like the pagefile on C:\ - The only way around this is for readyboost to use more than one file or use a NTFS file system on the USB stick. I was wondering if someone has already looked this up to see if the limitation still exist under Windows 7

Oh yeah I completely forgot about that. However, if you format FAT32, then that will always be a problem regardless of what OS that you use. In this day in age, with more and more NT based Windows (98 is pretty much dead), Microsoft can assume everyone can read NTFS, so I would not see them finding a way around it -- it's just not worth the time spent.

The easiest way to tell is throw a flash drive in there and see if it tries to create multiple files on the flash drive.

Another reason I would guess not would be writing 2 files in parallel to a USB flash drive is most often much slower than writing them sequentially...

Hi guys I found my answer and wanted to share it with you

The updated Readyboost in Windows 7 will see several advancements. The 4 Gigabyte restriction will be lifted which essentially means that flash drives with larger capacities can then be used as additional cache. The limit to one Readyboost device has also been removed which gives users the possibility to use multiple flash drives as additional caches in Windows 7

While I really don't see the point of doing all those changes for no benefit (remember how slow usb drive access is, and how long it would take to write over 4gb), that is interesting to know.

Readyboost should help some of those poorly equipped netbooks and laptops, but that'd be the only time I'd ever recommend it. As many have said it can generally have a negative performance impact on a moderate to high-end desktop that has 2GB or more of RAM.

USB 2.0 flash drives are limited to 35MB/s read speeds at best, but most do not even come close to this best case scenario. By comparison any modern off-the-shelf desktop hard drive will reach 80-100MB/s or still more by using the outer edges of the disc (ie mostly empty). Either way, the speeds of RAM can typically be anywhere from 7,000 to 20,000MB/s to put those numbers into perspective.
