I'm trying to use ReadyBoost on my Windows 7 PC, and I didn't see any improvements on the performance since I used ReadyBoost for the first time. I tried to reach 2 GB of space on my USB stick to improve performance such as memory or temporary RAM for a while. What I don't know is that should I leave my flash memory drive all the time or delete the readyboost sfcache file. If I delete the cache file, what will the consequences be down the road?

Windows 7 Home Premium 64-bit
750 GB HDD
AMD Phenom X3 8450
Nvidia Geforce 9100

  1. it's never going to make a difference when you already have 4gb of ram installed. it only makes a marginal amount of difference if you have <1gb memory.
  2. I think (but I am not completely sure) that Readboost gets smarter after two or three days in operation. Maybe it --sort of-- racks up every call you make to your hard disk. Then, after some time, it is ready to respond to your requirements much faster.
