A while back I posted that I was using NTFS junctions to offload some program files to a high speed flash drive. I ran into a road block when there a slight shortage of space, so I decided to NTFS compress the drive. Here's how bad the fragmentation is: picture What's interesting is that it doesn't seem to slow anything down. Even with NTFS compression and brutal fragmentation, it can still load Excel, Word, Powerpoint, and Photoshop in a very short time. Up until now, the biggest problem with NTFS compression was not the fact that it requires CPU power, but the fragmentation forces the drive to look all over the place just to find everything. Flash/SSD is not so heavily affected by fragmentation, so the only real concern is the CPU demand. Can someone else check this for me? If you have an SSD, all you need to do is NTFS compress your Program Files directory and see if performance noticeably decreases.
