[QUOTE="Andy Ful, post: 812838, member: 32260"] For me, after looking at several benchmarks and using WD for 4 years: [LIST=1] [*]It is far away from 3-rd party AVs while copying many files and installing/uninstalling most applications. The same if someone tries to compile executables, comparing files in folders (binary comparison), etc. [*]It is usually very fast (one of the best) when launching most applications, downloading most files, web browsing, gaming. For some very suspicious files can be slower due to Cloud-delivered protection (up to 10 seconds on default settings). [*]There is a well-known cause of slowdowns (not optimized file caching), so everything that depends on it will be slower. [/LIST] If the user feels WD in another way it means that there is a kind of incompatibility, probably due to hardware drivers. On some computers, WD can be slow and the cause is not known - not related to processor speed or amount of RAM. [/QUOTE]
