Answer #1
I was going to suggest malware was making explorer.exe lag out , but if its a fresh install it may not be the case , try running all the updates you can as some fixes did help with stability a lot . what service pack are you on ?
plus a malware scan would not hurt either or a hijack this log , feel free to scan or post a log , myself or someone will gladly read it for you.

Half a second is nothing. When i load up my TB external i wait half a min or so cuz its full. I suggest deleting stuff you probably have them full, do disk defrag, allow disk indexing. Reading from HDs is always slow i dont get why people always expect instant speeds, get a SSD then things will seem faster.
