Super high write speed with Samsungs Magician trim optimizer, Which trim optimizer to use? Windows 7

[BeyondSpace]

Hello, I just bought a brand new Samsung 840 Pro 128gb ssd and tested the write speed with Crystaldiskmark noticing 442.4 Mb/s then after some gaming and tested it the next day, my write speed dropped to 354.7 Mb/s. Does anyone know why I would lose so much speed in one day? I play Second Life so the game is constantly writting to my ssd. The other thing is how can I use windows 7 Trim to test the speed difference? It's enabled but can I manually trim the drive? And if I do, will it decrease my performance if I do it once a day? I installed Samsung's Magician software and ran the peformance trim optimizer and my sequential write speed jumped from 354.7 Mb/s to 467 Mb/s and the read jumped from 500 to 545 Mb/s. Which is the best to use? Should I disable windows 7 Trim and use Samsungs Magician Software?

I don't even know how often Windows 7 trims the drive to optimize it's speed but I had a Kingston Hyperx 3k 120gb drive for 6 months and rma'd it once, then got a replacement, and returned the second one for a full refund because the write speed was 140 Mb/s on both drives. It was horrible, my 7200 rpm seagate does 140 Mb/s.

Thanks for the feedback.
