If I go for the WD with 32 MB Cache over the others which only have 8 MB Cache, will I notice a big difference in performance? My primary hard drive is identical to this drive, only difference is the cache is 8 MB (http://www.newegg.com/Product/Product.aspx?Item=N82E168...). If I get the 32 Cache one, should I make it the primary drive? Is the performance difference worth the extra 7-8 bucks in shipping?
This is my laptop:
Dell Studio 17 (1735) Laptop: Intel Core 2 Duo T5750 (2.00GHz/667Mhz FSB/2MB cache)
4 GB RAM (667MHZ 2X2GB)
Western Digital Scorpio Blue 320 GB 5400 RPM 3.0 Gb/s 8 MB Cache
ATI Mobility Radeon HD 3650
Windows 7 Enterprise
