Is there a noticeable difference between a hard drive performance with 2MB Cache and 8MB Cache. Drives of same storage capacity 160GB and same speed 7200 RPM?

I have a system running on a 2MB Cache 160GB SATA II 7200 rpm and just acquired a 8MB Cache 160GB SATA II HDD that is healthy. If the difference is not that impressive I will not bother, but if the 6MB of extra cache makes a big difference I will SWAP drives out and build CLEAN to the greater cache same storage capacity and RPM drive.

Found this info, but its apples to oranges with IDE / SATA drives and I am sticking with SATA II for both drives if I swap. http://www.tomshardware.com/forum/214255-32-16mb-cache-performance-games-audio


This drive here is in the system with 2MB Cache http://www.newegg.com/Product/Product.aspx?Item=N82E16822148692

And this is the drive I just got free and healthy according to crystaldiskinfo that has 8MB Cache http://www.newegg.com/Product/Product.aspx?Item=N82E16822148230

Couldnt find any info on any actual performance statistics to show if its just a 3% gain in data acquisition speed etc or something better like 10% or greater performance gain in how fast the drive can access and transfer the data.


* Maybe I just need to connect it as an extra drive and run a benchmark on both and compare that way, however the system only has 2 SATA ports and the other is used by DVD-RW. Couldnt find any benchmark info online like you find easily available for GPUs and CPUsI believe the difference between 8 MB and 2 MB will be too small to notice.
