Performance: 32MB vs. 64MB Cache - Noticeable?

I'm looking to replace two of my 3.5" internal HDDs with two 2.5" drives for mounting behind the motherboard

 

Currently looking at two of these:

HGST Travelstar 1TB 2.5" 7200RPM HDD

 

However, this drive has 32MB of cache, compared to 64MB of cache on my current WD blacks. 

 

Is there a significant performance difference between 32 and 64MB? One drive will be used for data, and the other for game installs. Is there any reason I shouldn't go through with this?

 

I've search around the webbernet for 2.5" 1TB 7200RPM SATAIII drives with 64MB of cache, but they only seem to exist in SAS HDDs, something I know nothing about.

 

-----------------------------------------------------------------------

 

My other option (I guess) would be to get two 1TB 2.5" SSHDs

 

This would be the one I'd get if that's the case:

Seagate Laptop 2.5" 1TB Internal SATAIII SSHD 

 

But my question is, is that drive actually 5400 RPM? Wouldn't a SSHD be faster than a 7200 RPM drive?

 

Thx
