guess we are just going to have to disagree over the values of higher cache on hard drives

Or you can change your mind

Most people on fitting a new drive with a larger cache assume the cache is responsible for any performance increase.

The reality is that the HDs internals are likely to be vastly improved when compared to a similar spec older drive (Design age not HD age). Spin speed, ATA spec and cache size etc have less impact on data read/write speed than

Data Density. Getting a drive with 2 platters vs 5 platters that holds the same amount of data. The higher the density the faster the read/write.

Disc access. The faster the heads can move from the inside track to the outside track, the faster it can access files.

I'm not saying that a larger cache doesn't help......... Just that any big increase in performance that most people get when installing a drive with a bigger cache is usually down to the drive as a whole being better.
