Why does the WD blue 500gb version have a 64mb cache and the 1tb version a 32 mb?

Is this going to affect gaming performance or performance in general should i buy the 1tb version? Are there any other similarly priced alternatives i should look into?

That sounds backwards. Generally the blue has 32mb cache and black has 64mb cache. Go to WD's web site and look up the model of those drives to verify the amount of cache. Gaming performance should be negligible due to the cache size, however, the blue most likely spins at 5400 rpm vs the black's 7200 rpm. The 7200 rpm drive will have better performance.

According to their website, all WD blue products have the same rpm (7200), but you're right about the cache size. An online retailer mentioned some weird specs on their HDD's which is what confused me.

There doesn't appear to be a Blue wd 500gb WITH 64mb cache max I can see is 32mb (model WD5000AZLX). Also older drives whether 500gb/1tb etc have lower caches than those released in the last couple of years. Always go by the model numbers to identify the specs on the manufactures website.
