SSD Cache. What is the benefit?

Recommended Posts

Posted · Original PosterOP

I'm looking to build my first computer. When looking at storage option you may find a 500gb SSD with a 512mb cache. What is the benefit of an SSD that has a cache vs not having one? Ex. Western Digital has an SSD with no cache will Crucial has an SSD with a cache. 

 

I am not trying to implement a server caching solution, just working with the basics here... Thanks. 


First build, nothing to see here...

In an SSD there's a map for different pieces of data in the drive. A cache-less SSD puts that into the slower NAND while cached SSD puts it in the faster and shorter latency DRAM (same stuff on system memory sticks). This means faster response.

Okay, so it should be a reasonable performance difference. Here are the two 500GB SSD's I've been looking at. Would it be worth an extra $10 dollars for the Crucial SDD. With all fanboy opinions set aside.
