Memory or DRAM is the "working" memory of the computer. It's used to store data for programs (sequences of instructions) on a temporary basis.

Storage:

SATA

Storage Drives -- hard drives and solid state drives -- are the permanent memory for the programs and documents on your computer.

Data Transfer Rate is the rate at which data can be sent or received. This is determined by your motherboard. A drive with a higher transfer rate will only run at the rate of the motherboard's transfer rate.

Cache is a type of working memory that allows the drive to perform faster.

RPM is the rotations per minute of a hard drive which effects the speed of data transfer.

Solid State Drives are non-moving memory, so access speed is instant.

Chipset:

AMD M690G chipset

Chipset is a set of integrated circuits that have a specific purpose in a computer system, a group of microchips used together to perform a single task.

              Very impressive company! I like the ease of ordering. Crucial checked my computer automatically online to see what type of memory I needed and told me how much I could add to maximize my computer's performance. Crucial's automated system gave me several choices, but also made a recommendation for what they thought would be best for me. I was extremely pleased how quickly I got my order and how competitively priced the memory chips were from Crucial. I am a return customer of numerous times, having upgraded every computer I have ever owned with memory chips from Crucial. I would recommend Crucial to all my friends and family.
