Memory:

DDR PC3200

Memory Type: DDR PC3200, DDR (non-ECC)

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.

    I needed to add more memory to my MAC. When I called Apple I got this great customer service guy who told me what I needed to upgrade to Apple's Leopard Operating System. The first step was going to Crucial.[@]. Honestly, the guy at Apple made it super easy for me. He told me exactly what to buy on your site and then he sold me the Leopard program. He told me how to install the memory and then gave me key points to remember when I was installing Leopard. I think this kind of partnering is rare to find and was so beneficial to me. I feel like I have whole new computer.

          It was e breeze to install and a decent overall performance but wish there more speed in screen re-draw and multitasking. Maybe the problem is in my iMac (getting old) but I would consider purchasing another product again in the future.
