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.

Compatibility for Mac systems.
Engineered to be compatible with your Apple® system, Crucial Memory for Mac takes the guesswork out of a memory upgrade. Since Apple systems often have very specific memory requirements, including particular component densities, speeds, and SPD programming specifications, it's important to buy your memory from people who know Apple computers inside and out.

For each module we manufacture, we send it through a rigorous testing process to ensure that you're getting a reliable, high-performance memory solution. Every module that leaves our doors has been extensively tested at the component level for voltage and temperature resistances, signal integrity, and software compatibility. The result? Reliable memory that meets or exceeds Apple's own memory requirements. With the latest lead and halogen-free technology and built-in thermal sensors1 to help control your system's cooling, Crucial Memory for Mac features advanced innovations.

      Pros

      • Easy To Install

      Cons

      • Confused By Options

      Best Uses

        The RAM was really easy to install. It also shipped really quickly which was excellent. The only thing that was bad was that I was worried I would pick the wrong RAM for my iMac from the list. There were so many options. It did not help that I had not yet received the iMac, so I couldn't use the software approach of determining which RAM was appropriate.

            We upgraded two new 27 inch imacs to 24GB of RAM and the things are flying now. Several Adobe programs opened simultaneously run without a hiccup. Too bad the machines came with 8GB, otherwise we'd have upped it to 32..

              The key to getting the memory you want is knowing exactly what fits in your machine. How obvious is THAT? This is why I've never had a problem buying third-party RAM. Crucial has a great reputation, and why wouldn't one buy directly from the manufacturer rather than paying a heavy mark-up to buy it from the computer-maker?

                      • Easy To Install
                      • Much less expensive
                      • Works like a charm

                      Cons

                        Best Uses

                          I would recommend this. Works well. The only issue is that for installation, the new 27" late 20112 has new installation features. Those had to be found somewhere else. BUT, Apple has made it so easy to install new memory in this machine that it's ridiculous.

                          NOTE: you will have to put more pressure than you are comfortable with to get the memory to snap in.

                              The only "issue" I had was getting the hatch open on my iMac. I found that I had to press the release button deeper than I expected. Once I figured that out it went smoothly and quickly. Should take only 5 minutes.

                                    I am very pleased with the Crucial RAM modules. As a computer technician myself I took a long hard look at the modules and compared it to the factory modules and the quality of what I could see looked just as good as the factory modules. The value is excellent compared to the price of the OEM module.
                                    The hardest part is understanding how memory is arranged in the late 2012 iMac 27" and I wanted to ensue it would run in dual channel memory mode, if the RAM is not installed in the correct order the memory manager runs in compatibility mode which affects performance. I moved the original 8GB modules to the vacant slots and put the larger modules in the slots originally filled by the original modules.
