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.

At Crucial, we understand something important about Mac computers. They're intuitive and easy to work with. Your memory should be too.

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. With over a decade of experience manufacturing and developing memory for Apple systems, we make it easy to find memory that's been designed specifically for your system.

Reliability for Mac systems.
If you're an Apple computer user, you probably expect intuitive, reliable performance from your system. We think memory should work the same way, too. 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.

Support for Mac systems.
Unsure how to install memory or have an important question about your Apple system? Let our team of experts help! With a tech-savvy team that's well-versed in Apple systems, we'll provide the technical support you need—no matter how old your Mac computer gets. From phone support, videos, FAQ articles, and do-it-yourself guides, we've got the resources you need to keep your system up to speed.

Crucial—quality you can depend on.
Crucial is a trusted name when it comes to DRAM, and that's no coincidence. As a brand of Micron, one of the largest manufacturers of DRAM in the world, we work with our engineers to design, refine, test, manufacture, and support our extensive line of memory modules. With a product portfolio that includes more than 250,000 different DRAM upgrades for more than 50,000 systems, we've got one specifically designed for your Mac system. For more than a decade we've kept Mac computer owners happy with high-performance memory and outstanding customer service. No matter what type of Mac system you have, we've got a compatible solution.

The right Apple Memory

Comments about Crucial 4GB Upgrade for a Apple iMac 3.06GHz Intel Core 2 Duo (21.5-inch - DDR3) Late 2009 System:

I ordered memory from another vendor before I found you guys. Their memory was suppose to work, it didn't. I had to pay to send it back. You company has a tiny client to run on my machine and it tells me what memory will work. It worked right out of the box and has made a giant leap in speed on my machine. I do PC repair and I did not know that OSX needs more memory than the 4 gig that came from the factory. I added 8, now with a total of 12. Four may get you by on a PC not OSX. I can now keep my iMac a few more years.
