Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found here.

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 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.

Part Number: ST500LT012
Thinner chassis for high-end lines.
Seagate integrators and OEM customers are faced with an increasing demand for thinner yet fully functional mainstream laptop computing solutions. Until recently, the only option for these thinner solutions revolved around high-priced, slow performing 1.8-inch drives and high-priced, fast solid state drives. Because both storage types were costly options, system designers had no choice but to build thinner chassis only for their high-end lines. Enter Seagate ingenuity.
