SATA 1.0 could transfer data up to 150 MB/s (megabytes per second), SATA 2.0 doubled that to 300 MB/s, while SATA 3.0 doubled the transfer rate again up to 600 MB/s. SATA is available in a number of different flavors, each of which provides progressively faster data transfer. It’s been around since 2003, and offers great advantages over older standards in that it provides for faster data transfer, native hot swapping (a drive in a RAID array can be replaced while power is applied to the array), and reduced cable size and cost.

SATA stands for Serial AT Attachment, a computer bus interface that connects computer host bus adapters to HDDs and SSDs. You know those flash drives for transferring data between computers? Just think of SSDs as flash drives that utilize a much faster interface inside a computer, and you’re pretty close. The memory used in SSDs is usually NAND-based flash memory. One interesting thing about Apple’s SSDs used in some of its newer devices like the 12-inch Retina MacBook is that they can be made in non-traditional shapes to allow for much thinner designs. So with the advantages, why aren’t all computers using SSDs? At the present time, SSDs still cost more per unit of storage than HDDs. Since no physical read head needs to move across a rapidly spinning platter, access times are much faster as well. SSDs have no moving parts, which makes them more resistant to physical shock and allows them to run completely silently. While HDDs use a spinning magnetic platter to store data, SSDs are Solid State Drives that use integrated circuit assemblies as memory to store data persistently - that is, they can store data even when power is shut off. The two most popular and widely-used rotations speeds are 5400 RPM (revolutions per minutes) and 7200 RPM.
The faster the rotation speed of an HDD, the faster it can read and write data. As you’ll see later on in this post, there are a variety of interfaces made to connect computers to external HDDs and SSDs.

Most current internal HDDs use a SATA interface, while pre-2006 Apple laptops and most PC laptops use ATA type drives.

The larger 3.5-inch drives come in capacities up to 8.0TB (terabytes) and are used predominantly in desktop machines or external backup drives, while the smaller and lighter 2.5-inch drives are available in capacities up to 2.0TB and are made for use in laptops or portable backup drives. The drives are encased in airtight aluminum, with usually just one connection that’s used for both supplying power to the drive and for the transfer of data to and from a computer. HDDs usually come in two different sizes - 2.5-inch and 3.5-inch. Most computers come with HDDs built-in, although SSDs (see SSD section below) are becoming more popular. HDD stands for hard disk drive, meaning a device that uses a spinning rigid platter for magnetic storage of data. Cutaway view of internal HDD showing platter and read/write mechanism Our job is to inform and educate, so let’s take a look at what some of the more common acronyms and terms mean. Well, that’s why we’re here at The Rocket Yard.
Take a look at the home page - even the new home page - and if you’re new to the world of storage upgrades and solutions, some of the terms used might be a bit mysterious.
