How to Connect Your SSD

Computers have used one form of hard drive or another for decades; nobody wants to reload everything from scratch every time you boot up. While the technologies and interfaces have changed, the basic principles have not.

What is SATA?

SATA, or Serial ATA is a computer storage interface that replaced the earlier parallel ATA interface. Although parallel protocols allow for more data to move in a single transfer, serial protocols are able to operate at higher frequencies due to reduced cross-talk and other factors. When it came to hard drives, the increased frequencies were able to greatly outweigh the narrower pipe. There have been three main revisions of the Serial ATA standard:

  • Revision I: The original implementation, operating at 1.5 GB per second.
  • Revision II: The first major revision, added native command queuing and doubled transfer rates to 3.0 GB per second.
  • Revision III: The third iteration doubled transfer rates again, this time to 6.0 GB per second.

What About SSDs?

Solid state drives were originally for use with the same interfaces as existing drives. An internal SSD was a drop-in replacement for a SATA-based HDD, so it needed to connect to the computer in exactly the same fashion so that the computer could take advantage of the greater speed provided by NAND instead of magnetic storage.

  • Physical Interfaces: There are three main interfaces used with SSDs; SATA, PCIe, and M.2. The first is the traditional hard disk interface, while the second uses the same interface as expansion cards. The third allows for very small form factor drives using a dedicated connector.
  • Data Protocols: You can have 2.5-inch SATA III, mSATA, and some M.2 SSDs that all use the same SATA-based data protocols. Some Samsung EVO SSDs use NVMe, or Non-Volatile Memory Express protocols, which are much faster than even SATA III but not as widely supported.

Using a Solid State Drive

One advantage of a fast drive like the Samsung 850 EVO is that you can also take advantage of proprietary protocols like the company's RAPID mode, which utilizes RAM caching to boost the already great responsiveness of V-NAND solid state storage. Putting your OS on a 960 GB SSD can have a huge effect on your existing system. Boot times drop significantly from spinning disks and overall responsiveness does the same. Any computer is only as fast as the slowest link in the chain, and when you can get your primary storage up to similar speeds as earlier generations of RAM you can really see programs opening faster. Your least productive time is always that spent waiting for the computer.
