Solid State Hard Drives (SSD)

The speed of any computer system is determined by the slowest part (the "weakest link") of the system. One of the slowest steps in your system is the physical transfer of data to and from the hard drive. This transfer requires that data be "written" and "read," which is a mechanical process (in contrast, data moves throughout your computers electronically, at close to the speed of light). The writing and reading from a hard disk slows down even further when there are many users on one system. At times the system may slow to a crawl, or worse, create a long cue of data waiting to be processed, which leads to a crash.

New solid state hard drives (SSD) have appeared on the market with the capability to move information electronically rather than physically. Praxis runs dramatically faster on these solid state drives.

We recommend the following SSDs to Praxis users:
