FAQ & Section Info
Why buy a 3.5 hard drive for my desktop?
If you're building a new computer, swapping out a dead or dying drive, or upgrading your PC's storage capacity an internal hard drive is still the way to go for most. Even though SSDs have become more and more popular in recent years because of their access speeds, most builds still utilize a standard or "rotating" hard disk for bulk storage needs. The reason for this is that these drives are much more affordable, more reliable in many ways, and still offer very fast read/write access speeds. A typical build may feature a smaller SSD as the primary boot drive on the PC alongside a hard disk drive for storage of files, media, etc.
What is the best brand in hard drives?
We recommend Western Digital, Seagate, Toshiba, and Hitachi in that order.

What is the RPM rating on a drive?
the RPM rating on a hard drive or Revolutions Per Minute tell you how fast the internal platters on a drive are spinning. As a general rule, the faster the platters on a drive are spinning, the more quickly the read/write head can access the data and so your performance improves. When choosing between two drives, if your aim is speed then choose the faster spin rate.
How is hard drive performance rated?
Performance is rated by data transfer speed which is typically measured in MBps or Megabits per second. Higher RPM drives typically have faster transfer rates.
What is the size rating on a hard drive?
When shopping for a hard drive you'll always see the drive capacity listed as a number followed by the unit of measure - typically GB for gigabytes or TB for terabytes. These numbers tell you how much storage space the drive has. A terabyte is larger than a Gigabyte, with 1 terabyte equal to 1024 gigabytes.
How much storage do I need?
Though it is mostly a matter of preference the best method to determine the amount of storage you require is to check your current hard drive's free space. A typical consumer user should be safe with between 500GB to 1TB of data while more media heavy users should seek an excess of 1 terabyte or more.
