Acomdata is a privately held company in Ontario CA that markets external desktop hard drives, hard drive enclosures and accessories such as cables, adapters, PC boards and carrying cases.
Acomdata is a hard drive brand. They offer a full range of products. Most of the ones that I have seen are external and portable. They seem to have good prices on a wide range of products. The hard drives are from 160 GB to 2 T. The prices range from $89 to $222.
