Port Multiplier Enclosures & Accessories

Port multiplier enclosures feature a single eSATA port per 5 drives and work with port-multiplier-capable controllers only. They are a distinctly different setup from our multilane enclosures.

On the plus side, controller and cabling cost is very low. You can have 5 or 10 bays in a tower enclosure as opposed to 4 or 8 with our other solutions. If necessary, it is possible to convert the connection to USB via our eSATA to USB adapters. It's a very economical way to have 12 or 20 drives in a single enclosure.

On the other hand, performance in RAID modes will be limited compared to multilane units. You will be limited to non-caching controllers and you will not be able to use RAID 6.

At PC PitStop we build our own port multiplier enclosures and pair them with several different controllers from Areca, Highpoint or Silicon Image according to your needs. Give us a call and we'd be happy to discuss the details with you.
