Roswill 10 port USB 2.0 hub Update: 10.4.2013

With the recent huge drop in Block Erupter price, we decided to add 200 erupters to our own mining farm. While the Anker 3.0 USB (the new 9 port hub) is still our favorite, we noticed the price increase in most of the top quality USB 3.0 hubs from Amazon. Needless to say, adding couple hundred erupters can be pretty costly at $60 a pop! So we looked around and bought in some cheaper solutions to try it out on the erupters.

Our of the 5 different hubs we tried, only 2 was worth mentioning for GOOD and BAD reasons. The Juiced system 7 Hub (we tested 4 of them) kept having unknown issues with seeing the erupters even though it has more then sufficient power for 10 erupters. We end up returning all 4 hubs. Best USB Hub for Block Erupters any high expectations we first tested it with 5 Erupters and ran for 24 hours without any issues. We then added 2 more erupters to the hub and another 24 hours went by without any problems! We managed to snatch up 10 before they were out of stock, and magically they were back in stock the next day at $22.99. Even at the current price of $24.99 it’s still worth it!

Few things you need to know before we compare the different USB Hubs out there for your Block Erupters.

A single Block Erupter will require 2.5VA. A good point of reference when purchasing your USB hub is take a look at the box or the power adapter of the USB Hub. If the box or adapter says 5V 4A, then you can power 20VA worth of Block Erupters. 20 VA / 2.5 = 8 Block Erupters, If the hub you’re buying is a 10 port USB hub with a power adapter that says 5V 4A then the maximum Block Erupter you want to plug into this hub is 8.

* Note that it’s a good practice when possible to reduce the maximum Block Erupter allowed by 1 just to prevent overloading your USB or burning out the AC Adapter.
