poolhd logoA new Drive Extender offering is on the market.  PoolHD from Anvil AG http://poolhd.com/ is making a run at the expandable storage market with PoolHD and a promise that it will be simple, fast and infinite.  The first version was released June 18, 2013.  With a starting price of $12.95USD and a Windows Home Server 2011 / Windows Server 2012 Addin scheduled to release on June 26, 2013, the offering looks interesting.

I am using a Window 7 VM with 2GB of RAM on top of Microsoft Windows Server 2012 Standard w Hyper-V role.  The VM has a 60GB OS Drive with 4 x 50GB Data Drives.  Disk 1 and 2 are VHDx Dynamic and Disk 3 and 4 are VHDx Fixed.  Downloaded the 30 day trial.

It’s a very simple install. With few install options, I select all the defaults. It goes very quick.
