=Introduction=
In order to have our '''Koji ''' Build Farm run as efficiently as possible we needed to find out which form of data storage would be the fastest overall. The candidates were:
* '''PATA ''' Hard Drive connected via USB* '''NFS ''' share from HongKong* '''iSCSI ''' network connection to HongKong
===What results are we interested in?===
There are 3 main results that we are interested in when rating storage performance.
1. '''Read: ''' The amount of data that can be read from the storage medium per second.
<br>
2. '''Write: ''' The amount of data that can be written to the storage medium per second.
<br>
3. '''Access: ''' Time required for a computer to process data from the processor and then retrieve the required data from a storage medium.
===Cost===
Since '''NFS ''' and '''iSCSI ''' are both network storage solutions they have no cost in themselves, but rely on network storage on a remote server. This price is simply the cost of the drives that will be installed in the remote storage server. A USB connected PATA or SATA drive requires both a hard drive and a '''PATA/SATA ''' to '''USB ''' interface such as an external drive enclosure.
* '''NFS: ''' Free (Uses existing storage)* '''iSCSI: ''' Free (Uses existing storage)* '''USB PATA: ''' ~$100 CAD
