Specifications, Availability and Pricing
For such a little card the HighPoint RocketRAID 2310 has an impressive feature set. The first item that took me by surprise is the online RAID migration feature that allows you to add drives on the fly to expand your data capacity. For example, you can start out with a 3 drive RAID array and expand it to 4 drives without losing your data.
Another area that I found that goes above and beyond what most controllers in this price category are available with is the large selection of Linux drivers. HighPoint even offers the source code on their downloads page so you Linux gurus can tweak everything to exactly how you want it.
As far as pricing and availability go, the HighPoint RocketRAID 2310 is available at Newegg for 139.99 USD, 10 Dollars less than the MSRP. This puts the RocketRAID 2310 in the budget controller category, but HighPoint does offer even cheaper controllers according to Newegg. On the entry level HighPoint offers a 49.99 Dollar 2x SATA 1.5 controller and at the high end an 849.99 Dollar SAS controller that can run up to 12 HDDs.
