"LIST PRICE" is the suggested retail price provided to Super Warehouse by our suppliers.
Super Warehouse makes no claim that these products have been sold or offered for sale at the list price.
The retail price in your area may be substantially different.
It is not possible for Super Warehouse to know if the merchandise has been sold at the list price
at any time, any where, as we sell our products over the internet both nationally and internationally.
"Total Savings" reflects the difference between our price and the supplier provided list price shown on our sites.
Since actual retail pricing in your area may be different than the list price shown on our site,
you may not actually realize a savings of this amount.
You may make a comparison yourself by checking the prices of your local retailers

The FastTrak SX4300 SATA 3Gb/s PCI-X RAID 5 controller delivers industry-leading RAID 5 performance at an unprecedented price/performance ratio. For companies running popular applications like web services, file/email servers, audio/video streaming and nearline storage, the FastTrak SX4300 opens the world of professional RAID 5 performance and data protection and combines it with cost-effective Serial ATA (SATA) 3Gb/s drives for the ultimate internal storage solution. Based on Promise's OEM-proven RAID 5 technology, the FastTrak SX4300 competes with SCSI RAID 5 controllers - at one-half to one-third of the price. The FastTrak SX4300 controller supports Serial ATA 3Gb/s drives and conforms to Serial ATA II, Extensions to SATA 1.0 specification with Native Command Queuing and Disk Activity LED headers support. Command Queuing increases I/O performance by intelligently reordering data requests so that the data can be accessed more quickly. RAID 5 implementation involves striping data and parity information (XOR) across the storage array. Since those parity calculations are so processor-intensive, RAID 5 controllers traditionally require a dedicated CPU to perform the XOR calculations and manage the array. Instead of adding a costly dedicated I/O processor to the controller, Promise's FastTrak SX4300 controller uses an integrated XOR engine for parity calculations, delivering extraordinary performance at a dramatically lower price. This approach takes advantage of today's ultra-powerful PC CPUs to manage the array and outperform traditional RAID 5 solutions.
