Posted May 24th, 2006, by rob-ART morgan, mad scientist As of this writing, the HighPoint RocketRAID series of Mac compatible SATA II host adapters are still the only ones that support RAID 5 at the card level. HighPoint has four PCI Express host adapters for the latest G5 Dual-Core Power Mac series. The RocketRAID 2322 is the only one of the three with external ports so we were anxious to test it. The RocketRAID 2322 has two mini-SAS connectors which enable you to support two of the HighPoint X4 four bay enclosures with Infiniband connectors. The big idea is that you have a single cable going to each four drive set. Unlike Port Multiplier boxes which would have the four drives sharing one 300MB/s channel, this mini-SAS to Infiniband scheme uses one cable to deliver a total of 1200MB/s bandwidth (four channels of data) to four drives. Also, the HighPoint X4 enclosure is one of the few which connects the drive directly to the backplane. For this round of testing, we used four (4) Western Digital Raptor 10K 150GB SATA drives in each of the three enclosures we used for testing. GRAPH LEGEND INSIGHTS AND ANALYSIS As indicated above, we used HighPoint's X4 Infiniband enclosure when testing the RocketRAID 2322. You may already have an investment in enclosures and cables for your SATA drives. You may not want to buy the X4 enclosure with Infiniband connector. Good news: HighPoint is offering an alternative cable that goes from the mini-SAS connector to four eSATA connectors which allows you to use conventional 4 bay or 8 bay SATA enclosures with the RocketRAID 2322. However, if you have Port Multiplier boxes, the RocketRAID isn't for you. It does not support PM. "HOT SWAP" RAID 5 IS NOT A PANACEA TEST SOFTWARE - DISKTESTER 2.0 We used it to sample the speed of the beginning (empty) and end (full) of our RAID set using a 4GB test file.
