Maxtor's Central Axis Business Edition is a dual-drive follow-on product to the single-drive Central Axis [reviewed] introduced earlier this year. Aside from supporting two drive configuration modes—Linear (JBOD) and RAID 1—the Business Edition (CABE) is feature-for-feature identical to the original Central Axis.
Physically, the CABE retains the pyramid form factor of the original CA, but since it is stretched to accomodate two drives, it looks more rectangular. Figure 1 shows a diagram of the front panel, which contains only three status lights.

Figure 2 shows the rear panel, which sports two USB 2.0 ports; one more than the CA.

Since the CABE is meant to be easily opened for drive replacement, I was able to get some good internal photos. Figure 3 shows the CABE with its cover removed and two Seagate Barracuda 7200.11 ST31000333AS 1TB drives in place.

Figure 4 shows the drives removed, where you can see the board covered by a metal shield. Note the indendation in the shield, which I think is intended to contact the processor to provide some heat sinking.

Figure 5 shows the main board, with the Marvell Orion 88E5182 storage processor. Note that it doesn't have a thermal pad to help thermal transfer to the indentation in the metal shield. Other components, which I suspect are shared with the CA are 64 MB of RAM (there is another Samsung K4H561638 32 MB chip on the other side of the board), 256 KB of flash and a Marvell 88E1118 gigabit Ethernet interface chip.

Like the CA, the CABE runs a modified version of FreeNAS and the drives are formatted with the UFS filesystem.
Power consumption is relatively low at 22W active and 14 W when drives are spun down. The single variable speed fan runs at very low speed, making the CABE virtually silent.
