Seagate must be pleased with the acceptance of its four-drive BlackArmor NAS 440, because they're back with a two-drive version. The NAS 220 supports most of the features of its higher-capacity sibling, which we've previously reviewed. So I'll just focus on what's different, review its new hardware platform and run through the performance test results.
The 220 is housed in a metal case with a plastic front panel. It's a no-frills design meant to convey a no-nonsense approach designed to appeal to its target small-biz buyer. It's a bit taller and wider than the Synology dual-drive NASes, but not quite as big as Cisco's Linksys Media Hub.
Figure 1 shows the front and rear panels. The front has status and drive activity indicators, the Power button but no USB ports, while the rear has two USB 2.0 ports and a Gigabit Ethernet port that supports jumbo frames up to 9K. Unfortunately, it has no eSATA port to help support faster backups to attached drives.

The single fan ran quietly and drive noise was low enough to make the unit barely audible in a quiet room. I didn't hear the fan speed ramp up during the load of our performance testing. Power draw measured 22 W active and 7 W with drives spun down via the HDD Standby feature. You can't set the spindown time and there is no programmable shutdown / startup feature.
The 220's metal case has a plastic front panel that doesn't easily remove to provide access to the two 3.5" SATA drives. For that, you need to remove three screws and slide off the metal cover to reveal the two toaster-style top-inserted drives (Figure 2). Our 2 TB review model came with two ST31000528AS Barracuda 7200.12 1 TB drives installed, which are EXT3 formatted.

Figure 3 is a shot of the 220's board, which is mounted below the drive cage. The board is not the same as the BA NAS 440 and uses a slower version of the Marvell "Kirkwood" SoC line, an 800 MHz 88F6192 vs. the BA 440's 1.2 GHz 88F6281.

Other key components are a Marvell 88E1116R Gigabit Ethernet, 128 MB of soldered-on RAM, 32 MB of flash and a Genesys GL850A 4 port USB 2.0 Hub. Note the unloaded position for a second RAM chip.
