The LaCie Two Big, bundled with a host adapter, is an economical hardware RAID that performs solidly. LaCie offers its Two Big packaged with either a PCI-X or a PCIe SATA host adapter. This is a good thing, since the Two Big did not mount with any of the other PCI-X host adapters we had on hand. A LaCie spokesperson said that its host adapters were specifically configured to work with the Two Big and LaCie’s larger S2S SATA RAIDs.
The bundled card has four open ports, only one of which the Two Big unit takes up. In our speed tests, the Two Big delivered average read speeds of 95 MBps and write speeds of 143 MBps when formatted as RAID 0 (striping).
The Two Big drive sports a hardware RAID chip controlled via a small dial on the back of the unit. With the turn of a screwdriver, you can choose between RAID 0 (or as LaCie calls it, Fast), RAID 1 (Safe), concatenate (Big), or JBOD (Just a Bunch of Disks). In our testing, when we changed RAID schemes, particularly from RAID 1 to RAID 0, the Two Big had occasional hiccups, where the Mac didn’t recognize the full capacity—as though one drive was offline. Powering the unit off and on seemed to alleviate the problem.
The front of the Two Big comes off easily to allow access to the swappable drives. LaCie sells bundles with drive spares—for expansion or as a backup.
The Two Big enclosure itself runs slightly loud and can get very hot to the touch.

Macworld’s buying advice
The LaCie Two Big, which comes bundled with a host adapter, is economical and provides solid performance. If you’re looking for a hot-swappable option with an attractive design, this may be the SATA drive for you. However, the included PCI-X card doesn’t work well with other SATA drives.
