Either that, or worse: data-eating crap like many low-cost PCI-SATA host bridges (such as some of the sil3xxx chips). > really usable in Linux?

It is best to avoid SATA port multipliers like the plague because of that, since it is extremely difficult to shop for an external bay with a particular chipset... Look for a specific hardware product that has been in the market for at least two years, and with many happy *Linux* users (Windows drivers might be working around chip errata unknown to Linux libata). Sorry, I can't personally recommend any. Or get a SAS HBA, and a SAS-attached enclosure. Far more expensive, but at least you can be sure it will work very well (yes, it will take SATA disks as well as the more expensive (and better) SAS disks). -- "One disk to rule them all, One disk to find them.
