At the 2012 Consumer Electronics Show in January, LaCie announced a new product for Thunderbolt users. The eSATA Hub Thunderbolt™ Series is a $199 Thunderbolt pass-through that allows you to connect 2 eSATA drives to your Mac via the speedy Thunderbolt port. By Daisy chaining six of the devices, you could add 12 eSATA drives to your Mac setup.
Today, those devices are now available.
eSATA speeds are up to 3Gb/s or equivalent to SATA II, so you will not be making full use of the Thunderbolt bus speed. However, you will still be much faster than either USB2 (480Mbps) or Firewire 800 (800Mbps). Apple’s Thunderbolt cables are sold separately at $50 a pop.
eSATA docking stations start at around $30, so if you have some eSATA or SATA drives laying around and want to get them on Thunderbolt, this might be a good—though slightly expensive–solution.
Seagate makes a $99 Thunderbolt to SATA drive adapter, but it is having trouble keeping stock (and it lacks a Thunderbolt pass-through) and reviewers note erratic results.
The full specs and press release follows:

We first profiled the Western Digital MyBook Thunderbolt Duo at CES in January and noted the extraordinary speed of the drives, especially when daisy chained (above find 780MB/s read, 600+MB/s write). Today, Macrumors notes that Western Digital is making the drives available for $599 (4TB) and $699 (6TB). While those prices are steep, they fall in line with new Thunderbolt parts across the line.
We’ve reviewed the much slower Firewire/USB Western Digital Studio 6TB drives and came away impressed. Those retail for around $430 currently ($270 less than the Thunderbolt version) but use energy efficient (read: slower) internal drives and slower Firewire 800 connectivity options.
Notably B&H Photo and Video is selling the Western Digital MyBook Thunderbolt Duo already with $50 discounts (6TB – $649, 4TB- $549) and tax only in New York but without solid shipping dates. expand full story
