SATA

Mechanical hard drives will continue to be available — though decreasingly important — into the foreseeable future. New drives are cheaper and higher-capacity than increasingly popular solid state drives, and old drives pulled from computers are hard to throw away, even if they’re past their prime. Most people would seek out an external hard drive enclosure, which is ideal if you want to commit to repurposing one internal drive for an extended period of time. But what if you want to swap multiple internal hard drives in and out on an as-needed basis?

Sporting a substantially metal chassis with Thunderbolt 2 and USB 3.0 ports, OWC’s new Drive Dock ($245) is a premium solution for people who want high-speed, on-demand access to internal hard drives. The top has two SATA-compatible drive bays, each capable of holding 2.5″ laptop drives or 3.5″ desktop drives, while the bottom holds a power supply capable of safely powering both drives as plug-and-play volumes…

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:

While you might be familiar with iFixit from its in-depth teardown guides meant to provide the ultimate resource for DIYers, it also offers the necessary tools to get the job done. We told you a while back about its “iPhone oppression kit” allowing you to swap out Apple’s pentalobular screws with standard Phillips screws. Stemming from a discovery of two unused mounting points in its recent 21.5-inch and 27-inch iMac teardowns, iFixit is now providing a kit that provides all the tools necessary to install a second hard drive in your mid 2011 iMac.
