Key to Fast External Storage

Fusion D500P Connected to MacBook ProSonnet's Tempo™ SATA ExpressCard/34 provides eSATA connectivity for the mobile Mac® or Windows user who needs access to fast external data storage. When speed matters most, eSATA is the interface of choice—it delivers the best performance from storage systems with multiple interfaces (FireWire, USB, eSATA(1)). This Sonnet host controller has two external, 3Gb/s, SATA II ports, and offers scalability through its support for drive enclosures with port multipliers or hardware RAID controllers. Imagine connecting up to 10 drives(1) to your notebook—Tempo SATA ExpressCard/34 makes it possible.

Tempo SATA ExpressCard/34 can sustain read and write speeds to a single SATA drive of up to 125 Mb/sec, about four times as fast as USB 2.0. With two Fusion D500P 5-drive desktop storage systems connected, you can access up to 20TB of files. Tempo SATA ExpressCard/34 even supports Mac OS® X, Windows 7 (Professional or Ultimate), Windows Vista® (Enterprise or Ultimate), and Windows XP Pro RAID features, so you can configure your storage the way you want it.

The Tempo SATA ExpressCard/34 controller plugs directly into a MacBook® Pro (with ExpressCard/34 slot) or Windows notebook with an ExpressCard slot, and delivers enhanced data transfer speeds for the creative person on the go. Whether you capture and edit video content in the field, the studio, or home, or simply need access to terabytes of files, Tempo SATA ExpressCard/34 sets the bar high for mobile storage product performance.

Technical Notes

  1. Sonnet Tempo cards are compatible with most external SATA storage. However, external hard drives with USB 2.0/eSATA dual interface based on the Oxford Semiconductor OXU931DS storage controller chip may not be compatible with Mac OS X when connected via SATA. Known issues are kernel panics occurring when the drive is connected, or the drive not being recognized by the operating system.

  2. Tempo SATA ExpressCard/34 not supported under Windows 7 or Windows Vista when running on unibody MacBook Pro computers. The problem is caused by the MacBook Pro's BIOS emulation, which doesn't allocate enough resources to support certain kinds of Expresscard/34 devices, such as a SATA controller, in these operating systems.
  3. Compatible with only Echo ExpressCard Thunderbolt Adapter (part no. ECHO-E34). Not compatible with Echo ExpressCard Pro Thunderbolt Adapter (part no. ECHOPRO-E34).
  4. When upgrading to OS X 10.10 (Yosemite) you must reinstall your product's Sonnet driver software.

"…Want to take advantage of eSATA and RAID on your MacBook Pro? Sonnet's Tempo SATA ExpressCard/34 is an easy way to make it happen.

Buzzillions Finalist 2011 So Happy to Have It
With limited hard drive space on my laptop now I can bring along a portable esata hard drive and start editing right on the shoot then easily continue when I get back to the studio and I want to work from my mac pro instead."
Buzzillions Finalist 2011

Excellent - Low Cost Card!
Low cost card to improve file writing and transfer.

A great improvement - The Pro Card must be even better but this one has worked great for us to use an external drive as a Photoshop scratch disc and to work directly from the external on large projects.

Works as advertised."

Buzzillions Finalist 2011

Did the Trick!
I have several portable drives with eSATA ports, but no port on my MacBook Pro. I was getting many freezes in FCP when drives were daisy-chained. This solved the problem. It gives two eSATA ports with amazing throughput at a great price."
