Pure Performance to Go

Fusion D500P Connected to MacBook ProWhen file transfer speeds in the field can make or break a project, call in the pro—Tempo™ SATA Pro ExpressCard/34. This Sonnet exclusive two-port eSATA adapter delivers the highest available throughput performance from a SATA host controller for notebook computers—40% faster than standard SATA controller cards—and is ideal tool for video capture and editing in the field, studio, or office. Tempo SATA Pro ExpressCard/34's exceptional sustained data throughput capability of up to 200 MB/sec empowers it to support more simultaneous video streams during playback, and enables faster file transfers for content of any kind.

Fusion F2 with MacBook ProBased on Sonnet's acclaimed Tempo SATA E4P SATA host controller for desktop computers, Tempo SATA Pro ExpressCard/34 delivers significant gains in read and write data transfer speeds over earlier-generation eSATA ExpressCard adapters, with remarkably higher throughput than FireWire® and USB 2.0 adapters, when used in combination with storage systems featuring two or more drives. Tempo SATA Pro ExpressCard/34 offers great storage expandability—its support for high-performance multi-drive storage systems with port multipliers or hardware RAID controllers enable it to handle up to ten hard drives (1)(2) at the same time! Port multipliers and hardware RAID controllers manage the data flow of up to five drives in one enclosure, transferring files between your computer and drives through a single locking cable. Connect two storage systems, using today's highest-capacity drives, and you can access an astounding 20 Terabytes of storage!

Tempo SATA Pro ExpressCard/34 controller plugs directly into a MacBook Pro with an ExpressCard/34 slot or Windows notebook with an ExpressCard slot, and is an essential tool for the professional creative person on the go.

Technical Notes

  1. Western Digital manufactures Desktop edition (WD Caviar, Caviar SE, Caviar SE16, and Raptor X) hard drives and Enterprise (RAID) Edition (WD RE, RE2, and Raptor) hard drives. Each type of hard drive is designed to work specifically in either a desktop computer environment, or connected to a RAID controller (hardware or software-based). If you intend to configure Western Digital drives in a RAID set, Sonnet and WD recommend using only their Enterprise edition hard drives. For more information, see this Western Digital FAQ.
  2. 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 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.

  3. Tempo SATA Pro 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 in these operating systems, such as a SATA controller.
  4. When upgrading to OS X 10.10 (Yosemite) you must reinstall your product's Sonnet driver software.

AMUG Reviews
"…provides the highest eSATA ExpressCard/34 performance that AMUG has recorded.


Sonnet Tempo SATA Pro ExpressCard/34
The Sonnet Tempo SATA Pro is a very strong performer in terms of throughput. Speeds shown here increase by about 10% with 32MB chunks instead of 1MB chunks. These are excellent results for the MacBook Pro, indeed unprecedented prior to Dec 2008…

When choosing eSATA on the MacBook Pro for performance reasons, the higher price of the Tempo SATA Pro ExpressCard/34 is easily justified for big jobs, such as Photoshop. And for backups of large data sets, the higher sustained throughput will cut the time down considerably."

Excellent Pro Card
There is a big difference in speed with the Pro model versus the standard model, noticeably in speed. The speed tests I ran on a set of 2-drive RAID-0 externals were faster on my Macbook Pro i7 than on my Mac Pro! My specific application was downloading RED Drives onto a pair of hard drives, and the card reader cut my transfer times in half; 100 GB transfered in under a half-hour. When the drives were clean, AJA reported over 150 MB/s read and write. (that's capital MB)…"

A Definite Upgrade
I use this for video editing with Final Cut Pro on my MacBook Pro. I have it connected to a GRAID 1TB Quad Interface and have also used it simultaneously with my G-DRIVE 500GB Quad Interface. It's noticeably faster than Firewire 800. I used to use that all the time for my primary editing interface with external drives. Renders are faster, not mind-blowing, but you can see and feel the difference. Scrubbing thru the timeline is also snappier especially when working with standard definition video. Dropped frames aren't as frequent as video plays back smooth the majority of the time but part of that might be due to my computer and what I have running. I got this item because I felt I needed to maximize my editing solution once I started working more with HD material and felt Firewire 800 wouldn't suffice. On my MacBook Pro I felt this was the most affordable solution all around from pre-production, production, to post and it's been working great."

Tempo SATA II Pro ExpressCard/34 2-Port
As far as I know, there is no other eSATA card that outperforms this product that currently exists in the market. I've done some research on this and tried out different brands, but none really suited my needs like this one…"
