SF3 Series - AJA PAK Media Pro Card Reader
Professional Thunderbolt Dual-Slot Reader for High-Speed AJA PAK Media Ingest
for Mac and Windows
Supports AJA PAK Media Cards at Full Speed
Superior Dual-sot Ingest Performance
When your multicam live event production, documentary, news or sports programming is captured to AJA Video System’s Ki Pro Ultra 12G 12G-SDI4K/UHD/HD recorder and player, your footage is recorded on ultra-reliable AJA PAK Media SSD cards. With the recorder’s ability to support four channels of simultaneous 1080p at 60 fps recording — or a 4K at 60 fps recording in single-channel mode — those cards fill up fast. The need for a tool that accelerates offloading media files from multiple cards is greater than ever, too. Sonnet SF3™ Series - AJA PAK Media Pro Card Reader is the perfect tool for the job.
Ingest Simultaneously from Two Cards
Dual Card Slots, Double Productivity
Certified by AJA, this Sonnet media card reader ingests media files from PAK Media memory cards at the fastest speeds the cards will support to any computer with Thunderbolt ports. And, for even greater efficiency, it can ingest files simultaneously from two cards at high speed — up to 1030 MB/s — to cut your ingest times in half.
Key Features
Superior Ingest Performance
Ingests footage from all AJA PAK media cards at maximum supported speeds.
Cuts Ingest Times In Half
Dual card slots enable simultaneous ingest of files from two cards for greater efficiency, up to 1030 MB/s aggregate.
Maximum Thunderbolt Performance
Pro media card reader provides four lanes of PCIe bandwidth for maximum performance.
Compact, Rugged, Stackable
Small and rugged aluminum enclosure for reliable operation; design enables multiple SF3 Series card readers to occupy same footprint.
Rackable
Threaded mount points enable secure attachment of two readers side-by-side on a rack tray in just 1U of rackspace.
Connect Additional SF3 Series Pro Card Readers
One port connects to computer; second port supports daisy chaining additional card readers.
Computer Compatibility
Compatible with Mac and Windows. See Tech Specs for details.
Ingest Six Cards Simultaneously
Daisy Chain Power
Because Sonnet’s PAK media card reader features a dual-port, high-bandwidth Thunderbolt interface, you can daisy chain up to six of them together to a single port on your computer. Connecting three readers to your computer enables you to ingest six cards simultaneously at full speed to complete the process — without swapping cards — in about one sixth the time required using a single-slot reader!
Rack It Up
Ready for Racking
Sonnet’s SF3 Series Professional Media Card Readers include threaded mount points that enable you to securely attach two readers side-by-side on a rack tray in just 1U of rack space.
Compact, Rugged, Stackable
The PAK Media Card Reader for Digital Imaging Technicians
For DITs working multi-camera shoots or in a small space, equipment size and design features matter. Sonnet’s PAK media card reader measures just 5.8 inches wide by 6.1 inches deep by 1.4 inches tall, making it suitable for use in any workspace and workflow.
Sonnet SF3 Series Pro Card Readers
Designed to be Stacked and Daisy Chained
SF3 Series Professional Media Card Readers feature rugged aluminum enclosures designed to be stacked and daisy chained, enabling multiple AJA PAK Media, CFast 2.0, CFexpress, RED MINI-MAG, and SxS PRO X readers to occupy the same footprint, while connecting to your computer through a single cable. You can take advantage of Thunderbolt’s up to 2800 MB/s of PCIe 3.0 x4 bandwidth to ingest four, six, or more cards simultaneously!
Thunderbolt Technology
Fastest External Interface Available
Sonnet Thunderbolt products feature a high-speed Thunderbolt interface that delivers PCIe bandwidth needed to support data transfers at full speed.
Connect Additional Thunderbolt Devices
One port is reserved for connecting to your computer; the second port enables connection of additional Thunderbolt peripheral devices in a daisy chain.
10 Gbps USB 3.2 Gen 2 Support
10 Gbps USB 3.2 Gen 2 support allows you to connect a USB device to the second Thunderbolt port using the proper cable or adapter.
Provides 15W of Power
For peripherals requiring extra power, 15 watts is provided to bus-powered devices through the secondary Thunderbolt port.
Supports Connecting Up to One 8K Display
Maximize the utilization of one computer Thunderbolt port, connecting the largest display supported by your computer.
Secure Connections for High Performance
Thunderbolt Cable and ThunderLok Included
Sonnet includes a Thunderbolt cable that supports Thunderbolt’s maximum bandwidth and is fully compatible with Thunderbolt 5, 4, and 3 computers. Sonnet also provides ThunderLok, a Thunderbolt connector cable lock, that prevents accidental cable disconnections.
ThunderLok Advantage
Many Sonnet Thunderbolt products featuring Thunderbolt ports come equipped with threaded mounting holes to securely attach a Sonnet ThunderLok connector lock, preventing Thunderbolt cables from accidentally disconnecting.
Built for the Fast Lane
Designed for the Fastest Connection to Thunderbolt Computers
SF3 Series Professional Media Card Readers are purposely designed with a Thunderbolt 3 controller and its four lanes of PCIe (not available in a Thunderbolt 4 peripheral) to achieve maximum simultaneous ingest speeds. Watch this video to learn more about the performance benefits.
