ThunderBay 4 mini 16.0TB Professional Grade 4-Drive SSD Thunderbolt 3 Solution For Mac and Windows PC
Featuring SoftRAID XT
Big RAID System Performance in a Compact Design
The ThunderBay 4 mini SSD equipped solution is big on performance and flexibility yet sized about the length of a pencil. The rugged heat-dissipating aluminum enclosure features two Thunderbolt 3 (Thunderbolt 2/Thunderbolt backward compatible) ports for up to 1556MB/s real-world speeds, so you have more than enough bandwidth to handle personal and business backups — all the way up to today's highest resolution audio, photo, and video formats. If you are seeking big RAID performance that's small enough to fit on a desk, in a rack, or on a DIT cart, your wish is now a reality.
A New World of Drive Flexibility
With four SSD populated bays, you can use the drives independently or combine drives as a RAID with the included SoftRAID setup and management software. The ThunderBay 4 mini is also perfect for repurposing or maximizing bare 2.5-inch HDDs and SSDs you already own.
Expand production capabilities in industry-leading creative platforms like Final Cut X, Avid Pro Tools, Apple Pro Logic, and Adobe Lightroom, edit large images, manage massive photo and audio libraries, store drone videos, use it as a transport drive…whatever the day or project demands, the ThunderBay 4 mini is the perfect workflow solution.
Install or Swap in Minutes
Want to access another drive or expand your storage capacity? Simply open the front panel security lock to access the four individual bays. Drives mount to a tray that slides back in and automatically plugs into a drive connector so you can get back to work in minutes.
Store More, Go Faster
With the ability to daisy-chain you can add up to five additional ThunderBay 4 mini solutions to create massive storage capacities. Merge them with SoftRAID for even more flexibility, capacity, and capability. Or if speed is what you’re after, connect multiple ThunderBay 4 mini solutions to multiple Thunderbolt 3 ports on your Mac or PC to achieve exponential speed capabilities.
Includes SoftRAID: Easy and Complete Drive Management
Now you can quickly access and robustly protect your data with SoftRAID XT. SoftRAID easy setup makes it a breeze to create RAID volumes by helping you through the entire process. With multiple RAID options, you decide what you’re using your RAID volume for and how much space to allocate to it. It's that simple to create your preference of speed and/or redundancy for your data volume.
Enterprise-class monitoring for drive and RAID volume health with email notifications
Volume validation to ensure sectors can be read, parity is correct, and minimization of volume failure
Drive certification checks that your drives are safe to store data before use
Drive failure prediction with early warning helps protect you from sudden drive failure
