ThunderBay 4 mini
8.0TB Professional Grade 4-Drive HDD Thunderbolt 2 Solution For Mac and Windows PC
Featuring SoftRAID Lite XT
The Perfect Combination of Speed, Size, and Convenience for Permanent Access to Your Data
Big RAID System Performance in a Compact Design
The ThunderBay 4 mini is perfect for repurposing or maximizing 2.5-inch drives for a compact data storage solution. It’s big on performance and flexibility, yet ThunderBay 4 mini is about the length of a pencil and can weigh as little as 3.1 pounds with drives.
The rugged heat-dissipating aluminum enclosure features two Thunderbolt 2 (Thunderbolt 10Gb/s backward compatible) ports for up to 1346MB/s 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 drive bays, you can mix or match different brand and capacity 2.5-inch SSDs and HDDs. Use mixed drives independently or combine drives as a RAID with the included SoftRAID setup and management software. You can order as an empty enclosure and populate with your own drives, or choose a variety of pre-configured capacity solutions to achieve your desired balance of storage, performance, and data redundancy.
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.
- Four 2.5-inch drive bays
- Up to 1346 MB/s with (2) Thunderbolt 2 ports (Thunderbolt 2/Thunderbolt backward compatible)
- Daisy-chain up to five additional Thunderbolt devices
- Easy RAID setup with included SoftRAID Lite XT software
- Thunderbolt certified for Mac and Windows
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.
- Up to 86% faster versus AppleRAID
- Create advanced RAID 0, 1, 4, 5, 1+0 (10) volumes for higher performance and/or redundancy.
- 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
