ThunderBay 4 checks all the functional boxes to make you a more efficient content creator: fast data access, enormous storage capacity, centralized (and hassle-free!) file location, and it works with Macs (Intel-based plus the latest Apple Silicon M1/M2/M3/M4 machines) and Windows PCs. What makes ThunderBay 4 the best 4 bay storage solution available is its time-proven reputation of providing peace of mind your data will be safely protected today and tomorrow.

We Never Rest. Our Good is Better. Our Better is Best
What's most important to you in a storage solution is likely entirely different than another content creator. That why we don't rest on our laurels and continue to make sure ThunderBay 4 doesn't make you compromise. Merge four drives in a RAID 0 for huge performance and capacity gains over using a single external drive. Combine the capacity of three drives and use the fourth for RAID 5 data protection that keeps you working even if one of the drives fails. Or choose a DIY kit and add your own SATA SSDs for ultimate speed.
