Great value, high performance NAS. 4 bay business NAS with integrated multigigabit port.

The TeraStation™ 3420 series is a high-performance, cost-effective 4-bay Network Attached Storage (NAS) solution, ideal for small businesses and demanding small office and home office (SOHO) users. With a powerful Annapurna Labs Alpine AL-214 1.4 GHz quad-core processor, it provides speedy transfer rates and stable operation during heavy-load work tasks. The robust central processing unit (CPU) and 1 GB of DDR3 RAM means it can run multiple services simultaneously. This allows businesses to focus on concurrent tasks with minimal performance degradation.

Rsynch Feature
Users can make backup copies from TeraStation to a rsync-compatible device from another manufacturer. This function also allows backups to be made from another manufacturer’s rsync-compatible NAS to the TeraStation NAS.

Active Directory
TeraStation functions as a client of an Active Directory domain, so that domain users and groups can be used. This means that they can be used in domain environments of companies with up to 10,000 users and groups.

Cloud-ready!
Buffalo’s TeraStation Series features B-Sync, which allows users to easily synchronize files between their TeraStation and 3rd party cloud services to make backups. The Buffalo NAS supports Amazon S3 Cloud Services, Dropbox, OneDrive and Azure.
