Buffalo TeraStation 3420RN 32TB 4-Bay 1U Rackmount NAS Server (4 x 8TB)

The Buffalo TS3420RN3204 is a four-bay network attached storage server that delivers 32TB of raw capacity through four pre-installed 8TB drives. Built around an Annapurna Labs Alpine AL-214 processor running at 1.4 GHz and supported by 1 GB of DDR3 memory, it handles everyday file sharing, backups, and light virtualization tasks in small offices or demanding home workspaces without slowing the team down.

The hot-swap design lets you replace a drive while the system stays online, keeping projects active and preventing downtime for colleagues or clients who need constant access. Flexible RAID options, including JBOD, 0, 1, 5, 6, and 10, make it easy to choose between maximum capacity and stronger redundancy depending on the data you store.

Dual multigigabit Ethernet ports support link aggregation for higher throughput or failover networking for extra resilience. Built-in B-Sync integration connects the NAS to cloud platforms such as Amazon S3, Dropbox, and OneDrive, so you can mirror critical folders off-site or give remote coworkers an easy way to pick up files.

An intuitive web interface works from any browser, desktop, or phone, allowing quick checks on drive health, user permissions, and scheduled backups even when you are away from the server room. The 1U rackmount chassis fits neatly into standard racks, a convenient choice for branch offices, retail back rooms, or tight home lab environments where every rack unit counts.

Buffalo backs the system with a three-year warranty that includes 24-hour hard drive replacement, giving owners the confidence to rely on this NAS for everyday business continuity and long-term archiving.
