Buffalo has done a solid job with the TeraStation 6400 both in hardware choice, which happens to be the same configuration being used by ASUSTOR with our recently reviewed Lockerstor platform and Synology with its DS1618+ and DS2419+, and the steady updates to features consumers want. Most notably in my testing was the addition of snapshots, which has become a must-have for my own data.
Build quality is quite good with your standard 1U metal enclosure, included rails for mounting the NAS simplifies the installation process and information center along the top of the drive trays offers all the needed info with LEDs.
The performance was on par with expectations, and having tested this unit with 5Gbe in our new test system, there were a few occasions where we did reach the limit of the interface. That said, the sequential performance was quite good, especially in read operations, while write performance at its lowest was 285 MB/s in RAID and 373 MB/s in RAID 0. Workload testing again showed this hardware loves Database workloads, reaching 20K IOPS in RAID 0, 11K IOPS in RAID 5, and 8K IOPS in RAID 6.
Pricing of the TeraStation 6400RN is coming in hot with an MSRP of $2319.99 for the 16TB model and $2899 for the 32TB model. That said, these units do feature a three-year warranty and are TAA compliant, making them a viable option for government agencies while homelabbers and consumers may want to look elsewhere for more budget-friendly solutions.

The Bottom Line
The TeraStation 6400 is a solid platform, turnkey for rapid deployment and better than ever with snapshot and remote management features.
