Review: Best Bang For Your Buck for Small Business - Firstly, you get so much value with this item. I ordered the 4 drive 8TB (4X2TB drives) as a file server for my small business. The machine is made in Japan which gives me confidence in its quality, and although this NAS is small, it is hefty, solid and well built. Out of the box you don't get much by way of what to do with it. There is only a quick setup on how to plug it in, but nothing about what to do with it. Visit this site to get started. buffalotech.com/products/terastation-3020-series-desktop I used to help manage a large network years ago, and we installed Buffalo terrastations so I had some experience with them, but really, this unit is super easy to configure and is packed full of value added services such as links to popular cloud storage services, virus protection from TrendMicro, notifications, and several other enterprise level options. The unit comes preconfigured RAID 5 with options for RAID 5 + Hot Swap, and RAID 6 which I chose during setup. I'm a bit rusty with my tech knowledge, and this NAS was a breeze to setup. I highly recommend this product for small businesses and personal file storage use. I would not recommend it for enterprise use as it's missing some redundant features to prevent downtime. Overall, Ding Dong.

### ⭐⭐⭐⭐⭐ Solid SMB Hardware Backed by Incredible Support
*by N***. on April 9, 2026*

Our team has been using the Buffalo TeraStation 3420DN for our IT system, and it is a workhorse. The 16TB capacity (shipped with drives included) made the initial deployment seamless, and the 2.5GbE port provides a noticeable boost in file transfer speeds for our office. What really sets Buffalo apart, though, is the support. I’ve been working with them for 5 years now, and Eric from tech support is hands-down the best. Every time I’ve called over the years, he has been incredibly helpful and knowledgeable. Knowing that level of support is available makes this an easy choice for any SMB looking for dependable storage.
