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. ### ⭐⭐⭐⭐⭐ Hope this lasts long like the old one *by S***R on July 20, 2025* The raid finally died on my old terrastation I ran out of spare drives. I bought a couple of spares for this one. The old on lasted around 15 years 10 of those years has at a business with 50 users till we upgraded to a larger server. ### ⭐⭐⭐⭐⭐ Great price and best quality and overall design, reliable *by C***N on April 24, 2021* Quality NAS, fast and well designed software.The 4 bays and raid 5 is the best value, this system works so reliable and also future proves with 2.5GE port plus 1GE port aggregation.I have it for a few months and have not seen a small hick up.Highly recommended! ## Frequently Bought Together - BUFFALO TeraStation 3420DN 4-Bay SMB 16TB (4x4TB) Desktop NAS w/Hard Drives Included Network Attached Storage - APC UPS Battery Backup and Surge Protector, 600VA/330 Watts Backup Battery Power Supply, BE600M1 Back-UPS with USB Charger Port - APC UPS 1500VA UPS Battery Backup and Surge Protector, BX1500M Backup Battery Power Supply, AVR, Dataline Protection --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.au/products/247753901-terastation-3420dn-fully-populated](https://www.desertcart.com.au/products/247753901-terastation-3420dn-fully-populated) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-05-03*
