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.

### ⭐⭐⭐⭐⭐ A very satisfied return customer
*by R***Y on February 28, 2023*

A worthwile upgrade over the TS3000 series of which I own 4. NAS response and throughput seems to be faster, but they did reduce available USB ports by 2 (compared to the TS3000). I imagine this might be an issue for anyone needing more than 2 attached USB drives. It came loaded with 4 ironwolf disks which was a pleasant and much appreciated surprise! The UI is more modern looking yet still familiar. Build quality is what I would call industrial-grade with robust and nicely finished metal chassis and disk trays. Even though my TS3000 units have been working flawlessly for years, they apparently don't receive software updates any more, which motivated me to start upgrading. I just hope Buffalo keeps these TS3040 units in support for a long time to come.
