[2.15 lb] This item which I received quickly has performed just as I expected it would. I have zero issues.

[ 3.5" HDD ] I bought this unit after receiving help from an informative sales rep at B&H. His recommendation for my buying the Buffalo 8T (4 X 2T) TerraStation was based on my needs (I formerly had a WD 8T MyCloudHome NAS which is no longer supported) and on Buffalo's excellent help line which I can attest was outstanding in helping me. I have 4 Mac computers (3 Ventura and 1 Monterrey OS) on the NAS through a QNAP 2104 switch (also from B&H) and each one backs up correctly through Time Machine with my TerraStation using Raid 5 (Only 6T available with 1 drive designated as the emergency reserve). The unit is well built with a solid metal chassis. The unit runs cool. The 2.5 gig signal works correctly and firmware is updated without any difficulty. Setup was done through NasNavigator 2 software. All connections are through Cat 6 cables. I am very pleased with the results.

[3 TB] I recently got the Buffalo TeraStation Essentials 8TB 4-Bay NAS Array for our small business, and wow, it's made a big difference! With 8TB spread over four 2TB drives, we've got loads of space for all our important files. Setting it up was super easy, which was a relief, and using it was straightforward, too. It's quick and reliable when we access our data, which helps everything run smoother day-to-day. Plus, it feels sturdy and well-made, so I'm not worried about it breaking down on us. Honestly, adding the TeraStation to our setup has been a great move for keeping our data organized and easy to get to.

[3 TB] Have had this for a few weeks now and I've had no issues with it. I'm using it for keeping all my photos and videos in one place and not spread out over several devices. I also want to get rid of remove cloud subscriptions and have everything in one place. I'll eventually add the other hard drives as the need arises. I'm very happy with the purchase. It's my first NAS and things were easy to set up.

[ 3.5" HDD ] Set up as a 4TB available RAID 1 and it has excellent data transfer speeds as well as data security. As always, B&H pricing was tops!

[2.15 lb] The drive works great but I needed to speak with two people at Buffalo to get it to rebuild.� Regardless, Buffalo will provide phone support even if the product is out of warranty.� You can't beat that.

[3 TB] Exactly as described. A good price for a fully functional Windows IoT storage server. Quiet and powerful.

[3 TB] How excited can you get about a hard drive -- unless your NAS Raid array loses a drive. After calling Buffalo (manufacturer of the NAS unit), they gave me the specs for the replacement. I was very happy to see B&H among the online retailers that handle these, and extremely happy, but not surprised, that B&H had a great price. Some vendors matched B&H but none beat B&H. The NAS unit is back up and running great.

[3 TB] Bought as a shared backup solution after Drobos died and that company is going belly-up, with no support or products. TeraStation was easy to connect up and set up shares to multiple PCs. Robust with plenty of capacity.

[ 3.5" HDD ] These TeraStation raid arrays work well. Buffalo support is excellent. Email notifications are easy to setup.
