Review: reasonable price and performance lasts 2 years - I have a dedicated 24/7 NAS setup using a Synology DS 723+ which I upgraded to 32GB RAM and 2 TB of M2 Cache and use in RAID 1. I first setup the NAS in late 2023 with 2 of these 8TB N300 and around October 2025 I received a warning that one of the hard drives failed. I therefore bought a new one which had slightly diff specs since it was newer (512mb vs 256mb cache). It worked seamlessly (plug and play) and the RAID was rebuilt. I have the NAS in a dedicated area not is not in close proximity so noise was not a concern for me. However when up close the drives do make a little more noise than other hard drives. Not thunderous but not silent either. In summary, the drives work well. I had one failure just after 2 years (which is reasonable in my view) and replacement was seamless for rebuilding the RAID.
Review: Speeds up 280 mbs are legit - So far so great. Ran for 9 hours and the drive only got warm. Using oracle 3.5 enclosure

### ⭐⭐⭐⭐⭐ Unmatched NAS performance and reliability — highly recommended
*by A***R on March 23, 2026*

Absolutely outstanding drives. Truly unmatched in performance and reliability. I bought 6 of them and couldn’t be happier. Perfect for NAS use — stable, fast, and quiet for their class. It’s a pity there’s a current shortage, I’m waiting for availability to buy 2 more. Highly recommend.
