Very reliable and cost effective drives for my SYNOLOGY DS-224+ NAS
Two of these 16TB SYNOLOGY hard drives are in use in my SYNOLOGY DS-224+ 2-bay NAS, setup in a Synology Hybrid Raid 1 (SHR1) configuration spinning 24x7 providing 14+TB of storage, housing all my data and photos. Installation in the toolless SYNOLOGY NAS case is very simple. They’ve been at work for almost a year without any issues. I recently found the price reduced to a point made sense to lay in a spare 16TB for the “just in case” need. I am looking at possibly upgrading to a SYNOLOGY 4 bay model within the next year or so and will need 2 additional 16TB. While there is strong differences of opinion in forums as to the viability of using these drives or 3rd party drives from other major manufacturers in SYNOLOGY NAS devices, I chose to use these based on 2 points. First, the price point for the SYNOLOGY branded 16TB drives (reportedly manufactured by Toshiba) was comparable (within a few dollars) to the 3rd party offerings and secondly, according to SYNOLOGY’s support requirements, using non-approved options “could” impact warranty coverage. Even though some 3rd party drives were on the Approved Equipment List, I personally chose to stay fully with SYNOLOGY to avoid any and all warranty issues that might arise from 3rd party drive use. The access to the NAS using these drives is adequate for my needs. I have not experienced any what I would call abnormal transfer speeds. I’m sure it could be faster if everything was streamlined and optimized. The drives are barely noticeable sound-wise. Occasionally I will hear a slight noise from the NAS as the drives are being accessed but normally really quiet. Being a single user system, it does not run excessively hot, usually the NAS case is just warm to the touch. I suppose if there were many users and the drives were being constantly accessed, the temperatures might be higher. All in all, I have been pleased with the system, performance and maintainability of these SYNOLOGY 16TB drives.

Who doesn't need more storage?
I got this for my NAS. Had it for about a year now and I have not had a single issue. Instalation was super easy. It plugged in works great. Runs super quiet. Large storage capacity is always a bonus. Accesses data super fast for being a disk type hdd. Almost to a point that I need another. I use mine for a personal media library so it get used daily. Almost at a point that I need another. I would buy this again!

Synology's Own Drive: A Perfect Choice
I chose to expand the storage in my Synology DS115j NAS and found the company made its own hard drives at a competitive price. It has been in use over a year now without any problems at all while we do monthy backups of two desktops.

Quality HDDs for my SynologyNAS.
A good range of storage capacities, 12TB was perfect for my needs. Well packaged and arrived on time. Addresses the issue that Synology introduced with the compatibility requirement for HDD to be used by their NAS and current version of DSM. In my case I was not able to do a normal drive replacement, it would not work. Be sure to do a complete backup of your data and NAS configuration if you are replacing HDDs in your current NAS. HyperBackup worked perfectly for the backup and restore.

Quiet and easy to install in synology nas
I was looking to add storage capacity to my synology NAS. This drive gave my the extra capacity and was very easy to add to my NAS. It’s quiet and just as quick as my other RED drives I’ve used in the past. I’m hoping these have the lifespan and quality that my previous drives had, but so far I’ve only had this installed for a few months. No issues with them yet.

This is my first NAS system and I went with the recommendations (Synology harddrives for the Synology NAS) that I reviewed on the web. The Synology Nas system was easy to setup and everything seems to be working great. So far the harddrives and NAS system are working as expected.
