Synology SNV5420-400G - Enterprise Series M.2 NVMe SSD (2280) 400GB

It works well, with high speed and easy installation, but it is overpriced. The problem is that Synology doesn't allow you to use NVMe drives that are not their brand.

read/write speed better

Seems to be working well. Easily installed and setup went smoothly. Now using as Volume 2 - SHR-1 and running VM with good response.

Synology’s Own Apps Don’t Work With DSM 7’s “modern” security selected. One of the reasons I went with Synology was their supposedly superior software. Surveillance station's functionality was severely hampered with the recent update to DSM 7.2.2 (removed h.265 codec support). DS Video has not been updated in two years and will not work if the NAS security is set to modern. DS video has other interface and CODEC issues, but it is pathetic that Synology hasn’t even updated the ciphers used in its software so that “modern” security cannot be used on Synology’s NAS. Now Synology is deleting applications and core functionality (h.265 codec support) for "performance." Never buying another Synology. The whole point of paying a premium for Synology is their software, not their years old sub-par hardware. Synology removing h.265 support over a ~$1 per device license fee is unacceptable. Turning to Synology photos, despite 30,000+ images, the AI only recognized the subjects in less than 500 photos, and then much of the recognition was wrong. It did much better with faces, but leaves much room for improvement.

Nice dirty picture of the back side! The photo guy phoning it in :)

"I'm totally undecided about the Synology DiskStation DS923+ 4-Bay NAS Enclosure Server. While it’s packed with features like the AMD Ryzen R1600 Dual-Core processor and 8GB of DDR4 RAM, I don’t feel it’s a great backup option for your average Joe. If you’re someone with a lot of technical experience, the additional bells and whistles might be appealing, but for someone like me, who isn’t as tech-savvy, it feels overwhelming. I also dislike that they charge extra for automatic photo updates—it feels like a feature that should be included. I’ve heard it’s possible to create a reverse DNS at no cost, but I’m completely lost on how to do that. Overall, this might be a fantastic product for advanced users, but for beginners, the learning curve is steep, and the added costs for some features are disappointing."

It's just an NVMe device. And the problem with Synology is they FORCE you to buy their NVMe and just don't allow any other brand. Ridiculous restriction.

The only documentation provided is a quick start guide with line drawings of plugging it in and turning it on. You're on your own from there, and the links they provide supposedly for further instructions do not work. EXTREMELY frustrating experience. Once I finally got it to communicate with the computer, I began having issues with backups stopping after 5 minutes, signing me out and saying my credentials are invalid.... even though I was just signed in! I have talked with several different Synology techs, and though they are all very polite, it has now been 5 weeks, and they have not been able to identify the problem. The NAS still has yet to make a successful backup, and the tech response has slowed from a few hours to several days. Currently it seems they are ghosting me, as it has been 4 days since my last communication. I think I must return this and find something else not made by Synology.
