I deployed two of these. Perfect by design. It's a 24-lane PCI switch from IDT/Renasas, part number 89HPES24T6G2, plus a Marvel 2-port SATA controller on the back. It is an 8-lane physicl and logical connection at up to PCIe 2.0 speeds. Each M.2 slot supports any M-key SSD as long as they are both SATA or both NVMe. In NVMe mode, that's a 4-lane PCIe slot. In total, it uses 16 of the 24 lanes, meaning the PCIe switch is never overloaded. Linux automatically supports this switch, but the version you run sets the stage. When this card was serving up two NVMe drives, I could see them, but as soon as I wrote to either of them, it went into I/O aborts, timeouts, and hung until powered off. Two of these cards, 4 total NVMe drives. Not a bad device issue. I'm using OVM Server 3.4.6.2. Pulling the NVMe drives loose, and plugging them into single-drive risers, they work fine, so it's specifically related to PCIe switching. There is an ASM card on the market that does the same thing, and maybe it works better. I have not tried it. There is a high-point raid card that some people have had success with. Doing research, it seems there is still code work going on in Linux and FreeBSD for these kinds of errors. perhaps, some newer release would make this work, but that does not help for an enterprise Linux distribution today. Synology has specific hardware and specific OS builds to solve this problem, and some of it may be throttling the performance of each lane somewhat in the kernel, handling TRIM commands, handling reset commands, etc. Maybe in OVM 4 and RHEL 8 we'll see something stable, but today, I just can't use these in a standalone Linux system. That said, this is my limitation. The hardware is great. The heat sink assembly is well thought out. The screw kit is perfect, and it comes with both low and full profile backplates. It looks clean, well designed, and just overall a great piece of hardware. Also, the price is excellent for what it is. It's very competitive. If you have a supported Synology storage array, or are on bleeding edge Linux, or are using SATA M-Key drives, then this could be a great option for you.

I purchased this to speed up my DS1517+. I installed dual Kingston 240GB NVMe and nada. I accept fault for not reading carefully enough, but even the tech support rep advised this is a pretty common complaint... If you are intending to use this to add NVMe SSD Caching to the DS1517+ like I did, sit tight. While I knew the previous card would allow only SATA speeds it was extremely refreshing to see that the M2D18 can take advantage of the much faster NVMe protocol. So like a dolt I buy the card and 2 NVMe drives to get things going. Only to find out that this card does not enable NVMe protocol on the DS1517+,even though it is "compatible". If you have the same situation, you can only use SATA since the DS doesn't recognize the NVMe. I really love Synology products and while these add ons are definitely overpriced, they usually work. Personally I think Synology should clarify this fact better. Consumer is led to believe that they are adding NVMe protocol when it is absolutely not the case when using DS1517+ Again... hindsight being what it is, yeah I accept that ultimately they do kind of let you know you probably won't have NVMe , but no....they fumbled by listing compatibility here.... It definitely should have a giant asterisk!

Support for m.2 should be build on MB, and because its not you have to chose between caching or 10gig network, which sucks big time. Adding this functionality to synology increases cost drastically and reduces your choices of functionality. Also you limited by cache to how much ram you have, so you cannot add whatever size you want. Not to happy with this but what other choices do I have? Wish I could have 10 gig network and this cache at the same time.

Admittedly, this was my first time ever dealing with a NVMe PCI Card. The instructions were not really written for a noob. However, with some help from Youtube and a friend, I was able to get it installed going. The addl heat sinks have this adhesive that does not stick very well. Once I got it in though, WOW... big difference in performance. totally worth it.

If you are going to splurge on a large scale Synology, this and a pair of high performance M.2 SSDs are a no brainer. Easy to install and configure, they add a massive bump in speed, especially if you are doing multiple streaming activities at the same time. I have one in my 8 bay Synology NAS and its made a huge impact on my media streaming, both in house and offsite via PLEX.

Fit right in. Does what it is intended. I put in two 512GB cards in and can see a vast improvement of speed.

This has had a very positive impact on the performance of my Synology, which is setup with SHR2 5 drives using 2 nVME as read/write cache for the BTRFS volume. Is it worth the money, well i'd say it entirely depends on your usage if you have a small office with thousands of files or photos then yeah maybe, overtime as they get cached you'll see a noticeable improvement, however if you are just storing large media then you won't likely see any difference except when copying/uploading to the NAS unit.
