Synology10Gb Ethernet and M.2 Adapter card E10M20-T1, RJ-45; 1 port

Equipment 100%, easy to install.

I bought this and it didn't work in my particular Synology NAS model, so I thought hmm, let's try this in my Asus z490 Windows 10 PC. And I got very lucky.Here's a hint: with 2 cards, and 4 NVMe, I get 10,000MB/sSee the attached AS-SSD and CrystalDiskMark NVMe performance image.Without a driver, the 2 NVMe drive show up fine in Windows 10, but to get the Acquantia NIC chip to function you must use the following driver:Driver: Marvell Acquantia AQC107 driver (v2.1.21.0 in my case)Download: Go to Marvell, Support, Ethernet, Driver Download section and download the Win10 driver for part# AQC107Note: Marvell purchased Acquantia recentlyThe card has a PCIE 8-lane interface. The 10gbe NIC would use up 1 to 1.2 of those lanes, leaving 7 lanes or so for the 2 NVMe drives. I am not sure if they are using a PCIE switch to balance that out - which would be the most ideal way to do it. Either way, this is magic. With 2 of these E10M20-T1 cards, I finally have 2 10gbe NICs and 4 Samsung 970 Evo Plus NVMe sticks feeding the CPU via 16 PCIE Gen3.0 lanes (My Samsung 980 Pro NVMe runs off slow PCH lanes for my boot drive).Oh...I bet tis works fine in a supported Synology NAS as well. But do not think that it will work if it is not explicitly supported by your NAS model. Synology explicitly stops (perfect compatible) cards from add too much really cool functionality to their NAS units. And at least as of now Synology does not allow NVMe drives for storage, only for cache for SATA HDD and/or SATA SSD.The card is a work of art. I rarely see this level of quality even at the enterprise level.I am sure this works well in the compatible Synology NAS units - read the compatibility list and don't think it is just a suggestion.I can't say if this will work for you in a Windows 10 setup (know the risk) but I can tell you that it worked for me. The toughest part was figuring out what vendor Synology used for the NIC chip as the NVMe just worked. Once I found that is was Acquantia I had to figure out that Marvell recent purchased them. The driver was sitting there say, download me and go for it - and I did.My NAS setupDS1621xs+ (does not support this E10M20-T1 NIC/NVMe card)OS/DSM 6.2.3-25426 Update 3My Windows 10 x64 setupMotherboard: Asus ROG Strix-E (bought summer of 2020, cheap but effective motherboard, USB 3.1 Gen2x2, but no Thunderbolt)CPU: 10th Gen i9-10900K (stock speed but will do 5.3Ghz, bought summer of 2020)RAM: G.SKILL TridentZ Series 64GB (4 x 16GB) 288-Pin DDR4 SDRAM DDR4 3400 (PC4 27200) Model F4-3400C16Q-64GTZ (running stock at 2133mhz, quite a few years old)PCIE slot usage: Each of the 2 E10M20-T1 [PCIEx8] cards runs in the 2 CPU-wired PCIEx16[physical slots] - so a x8/x8 slot setup (I am a developer, not a gamer)Good luck

But it really does work great. NAS is soooo much faster with this card installed. I'm using dual 2TB NVMe for the cache. Really happy with this card. Recommended!

Great combo device… just need an SFP version

I hated the fact that my Synology NAS had only one pcie slot, which until this adapter card was released, had forced me to have to choose between using 10Gbe or ssd disk caching with my NAS. I've wired my house with 10Gbe for a couple of years now, so I was looking to this card being released so I could finally get both 10GBe and SSD caching to max out the speed of my NAS. The card did not dissappoint. It was easy to install -- took less than 10 minutes moving my NVME SSD storage over from the old card to this new one. And the 10GBE connection was automatically recognized by the NAS and immediately boosted the speed of the network connection -- allowing me to use my NAS now as an everyday storage for the computers in my household. Great product, very well built with high-quality components and very well packaged by Synology.

Get the most out of your nas with this speed demon!

Synology DSM 7.0.1 worked great with this SSD/10G E10M20-T1 Combo-Card on my older DS3617xs. With DSM 7.0.1, this card let you create two separate cache types in the same Storage Pool #1: One from SATA-SSD's for Cache #1 and then Second from NVME-SSD's for Cache #2, for use in two Volumes on Same Storage Pool... BUT NOT ANYMORE!!MAJOR FUNCTIONALITY DELETED DSM 7.1 that directly adversely affect this combo-card!!!!!Now, Storage Pool #1 consisting of SATA SSD's and another consisting of the NVMe SSD's this combo0card uses, NOW must use separate PHYSICAL DRIVES to create a MULTIPLE Storage Pool #2 (not just Volume #2). For clarity: No, you CANNOT just use free space from your existing Storage Pool #1 to use for a Cache Pool #2 to keep using this card!!! OUCH!!!!!!!When DSM 7.1 released, this issue is now such a major HUGE complaint in the Synology forums, that Synology had to put this FACT in its official "SSD Cache release notes new for 7.1", to try and slow down the title wave of returns they're getting from angry customers like me.Literally, what was working great in DSM 7.0.1 is now IMPOSSIBLE in DSM 7.1 (same storage-pool with multi-volumes NO LONGER SUPPORTED MAKING THIS CARD USELESS).Unfortunately I got this more than 30-days ago, so I'm now forced to toss it on eBay for half what I paid or into the garbage. Basically, Synology's decision to KILL this card with these insane DSM 7.1 limitations being UNABLE to use it for multi-volumes in a single storage pool now, is totally unacceptable!!p.s. This Synology NIC/SSD combo-card, is also SLOWER at 10G than my older Intel 10G NIC, so now I'm forced go to back to the Intel NIC and lose the expensive NVMe flash cache which is just terrible!!!!!!!!!!Update 11/23/22: I tried this E10M20-T1 again with DSM 7.1.1 in ds3617xs, and it's still extremely disappointing how I still get an error that my SATA SSD cache CANNOT be mixed with NVMe SSD cache. And, the 10G performance is lower than my ancient Intel x550 10GB nic which also works fine in ds3617xs. I guess I'll have to sell this E10M20-T1 on eBay, I've held on to false hope for way too long to return it now...

Fast And Good
