## Overview

The Synology E10M20-T1 adapter card combines a 10Gb Ethernet port with dual M.2 NVMe SSD cache slots in a single PCIe expansion card, designed to significantly boost network bandwidth and I/O performance on compatible Synology NAS devices. Ideal for professionals seeking faster data access and efficient storage management, it supports multi-gig speeds up to 10 Gbps and frees primary drive bays by offloading cache duties to dedicated M.2 slots.

## Description

Synology E10M20-T1 helps you boost I/O performance and network bandwidth simultaneously using just one PCIe expansion slot on your Synology NAS.

Review: This SFP28 E25G21-F2 25Gbps card is finicky about which cable it gets plugged into the ports to work at 25Gbps. You must purchase one of the cables from the Synology compatibility list. If the cables are not from the compatibility list, it will only work at 10Gbps. We used the OEM Mellanox DAC cables which worked flawlessly. desertcart.com so-called Mellanox SFP28 cables don't work at 25Gbps (we tried 4 different sets). A switch with SFP28 25Gbps ports will be required to operate at 25Gbps. Your Workstations will also need SFP28 25Gbps network cards plugged into pcie 3.0 or 4.0 ports x8 to benefit from the 25Gbps network speed now available to your Workstations. Your NAS will need the fastest NVME drives installed in the cache slots in order to saturate the network bandwidth. One clause tho, pcie 3.0 NVME cache drives don't fully saturate the 25Gbps network. The Samsung 980 pro gen 4 drives do better than the gen 3 drives by a slight amount read, but notably better with write speeds. Even the gen 4 drives don't fully saturate the 25Gbps network installed in the NAS pcie 3.0 cache slots. Only if Synology would have installed pcie 4.0 nvme cache ports into the current NAS systems. Also trunk porting the NAS does nothing for speed, just redundancy. Must be a Synology thing? Our file access speed has more than double from our old 10Gbps network, now that all these hiccups have been ironed out of the Synology card. The changeover to this Synology 25Gbps network could have been easier with more technical literature from Synology. Hope this lesson of trial and error helps others purchasing this card to upgrade their NAS.
Review: Supplied a card with a broken factory seal and tried to repair it under packing tape.

## Questions & Answers

**Q: Does this work on a pc? is therea plx switch chip that gives full bandwidth access to both the pcie 3.0 x4 m.2 drives and the aquantia 10 gbe nic?**
A: I bought this for my DS1621xs+, hoping by luck it might work, but no.  :(  
But....Win 10 sees the 2 NVMe just fine, 5000MB/s.  The NiC needs a driver.  I will try the Marvell/Acquantia 107 driver soon and may update here.   This card in a PC would be a GEM.  I am hoping that Synology will one day allow this to act as a 2nd NIC and 2nd NVMe cache pair.  They sure don't want us using ANY NVMe for storage.  :(

**Q: Is the SSD on this card only used for network cache?**
A: No - The SSD has no special relationship with the Ethernet interface, it's just a way to get two functions on one card. So you'll get the benefit of disk I/O caching regardless of whether that I/O is coming from the network or not.

**Q: Why do we need additional m.2 adapter, sine the newer Synology comes with internal m.2 slots?**
A: You might have an older model that would benefit from cache drives.

**Q: Anyone using this on Ubuntu Linux?**
A: I have used it on both Ubuntu 22.04 and Windows 10, and both work correctly with no manual driver downloads for install. Highly recommend if you want 10g and two m.2 slots for a limited pcie 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/s See 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# AQC107 Note: Marvell purchased Acquantia recently The 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 setup DS1621xs+ (does not support this E10M20-T1 NIC/NVMe card) OS/DSM 6.2.3-25426 Update 3 My Windows 10 x64 setup Motherboard: 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
