Work of art, even works great on my z490 Asus Strix motherboard with i9-10900K running Windows 10

2021年2月26日 - 已在美国亚马逊上发表

尺寸: D) 1ポート RJ-45 + 2スロット M.2样式: B) 10-NIC + SSD缓存已确认购买

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

Not plug-n-play with windows 10 pro and no drivers from Synology.

2020年1月1日 - 已在美国亚马逊上发表

尺寸: RJ-45; 1 port样式: E10G18-T1已确认购买

Technically it's only supported to work with Synology. But that's not why most people end up here on amazon. Win10 Pro will detect but cannot find a driver. It's not plug-n-play and Synology website doesn't even have any driver support. To get this to work you'll need to download the Aquantia drivers from Dell or any other vendor using the same chip. 2 stars because it's a generic card that's overpriced and in return you get a crippled product from Synology. You shouldn't be buying this, instead get another brand with the same Aquantia chip and a non-bloated price

Real world use case with Synology encryption bottlenecks a problem

2019年10月16日 - 已在美国亚马逊上发表

尺寸: RJ-45; 1 port样式: E10G18-T1已确认购买

Summary: If using this with a Synology with encrypted shared folders, for solely large file transfers, there is a marginal benefit to the increased speed that 5gbe or 10gbe provides, but once you start real world use cases of thousands of file transfers, then the benefits evaporate.

Our Synology use case is routine archive storage for laptops capped at 2TB onboard storage.

We recently added a 10gbe card (Synology 10Gb Ethernet Adapter 1 RJ45 Port (E10G18-T1)) to be able to direct connect our DS1817+ for non-Thunderbolt laptops via a USB 3.0 Type-C to 5GbE Adapter (QNA-UC5G1T) by QNAP. On unencrypted shared folders to a 5 x 4TB WD Red SHR2 array or to a single Samsung 850 EVO SSD we get steady 390 mb/s transfers up and down. But, with transfers to encrypted shared folders we only get about 170 mb/s writes and 350 mb/s reads from the Synology. With a direct attached 1gbe connection, the writes and reads are about 120 mb/s to and from encrypted shared folders. For solely large file transfers, there is a marginal benefit to the increased speed that 5gbe 10gbe provides, but once you start real world use cases of thousands of file transfers, then the benefits really evaporate (with encrypted shared folders).

If you search hard, you can find other testing that confirms that Synology encrypted shared writes are capped at around 170 mb/s no matter what you do to try to work around that bottleneck.

Encryption is a real bottleneck on Synology. But, you have to be crazy not to enable encryption if you care about security at all. The most likely way to lose your data is to have someone physically steal your hardware.

In short, if use encrypted shared folders, then there is marginal if any real world benefit to using 5gbe/10gbe on the Synology NAS.

Hardware ware is perfect. Software need inprovements.

2020年9月10日 - 已在美国亚马逊上发表

尺寸: D) 1ポート RJ-45 + 2スロット M.2样式: B) 10-NIC + SSD缓存已确认购买

Mixed feeling about this.
Hardware is perfect - everything works out of the box with 2 Samsung Enterprise Class 2210 drives however very little performance improvement in day to day usage.
Tried both Read-Wright and Read Only setups, Each with "skip sequential I/O" ON or OFF.
Very little real life performance improvement over none cache setup.
Installed in DS1819+ and mostly use for Plex, Moments, Computer Back Ups and Surveillance station. Didn't notice much improvement in nether of this apps load speeds or less access to HDDs - same constant noise HDDs been accessed even with Read-Wright with "skip sequential I/O" unchecked.
Gave time for cashed to be populated and with R-W-SecI/O unchecked my raid filled 750-800G out of 860G or so withing couple of weeks.
Hope the improve Cache logic with upcoming DSM7.
For home use I wouldn't buy this considering cost (650USD set with 2x 960G NVMe SSDs). Improvement simply is not there. I would rather but 2 more 14-16TB HDD instead and 20$ 10Gbe el-cheapo card.
