## 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.
