Re: PCIe SATA controllers
For JBOD disks the LSI or the build-in Intel or AMD ports seem to be equally as fast since they are all connected to the CPU with enough PCI-e lanes, and for most usage cases it is plenty fast enough. I have had bad luck with at least 2 different marvell chipsets, so won't touch those. One of them would timeout all 4 disks connected to it and the issue seemed to be worse if smart commands were being done (I removed a job that was doing smart commands often, and stability went from weeks to months). It was a 9230 and it acted like it was using a SAS expanders, and some notes I have found indicated a number of the Marvell ones rely on a SAS expander. It was 4portsx6gbit with pcie-x2 and was fast when it worked but unreliable. So I am staying one of the enterprise class SAS cards, or the build-in's from AMD or Intel is all I will use.

Re: PCIe SATA controllers
Hi, > The curiosity is killing me! What do you need > 6+ SATA ports for? I have a 60GB SSD that I use for root, along with a 240GB I use for a Windows VM. The others are 4TB disks I use for my photography and Videos/torrents. The sixth is the BR-DVD I needed two more 4TB to mirror together for data to bring to the colo instead of having to transfer it to our production systems over the Internet. It also became an exercise to learn whether the onboard Intel is as fast as one of the LSI/RAID/SAS controllers, and perhaps it would be faster to use one of those instead of the onboard Intel. > It has an M.2 NVMe slot (which uses four lanes of PCIe) Aren't those "disks" very expensive? And limited capacity? I also don't currently have any, so would have to buy them to replace what I have.

Re: PCIe SATA controllers
Stay away from the <$50 for 2-4 ports, most of them are pretty bad. One of the cheaper old LSI ones. I have one that was bought used and flashed into a pure sata controller. Mine is a: SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] and/or The LSI 9211-8i 6Gb/s SATA +SAS HBA, It is around $80 and is a pci-e x4 card, and with 2 breakout cables you have 8 ports at 6gb/s.
