Onboard SATA host controller (AHCI) with upstream PCle Gen3 x1 and downstream four SATA Gen3 ports. It's a low latency, low cost
and low power AHCI controller. With four SATA ports and cascaded port multipliers, it can enable users to build up various high-speed
IO systems, including server, high-capacity system storage or surveillance platforms
Supports 1-ch PCI Express
Four power-saving modes of L0s/L1/L23/L3
Support L1 sub-state deep power saving mode
Supports SRIS, AER, LTR
Supports SATA LED
Supports NCQ & AHCI SPEC 1.4
Four SATA3.0 (6Gbps) ports
Supports the switching based on the port multiplier commands
Supports SATA Partial/Dormancy power management
Package includes
1. PCIe-TO-SATA-4P x1
2. SATA Adapter Cable x4
3. Screws pack x1

When it's working it's great. Nearly 370MB/s transfers using hdparm -t. This is exactly the kind of thing I wanted to use on my CM4 IO board. It's perfectly designed for this hardware. What's holding it back? The terrible PCIe bugs on. the CM4. It sometimes boots, but other times it causes an instant kernel crash with Advanced Error Reporting errors. If you soft reboot you hit this immediately. If you cold reboot, you can only reliably reboot once every 2 or 3 tries.I really want this to work, but the PCIe implementation on the pi just seems to have too many issues.01:00.0 SATA controller: ASMedia Technology Inc.

There's a few PCI flags I might try to see if that helps. It's a real shame, as it's a standard AHCI driver based solution, so it should just work. I'm very sad and disappointed. I hope there's some way to resolve this, as otherwise I may just return it and look for something else.
