8 Port SATA PCIe Card - PCI Express 6Gbps SATA Expansion Adapter Card with 4 Host Controllers - SATA PCIe Controller Card - PCI-e x4 Gen 2 to SATA III - SATA HDD/SSD

Plugged in, plays, and off to races.This Startech 8P6G-PCIE-SATA-CARD is modeled after LSI HBA and provides SAS-style cabling and reliable drive connections.This is a SATA card, it does not support SAS.Pros:• Works natively with macOS (I'm using Monterey), no additional driver required.• Also Windows and Linux support.• Adds 8 ports, JBOD.• Supports SMART.• Includes SFF-8087 mini-SAS to SATA data cables, which will work with any SATA drive.• Cables included are standard SATA length, 0.5 meter.• Supports SATA port multiplier for additional ports.• Ports run at drive speed as expected, no glitches.Cons:• Not bootable, UEFI does not see connected drive EFI partitions.Notes:• Supports any size drive per SATA spec (this question is perennial).• Drive power cabling not included.• I am using longer 1 meter SFF-8087 cables for a large case with no problem.• I am using a Bewinner port multiplier, ADP6ST0-J05 SATA3 4-port Expansion Card: 1 source port, 5 drive ports, which expands by 4 ports for a total of 12 drives connected to this Startech.• Using a port multiplier means upstream link capacity is shared with all downstream drives: plan your storage layout accordingly. I am seeing drives run at speed over (e.g., 130+ MB/s sustained) to spinning drives over the multiplier.Final words:• This Startech is solid going in.• Before getting this card, I've tried two other PCIe SATA cards with typical SATA cabling (non-SAS) and both were totally unreliable, not detecting drives on some ports, CRC errors on detected ports, caused drive data corruption.• I also tried an LSI 9207-8i which is completely reliable and bootable, but it's not batively supported by macOS, which I need.

As usual for Startech, worked right out of the box with my Intel z790 chipset motherboard. Unlike some other SATA controllers, did not require a firmware update.

Connect to all the drives, looks functional. But only as long as the drives are seperate, as soon as you try to create any type of array the device just falls on it face and fails.. and that's windows. It won't even show up on linux

Worked perfectly to add more internal drive connections for my home server system. Plug and play on Win11 with a z790 Aorus Elite AX. Currently has 8 of my drives connected via breakout cables.

Tried this for my UnRaid server, but kept getting read errors and my drives kept going offline. I tried reseating the cable a few times but the issue persisted. Eventually returned it for an LSI 9300-8i card which is working better.
