PCIE to 4-Ports 6Gbps SATA III Card for Windows Server, XP, 7, 8.0, 8.1, 10, 11(32/64), MAC OS and Linux Desktop PCs-4X 6Gbps Max SATA 3.0 None Raid Ports-Support AHCI Boot Up (PCE-G2S4)

Just what I needed

I have a motherboard that has only 4 stata slots, and I need 1 more. I also need ALL of them to boot, because this computer is to have three operating systems on board, and capable of booting from three removable drives. That way I don't have to remember which drive bay is bootable. I tested out by booting Linux Mint on it in a removable drive bay. It connects on boot before the OS is loaded. I've had others that didn't perform as well as this card, so for now it is the best I've had.

My project for a low power/low noise home NAS box started off with a refurbed ASRock J4105 fanless quad core celeron motherboard with 8 gigs of RAM, but with only two on board SATA III connectors. This 4 port card allowed me to set up 4x hot swap 3.5" bays to a single card. I configured Open Media Vault to use two Hitachi 3 TB drives in a mirror configuration, and when transferring movies from my workstation to the OVM NAS, the gigabit connection is the rate limiting factor (maxes out around 83 MB/S, which is fine for a home system).So it works, does what I need it to do, supports software RAID on my NAS, and I haven't used any other functions built into the card simply because I just needed the extra ports.This card uses a PCIE 2.0 x4 connection, which has a max bandwidth of 2 gigabits per second, which is fine for a NAS on a gigabit LAN since the network is half the bandwidth of the card. If you are looking for a full bandwidth experience in a workstation for things that require high bandwidth such as video editing or content creation you should get a PCIE 3.0 x8 card or PCIE 2.0 x16 in order to get a SATA controller card that can max out the 6 gigabits/second SATA link.

Installed the card in my system which uses an MSI B450 Tomahawk Max motherboard. I bought this to add an internal DVD-ROM to my system, which was out of SATA connections; and for future expandability. Giving 2-stars due to easy install and no need for drivers on Windows 10, but I've had too many issues to recommend it as even mediocre. See below for details.THE GOOD: Easy install and Windows 10 recognized card with no driver install required.THE BAD: Installing the card had a massively negative impact on my system boot time. My boot time increased by at least 4 times in length. Most of the time it seemed to take closer to 6-8 times as long as without the card installed. Basically, installing the card caused a very fast booting system to now boot very slowly. Additionally, the read speeds from my DVD-ROM (which I had in a previous system) seemed noticeably slower when connected to this card than in the past.THE UGLY: Once the card was installed it interfered with or otherwise impacted the current SATA controller on my motherboard in such a way that one of my current hard drives stopped being recognized. Since this was my data drive, with the card installed I lost all access to my personal files and data.THE TAKEAWAY: I may continue trying different connection options to see if I can get everything to work correctly, but at the moment I'm leaning towards returning this card if I can and trying to find an option from a brand I'm familiar with. But I wanted to share my experience since it seemed to be different than many other reviewers.

It was easy to install and my motherboard and Windows 10 Pro recognized it right off.Windows 10 Pro installed default drivers right way, but then I installed the drivers from the disc.it seem's to be 6GBps speed it matches up with my motherboards SATA connectors and responds accordingly, I did not even have to switch the switch on it to install it.now as long as I have open racks for HDD, Driver and SSD drivers I'll be able to install more backup drives for my system.

This add in card works great to add four more SATA ports. I’m docking one star because having a PCIe 3.0 x1 interface makes the maximum data bandwidth ~1 GB/s. Adding two SATA 3 SSD drives can saturate this link at maximum transfer speed meaning any additional drives added will cause all the drives to reduce their maximum performance. Theoretically four SATA 3 SSD drives would be limited to 250 MB/s each. Most of the time this probably wouldn’t be an issue unless you’re performing some very heavy data reads and writes.

This PCIe device was recognized immediately by Proxmox (Debian) and functions perfectly out of the box, so additional setup needed - plug and play. If you're using Linux this is the one you're looking for.

I am using this controller to add extra SATA ports to my home NAS. It functions properly with no additional involvement from me with TrueNAS and is able to support steady 100+ MB/s read write speeds from WD Red+ drives over a gigabit network
