Add 4 Internal SATA III (6Gbps) ports to a computer through a PCI Express x2 slot. The PEXSAT34RH 4-Port PCI Express 2.0 SATA Controller Card with HyperDuo adds 4 AHCI SATA III ports to a computer through a PCIe slot (x2), delivering multiple internal 6Gbps connections for high-performance hard drives and Solid State Drives (SSDs).
Featuring HyperDuo technology, the SATA card offers SSD auto-tiering which lets you balance the performance advantages of SSD storage with the cost-effectiveness and large capacity of standard hard drives. By combining SSD and HDD drives into a single volume (up to 3 SSD + 1 HDD), HyperDuo discreetly works in the background to identify and move frequently accessed files to the faster SSD drive(s) for improved data throughput - up to 80% of SSD performance! (The HyperDuo automatic storage tiering feature is compatible with Windows XP, Vista, 7 and 8 only).
The PCIe SATA controller card supports Port Multiplier (PM), enabling multiple SATA drives to be connected to one port over a single cable, for a total of 7 drives (Up to 4 drives through PM on one port, and a single drive to the remaining 3 ports). Plus, the SATA controller card offers an effective hardware RAID solution, with native RAID (0, 1, 1+0) support.

Rated 5 out of 5 by from Great functioning Hi! I like the product, but I have a question. How can I disable the hot swat function under windows 10 in single disc mode? I was able to disable it in windows 7 in Device Manager, but in win 10 I can't find this function.

Rated 5 out of 5 by from Works with FreeBSD I bought this as a replacement for a faulty SATA 2.0 controller. Works out of the box, although for some strange reason only after I booted the second time, examined the BIOS menu with ctrl-M, and figured I didn't need to change anything for JBOD mode. Overall seems good product. Only minor disadvantage is that it is only a PCIe 2.0 x2 lane, so I'm not mistaken that's max 1 GByte/s, whilst 4 disks could theoretically generate 4x 6 Gbit/s = 3 Gbyte/s (minus overhead).

Rated 5 out of 5 by from Missing JBOD As with a keke27, I too am unable to find a JBOD option using the "card bios" method for installation in a linux rig. Two disks are plugged in, and the only options are Raid1 and Raid0.

Rated 5 out of 5 by from Simple, functional, and fast. I had to do very little to get this working. Installed in a Linux server, booted into the card BIOS, configured the RAID and done. It presented the drive to the OS as configured, and throughput was better than I expected (first time using a StarTech controller, so I WAS apprehensive) given the list price. The small size makes for it not getting in the way inside the case or obstructing airflow. I received this product in exchange for an unbiased review.

Rated 5 out of 5 by from Effective! Fast as! wonderful. Amazing for Gamers. Hello, recently purchased. Spiceworks poster. Used this recently in a Gaming PC build, 2x 970 evo 512GB with 1x 6TB WD Blue = up to 800mbps throughput from or to NVME System drive. I had initial issues with conflicts but I eventually got the card and my system working. copied my existing HDD to it, launched some games. Games like total War: Warhammer have gone down as much as less then a minute from a fresh boot not to mention No man's Sky which will load in about a minute. HyperDuo is simply, incredible. Needed this card as I had a small case and I really needed more space for games, two of my four sata MB headers were blocked by fans so I saw this card and was keen to try the HyperDuo feature.

Rated 5 out of 5 by from Working OK- Windows 11 (Dell Precision T5610) Firstly I suggest you disconnect all other SATA drives on first install as I suffered a corruption on my system boot SSD disk following installation of the card. It seems very unlikely this was an unlucky coincidence. I've not seen a CTRL-M during any boot though did not exhaustively adjust PC BIOS settings.I have UEFI mode and secure boot so perhaps this is a factor. With all other SATA disks disconnected I followed the instructions to create a Rufus DOS boot disk and the UEFI firmware installed OK.I then attached the SATA SSD boot disk and reinstalled Windows 11. Installed the drivers and the adapter was detected OK. I then connected a couple of 4TB SSD, these were detected OK. Used the MSU Windows software to create a mirror (RAID 1), no issues. I tried the Marvell CLI but didn't get far and the help is sparse on this though I'll find documentation with a search.The email alerting capability looks useful though with modern authentication becoming the norm the SMTP configuration provided will require a relay.

Rated 5 out of 5 by from Windows 10x64 Update 1809 problem Boot under 1809 possible, yet system significant slower than under 1803. Worst: my 4 RAID 10 HDD with the OS on it are shown as "removable drive". No proposals from MS & forums do the fix up-to-date.

Rated 5 out of 5 by from Great value Been using it for almost two years now and it's worked consistently good. Used it to connect an internal 4TB drive and my comp case's top HDD docking station, and it does better than expected at both (allows drive hot swapping without issues). Data transfer speeds are just as expected. Totally recommended.

Rated 5 out of 5 by from UEFI I was glad to find new UEFI bios for the card, yet my external drive connected does not show anymore. When viewing in MSU Software its seems to be a problem with a SATA 3G/Bit fault in the controller. My 6G/bit drives works fine. Is there a solution to this problem.

Rated 5 out of 5 by from Work Really Well I bought this product around 3 years ago and it is working flawlessly. The HyperDuo function is wonderful and helps me to use a bigger HDD with high performance at one affordable price.

Rated 5 out of 5 by from Nothing but problems... I purchased this card so that I could add 3 additional SATA hard disk drives to my PC, because my motherboard's 12 SATA ports are all being used. However, the card has caused me nothing but headaches. When I first installed the card, it appeared to be working fine because the hard drives all showed up during POST. It booted into Windows and the hard drives all appeared in My Computer and in disk manager... But that was only for less than 5 minutes. After that, the three hard drives vanished from My Computer and Disk Manager as though they had been unplugged. In an attempt to make the drives show up again, I restarted my computer, only to have it freeze during the Windows boot logo three times in a row. When I read that freezing during boot was a sign of a faulty card, I ordered a second card thinking that I must have just been unlucky with the first. But the second card has the exact same issues as the first! This means that either my luck is REALLY bad, or (more likely) most/all of these cards are defective or bad by design. The three hard drives work properly when attached via a SATA to USB adapter, or when attached directly to the motherboard with either of two brands of SATA cables, so the drives and cables aren't the problem. In my trial-and-error tests, I found that the only thing that differs between when the hard drives work and when they don't is when they are attached via this card. Therefore, it'd definitely be better to look elsewhere if you need an easy to use, stable, and reliably-working PCI-e to SATA card.

Rated 5 out of 5 by from finally my server recognises all drives I had a bit of an ordeal installing this device and thought I would have to send the sata expansion card back, ALWAYS read reviews before you buy something unless you don't mind losing the cash. I found that the BIOS was registering all of the drives that were plugged in, the issue was when I booted into the OS, the drives disappeared. I looked online and loads of people had the same issue and complained to startech. I nearly gave up but went back to it. the responses from startech to the reviews hinted that newer chipsets on motherboards might not be compatible, with this I went back to the bios to take a look around, I started disabling things that suggested to me that they could help, ended up being IOMMU grouping. It was set to Auto by default so I disabled it and the drives appeared once I booted! tldr, IOMMU is cool but doesnt always work.

Rated 5 out of 5 by from Missing JBOD On the Tech Specs tab it states that JBOD is supported. I bought this card solely for this purpose. It took me hours to figure out that JBOD is NOT supported. It seems to be an adequate card in general, but, for me, it was a waste of money and time.
