2-Port SATA-III Raid 1 & 0 PCI-Express Controller Card (PEXSAT32)

The PEXSAT32 2-Port PCI Express SATA 6 Gbps (SATA 3.0) Controller Card offers simple connectivity between a host computer and SATA 3.0 devices - a cost-effective solution for connecting high-speed storage, such as High RPM Hard Drives and Solid State Drives (SSD), which in turn allows for easier data backups and archiving.

With full support for SATA 3.0 hard drives and data transfer speeds of up to 6 Gbps, the adapter card features a native PCI Express single chipset that provides enhanced compatibility, reliability and performance for external SATA 600 MB/s storage needs.

The controller card is backward compatible with SATA 2.0 devices, providing the versatility to use older storage, and features port multiplier capability with command-based and FIS-based switching for connecting multiple external hard drives to a host PC through a single external SATA connection.

A dual profile solution, the SATA 3.0 controller card includes a low profile bracket for installation in slimline or small form factor computer cases.

- Number of Ports: 2
- Raid: 1 and 0
- Includes normal and low profile backplate
- Max Data Transfer Rate: 6Gbp/s
OS Compatability: - Windows® XP, Vista, 7, 8, 8.1, 10
- Windows Server® 2003, 2008 R2, 2012, 2012 R2, 2016, 2019
- Mac OS® 10.6 to 10.14
- Linux 3.5.x to 4.11.x LTS Versions only

Good but why not 4 SATA ports?

Only scored this an 8/10 as for ~£35 quid I’d have been happier with 4 SATA ports rather than just 2 - you’d think the 7 mechanical and 3 SS drives I have would be enough eh? :D

Anyway it’s rocking along nicely in my Asus Z97-Pro board and I can now use my optical drive again as I’d used up all my boards SATA ports, plug and play (Windows 10 x64) comes with a driver disk (I assume for RAID) which for my uses wasn’t needed.

Fine for use where VT-D is not in use

Worked well, wont work currently with VT-D Virtualisation on Linux

Worked for years on a server 24/7 until I upgraded the CPU to support VT-D which I require now.

Unfortunately the bug above renders the system inoperable - attempting to find a low cost replacement to support 2xSATA ports, so I can boot with VT-D enabled in the Linux kernal.


Works great

First off, directed toward Robin from London: If you did proper research on PCI-E bandwidth, you would have realised very early on that PCI-E 1x has a top speed of 250MB/s one direction (but because it is a parallel port, it is 500MB/s). To blame this on OcUK is quite childish as you could have avoided this by actually knowing what you were buying.

That said, this card works fantastically and for people who bought their PC just before SATA-3 came out or who need extra ports, it is the most cost-effective upgrade going at the moment! Coupled with OcUK's great delivery times and lightning fast service, this deserved top marks!

Does a great job!

Already had an Adaptec 1430 card with 4xSata II ports for the past 4 years but wanted to try SATA III as a precursor to buying an SSD. I'm not so sure whether I'd buy an SSD right now as this card combined with a new Hitachi Deskstar 7K1000.D gives impressive performance whose small file read speeds are comparable to some SSD's.
Installation was easy as pie. Windows 7-64bit already has the drivers.
Great value little card (my Adaptec 1430 card cost

The card works at it's top speeds if it's installed in a PCI-E slot at x2 or higher, and my mobo doesn't have any, just x1.

Consequently, I'm getting the same speeds if I'd just plugged my SATA 6Gbp SSD drive into a built-in SATA2 port. Wasted

A little slow, but does the job

I bought this as my mobo lacks proper Sata 6GB/s support - the card does the job instead. Pretty much plug-and-play and trouble-free but there are a couple of things to think about if you're considering it.

Firstly, it uses the Marvell chipset, which may lead to lesser performance with some devices (including SSD's).

Secondly, the card won't perform well if it's installed in a small 1x PCI-e slot, as the bandwidth to a 1x slot will be limited, giving poor read/write performance. In a 16x slot, it performs a hell of a lot better, though my SSD performance still lags behind a bit due to the Marvell chipset.

In all, a cheap way of adding 6GB/sec support - provided it's in the right PCI-e slot, and with a device that doesn't mind the Marvell chipset.

Ideal Solution

Bought this card in conjunction with a Vertex 3 120gb SSD as my mobo doesn't support SATA 3, looking to upgrade to a Sandy system later in the year, I ran benchmarks using my SATA 2 controller and it peaked at R/W 283/267. After installing this card R/W was 430/296 still not top whack for a Vertex 3 but its still respectable(ish). Just gonna have to do some more overtime to pay for a Sandy system to unleash the full potential of the SSD.

So if like me you lack some SATA 3 ports then your not gonna regret getting this little card. Not sure if there is any drawback to it being a Marvell chipset on the card but still does exactly what it says on the box.

Running under Windows 7 Home Premium 64bit on a Gigabyte GA-EX58-EXTREME (rev. 1.0) with latest BIOS (F12)

Windows Server 2008 R2 SP1

This controller card will work with Windows Server 2008 R2 but to save you some head scratching don't bother downloading the device drivers from the StarTech web site as they aren't recognised by the OS; instead point the driver search path to the root of the supplied CD. Note I say the root and not the folder containing the drivers for this device.

When the device is installed it will appear under the System devices section within Device Manager not the Storage controllers section as it states in the manual. Also, as already noted by another review, the device properties will state that no drivers are installed.

So, how does it perform? To be fair I require a second sold state drive to conduct real world tests. Using an Intel 510 Elmcrest 120GB drive, HD Speed shows a sequential read rate of ~355MB/sec using a 4MB block size. The write test is destructive so I'm not going to run that :->

Startech 2-port sata III pci-e card

Excellent value for money, does the job of handling my C300s in raid perfectly.

Bob 2010-11-03

Does the job

Bought this to run new Crucial C300 256GB drive (see seperate review).

I have used this to do a fresh install of Windows 7 on the SSD drive without problem. Windows 7 has support for it.

Has its own little BIOS so you can configure RAID0/1 if you want.

Originally only got 195MB/s read speed from drive until I realised problem and put the card into a proper PCI-Ex 2.0 slot rather than 1.0 slot. Bandwidth was then 5Gb/s (not 6) and read speed was 345MB/s which is about as good as you could get.

Might be nice if it had a little hard disk LED extension lead as when mounted in back of case your may not reach (like mine) so I have no idea if disk is active.

Also although Windows 7 seems to run fine with it, it does report in device manager that the Marvel 91xx Config ATA Device doesn't have a driver.

So if your paying big bucks for a SSD for the price of this its worth getting I think.
