StarTech 2-Port SATA III 6Gbps PCIe x1 SATA/eSATA Card, NCQ (PEXESAT322I) | Dual-port, Configurable internal/external, ASM1061, Port Multiplier, Full/low-profile brackets, SATA cable, HDD/SSD

Bought this to add Esata to a Proxmox test box I have been playing with. Easy to install, includes low profile bracket. Picked up straight away on boot, including finding the external drive enclosure that had been originally connected via USB. Volumes were remounted without any reconfiguration and guests were able to start with virtual volumes on the attached drives. Performance seems fine, only used with spinning rust so far, so disk IO more likely the bottleneck than the card. Transfer speed does seem more consistant than when same enclosure was attached via USB 3

Superb card. Plug in and away you go. 8x port multiplyer (JBOD) on eSata ext ports. Fast 6gbs transfer speeds. No dropouts or disconnects. Now the bad news - DOES NOT WORK (YET) ON WINDOWS 10 1809.17763.379. If you are still on revision 316 or lower including builds 1803 it works fine. The fault appeared to be introduced in 1809.17763.348 and Startech support are aware and hopefully working on a fix. Microsoft, as per usual will take a bit longer as getting the required info to the right people is almost impossible. I tried several other cards but this appears to be the only one on the market that supports 8 external drives. So don't waste your time on any alternatives (other Startech models or Marvell branded cards (they all use similar ASM CHIPS/DRIVERS)) BECAUSE i'VE TRIED THEM. They will WORK with 5 drives although the Startech recognised 6? I switched to USB mode (connection) which works fine whilst waiting for the fix. Will update when this happens.

I gave this product 4 stars but only because a very small niggle.... jumpers!!. Once installed it will require a remove and adjust to change your configuration. I purchased this controller to go in a MicroServer, the low profile bracket was a must, and it works without the slightest problem. Driver installation went without a hitch... I installed the card, then the driver, then attached the OS boot drive... checked the boot order and fired it up..... no problem. eSATA is connected to a DAS box and port multiplier shows individual drives.... just as it should do. Now on the wish list of several friends !!!

I've tried loads of these cards from different manufacturers, all claiming that they work with port multipliers (I have an 8 HDD DAS unit, so that's 2X 4 channel multipliers). But in reality, they can only handle the multipliers on one channel at a time. So can't run all 8 HDDs together. But this card actually runs both channels with the multipliers, and does it perfectly. So now I can run my 8 HDD DAS, and can use it as JBOD (which I do) or any available RAID configuration. On top of this, you can use it as extra SATA ports by simply switching the jumpers across the correct pins. Giving you a choice of 2X eSATA, 1X eSATA and 1X SATA or 2X SATA. Very good piece of hardware and a very reasonable price. If I could, I'd give it 10 stars.

Bought this to use with my Microserver Gen 8 as it doesn't support 6GB/s on the internal ports for all of the drives. Also wanted to connect my SSD using full speed SATA! I've tried similar products from different manufacturers, most have performed poorly or caused other issues this has just worked out of the box and no problems running windows 8.1. I am using it to power the storage for my home server and the disk performance using this and western digital red hard drives is fantastic. Very good piece of hardware and a very reasonable price. I have no hesitation in recommending that you buy this!!! I think its a must have for every Microserver Owner (Gen 8)

The quality of this product seems excellent. working as it should

I have an external enclosure with five SATA HDDs. With this device I am able to access each and everyone of these disks, copy, move and erase folders, without any problem. It truly knows port multiplier. Moreover, I am delighted to know that, with the switch of a jumper, I can also use it to add one or two internal SATA HDDs. A winner.

The Startech Dual Port PCI express SATA III Works very Well. Had to take out my Graphics card first in order to slot this in as my GC covers both PCI E slots. Once it was slotted in in works quite well with my Hornettek Enterprise 4x 4 Bay External Enclosure. Shows All 4 of my hdd in this box and a Tad faster than USB3.0. Highly recommended..

内蔵SATAとしても、外付けのeSATAとしても使えるのが便利だと思って買いました。 とはいえ、eSATAでの使用に関しては現在（2024年初頭）では対応機器が手に入りにくいので試せていませんが・・・ 内蔵での動作は安定しており、問題なく使えています。 （注意・SATA/eSATAは排他仕様なので、全4ポート中合計2ポートまでしか使えません）

Works great with Windows 11 25H

Ho acquistato questa scheda perchè serviva Port Multiplier. Su un unico cavo Sata riesco gestire più dischi rigidi. Ed in effetti funziona. Nessun problema. La velocità è nella media secondo lo standard Sata.

I needed this to put an extra SATA3 port on my older Z77 motherboard along with adding an E-Sata external port (yes, E-Sata ahaha!) I have an external IcyBox HDD bank and needed to connect it a bit quicker than USB 3.1 would do i.e. 6Gbps SATA Vs 5Gbps USB. Anyway, had a few boot up issues until I worked out what I was doing wrong (my fault, not StarTech). It is now up and running reliably and with the silly 'jumper switches which I hate (very fiddly) I can decide if I want 2 more SATA ports for my HDDs OR if I want 2 external E-Sata connections OR one of each. It is important to know that you can only have TWO of the ports operating at once - any combination of SATA or E-Sata but only TWO. Once you understand and are happy with that it is a great device to have on your machine. IMPORTANTLY, this card has a PORT MULTIPLIER. This means that any one of the SATA or E-Sata ports can handle MULTIPLE HDDs. If you tried this with a normal port WITHOUT a port multiplier you would have issues. I now have FOUR HDDs working from just ONE of the E-Sata ports on this StarTech card. It really is a remarkable little card. More ports would be nice but it is all I needed at this point. I have found StarTech very good with support in the past for other devices - I just called them for some advice on setup and they were great. The quality is more than worth it so don't be tempted by similar things on the web which are much cheaper. StarTech engineer these things properly to last - no bad surprises. HIGHLY RECOMMENDED.

Compré en primer lugar una tarjeta expansor de 2 puertos eSATA ppr 17€ de otro fabricante, pero como resulta que ni traía drivers ni daba soporte de ningún tipo, la funcionalidad de añadir discos en caliente no funcionaba. Como ya había comprado productos de esta marca con anterioridad, y funcionan a la primera y dan un soporte en menos de 24h labofables, no me lo pensé más y compre calidad. Como esta tarjeta viene con si driver, es instalarlo y funcionar a la primera.
