3 out of 5 eggsMaybe not so great.

Pros: Follow up review. One year later.

It works. But.

Cons: I was really happy with this card and the 10MB/s transfer rate I had on eSATA. Then I plugged my external storage system into my new computers eSATA3.0 port and the transfer rate doubled.
When the details on this device says it has a internal eSATA 3.0 port and a external eSATA port it doesn't say the external port is eSATA 3.0, from my experience is isn't.

Other Thoughts: The usb 3.0 port gives me around 48MB/s transfer, about the same as the eSATA on this card. The eSATA 3.0 port on the new machine runs over 100MB/s.

1 out of 5 eggsNewegg "WOW".

Pros: None

Cons: I installed this card, it worked but when I tried to put my computer to sleep it would wake right back up, when I tried to shut my computer off it would start back up. I had to shut the main power switch off for the computer to stay off. I called the Mfg. tech support and there big help was "its a bad card" no offer to replace it or anything else, I will never buy anything from this Mfg. again.

Other Thoughts: Newegg return was so easy I could not ask for a better retailer, NEWEGG is the best!!

1 out of 5 eggsDO NOT BUY!

Pros: It has an IDE port, if you still have a drive that needs it

Cons: This card caused a new build of Windows 7 to crash CONSTANTLY. After 30 - 40 minutes, the OS would freeze up and then I would get the BSOD. Furthermore, it added an additional 30+ seconds to total boot time. Once I removed this, Windows 7 booted in less than 20 seconds and has not crashed since. This card is totally WORTHLESS!

Other Thoughts: I have been building PC's for 15 years. It is a hit and miss affair sometimes. But, this card is definitely not worth the risk. The machine I was building was for my son, so no harm done professionally. But, if it were for a paying customer, they would be justifiably upset.

2 out of 5 eggsNot what I had expected

Pros: Still looking for some pros, but can't find any so far.

Cons: A bit slow if you ask me.

Other Thoughts: I transferred 20G of data over from an external esata HDD to a Magnum 64Gb USB flash drive. The flash drive has been extremely fast in the past when transferring files from other HDDs with the speed rate of 23Mb/s. While entering this review, the copy transfer rate is averaging @ 10M/s. My next step is to pull this card and put in a StarTech PCIe esata card to see if it will be any faster. I’ll let you know the outcome later.

5 out of 5 eggs

Pros: Card does exctly what it is supposed to do. Hot swap works fine with External Hard Drives. Way faster than USB.

Cons: Would have like to have had two plug-ins instead of one.

4 out of 5 eggsSo far, so good

Pros: Easy to Install. Needed to load drivers to make EDI port work, but no issues. Everything works - with a little tweaking as noted in the cons. Very Fast port.

Cons: I cannot seam to get the system to go into BIOS when the card is installed. I can Control-M into the Raid Config (which I'm not using), but I cannot get the MB BIOS to come up.

Other Thoughts: Even though BIOS is set to Boot from Primary Hard Drive install on MB Port, the system tried to boot the drive using the internal SATA port. This should not be a problem for most people. I found out because the first drive I connected has previously been used as a primary drive and the system tried to Boot from it (and Blue Screened). A simple swap of cable to another drive that had never been used as a primary fixed the problem.

5 out of 5 eggsNice Card

Pros: This is the 4th day I have been using the card. I installed the card and powered up the computer with my new eSATA device. The computer loaded drivers for my new devices. I did get a fail for a ATA interface device. I pointed it to the CD and it loaded the correct driver.
The port multiplier works good. I am running this with a 4 drive external USB/eSATA enclosure.

Cons: None.

Other Thoughts: Small foot print. Will allow me to use a couple old IDE devices if I choose to. The eSATA is so much faster than a USB 2.0 drive.
