1 out of 5 eggsNot friendly with Windows 2003 Ent. Server

Pros: It has a pretty purple color.

Cons: The installation process was that of a garage shop operation. You could not use the standard Windows installation of new hardware, required to manually install driver (not that hard to do, but it's a red flag).

Had three devices attached (one with port multiplier and two singles), would lose one of the single devices after about 5 hours. Removed the device that it had problems with and replaced it with a new Mybook 1TB device and then the port multiplier device was unable to be seen by Windows. Repeated process several different ways, all ending up with failure of one drive or another.

I installed this device in an attempt to take advantage of the speed provided by an Express Card. These devices all worked fine with a 4 port PCI-X card purchased from NewEgg.

Other Thoughts: Maybe it works well on a Mac.

5 out of 5 eggsWorks for me...

Pros: On a early 2008 Mac Pro.: I am using this to interface with two port multipliers into five drives each with plans to double that in the future. It went into my Mac Pro easy as pie. No issues at all installing hardware or software. I have only be actively using it with the port multiplier system for a week using two port to drive 10 drives. Prior to this I ran four cables to four discrete drives and it was happy as a clam in mud, although be sure you get the right cables--eSata not Sata, or eSata to Sata.

Cons: None so far.

Other Thoughts: I have not pushed a lot of data through these yet. I've occassionally copied entire TB drives across the interface. My Time Machine backups were through the 5th and 6th Sata ports.

This is a nice option with port multipliers for backing up large amounts of data.

I plan to add a RAID card internally to pump up my internal disk access where I need it. I'm happy with it, and if it ever fails, I'd purchase another one.

4 out of 5 eggsGood Product

Pros: Enabled me to add additional eSATA devices... my motherboard had one eSATA port and I needed more... this gave me four more eSATA ports. Their tech support actually answers emails in a timely manner if you have a problem. I would have given 5 stars but I had some problems, but it is a good product and I would buy it again.

Cons: The installation CD had some disk version number or MAC driver version number only printed on it, and based on an earlier review here saying the Windows driver wasn't included, I thought I had to download the driver which was no problem, but later I discovered it was on the CD after all. The readme directions were not accurate... it said the driver was signed and it turns out only the Vista driver is signed and not the XP one making me wonder if the driver was the correct one when I got the unsigned driver message, and particularly after the card in Device Manager was called not "Tempo SATA E4P" as the directions said it would be called, was identified as"Sonnet Temp SATA Gen 2 PCI Express Adapter", and also after it appeared to not function... the reason turned out to not be Sonnet's fault... see below. I was also surprised at how careful I needed to be when tightening the mounting screw as the card would twist if I tightened the screw too much... no other card has ever done that!

Other Thoughts: The card appearing to not function turned out to be caused by the super garbage quality Thermaltake eSATA cables that I had, and I had to loosen the mounting screw to the card and plug the cables into it first, jiggle the cable around to seat it... as the plug was so fat it would overlap the socket and the metal of the case dividing one slot from another, and wouldn't allow the plug to seat and connect properly unless you removed the card mounting screw, pushed the card to one side, seated the cable, and then tightened the card mounting screw with the cable in place.

Too bad NewEgg doesn't carry the high quality Sonnet locking eSATA cables that have a locking screw device to hold them securely in place, or even the SIIG cables that seem to be high quality accoring to other reviewers, as I would have included those in my order if they had been available instead of now having to order them separately from Sonnet or SIIG and pay more shipping. Please stock those NewEgg!

2 out of 5 eggsgreat performance, poor reliability

Pros: great transfer speeds, easy installation into my Mac G5, loads of SATA headroom

Cons: I had this card in service for 14 months and it began to fail intermittently. At first i thought it was the drives till i replaced them with known good drives. I ordered a new card (with a completely different layout and chip set as compared to the board from 14 months ago, BTW) and all is well again. A 14-month life for an interface card is lousy.

Other Thoughts: It offers the best SATA performance going, hope the new chipset brings a lot more reliability.

4 out of 5 eggs

Pros: 4 ports of Sata goodness

Cons: NO drivers included for XP. There's a single Mac image (.dmg) file on a CD. The instructions say for XP users to go to a link provided, however the link doesn't work. Sonnet's website lists drivers for them which install in an almost non-standard method.
