I've had this for a day or so now. Plugged it into the Macbook and apparently nothing happened: Snow Leopard does not seem to have built in drivers... but System Profiler *did* recognize it and the machine didn't kernel panic/crash/hang etc.

As the packaging states, this device uses a chipset from Silicon Image *sii 3132*.

I Googled for "silicon image 3132" and found their driver download page.

[...]

I downloaded their latest drivers "* SiI 3132 32 and 64 bit Mac OS X 10.6.x BASE (non-RAID) BETA", dated 1/28/2010, version 1.2.3.0.

Installed those drivers; powered off the machine. Plugged in my drives (Seagate FreeAgent Pro "Classic" 500GB and 750 GB). Powered on the machine. Drives were detected and powered on.

Then I started copying data between them; while writing a large chunk of data from another machine on the network. So far so good. The green lights on the card are flickering, data's being written.

This might not be the fastest eSata adapter but it works; it's cheap; and it's much faster than the Firewire 400 I *was* using before. Only time will tell if the hardware/drivers are stable.

I deducted one star because the card doesn't stay "locked" in the slot. Not sure if this is the fault of the card, the laptop or the ExpressCard 34 standard.

I deducted one star because the manufacturer didn't package the Mac OS X drivers with the product.

*** UPDATE ***
I've upgraded my MacBook Pro to Lion (Mac OS X 10.7); and downloaded the latest drivers: success!
Again - very stable, I've had no kernel panics/hangs etc even under heavy load.

I will add one star back because the manufacturer provided updated drivers even though the hardware is "old" in computer years.

This eSATA Express Card/34 adapter has a Silicon Image chipset (SiI3132). So it works naturally with the most recent beta release of driver (Jan 2010) from Silicon Image in my Macbook Pro (2.93 GHz) running Snow Leopard 10.6.2 (please note that this product does not list Mac compatibility - the drivers on the CD supplied will not work with Snow Leopard). I am using this adapter with a Thermaltake BlacX eSATA/USB HDD docking station. During a test run, transfer rate was about 35-40 MB/sec to a 2.5" 300 GB (Fujitsu), 50-98 MB/sec to a 3.5" (Seagate or West Digital) 2 TB drive. I picked a few of the copied files for checksum, and they look fine. A great performance for the best price I could find on Amazon. I am going to buy a second adapter of the same model for another Macbook Pro I have!

So, with USB-only file transfers driving me insane, I decided to step into the world of eSATA.

What is eSATA? It's a bridge between SATA interfaces, used to connect a computer to an external drive. It's supposed to support transfer rates of up to 3 gigabits per second.

USB 2.0, in comparison, peaks around 480 MBits/sec. FireWire is 400/800 MBits/sec. In theory. In practice, on a Mac, USB 2.0 is always slower than FireWire 400, which tends to deliver as specified-- 400 MBits/sec.

Since Macs until recently had FireWire, there wasn't much need/interest in eSATA in the Mac world.

But 3 gigabits would be kind of cool.

I decided to test this on my MacBook Pro Unibody (last year's edition).

I used this Expresscard, which features a Silicon Image SiI3132 chipset. This has two ports. The card doesn't come with Mac drivers, but I downloaded a set from SI's website.

Test setup:

Config A is an Optimus 5400 rpm SATA drive with a ByTecc case.
Config B is a Hitachi Travelstar 7200 rpm SATA drive with an Eagle case.

Test results:

Config A: 61 seconds to transfer a 1.08 GB Aperture document (many embedded files) via eSATA.
70 seconds via USB.
Config B: 60 seconds via eSATA
72 seconds by USB.

Not spectacular.

So caching can make a big difference, as can the number of files being copied. So I tried a large-file experiment, compressing the Aperture document into a ZIP file (1.02 GB). Since I had established the two drives/enclosures were in the ballpark, I just used Config B.

Config B:
43 seconds via eSATA
35 seconds via USB

Yes, USB was faster.

So bottom line, no dramatic differences.

This card installed itself in Windows 7 without the driver disk. It worked immediately and flawlessly with the StarTech eSATA hard drive dock. Instant success....almost too perfect for a tinkerer type like me.

I've been using this for about 2 months with my 2008 17" MBP and the latest (1.2.5.0) drivers. Results have been mixed. Like a previous reviewer wrote, whether it's this card or Apple expresscards in general, the card just doesn't stay in. I'm frequently seeing the "this disk was not ejected properly" message when I barely move the laptop. I've also been experiencing a lot of kernel panics, usually related to the card coming out of the slot. Usually re-seating the card and rebooting (in the case of a kernel panic) fixes everything. Last night I moved the laptop and saw the disk eject again. This time when I removed and re-inserted the card, nothing happened. No lights, no drive, nothing. I've tried re-seating the card at least 20 times and rebooting 4 times, including twice after re-installing the drivers. I think the card is dead. I wasn't doing anything more than leaving it plugged in on my bed with the drive on the floor below. Luckily my drive also has USB; otherwise I'd be stuck without my data until I can buy an e-SATA card that works better.

All-in-all not a bad product for the price if you can keep it in place and it doesn't break on you.
