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 22.214.171.124.
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.
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.
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.
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.
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.
43 seconds via eSATA
35 seconds via USB
Yes, USB was faster.
So bottom line, no dramatic differences.Read more ›
All-in-all not a bad product for the price if you can keep it in place and it doesn't break on you.
