In regards to my "30-hour delivery" drive from NewEgg thread...
I hooked up the drive using a raw Lacie quad interface controller board, with an eSATA cable to my Hackintosh, downloaded the free AJA System Test utility, and tested speeds around 130MB/sec read, and 120MB/sec write.
Being only a backup drive this far exceeds my design requirements of ?80MB/sec which is the max speed of my main drive. Also good to know the eSATA works on the mobo without any issues. Only 3gbps eSATA on this system, but that's plenty for just one drive.

Which model drive was that? Like... SPECIFICALLY. That's pretty impressive for a single drive,
and I'd like to know which one it was.
Of course I wanted that info without clicking your links.....
(duh)

Yeah, good for a 5400rpm drive anyway. Not sure how much it will slow down for lots of small file transfers, but it seems at least for now that the boot drive it will be backing up is the slower one.

Update: The drive appears to have failed already.
It started out fine, backed up some data yesterday, turned it off, back on today, tested the speed, backed up some more, unmounted it fine. Then when I turned it on again it didn't mount. Disk Utility saw it but couldn't repair it, I tried a zero all format, didn't take.
Now it won't mount at all. Will try again in the morning. 8-)

With speed like that, I may have take mine out of the USB case for DVR backup, and use it for something that could benefit more from such speed :-)
I remember building a four drive striped SCSI RAID array and getting it to pull over 38MB/sec and thinking THAT was screaming... then a few years later w/ 10K drives building out a similar U2WSCSI array that ran hotter than heck, that pulled double the transfer rate, that w/ four 9GB drives represented over fifty times less capacity, and less than sixty percent of the performance of a current mid level, single drive, spinning coolly at about the spindle speed, now costing less than one-fifth of the cost of each of the old, hot running drives for a price/performance ratio of nearly 40,000:1. Those RAID arrays had to be tweaked by staggering the read/write sequencing of the heads to get those speeds.
That's impressive throughput mikebw, as the drive theoretically tops out at 170MB/sec. To pull 130 externally, solo is plenty peppy. Whatever speed increases that technology brings us, software developers are equally quick to write bloatware for it to keep the user experience in check. Imagine a SE/30 w/ a Daystar accelerator and 130MB/sec hard drive, running OS 6.0.8, or even 7.5.x :-)
Edit: Uh, oh. Good luck w/ the redux, I hope it comes back OK. I zeroed mine before putting it in the USB case, but did very little hands on testing while hooked up the Mac before the zeroing.

I have one on order. It should be delivered tomorrow. Hopefully it will work better long-term than yours.

Update 2: The drive is actually fine, no problems with the Hitachi.
It looks like this is actually an eSATA / Hackintosh issue. Can't explain why it worked at first, but the drive will not mount on eSATA now. Works 100% over USB. Also, if I startup using the iBoot disc it works fine over eSATA. I tried installing the JMicron36xeSATA.kext from within MultiBeast, but it did not help.
Trying to figure out what to try next. I just tried doing a UserDSDT install but it crashes on startup, I might have the wrong BIOS version.
EDIT: One thing I have never understood is why everything seems to work 100% using iBoot, but when you don't use that (and boot straight from your system drive) you have to mess around with finding the correct extensions for everything.

I've been trouble shooting this for a couple hours today, still no solid solution. I got the drive to mount again over eSATA after reinstalling the JMicron36xeSATA.kext and messing with a few other things, but all-in-all everything was basically back to where I started. Going to post my concerns on the tonymacx86 forums.
