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.
