- Jasmine: They report that their 20 meg reads writes at about 120 & seeks
- at 27, and that their 80 meg (only $1380!) reads writes at about 280 &
- seks at 17. I was unable to test these figures myself. Their spec sheet
- shows the 80 meg with much faster data transfer and access times than the
- 20, but they claim they had to slow it down to match the Mac. Sounds like
- a lame story to me.

- All of this stuff doesn't mean that much, because switching from a 10 meg
- Tecmar MacDrive on the serial port to a 40 meg SCSI Dataframe has only
- slightly increased the perceived performance of my system (but it feels
- great to have 26 meg of Lebensrelm left on my hard disk). Admittedly I
- turned off the cache when I switched drives (everyone seems to distrust
- the Apple cache), so the Dataframe speed is more than compensating for the
- loss of the cache.

- I though the BMUG test concluded that Sony was best, Maxell marginally
- worse, everything else not worth the failure rate and Memorex the absolute
- pits (you'd be safer and better off retyping mega-Ks of machine code from
- paper output). Come to think of it, this test is at least 1.75 years old
- and Brown diskettes were not evaluate. Never mind...
