#How many GIG's per minut
IBM is making a new series of drives both a 5 gig and a 8.7 gig 3.5" form
factor that are rated AV and will deliver above 5 megs sustained throughput.
The Seafgate Elites will not do this and as far as I know, there is no drive on
the market yet that has broken the 5 meg barrier.
I'm testing 4 IBM Ultarstar XPs that are the forerunners of the new IBM AV
drives. They spin at 7200 RPM and are actually faster than the AV dirves IBM
will produce. I get a minimum op 5.2 megs per second sustained date
throughput, 6.5 – 7.0 most of the time. The Flyer needs 5.0 megs sustained to
record lossless MII or Betacam SP on all shots. It needs less for a
closeup/medium shot etc since there is less detail. The quality is the
equivalent of other systems that use arrayed drives to get 4 to 1 JPEG
compression rates if you use Flyer HQ5 continuously as I do.
The IBM drives will be released this summer and faster drives are on the
horizon. Flyer D2 lossless needs 8 megs sustained throughput. These drives
probably won't surface until next year, but the Flyer is processing at that
res. Problem is now you can't record or play it back so D2 will not be a
reality unless Newtek can figure a way to use arrayed drives. If you arrayed
two of these IBMs you could get well ove 10 megs sustained throughput which
would utilize Flyer D2 capapbilities.
I must say that having these drives greatly enhance the utility of the Flyer as
you can lay down exactly what you put in (to the eye at least, and for the
veiwer what else matters?). These type of drives will probablly sell for $1750
wholesale for the 5 gig form factor and I'm getting about about 21 minutes on
each drive in HQ5 mode.
I must reiterate my previous post that I wish to hell people would stop blaming
Newtek for laggardly drive technology. IBM has told me these fast drives are
overkill for 99% of their market so they have not been motivated to make them.
Hence we're victims of supply and demand, not Newtek's folly.
