- I've owned a Bernoulli 90MB for about 3 weeks. It's attached to
- an otherwise stock A3000/25. So far, it works great.
-
- Before I purchased I called Iomega and they told me that the double
- drive (that is VERY common here at the Lab) wouldn't work due to SCSI
- addressing conflicts and to get the transportable single version.
- They told me to look for a Mac version, because it needs a 25 to 15
- pin cable that the Mac also requires. I scanned
- the Mac rags and saw that they have two varieties: the regular
- transportable (about $680US) and the "Mac transportable" (about $500),
- the difference being that the latter is internally SCSI terminated
- so it has to be end of the SCSI daisy chain. No problem - I bought
- the Mac transportable.
-
- You tell me if it's cost efficient: the drive with one 90MB cartridge
- is $500 and a set of 3 cartridges goes for about $425, so for $925
- I have about 340MB (formatted) of extra storage. AmigaMan (not an
- endorsement) is advertising Maxtor 213MB SCSI disks for $550US. Where
- the Bernoulli starts to pay for itself is as I begin to add more
- cartridges at $125/MB. AmigaMan has the 120MB Maxtor for $379.
-
- Another consideration which I haven't tried: I asked c.s.a.hardware
- about using the Bernoulli to read PC format disks via CrossDos. Several
- responders told me it was possible.
-
- I chose the unit for several reasons, which may not apply to you:
- 1) Applications: I run Imagine and am tired of having to delete
- last week's renders to fit this week's on.
- 2) Backup of my 100MB hard disk; most of the disk is junk and s/w
- installations. The important stuff would fit on a handful of
- floppies, but I like the idea of getting entire directories with
- all software installed in one shot.
- 3) Compatability with the PCs at the office.
-
- My biggest complaint is how loud the drive is. The unit stops spinning
- (I think) when not busy, but the fan is very loud, a continuous drone.
- I also don't like how the Amiga won't boot until it sees the Bernoulli
- powered up *with* a cartridge plugged in. Then it comes up and doesn't
- see the drive after all. I've played with the mountlist a little to
- no avail; if anyone has solved this, I'd appreciate a copy of your
- mountlist.
-
- However, I really like how easy it is to hook up to the A3000; there's no
- additional system software required. Because it's a Mac unit (even says
- "Mac Transportable" on the front), the included disk comes loaded with
- a bunch of Mac PD software. I formatted it without scanning it, but
- if you have a Mac handy perhaps there's something usefull there. The
- HDToolBox is easy to prepare the cartridges with - you can use it to
- ask the drive it's architecture (number of heads, highest cylinder, etc).
- Don't forget to do an AmigaDOS "format" on the unit once you're finished
- with HDToolBox (a recent post reported this).
-
- As far as speed, I loaded a 12 frame 24-bit animation using Imagine from
- the Bernoulli. It took about 15 seconds. I loaded the same animation
- from the harddrive and it took about 13 seconds. Very course timing
- withstanding, the difference in speed is acceptable to me. If I
- were doing an I/O intensive application, I would place it's data files
- on the harddisk.
-
- The solution works for me; your mileage will vary.
