-
- Not really. The fastest IEEE 1394 defined to date is 400mb/s, which is
- 50MB/s if you don't lose anything from overhead. A 16-bit Fast20 runs
- at 40MB/s.
-
- >b) much cheaper than Fast-20,
-
- Fast20 controllers aren't that much more expensive than plain old
- SCSI-2. That's basically because the technology for these rates has
- been there a long time, it was more a matter of formality to define
- the faster protocols. Similarly, drives are a little more
- expensive. Right now, an IEEE 1394 chip costs more than twice that of
- a Fast20 SCSI chip, not to mention complete boards (someone on
- comp.sys.be today was complaining that no IEEE 1394 boards are out for
- under $1000, today, even though the TI chipset costs about $80).
-
- And if the host adaptor is expensive, the drive will be too.
-
- > and c) pretty easy to use.
-
- No doubts here. SCSI was never defined as something consumers should
- be mucking around with. Fast20 is even nastier than SCSI-2, less
- forgiving to the wrong hookups, and you had better use shielded cable
- if you're going very far. In time, 1394 will cost less, IF it manages
- to catch on in the consumer market.
