- RE: Looking for good read/write optical drive
-
- I am also looking into optical 128MB drives. I can add some salesy
- information to the discussion.
-
- Pinnacle Micro, 800/553-7070
- model PMO-130
- list $1995, dealers are offering for around $1500
- Claim 19ms access on what they call a 1/3 stroke test standard to the
- optical industry - note this is NOT the same test hard drive manufactures
- use. WIth the 4MB cache, read/write transfer rate is 1.4MB. With out the
- cache, read/write averages 360K. The PMO-130 was released before the 11-92
- MacWorld optical disk review. The PMO-650 which shares software and cache
- technology was the recommended buy for 650MB drives.
- NOTE: the split optics and mechanism of the PMO-650 are NOT used in the
- PMO-130. This is from one of their sales persons, even when I called him
- on the fact that the sales literature specifically says it has "split
- optic design". Even so, the numbers given for the PMO-130 are exactly the
- same as the PPMO-650.
-
- MacDirect, 800/621-8461
- sold directly, NuDesign MOST $1298, NuDesign Epson $1188
- The MOST mechanism drive was in the MacWorld review, it was one of the two
- recommended 128MB drives. The MOST is said to have 30ms average access
- time, the Epson 38ms. The salesperson could not specify the test used for
- either model. Transfer rate is 512KB/sec and 768KB/sec for MOST and Epson
- respectively. The spindle speeds are 2400 and 3600 in the same order. Both
- have 256KB cache.
-
- MacProducts, 800/622-3475
- Magic 128 Turbo
- sold directly, $1199
- The earlier model (Magic 128) was the other MacWorld recommended buy. The
- new model is the same Epson 3600 rev/minute mechanism as the NuDesign
- Epson listed above. Again, salesperson had only an Epson data sheet
- and could tell me what kind of test were used to derive access and
- transfer rate specs.
-
- Errata:
- The MacProducts salesperson said the drive could NOT be a start-up
- device. PMO's guy said theirs could, I forgot to ask MacDirect.
-
- The PMO-130 has been shipping for less then 2 weeks.
-
- All said drives come with cable and cdev/init, disk ejection is via trash
- can.
