Hi! I am looking into magneto-optical (MO) drives and would like to hear some feedback on them…especially when used for daily data retrieval instead of just backups. (Essentially, I am running out of hard disk space on my portable – it's already STACked – and am exploring ways to augment my storage. SCSI-2 would be the perferable interface, since my portable already has a built-in port. I would primarily use a magneto-optical drive to create and store projects from 3D Studio and Ventura Publisher. What are the advantages/disadvantages of the 3.5 vs. 5.25 MO drives? (I understand that 3.5 drives hold 128 MB while the 5.25 holds 600 MB (300 MB/side) – but that the 5.25's are signifcantly slower than the smaller format). What manufacturers/models would you recommend? I have seen ads for drives by Pinnacle Micro, Sony, Peripheral Land, Procom Technology, MicroNet Technology, and Mass Optical Storage Technologies (MOST). MOST claims to have a "free form" mode that stores 256 MB on a 3.5 MO disk, but what is "free form" and what does this proprietary method mean for compatibility? Can MO drives be STACKED? STAC Electronics thinks they can, but doesn't seem to know for sure. And finally, what other issues or technologies should I consider? Again, my primary aim is additional secondary storage… I am attracted to MO since it seems to offer both reliable backup and "unlimited" secondary storage – all through a SCSI-2 port. Thanks in advance! Ceyan

There is a standard ANSI/ISO for the 128 meg magnetic optical drives so they are supposedly compatible between everyone. The drive is around $2000 and the carts (128meg) are similar in price to Syquest carts … (by the way IBM and a group of 9 vendors came up with the ANSI/ISO standard to try to unseat syquest as the king of removable media). The speed is supposed to be under 30ms and I have heard claims to 9ms. The other formats 600 meg drives have little or no standards I guess their is a sony standard somewhat. But interchange between these drives is very questionable.

Albert, Thanks – I didn't know that the 600 meg carts didn't follow a standard… I guess that's another reason to go with the 3.5" drives. Thanks. Ceyan

meg drives have little or no standards I guess their is There is an ISO standard for the 600meg MO drives and currently all 5 1/4" MO vendors support it. Best Regards, Arnold Jones Micro Design

Thats nice to know that some standard exits.

Two suggestions! Low End = Bernoulli 90mb Transportable. Great interfaces, MAC SCSI, PC SCSI, and Parallel. Cheap and fast enough as an added drive. High End = Storage Dimensions 1gb Read-Write Optical Disk Drive, 500mb each side. Works great if you can afford it.

I love the hi-end 1 gig carts!
