USB 2.0 Enclosure - Question about UDMA33, ATA-66 Standards
Posted: Sat Jan 11, 2003 1:58 pm
I'm a cd-r newbie and recently purchased the Buslink (Liteon) 52X24X52 internal burner that I'm planning to install in a USB 2.0 external case. I didn't really like any of the existing external burners on the market and thought that this would give me the flexibility to swap in/out any IDE drive that I wanted in the future. I've been looking at various enclosures with the kind assistance of others in this group (Ian, BuddhaTB, etc.) and have narrowed my choices down to 3 models that are all for sale on this website:

The ADS USBX-804 model says that it supports UDMA 33,66 or 100 and I understand that UDMA 33 is the standard that most burners use today. The Speedzter5 and the "All Aluminum Constructed" case say that they suppport ATA-66 and 100. I'm assuming that this is the same thing as "UDMA" 66, 100, but given my lack of knowledge of the terminology, I'm just not sure. In addition, these models do not specifically say that they support UDMA 33. Again, I would assume that if they do support UDMA 66 and 100, they would also support UDMA 33 because I thought I understood that UDMA 66 and 100 were simply faster UDMA modes, but I don't know for sure. Can anyone help assure me of this please? I just don't want to buy a case and then find that it is not the best choice for my drive.
Assuming that there are no problems with the standards supported, I like the Generic Aluminum case and the Speedzter5 as they both have cases that are made of aluminum and are also $30 less than the ADS version which has a case that is largely made of plastic. All have cooling fans as well. If anyone sees anything in the features that I may be missing that would make one case better than the other, I'd greatly appreciate any comments and input.
Finally, the ADS case says that it will do sustained data transfers of at least 35MBps, but the other cases do not have a rating for "sustained data transfers", only the theoretical "maximum data transfers" which are 60MBps under USB 2.0. Does this matter and is this something you would be worried about for CD-R burning which should only take about two and a half minutes anyway per cd with this burner?
Sorry for the very basic questions and thank you in advance for your assistance.
