Message-ID: <22452@uflorida.cis.ufl.EDU> Date: 26 Feb 90 01:01:36 GMT Sender: news@uflorida.cis.ufl.EDU Reply-To: jma@beach.cis.ufl.edu (John 'Vlad' Adams) Organization: UF CIS Department Lines: 41 I recently received my A2000HD with the Quantum hard drive. I've been relatively happy with the setup (except for needing to populate the two meg space on the A2091.) However, I am not happy with the results of DiskSpeed 3.0. Friends of mine running Kronos 16bit non-DMA cards with Segate 28ms drives are reporting faster rates. Shouldn't a DMA card with a 19ms drive perform much better? Oh, the background processes running concurrently with this run are: ConMan, QMouse, Handshake, NoClick, Bypass_ARP_fr, and Bridgeboard [Atime, Amouse, PCDisk.] I've run the test with none of the above and the results weren't much better. (At best a few 10k bytes/sec increase -- but not an accurate reflection of my normal environment anyways.) The Quantum is rated at 2.0 megabytes/second asynchronious transfer rate in addition to having a 64k cache. So I doubt the drive slows the performance. So is this standard? Has Commodore limited a speed demon? Here is the output from Diskspeed 3.0.
