Your "hdparm -Tt" experiments will not be the same every time you do it,I had around 1-2 MB/sec in both reads. But even 30 MB/sec should be far enough to get dropout-free recording. 44100 * 16 * 2 (bit/sec) = 1411200 bit/s 44100*16*2/8 = 176400 byte/s = around 200 kB/sec. See? Even if you play at the same time (duplex), your 30 MB/sec is far more than that. One more thing, but be aware, I heard switching the dma-transfer-rate might be dangerous if you don't have the new 80pin cables. (right?) you might want to check. "hdparm -i" which gives you some "*" on the options that are set. see the "dma1 dma2 dma3 dma4 dma5" line, which (in my case has the "*" at the dma4=100MB/secautomatically set.) I once tried with changing that value around, but I believe you need a 80pin cable to set anything higher than dma2 = 33 MB/sec see e.g.: http://www.intel.com/support/graphics/linux/udma.htm. for the settings you might want to try out. But in anycase. I don't think it's the bandwidth onto/off your harddrive. cheers, tobias. > > According to the article, I have the _exact_ Ultra ATA/133 PCI Adapter Card _and_ Hard Drive to acheive the highest speeds.
