I have to check the release date but, in the mean time i got 10 of them, i was using DGVS 9ZX/10K and Seagate 18G/10K and that was another music... (However, i found seagate far to be reliable). I'm now building an experimental machine with 12x18G Ultrastar2 (with 4MB cache) and ccd. Honestly, DCAS and DDRS series are suffering from slow SCSI processing and poor tagged-qeueing. Softupdate and Write-cacheing helps a lot (I know. I wouldn't be using WC with SoftUpdates). PS: I also updated Adaptec BIOS to 1.34.2 on a machine that periodically crashed and problems disapeared. I do not understand why since i always believed that the aic driver takes full control of the card. Can someone explain ?
