I can second this. We use SATA raid5 locally in our fMRI-server, continuously running without probs so far. -----Oorspronkelijk bericht----- Van: SPM (Statistical Parametric Mapping) [mailto:[log in to unmask]]Namens hao zhang Verzonden: woensdag 30 maart 2005 9:24 Aan: [log in to unmask] Onderwerp: Re: [SPM] SATA vs SCSI and local HD vs NAS Agree with Russ. I used PC/SATA under Linux while ago, felt much faster than Sun/Blade workstation. Additional to adding RAID box to your workstation, attaching a external harddisk via USB2 or Firewire port should be also a convenient option, though I never really compared there two options.
