Well now you've got me scratching my head. The SEIV is a Fast & Wide card, isn't it? As far as I know there's no Ultra-SCSI card for NuBus Macs. Theoretical maximum on a F&W bus is 20 MB/s. So I'm sitting here slack jawed trying to figure out how you got 30 MB/s out of a 20 MB/s maximum speed bus. :-) Is there a detail missing here? Two SEIVs in the same machine perhaps?
The jury is still out here. I can't work out from my extensive googling what it is but there seem to be a majority of people flagging it as Ultra-Wide. I certainly thought it was. And I did get more than 20MB/s off it.
Getting more than 20 MB/s is convincing. I would not rely on polling of folks or sites on the internet though. However, if you know the people/source in question, that's a different matter.
The reason I would not rely on polling is that there are an awful lot of people out there who apparently never heard of Fast & Wide. So when they think they need to preface 'Wide' with some other SCSI words, they *always* say 'ultrawide' even when it isn't. For example, some years ago OWC was selling the ST15150 as a Ultra-SCSI drive or Ultra-Wide SCSI drive (depending on whether it was an N or W) but the ST15150 was never Ultra.
