SCSI Ancient and near obsolete Hardware!!!

[Tahoe]

Adolescent is bang on: SCSI is not obsolete; but 50/68 pin and soon 80 pin drives are.

15K SCSI drives are still very often used in servers and highperformance SAN environments. These are all bases on SAS technology; and there is no way of connecting those to your Amiga. (Serial Attached SCSI)

Higher-end drives are all Fiber Channel technology.

Computer stores (specially here in Holland) haven't been stocked well coming to SCSI; but terminators are still to be found; even the 25pin ones. But if I need one I have to look at specialist stores catering towards the server market.

iSCSI is a very interesting development. I use it at work; to fiddle around. Basically what you get is a LAN port (even interconnected with switches) directly on your SAN. If you get an iSCSI compatible network card it means a server can boot from your SAN without having ANY physical drives attached.

While SCSI might offer better single drive performance (15kprm drives), the costs of such system compared to nice SATA RAID setup makes SATA more affordable and attractive.

Agreed, specially looking at the current SATA drive prices. These have been falling really rapidly.

Don't forget the Raptor drives; these 10K RPM SATA drives offer more punch then any regular SATA disk. Although; the larger the disk; the faster the transfers (generally speaking). Specially the new perpendicular recording technology has been a boost. My Seagate 7200.10 series 500GB disks in RAID-0 are very fast, only slightly slower then my OS disks (Raptor 146GB 10K RAID-0)

I'm not denying SCSI has it's special uses, but in generic use servers SCSI has been dead for years.

Sorry, I have to disagree. Take a look at HP servers; most of them still run SCSI. The new G5 series Proliant now offer a choice of SATA or SAS backplanes; but the G4 (only EOL for about 9 months) is still 100% SCSI.

In practice SATA has replaced SCSI in many cases. This is why I consider my argument valid.

Don't forget that SCSI drives (even the new ones) are much more robust then SATA/ATA disk. We have a SAN at work which is built around very fast SCSI disks in an array and cheap; dump storage in an array of SATA disks. (best of both world so to say, 1.5TB SCSI, 7.5TB SATA)
The SATA drives fail about TWICE as much as the SCSI disks.
(if one scsi drive fails a year; at least 2 sata disks will fail)
