I have some of those, but I prefer the ones with 68 pin interface instead of 50 pin SCSI.

I don't understand the prices of these ACARDs. Couldn't you just buy a used SCSI HDD for a lot less?

They are ATAPI ONLY (that model anyway) so hard drives are not supported. The adapter lets you use a more modern IDE based tape, removable media, or optical drive on an old SCSI bus.

I like SCSI myself, but when you're at the point replacing the SCSI drives with an IDE drive, Compact Flash or SD Card on a SCSI adapter you should rather get a PCI SATA controller and a SSD if your computer got free PCI slots (not including computers that aren't PC compatible).

Emphasis added.
Yes that's one of the main uses for these adapters that live on the bus instead of slots. Hardware compatibility, lack of drivers etc. I for one would love to add a Promise ATA or SATA adapter to my AlphaPC which even has PCI slots. But without driver support, and more importantly without BIOS support that would be useless. Therefore bus adapters.

For Dos, Mac and Amiga systems, then go for one of those SD-to-SCSI adaptors. Much cheaper.

Sorry, which ones are you talking about?

Thanks

Just google SD2SCSI. Thay are all over the place. 56 to 75 US Dollars vs. 1000 US Dollars are kind of a price difference.

No it's SCSI2SD.

There was a pile of these at VCFSE for something like $50-60. I passed on it because I thought that was a little high for what it does...

For me, it allowed the revival of an Alpha system without any fuss. Replaces 1 CDROM and 3 HDDs, all SCSI. Working on setting up a multi-boot NT4/W2k/Linux all on a SD card.

Anyone going to benchmark the $98 SCSI2SD, the one that runs up to 10 MB/s, against a standard 50-pin narrow drive?

I'll do it if you pay for it. 😀

I'll do it if I pay for it too!

Maybe if the 5.25" mounting enclose was included in the price, and there was free shipping, I'd buy one.

Unfortunately, the SCSI2SD is only limited to 5 MB/sec, 10 MB/sec max. the pricey version, which defeats the whole point of wanting to feel the thrill of a PCI ~120 MB/sec wide SCSI (let's say 80 MB/sec) controller hooked to an advanced fast (UDMA7) CF Card (about same read and write tested net speed) via the SCSI to IDE adapter!

But thanks for the useful info you provided, much appreciated 😊

Maybe now Intel/Altera are trying to make FPGA units more affordable, someday you can have an SCSI2CF or a SCSI2ATA in the price range of the SCSI2SD. Before wasn't possible without using a separated mid level CPLD or an FPGA (for the extra GPIO pins need for CF/ATA controller block/interface), adding an extra cost to the build.

Lets see how the Intel FPGA "arduino" goes.
