I was advised to consider the "SCSI Hard Drive Emulator for retro computing" at http://www.codesrc.com/mediawiki/index.php?title=SCSI2SD
This looks pretty cool. SCSI-v1 in one side, and an SD card on the other.
Which version should I buy for an Apple II RAMFAST setup?
"V5: This is the stable version, with the widest compatibility. Most people should buy this version. It works well with both SCSI1 and SCSI2 systems.
V6: This board offers better performance, but is more expensive. It may not work properly in SCSI1 systems, including any system using DB25 cabling or passive terminators. It requires more power than the V5 board and may not be stable using the scsi cable terminator power alone...May not work over DB25 cables. Such systems are usually limited to 1.5MB/s SCSI transfers. Use the V5 version instead."
Just checking with the community: has anyone tried to use the V6 version?

I tried the V5 with HS-SCSI and A2-SCSI successfully. Speed is good.
The AztecMonster CF->SCSI converter is good as well.

Based on that quote, I would go with the V5. No question about it.

Does anyone know if this "SCSI HD" card would work with/on (terminating) an FCP Sider SASI chain?

With the RAMFAST SCSI utilities I created twelve, 32MB partitions, wanting to load up some of the cool partitions here: http://www.whatisthe2gs.apple2.org.za/cffa2-card-review/.
However, when I pull out the MicroSD card (8GB Sandisk) and insert it into Windows, CiderPress cannot seem to read the card. When I select "Volume Copier" and point to K:, CiderPress quickly prints "examining contents, processing xxx" for each partition and then dies a horrible modal dialog:
Assertion failed!
Program: .../diskimg5.dll
File: DiskImg.cpp
Line: 1156
Expression: fLength >= 0
Ouch! Is this a bug in CiderPress? I'm not too familiar with the program. I was assuming that CiderPress would allow me to do a mass copy of all the files in the WIT2GS site onto the partitions I created. Has anyone used CiderPress to copy entire partitions for RAMFAST? Any advice, other than entering a GITHUB bug report? I hate to do that since I'm not even sure that I'm using the program correctly. But given that it starts to analyze the K: MicroSD card and prints the partition names, it seems that it's trying to do the correct thing.
p.s. as a test, I booted the System 6.0.1 disks and was able to install GS/OS onto the first partition, named "SYSTEM." But I /do not/ want to go through the trouble of loading programs from disks! I need to download them and then write them onto the MicroSD, either entire volumes or individual files / directories.
Help...

Michael,
For reasons I can't fully explain, I've found the best compatibility
(with non Apple II computers) when using the RamFAST is to partition the
media on my Mac, rather than with the RamFAST utilities.
The RamFAST will recognize media partitioned 'elsewhere' and will work
just fine.
I realize that you're using Windows, not a Mac, but I would partition
your card in Windows first and try again.
The SCSI2SD sounds like a great device. It's on my list of things to get
for my RamFAST. I mean, how long can all my ZIP 100 drives last, anyway?

I appreciate the input. I don't own a Mac, but maybe something on Windows that would be similar?
Ouch. I think the "similar" thing is CiderPress, and it's throwing an assertion. If I could get a couple people to tell me that I'm not doing anything crazy, that trying to open a volume on a MicroSD card /should/ work, then I'd put in a bug report to CiderPress. I suspect that it /should/ work because it lists every volume on the SD card in quick succession before it blows the assertion error. I'll wait to see what anyone else says.

As far as I know, CiderPress can not read Prodos formatted disks directly. Your SD card would have to be formatted to either FAT32, NTFS or HFS or HFS extended, then a 32 MB .2mg file on that SD card can be read by CiderPress.
Also a note, you don't say if you are using the RAMFAST in a IIGS, but I uploaded an HFS 700 Mb cd image (compressed to a 650 kb .zip file) in the .iso format that CiderPress can read. With a SCSI cd player plugged into the RAMFAST, you can read the cd using GSOS.

I would think that for CiderPress (on a Windows PC) to read the disk images on your SD card (It should be a formatted: FAT {16-bit}!), you would have to put (empty/populated) disk images on the card, created [by CiderPress {or another process (see below)}] on a PC.
Examples of disk image templates created with CiderPress (by me):
CiderPress-0. Apple-II {113.75 KB} 5.25'' Floppy Disk.D13
CiderPress-1. Apple-II {140.00 KB} 5.25'' Floppy Disk.DO
CiderPress-2. Apple-II {140.00 KB} 5.25'' Floppy Disk.DO
CiderPress-3. Apple-II {140.00 KB} 5.25'' Floppy Disk.PO
CiderPress-4. Apple-II {800.00 KB} 3.50'' Floppy Disk.PO
CiderPress-5. Apple-II {1.41 MB} 3.50'' PC Floppy Disk.PO
CiderPress-6. Apple-II {5.00 MB} HDD.PO
CiderPress-7. Apple-II {16.00 MB} HDD.PO
CiderPress-8. Apple-II {20.00 MB} HDD.PO
CiderPress-9. Apple-II {32.00 MB} HDD.PO
CiderPress-10. Apple-II Pascal {140.00 KB} 5.25'' Floppy Disk.DO
CiderPress-11. Apple-II Pascal {140.00 KB} 5.25'' Floppy Disk.PO
CiderPress-12. Apple-II Pascal {800.00 KB} 3.50'' Floppy Disk.PO
You can also make disk images with Apple Commander, that CiderPress can access.
You can also download empty disk images of various sizes that CiderPress can access. I don't know if the dynamic (11KB~32MB) HDD disk images will work for you (on your Apple II), but CicerPress can access them also.

After some reading, I'm convinced that assertion failure is a CiderPress bug. I'll enter a bug report. The entire point of CiderPress is to access non-MSDOS volumes, like the SCSI hard drive I dragged over to my Windows machine (albeit sitting on a MicroSD card, no doubt not an uncommon activity.
From http://a2ciderpress.com/features.htm#physical:
"Direct Access to Physical Devices
With CiderPress you can directly access physical devices on your PC. For example:
...
...
Read and write files on every partition of an Apple II hard drive. Got an external SCSI drive connected to your //gs? Plug it into a SCSI card on a PC and open it."

Further information: when CiderPress throws the assetion, you can click [ignore], in which case it lists every RAMFAST (ProDOS) partition and allows for [Copy to File]. I did a copy to file of my SYSTEM partition where I loaded GS/OS 6.0.1 (manually) and CiderPress created a *.po for me. Using CiderPress, again, you can load the *.po and witness all of the GS/OS files.
CiderPress recognizes the file system as it should, according to its documentation (and according to its raison d'etre). There's a simple bug in the code, I'm quite sure.
Unfortunately, in that dialog, [Load from File] is greyed out. This puts the kibosh on my reason for using CiderPress: to load partitions already created and populated at http://www.whatisthe2gs.apple2.org.za/cffa2-card-review/. Perhaps the greying-out is related to the assertion failure.
I've registered this as a bug and I'm very hopeful that it can be rectifed.

Well, that blows my mind. I have 4 Prodos partitions and one HFS partition..
All the files show up for the Prodos partitions but do not show up for the HFS.
Which is ok for me as I have 6000 files on the HFS volume that I particularly wouldn't want displayed.
BUT! It looks like you can do a COPY to and from the HFS partition. You first need an HFS disk image that has the files, then select the Volume copy icon and then the image to copy from.
This should be able to copy to your SCSI drive.

I didn't really test that further, but you may not even need a HFS image to copy from.

A couple of hours later, I just realized I kept saying HFS. I have been relating SCSI hard drives to HFS format due to me not having a SCSI card for my Apple and use these hard drives on my old Macs.
I just meant to check the copy volumes to see if your SCSI hard drive shows up, you may be able to copy files that way.

Status Update:
I've entered a bug report to Mr. McFadden. Whatever the problem is, it seems to be a small oversight, perhaps something not encountered yet, resulting in a code path that falls through to the assertion.
Overview: my "SCSI hard drive" is a MicroSD card using the SCSI2SD card mentioned in the 2nd post. The RAMFAST in slot 7 (latest firmware) connects to a gutted 20SC drive enclosure holding the SCSI2SD and the cheap, 8GB card that they sell to go with it. This seems to work really well. I created twelve, 32MB partitions and then manually loaded GS/OS 6.0.1 to the first 'SYSTEM' partition. This looks like a fantastic solution, if you want to play with SCSI.
Now, when you remove the MicroSD card and hand it to Windows, Windows will ask if you'd like to format it since it doesn't recognize the file system. The answer, obviously, is, "no." When you run CiderPress, those operations that work on volumes correctly list the MicroSD drive, in my case, K:.
When you attempt to use K: to operate on one of the SCSI partitions, the "fLength >= 0" assertion triggers. You can [IGNORE] it and CiderPress continues and correctly lists the ProDOS partitions. A little bit of user error, here: the [Copy from File] operation (load the partition from a *.po) is greyed out unless you uncheck the [x] read-only checkbox. Oops. At this point, you can [Copy to File] and save each partition to a *.po file. It works beautifully...I think. I haven't had much chance to load and save, back and forth, yet, but I'd bet the farm that CiderPress is working correctly.
If you copy the first [MacPartition], you'll get an 8GB file. That first partition represents the entire MicroSD card.
The remainder of your partitions are listed and each can be saved to disk as a *.po. I presume that I can also load them up by reading a *.po. I'll play with that later today. Since that's the functionality I needed, then "job well done."
If you attempt to copy the last partition, the unused space, another assertion will be thrown: DiskImg.cpp, Line 2371, Expression: false. Mr. McFadden has been made aware of that one, as well, and no doubt will see to it. My guess is that the code path is falling off the end of some if-elseif's and not setting a variable correctly. My gut tells me that it will be fixed very quickly.
I'd like to point out that CiderPress is fantastic. I haven't used it for several years since my Apple obsession was sidelined for a while. And Mr. McFadden is the very definition of Johnny-on-the-spot, and a courteous one, too. My bug report was immediately looked at and responded to. Coming from a software background (25+ years as a programmer), I really appreciate his efforts.

The RAMFAST in slot 7 (latest firmware) connects to a gutted 20SC drive enclosure holding the SCSI2SD and the cheap, 8GB card that they sell to go with it. This seems to work really well. I created twelve, 32MB partitions and then manually loaded GS/OS 6.0.1 to the first 'SYSTEM' partition. This looks like a fantastic solution, if you want to play with SCSI.

A little bit of user error, here: the [Copy from File] operation (load the partition from a *.po) is greyed out unless you uncheck the [x] read-only checkbox. Oops. At this point, you can [Copy to File] and save each partition to a *.po file. It works beautifully...I think.

As suggested in one of the posts, if you format/partition the disk with an older Mac (or if you have one of the other Apple-branded SCSI cards and corresponding utilities), the generated Apple partition table might be more compatible with utilities like CiderPress. I remember that the partition table created by the RAMFAST utilities had some oddities with regards to the partition table specs.
In contrast to some other posts, your SD card will not be formatted as FAT/FAT32 when used this way. It will be a standard block device, with an Apple partition table, and the partitions can be formatted with the ProDos file system. CiderPress is able to read such a standard block device with ProDos partitions -- which is Drive K: in your case. The reverse is not true though -- CiderPress currently *cannot* create a multi-partition disk image that can be copied block by block to a device using something like 'dd' (the capability is in the list of feature requests).
You probably can use Apple Commander to create a multi-partition disk image to match the size of your SD card. I think this creates a more compatible partition table. Then 'dd' that disk image to your K: drive, and then use CiderPress to mount the K: drive and read/write files into the ProDos partitions.

This version corrects a math overflow problem that was triggering the assertion.
In a nutshell: if you have a RAMFAST, go get a SCSI2SD. It's great! It even has two prongs for an external LED. I took out my big hard drive, mounted the SCSI2SD card (using the mounting bracket that they offer for sale), and simply unplugged the LED from the hard drive and plugged into the SCSI2SD card. Putting the lid back on, the 20SC looks like a fully-functional, old-style Apple hard drive.
There is one exception to this setup, though: the 20SC is not plugged into the wall. You don't need to power the SCSI2SD card; I guess it pulls +5 volts off the SCSI cable.

Where did you purchase your SCSI2SD card? What company? What website? For how much?

I also vouch for the usefulness of the SCSI2SD solution. I've been using it in my IIgs (with the Apple High Speed SCSI Card) since it was v3 and had to buy it from Australia, and also have upgraded to the smaller v5 hardware.. The v3 will probably go into other SCSI-based retro hardware that I play with.
