This is an improved version of the popular SCSI2SD. It's smaller, less power consumption, and can be powered by the SCSI bus in some cases.

SCSI2SD emulates a SCSI-2 hard drive using a micro-SD memory card. Each SCSI2SD includes a fully assembled and tested circuit board, ready for use.

A SCSI2SD package does NOT include the followings:

  • Micro-SD memory card
  • Bracket for mounting within a 3.5" drive bay.
  • SCSI cables, power cables, usb cables, or any other accessory

Please visit the SCSI2SD page at http://www.codesrc.com/mediawiki/index.php?title=SCSI2SD, where you will find the GPL3+ software source code.

The hardware design for this new board is not currently open source.

  • Firmware updatable over USB
  • Highly configurable over USB
    • Selectable SCSI ID
    • Selectable parity support
    • Enable/disable Unit Attention Condition
    • Artificial limits on the SCSI disk size (eg. limit size to 4G to avoid OS bugs)

Added SCSI2SD to Nextstation turbo

excellent product, it took a while to configure the sd card, because next disks have a special way of configuring sectors and tracks. Working perfect

Added SCSI to an Aksi S2000

After adding a header to the main board and scsi2sd guick arrival, the unit worked out of the box, used provided tool to partition sd card and was away, now i have four scsi drives tochoose from
Much much better than old floppies or floppy emulator.

Works with default settings on Solton MS80

I put this in a Solton (Ketron) MS80 arranger which is basically the same as the MS100, just with a button accordion keyboard. You can see the Quantum Fireball on the right which it replaced (1280MB, about double the size described in the manual so possibly already a replacement). It's noisy (annoying for a musical instrument) and had become unreliable (started up only every other week, enough to get everything out eventually but nothing you would have wanted to depend on), and the arranger makes working with a "floppy" more painful than with the floppy-only arranger models.

Changing the default settings for higher speed (SCSI-2, allow disconnect) was not a good idea and led to eventual bad sectors: my guess is that the resistor networks are not good enough termination for SCSI-2 speed, at least when the ribbon cable is folded awkwardly. I put all settings back down to default and found a different mechanical arrangement: the card is now not in place of the old disk but rather piggy-backed on the Adaptec SCSI controller with two screw-in posts (the Adaptec fortunately has two screws just in the right place for that). There is no mass interface on the USB, and this arranger uses a file system of its own anyway, meaning that you cannot take out the mini-SDcard and hope to do anything in a cardreader other than backing up the whole enchilada with a low-level dump, so there is little point in trying to create a partition table (and reserve space for it) since no other device is going to make sense of the card contents anyway, and for interchange there is the "floppy disk" (a USB stick based floppy emulator in my case).

All in all I am glad to have got this. Let's one continue rely on the old gear. At least until the Eproms forget their contents...

Excellent product for replacing vintage hard drives.

After restoring two vintage computers (Macintosh LC III and DEC VAX 4000-200) I decided to replace the original hard drives that were too noisy and unreliable with a SCSI2SD card from ITEAD. Easy installation and works great. My VAX runs with this card since more than a year without any hassle. I recommend this product.
