What are the recommendations for brand or type of hardware write blocker?

Write blockers are used by digital preservation practitioners to ensure the integrity of digital content on a hard drive, by ensuring that nothing is written to the drive accidentally as part of processing (for example, to process hard drives received as part of a manuscript collection).

For the last few years we have been using a Tableau SATA/IDE/SAS/USB/FireWire Forensic Bridge that is internally mounting into a 5.25 inch half height drive bay on an acquisition computer in our forensics lab.

For floppy disks, we have been a Kryoflux on two different acquisition computers in our forensics lab. Kryoflux is hardware plus software.

In addition, we have had a Digital Intelligence UltraKit portable kit (crazy bright yellow) which contains a number of different hardware write blockers and adapters and connectors for use with all sorts of hard drives or storage devices.

I've found that forensicswiki.org is a great site just for finding out what's available: http://forensicswiki.org/wiki/Write_Blockers.
