Sure? I thought not, seeing the size of the 44 pins in the card
Pretty sure mate.
Check a normal 2.5" HD

...plus the screw holes under your SSD are the standard holes for mounting them.
As for speed...
I have never seen in my Amigas a speed test over 9.3MB/s and that's with BPPC's SCSI --> IDE via an ACard Bridge. HD is an 16GB CF.
Ofc with an UWSCSI HD on a Cyberstorm you could get a better performance... but NOTHING more than you can get with these SSDs.
For A1200's native IDE... I wouldn't expect something more than 2-3MB/s (without FastATA or Idefix Express) but even with the fastest IDE = (theoretically) FastATA.... I would be very surprised if you would succeed in achieving the MAX transfer rate at a PIO5 mode by using this SSD!
