I have one of these that I bought brand new. I think I still have the original box somewhere. Mine is the low end 850 MB model. I've still got all four feet somehow, too! I believe I got mine in about 1997 or 1998. Maybe as early as 1996? 1997 seems about right. As others mentioned, it did come with LaCie software and LaCie branded paperwork in the box.
Mine was originally bought when I was running out of space on my 160 MB drive in my Performa 550. I thought it matched it nicely. When the 550 was replaced it was repurposed for work with Macs I was preparing for sale. Made it easy to boot Macs from school surplus and such and put new System Folders and such on them. I'd just have a 7.1, 7.5.5, 7.6.1, and 8.1 folder set up the way I liked and I'd drag and drop. It is still occasionally used exactly this way today, although not nearly as often.
I like my external 850 MB Apple drive. I also like that the feet can be put on so that it can be run horizontally or vertically. I seem to recall some warning in the manual about not running it vertically without the feet to avoid blocking the lower vents. I could be making stuff up, and they may have been overly cautious if this was an actual warning.
The only other external Apple branded hard drive I have I own is a HD20 SC that came with a Mac Plus years ago.
