This is written by a non-tech person but a very, very happy one.I had a LaCie external hard drive from several years ago. It was not as thick and certainly lighter in weight but it worked well and never faltered. Unfortunately, earlier this year my2017 MacBook Pro, which had been making threatening moves for quite a while, finally bit the dust. My tech guy came out to set up the new one and wanted to use the old LaCie to install the folders and documents. Alas, I had evidently put a password on it and despite knowing the "hint" could not figure out the password from the hint. Result: Couldn't get into it and eventually had to toss it in our tech dump.I was rather horrified at the price for this so I ended up buying one for about half the price. Mistake. So a few days ago, I got sufficiently annoyed to say "the heck with it" and bought this new LaCie.It arrived today, and at first I was astounded at the weight. But I immediately plugged it into my new MacBook Pro and it went right to work, soaking up all the documents and folders I have. I thought it would take it a couple of hours but within about 15 minutes (or less) it was completely done. I don't have photos or movies or music so that would account for some of the speed but I was thrilled to now have a solid back-up (with no password as it never leaves the house) of all my work. It works flawlessly and breathtakingly fast. I could not be happier.Is it worth the price? Absolutely, positively yes! Highly recommended. (I plan to buy a second one before the end of the year; it's that good.)
