Well, I've installed and begun using one of my new Samsung 870 EVO 250GBs, and things are getting curiouser and curiouser: like the first one, this one is recognized correctly and called genuine by the Samsung Magician software, but this one is called a Hitachi Hajaan SSD by Speccy and by Device manager. I have no idea what's going on here.
[Side note]: I had a Kingston 250GB as main disk and an old Sandisk 120GB as second disk on that machine. I used MR to clone the main disk to the new Samsung, then installed the new one and moved the Kingston to the second drive slot after I cloned the Sandisk to the Kingston. We're always commenting about how you'll see a marked difference in speed if you replace HDDs with SSDs, but for most uses, that speed increase is not as marked as it is when you use the disks for significant, time-consuming tasks. In my case, with the Kingston-Sandisk configuration, MR consistently took about 7.5 minutes to make an image of the Kingston disk to the Sandisk disk. The first thing I did after I swapped these disks in and made sure the computer booted properly and the drives were labelled properly was run MR to image the new Samsung to the Kingston. Three (3) minutes flat! Now *that's* a difference you can see!
So I'm happy with my new disk, but I don't understand why it's being called a Hajaan.
