The HD has "reserved space" for system files, hardware configuration, mapping, directory and file indexes, etc. So your computer is probably reporting the new drive's "usable space".
Just my two shekels.

With 1.81 tb of usable space I don't think I'll ever fill it, ...
...when I started my first job as programmer, our 'big' development system (where we did all our editing and compiling) sported a whopping 5Mb hard drive.
The first hard drive I ever saw was a whopping 10Mb Western Digital unit housed in a toaster sized plastic enclosure with a clear acrylic lid so you could watch it work. That drive was dedicated to an early industrial vision system. Unfortunately, the processors took way too long to evaluate the image so it was never more than a lab toy.
It depends on your laptop's interface. The SSD in that photo will have a serial plug. Old laptops might have parallel plugs that would be incompatible. If your laptop is fairly new, it might take an M.2 drive. Those can be several times faster than the WD blue drive.Will this replace the drive in my Toshiba laptop? Also, can a SSD be partitioned the same as standard drive?
