The SSD part is too small from my point of view. The drive is really fast when working on a project for which all fits into the 8GB SSD memory my drive has. It becomes a totally different story when compiling the kernel or installing large ports. Even a simple 'exit' from a shell can take a minute when the shell I want to return was moved to the swap partition. Yes, this one minute is sixty seconds. The same is true when writing large amounts of data to the drive. The drive becomes slow, very, very slow. When the data to be read are not in the SSD part, the drive behaves like a normal HD when you are not writing large data sets at the same moment of time. This is also my second drive. The first one died after less than 15TB of data had been transferred. Of course, Seagate exchanged it for free. Both drives showed the same behaviour. With other words, it is a double sided sword.
