Analyzing the data obtained on our tests, the first conclusion is that the Intel 600p 128 GiB has the same performance with compressible and uncompressible data, which means its controller does not use compression to speed up operations.
Compared to its competitors, we were expecting the 600p would be a lot faster on many tests, because PCI Express 3.0 x4 used by it supports a far higher bandwidth than the SATA-600 interface used by the other drives. It also uses NVMe protocol, which is usually found on high-performance SSDs.
However, we saw a performance that was faster only on the sequential read and random read with 512 kiB blocks. On the other tests, it performed similarly to most of the tested drives.
So, we can say the Intel 600p 128 GiB SSD presented a cost/benefit ratio that was similar to most SSDs of the same capacity: it costs a little more, and it is a little faster on some tasks. However, it has two advantages: the M.2 form factor, which is easier to install and avoids more cables inside the computer, and also its endurance (measured by its TBW) that is higher than the other tested models.
