Introduction

We tested the Intel 600p 128 GiB SSD, that uses M.2 form factor, PCI Express 3.0 x4 interface, and NVMe protocol. While 2.5″ SSDs are still the most popular ones, M.2 form factor is becoming more common. The main reason is that M.2 format allows, besides the SATA-600 connection, the PCI Express x4 standard, which has a far higher maximum transfer rate.

There is also a difference related to the protocol: while traditional SSDs use the AHCI (Advanced Host Controller Interface), which was developed for mechanical hard disk drives, the most recent drives, like the Intel 600p and the Samsung 960 EVO, use the NVMe (Non-Volatile Memory express) protocol, which was developed for SSDs, thus allowing higher speeds and lower latencies.

The Intel 600p SSD is different from most of the drives we already tested: besides using the NVMe protocol like some high performance SSDs, it is an entry SSD, being not significantly more expensive than entry SSDs with similar capacity like the WD Green, the Corsair Force LE, the Kingston SSDNow UV400, and the SanDisk SSD Plus.

Just like most new SSDs, the Intel 600p uses TLC (triple level cell) memories. This kind of memory stores not two, but three bits per cell. It allows a higher data density and, thus, a smaller manufacturing cost for a same capacity chip.

In the table below, we compared the tested units. Except for the 600p, all of them use SATA-600 interface and the 2.5” form factor, with 7 mm height.
