Kingston Predator.
South Korean company Samsung may be currently playing a leadership role in the second generation of Solid State drives “SSD” that by far exceeds the previous generation speed but it seems that they are now facing some competition from Kingston specialized in memory chip development.
Kingston, the US company has introduced the “HyperX Predator” card with reading speed of 1.4 GB/second, although this is much lower than the reading speed provided by Samsung MS-951 SSD.
But those thin Samsung  drives go to OEM manufacturers such as Lenovo, Sony and Dell, which are required for ultra-book ultra-slim laptops that dose not fit the current design of the SSD 2.5-inch in addition to the “GSM 951” that use “PCI Express” port and not the standard SATA3.
On the other hand, you can actually buy the “Predator” drive and install it in your personal computer that you build or even on your laptop, and everything you need for this is an appropriate slot of  “M 2 SSD” but if it is not available, Kingston provides and adapter that you can buy for a few extra dollars.
The write speed of the new Kingston drive is 1 GB/second, while the random read/write speed (IOPS) is up to 130000/118000, but get this speed does not come cheaply, because the price of 480 GB of this model is $460, It is almost twice the price of standard SATA3 “Hyper X” 480 GB.
