I am inclined to agree with popatim but for a different reason. The new SATA 3.2 standard which was officially adopted last year is still in its' infancy. Motherboard manufacturers are starting to include the first of the new M.2 NGFF headers/connectors on new Z97 motherboards. Unfortunately all but one motherboard does not adequately support M.2 NGFF solid state drives like the Samsung XP941 M.2 ssd. The M.2 NGFF headers/connectors should be using a minimum of 4 PCIe channels to transmit data. With one very notable exception, all of the new Z97 motherboards have M.2 headers that only use 2 PCIe channels. It will probably take the rest of the year for motherboard manufacturers and ssd manufacturers to make the necessary improvements. This is definitely a wait and see what happens situation.
I normally recommend Samsung ssd's. Samsung ssd's perform well and have a proven track record. Crucial, SanDisk, and Intel are also worth considering.
I maintain the ssd database listed in a sticky at the very top of this forume section. Here is the link:
