Deathspawner writes: Samsung’s SM951 is an unassuming gumstick SSD — it has no skulls or other bling — but it’s what’s underneath that counts: PCIe 3.0 x4 support. With that support, Samsung is able to boast speeds of 2, 150MB/s read and 1, 550MB/s write. But with such speeds comes an all-too-common caveat: you’ll probably have to upgrade your computer to take true advantage of it. For comparison, Samsung says a Gen 2 PCIe x4 slot will limit the SM951 to just 1, 600MB/s and 1, 350MB/s (or 130K/100K IOPS), respectively. Perhaps now is a bad time to point out a typical Z97 motherboard only has a PCIe 2nd Gen x2 (yes, x2) connection to its M.2 slot, meaning one would need to halve those figures again.
