5 out of 5 eggsFastest consumer level SSD on the market

Pros: The first drive not bottlenecked by it's interface in years. The 2GB/sec the pci-e x4 lanes give provide enough bandwidth to let this ssd fully stretch it's legs. Easily hits 1.4GB/sec.

MLC 2 bit per cell nand provides more than enough durability for home usage, the pc will die long before the endurance runs out on the cells. Even TLC 3 bit per cell nand has proven itself reliable for home use.

The drive is made by Samsung. This is a huge pro and it's not because I am a samsung fanboy. Samsung has a very unique position in the SSD market. They control every part of their ssd from the nand cells to the dram cache to the controller to the firmware. It is all designed and manufactured by Samsung. This allows them to get unparalleled levels of compatibility. It also allows samsung to get every ounce of performance squeezed out of the configuration since they designed every nook and cranny of the ssd they know how to get the most out of it and can custom write their firmware to be as efficient as possible and that is exactly what this drive is.

If you want to own the pinnacle of SSD performance this is the drive you want.

Cons: There are always some cons as well nothing in this world is perfect. The price for this ssd isn't the greatest. Nowadays anything over 1 dollar per mg is a very premium price for a consumer home use ssd. You can easily find high performing 512GB SSD's in the 50 cents per GB range.

The m2 slot is still fairly uncommon it's not easy finding a home for this ssd and most people will need a new motherboard if they want to take advantage of the fastest ssd on the market.

Shorter warranty than most premium ssd's. This has a very premium price where is the premium warranty?

The controller supports pci-e 2.0 instead of 3.0. More of a neutral than a con just slightly con because the actual nand isn't even fast enough to saturate the 2.0 x4 connection.

No 1TB capacity offered. SSD's have seemed to concentrate into 4 main capacity points: 128GB, 256GB, 512GB, 1TB. An SSD line should offer something near all 4 levels. Prices have come down so much most people are buying 256GB at the very smallest and 1TB is much more reasonable to buy with prices as low as 40 cents per GB 400 dollars for 1TB. Many people would like to see this offered in 1TB capacity.

Other Thoughts: I hope samsung increases the availability and marketing of the pcie-3.0 successor to this drive

The even FASTER Samsung SM951 the first consumer home use SSD with a native pci-e 3.0 x4 controller is right on the horizon. It uses NVMe instructions allowing the system to take advantage of the characteristic specific to nand over pci-e. Previously AHCI instructions have been used and they were designed with big spinning platters as the storage medium. By switching to NVMe speed is increased power use is decreased. These drives are rated at under 10 mW (0.0099 W or less) power use during idle and that is lower than all the other ssd's currently out.

Slated for released 2nd half of 2014 which is why I bring this model up. It should see it's release very soon and will steal the performance crown from the xp941. Before you commit this high of a premium price because you want the fastest ssd in the world you should definitely wait for the sm951. If you cave and buy the xp941 you will only have the fastest ssd for a few months instead of a whole year or more.
