Designed to be thin enough for ultrabooks and speedier than SATA III. Perhaps we’re seeing a new trend coming eh? After Apple debuted their new Mac Pro with a PCI-e SSD, consumers all around could benefit from using a new, cheaper, standard.
Enter the Korean tech giant. Announced today, Samsung Electronics will begin mass production (cheaper!) of their new PCI-e based SSDs. The drive (or disk, card, stick, however you want to put it), called the XP941, was specifically designed for ultrabook use and runs at around 2.5 times the speed of an SSD on SATA III.
While I’m not expecting these new drives to be cheaper per gigabyte anytime soon, the speed and implementation as we reach economies of scale will certainly become a benefit for all consumers still stuck on spinners.

how much storage are we talking about here? And won’t that need special drivers for windows installation?
SATA 3 has a theoretical max of 750MB/s without overhead and 600MB/s including overhead due to data transactions. This PCIe SSD is going to have a read speed of up to 1400 MB/s. That’s a bit less than double that of SATA 3’s max, and it is almost triple that of most of today’s SSDs performance.
Unless SATA 4 is in the works, PCIe is the way to go for the foreseeable future considering PCIe 2.0 has a max of 8 GB/s (~13 times SATA 3’s bandwidth) and PCIe 3.0 has a max of 16GB/s (~27 times SATA 3’s bandwidth). So, the PCIe SSD they are using is clearly not utilizing all of the lanes that PCIe 2.0 provides and has a lot of leg room to grow (at least as far as desktop computers are concerned).
Well judging by the picture it’s a single lane PCIe not PCIex16
Yeah of course :P. I was just saying that there is a lot of leg room for SSDs in general with PCIe ^^. Also, I don’t think they are using just one lane, but they are using at least 3x (I believe you can only choose 1x, 2, or 4x). So, Samsung is most likely using 4 lanes of PCIe 2.0 (500MB/s per lane x 4 = 2GB/s).
Isn’t sata mounted on pci-e in the first place? Meaning, all they have to do in theory is increase pcie lanes and thus offer more for sata and in extension ssds/hdds
