I don’t think there is any other way to say this other than to state that the XP941 is without a doubt the fastest consumer SSD in the market. It set records in almost all of our benchmarks and beat SATA 6Gbps drives by a substantial margin. It’s not only faster than the SATA 6Gbps drives but it surpasses all other PCIe drives we have tested in the past, including OCZ’s Z-Drive R4 with eight controllers in RAID 0. Given that we are dealing with a single PCIe 2.0 x4 controller, that is just awesome.

Listen well as you pine away for your very own SSD SATA drive. One day you will get that new thing. But what you really, really want is the new, NEW thing. And that my friends is quite simply the PCIe SSD. True the enterprise level purchasers have had a host of manufacturers and models to choose from in this form factor. But the desktop market cannot afford Fusion-io products at ~15K per card fully configured. That’s a whole different market there. RevoDrive has had a wider range of products that go from heights of Fusion-io down to the top end Gamer market with the RevoDrive R-series PCIe drives. But those have always been SATA drives piggy-backed onto a multi-lane PCIe card (4x or 8x depending on how many controllers were installed onboard the card). Here now the evolutionary step of dumping SATA in favor of a more native PCIe to NAND memory controller is slowly taking place. Apple has adopted it for the top end Mac Pro revision (the price and limited availability has made it hard to publicize this architectural choice). It has also been adopted in the laptops available since Summer 2013 that Apple produces (and I have the MacBook Air to prove it). Speedy, yes it is. But how do I get this on my home computer?
Anandtech was able to score an aftermarket card through a 3rd party in Australia along with a PCIe adapter card for that very Samsung PCIe drive. So where there is a will, there is a way. From that purchase of both the drive and adapter, this review of the Samsung PCIe drive has come about. And all one can say looking through all the benchmarks is we have not seen anything yet. Drive speeds which have been the bottle-neck in desktop and mobile computing since the dawn of the Personal Computer are slowly lifting. And not by a little but by a lot. This is going to herald a new age in personal computers that is as close to former Intel Chairman, Andy Grove’s 10X Effect. Samsung’s PCIe native SSD is that kind of disruptive, perspective altering product that will put all manufacturers on notice and force a sea change in design and manufacture.
As end users of the technology SSD’s with SATA interfaces have already had a big time impact on our laptops and desktops. But what I’ve been writing about and trying to find signs of ever since the first introduction of SSD drives is the logical path through the legacy interfaces. Whether it was ATA/BIOS or the bridge chips that glue the motherboard to the CPU, a number of “old” architecture items are still hanging around on the computers of today. Intel’s adoption of UEFI has been a big step forward in shedding the legacy bottleneck components. Beyond that native on CPU controllers for PCIe are a good step forward as well. Lastly the sockets and bridging chips on the motherboard are the neighborhood improvements that again help speed things up. The last mile however is the dumping of the “disk” interace, the ATA/SATA spec as a pre-requisite for reading data off of a spinning magnetic hard drive. We need to improve that last mile to the NAND memory chips and then we’re going to see the full benefit of products like the Samsung PCIe drive. And that day is nearly upon us with the most recent motherboard/chipset revision from Intel. We may need another revision to get exactly what we want, but the roadmap is there and all the manufacturers had better get on it. As Samsung’s driving this revolution,…NOW.
