PCIe SSD Faceoff: Samsung XP941 (128GB & 256GB) and OCZ RevoDrive 350 (480GB) Tested
by Kristian Vättö on September 5, 2014 3:00 PM ESTAnandTech Storage Bench 2011
Back in 2011 (which seems like so long ago now!), we introduced our AnandTech Storage Bench, a suite of benchmarks that took traces of real OS/application usage and played them back in a repeatable manner. The MOASB, officially called AnandTech Storage Bench 2011 – Heavy Workload, mainly focuses on peak IO performance and basic garbage collection routines. There is a lot of downloading and application installing that happens during the course of this test. Our thinking was that it's during application installs, file copies, downloading and multitasking with all of this that you can really notice performance differences between drives. The full description of the Heavy test can be found here, while the Light workload details are here.
In our 2011 suite the 256GB XP941 is still strong, but the 128GB model and RevoDrive 350 are no better than a SATA drive. The 128GB XP941 simply lacks parallelism because of its small capacity, whereas the RevoDrive is better suited for very intensive workloads (like the 2013 suite). The average service times (although not graphed here) are still better than what SATA drives offer, but the truth is that a RAID array will only help if there are more IO to process i.e. in high queue depth and large transfer situations.

Not sure if this is technically possible, but I see a killer niche product of making a "generic bootable" NVMe PCIe card that presents whatever BIOS and/or uEFI code needed to bootstrap legacy systems with any M.2 or (possibly?) ajoining PCIe SSD of your choice?M.2 is obvious, just snap it onto the PCIe card.
I know in the old PCI days, some SCSI cards could boot ajoining cards for you also (Adaptec, LSI) but I was never sure that had to be vendor specific or not (probably).
Again it probably would take so much effort and be a compatibility hell, but I dunno, it would be nice.
Or we could get lucky, and bootable PCIe SSD's just take off as a common thing, so older systems can get into the game. Maybe...

Yep, If they can make PCIe x4 or x8 cards that will translate into about 1000MB/s or 2000MB/s using PCIe 1.0/1.1 (bus speed). If you have some old board that have a second x4/x8 slot you could add one of these little things and still have a really fast system. Many good old boards have them and had support for 8GB DDR2 and quad core CPU's. So... you could still have a really fast system out of and old platform. (Phenon x4/Core2Quad/Modded Xeons).mohsin1994 - Monday, September 8, 2014 - link

Hi,For secure erasing PCIe drive, what software did you use ? Thanks

Today my XP941 256GB also died. I have not used any erase-tools. It died while PC was running idle with a bluescreen. My board is an ASRock z97 Extreme6. First I thought about the board or the power-supply but a test in another system confirmed it has gone after only 5 month in 24/7 running. Ambient temperatur is controlled at about 30°C so this is not the problem.andrewk18 - Monday, January 9, 2017 - link
Is there anyway to get the ocz revodrive 350 to work on mac pro 5,1?
