PCIe SSD Faceoff: Samsung XP941 (128GB & 256GB) and OCZ RevoDrive 350 (480GB) Tested
by Kristian Vättö on September 5, 2014 3:00 PM ESTPerformance vs. Transfer Size
ATTO is a useful tool for quickly benchmarking performance across various transfer sizes. You can get the complete data set in Bench. The ATTO graphs highlight the biggest issue the RevoDrive has. At small transfer sizes the performance is substantially lower than what SATA drives offer and it is only at 128KB where the RevoDrive starts to benefit from PCIe and RAID. It does close to 2GB/s with 8MB transfer size but for users that figure is fairly meaningless because IOs that large are rare.

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?
