Here's the link: 350GB DELL MICRON SLC PCIE 2.5 INCH SSD SAS SOLID STATE DRIVE MTFDGAL350SAH $260/ ea

I got two of these awhile back for $1/GB. These are PCIe 2.0 drives like the Fusion-io but they work in NVMe drive slots/ cables. I think when we benchmarked them they were like 1.7GBps so faster than many of the Fusion-io drives.

SLC + PCIe = low latency and like 10 dwpd endurance. Ultra hot!!! I'm out of servers to put these in.

About the same $/GB as a Intel 750, cheaper than the 950 pro. Have power loss protection like the 750 but ridiculous write endurance.

Really nice find. I have 4 of these drives and actually prefer them to the Fusion-io ones.

Nice find! But how do you connect these in something else then a Dell Poweredge G12?
Use the 2.5" NVMe guide. Same connection conversion as the NVMe 2.5" drives. Also, the R730xd can have slots that work with these and a few other models.

in a couple of days ill let you know if they work in the intel cages. as i found out yesterday we can connect an Intel cage to the supermicro card.

Yes you can! Too bad getting those Intel cages into other servers is not so easy.

Quick tip - the driver file on the Micron page has a file name that a few OSes do not like. Two tips:
Rename it (e.g. I did to B145.gz)
Even though it is a .gz file, it is a tar archive also. tar -xzvf not gunzip

I may have a system with these working :)

Raw throughput wise, the NVMe drives are good. But sustained writes with SLC these are actually very nice.

Naeblis, if you don't mind sharing, what "dedup" software do you use? Is it effective? Time to create dedup version first time? Afterward is it real time and automatic? Any reason not to use dedup? Others?

yes i did thank you. I was getting ready to buy 2 800GB intel 750's. so this saved me $400. with the extended write performance i can dedup them to make up for the size difference

i used the built in version with windows, savings is massive, file servers, Hyper-V replicas servers, and VDI's 4-500 GBs go down to 40GB

i usually set the age to 0 days, and as i am coping items over I manually run jobs, so i don't fill up the drives before the dedup jobs reduces the space. This is especially important for SSDs

as far as SSDs go here is the usages for my main laptop for 2 years of usage and i did dedup my VMs (x 2 as it was raid 0)

the pics dont take into account the deduped blocks that don't seem to show up in the accounting..

but out of 4 TBs i am using 3.46 TB with 2.21 TB free :p

Naeblis, thanks for sharing. You wrote>"..i usually set the age to 0 days, and as i am coping items over I manually run jobs, so i don't fill up the drives before the dedup jobs reduces the space. This is especially important for SSDs ..."

About Data Deduplication (Windows)
says
"When new files are added to the volume, they are not optimized right away. Only files that have not been changed for a minimum amount of time are optimized. (This minimum amount of time is set by user-configurable policy.)"

I have bit level implementation that always does this in real 'blink' time regardless of size of existing or new material. Do you think this is worth commercializing? Anyone?

NOT MS technology. It is patent pending and at this time would require a non-disclosure agreement. I am in need of machine/assembler level/macro assembler level programmers experienced in Intel, AMD, and ARM hardware instruction sets. Also FPGA programming abilities. If people have the time and desire to contribute you can send resumes as private message.

Seems like we are a bit off topic. Maybe time for a new one?
