A large factor might be based on how many slots one has for each (PCIx v SATA ports) and what the PCIx requirements are: i.e. is it fine in a PCIx-1? How many lanes is your PCIx attachment? Seems like that would strongly affect I/O rates you would get. Another factor might be other usage -- like if you are wanting to include it in a RAID -- I noted that most RAID controllers didn't work with on-bus (NVMe) disks.
The benchmarks are for SSD-drives that take the place of hard-drives -- not motherboard attached ramdisks.
NVMe SSDs are current generation hard drives. They aren't ramdisks in any sense of the word. I bought my first one 2 years ago.
---- That you can't boot from. FWIW, I took a 4-disk SSD-RAID0 out of a non-booting system and put it into another, same model machine, and was able to boot it flawlessly. For that reason, I wouldn't call them hardware-based drives. From your description, it's memory that is physically attached via a PCIx interface to the motherboard, no? Memory attached to the system motherboard, used to be how memory was designed into the system before CPU speeds were so much faster than MB speeds (mostly gen-1 PC's and computers before that). The website I cited, doesn't consider them in its bench marks as they aren't hard-disk compatible (can be thrown in another pc to boot from, as 1 example). That DOESN'T mean they might not be a good value for the money. But sometimes being able to take the drive out and put it in another system w/no loss of data or functionality is important. It's too bad Windows can't simply use that type of drive as a cache for a regular HD like linux is supposed to be able to.
The $25 adapters only negative that I know of is that you can't boot off of them typically.
But, motherboards that have the built-in adapter also have boot support. Laptops with NVMe SSD support can also boot off them.
I would hope so..
fyi: it's a bit on the extreme side, but a client had a 2 TB NVMe SSD
nice, wonder how much that cost... -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
