Thoughts on these SATA/M.2-->SATA/2.5" adapters?
(feddit.nl)
Trying to squeeze some more storage in my MiniPC. I have questions about these. These use hardward RAID with selectable modes (Individual/JBOD/RAID1/RAID2).
-
If I use RAID 1 and one of the drives fails, will I know?
-
If a drive fails, and a slap in a new one, will it internally begin repairing RAID 1 again?
-
Can I use these as "individual" or JBOD and have 2 separate drives through the same connector, and use something like TrueNAS to software-RAID them?
If you don't have a bunch of nvmes lying around that you want to use, then why not just go for a few sata drives and raid those together? You do what you like, to me that just seems like more storage for your buck
Just as an uninvolved third party, I'm trying to figure out how NVMe entered this response to a question about a SATA to SATA form factor converter
Because M.2 equals NVMe in some people’s minds, I suppose
Right, mostly because the only things you plug into an m.2 slot right now are nvme drives. Which is why I'm honestly trying to figure out what OP wants. They say speed isn't a concern just storage, so why not go for a larger SATA SSD then? Unless I'm missing something, buying this adapter to add m.2 slots would only give op a couple m.2 slots, vs just adding a sata drive itself. Honestly I don't know what they're trying to to do and their comments have made me more confused
My desktop has a wireless card in an m.2 slot (as do those of my wife and both children), one of my laptops has a SATA m.2 as its only drive because it only has a SATA m.2 slot, another laptop has a SATA m.2 as the scratch drive because it has one NVMe and one SATA, and "the only things you plug into an m.2 slot right now are nvme drives" is such a wild take that I'm baffled as to where it came from
Because there's no redundancy.
Which is fair, I suppose, if you really only have one SATA port left. Then a RAID 1 through that device might work well enough. Wouldn’t be my first choice though… and definitely not for RAID 0. Not that RAID 0 should be anyone’s first choice, nowadays.
Just making the best with what I've got.
Neither is there if this controller dies.... Like the other person said, my response would be "you don't have 2 sata ports then?". Better raid support and better capacity. Take it from my life lessons. Raid 0 is not a backup, it is barely redundant. It's primary use is production environments where you do not want your system to go down when a drive fails.
Yes. There is. Unless the controller decides before it dies to wipe the disks for some reason?
And like I said to the other person, "No."
No one is talking about backups.
Okay, I don't know why you're downvoting me, and I'm over it. I was trying to help you and understand the question, I was trying not to be argumentative. My honest responses haven't changed on your questions, I think it's going to fail quickly, I think you're going to regret it, and I don't think it's good for your use case. But hey, what do I know, I've only done basically the same thing and self hosted stuff for 15 years, and was only trying to help you avoid the mistakes I made. Sorry I didn't just agree with everything you said and was trying to figure out alternatives.
I don't have any way to add them.
But you adding nvmes on the same slot?
M.2 is a form factor. Under that form factor it can run the NVMe or the SATA protocol.
No.
What are we seeing here?
This is a SATA/M.2 to SATA/2.5" adapter. No NVMe.
