Question Samsung 970 500MB and 970 plus 1 TB

[noble750]

Hello, I bought a 970 500 MB 6 months ago but have yet to actually build my system. I'm planning on getting a MOBO with 3 m.2 slots so if I bought a newer 970 plus 1TB and added that with the older 970 will that adversely affect my write speeds since the older one has 2500 MB/S and the newer one has 3500MB/S? configured in raid hopefully. Thanks

The two drives are independent.

RAID?
DO NOT DO THIS

Especially as you've not indicated what RAID level for this, and why.

Clone the 970 over to the 970 Plus to experience the ~1/4 sec faster boot time greatness!


(Skip the RAID....; the standard 970 EVO was a 3400 MB/sec sequential read drive as well; the 970 EVO PLus is but 100-200 MB/faster on sequential reads, but, about 1000 MB/sec faster on writes...)

So I should use the 1TB plus for OS and games and use the older 500MG for storage of non essential stuff? That makes the most sense I think.

I'm curious to know why I shouldn't combine the 2 to make a 1.5 TB unit in raid??

RAID does not stack space like that.
500GB + 1TB + RAID 0 (striped) = 1TB RAID array.
500GB + 1TB + RAID 1 (mirrored) = 500GB RAID array.

Additionally, RAID 0 + SSD's does not give a speed boost as it did with spinning HDD's.
In some cases, it may even be slower than individual drives, due to the overhead.

You will gain exactly zero benefit from a RAID array with those drives.

Which drive for which use?
Performance is near enough identical.

500GB for the OS and applications, 1TB for games and stuff. That's what I would do anyway.

Larger ones are usually somewhat faster and more durable than smaller ones.
We are talking here about extra fast drives so RAID0, even if possible, wouldn't be a reason for it. With HDDs, RAID0 would make drives look like one drive with double the platters and heads and that's only reason it's faster. SSDs don't work like that. To say nothing about actually loosing capacity with 2 different sized SSDs.

Ok, thanks guys. I wasn't aware SSD's didn't behave like conventional HDD's
