Hi folks,

I'm looking for a 2Tb m.2 nvme ssd that will sustain around 1000MB/s indefinitely. I know they'll pretty much all do this to start but then as the cache fills, the data rate will drop.

It's going to be used in an external enclosure that won't go above 1000MB/s so anything above this is redundant but there will be quite a lot of data being moved backwards and forward so it needs to sustain that rate.

Any suggestions please? Doing this on a budget so I'm looking for the cheapest available option.

Thanks.
 
Hey Feek, to get more bites I think you will need to provide more detail about what you're trying to achieve. As the recommendation might change depending on the size of the files or the workflow.

I stumbled across this and filtered it to the information above. Hopefully you will be able to find a high performance drive that is following the downward trend in pricing.

Depending on what you're transferring, you could also consider a RAM disk, but then you would have to take extra precautions like a UPS etc.
Now you've made me want an Asustor Flashstor again which I had forgotten about :cry:
 
That's a useful site for comparison, thanks. I don't think the usage is really relevant as it'll just be continual reading and writing of a mixture of large/small files pretty much all day. A RAM disk isn't really suitable.

Samsung 990 Pro 2 TB Review

Samsung 990 Pro is the company's flagship M.2 NVMe SSD. Compared to the 980 Pro, it comes with an improved controller and more modern flash. Our review confirms: this is the fastest PCI-Express 4.0 drive you can buy right now, beating the competition from WD, Phison and Solidigm.

looks like 990Pro has no problem sustaining 1000MB

And there are couple more suggestions in the bottom chart

Absolutely agree with that, I have one already running in a 40Gbps enclosure but unfortunately it doesn't meet the 'cheapest available option' as it's quite a pricy drive.

That's actually a useful part of the review, I was considering the P5 Plus which might be a good performance/price point.

It was more to discover your requirements as we didn't originally know if you were transferring large files or tiny files (sequential/random writes). Although less important these days as things have improved so much. Even write endurance has shot up. This guy has some calculators that could be used to estimate performance/endurance. https://wintelguy.com/endurance-calc.pl

You've timed it perfectly to meet the budget requirements!
 
I'm not sure buying a cheap drive and hammering it as hard as you are is the best idea. Is longevity an issue? Because it sounds like your going to be using the drive quite hard and I'm not sure how long an SSD will last in those conditions.

I'd be tempted to RAID a pair of drives, but this isn't possible as you want to use an enclosure.
