Sabrent's Rocket X5 PCIe 5.0 NVMe SSD Shown Hitting 14 GB/s Read Speeds

[JoeTheDestroyer]

Even if Intel stops supporting Optane as cache, it can still be done w/o Intel's software. (PrimoCache, comes to mind)

I'm doing exactly this on my AMD system (7950X3D, X670E).

I want Optane but i can't get it at decent pricing.

Decent is pretty vague. I paid $340 for my 905p (~1TB). Yes, more expensive than a flash SSD, but not impossibly so. (About once a month, Newegg puts them on sale for that price for a single day.)

In Canada that drive is uber expensive. You could buy about 9 1 TB NVME SSds for this price.

So 106MB/s random reads. For comparison the budget WD580 does 89MB/s, so only 20% improvement despite fancy 232 layer nand and current state-of-the-art tech.

At this rate we may carch up to optane when PCI-E 8 drives come out with 500 layer nand and 70W idle power.

Progress is good, but NAND latency bottlenecks still prevent SSDs from becoming any faster in the real world.

As I periodically state here, the real world will have to rebuild itself around NAND latency. Long latency is a given, it looks like it'll never go away, but queueing brings immense acceleration. Yes, I understand it's far from trivial for developers to achieve that.

Its a shame that really the only improvement over last gen is sequential.
The only way you'd benefit is having two of these drives transferring large files between them.

Maybe not even then if you run into thermal, or cache overflow problems.

Optane solved it, but was never successful enough in the market to get the investment and improvements that NAND has had. NAND SSDs started life at SATA2 speeds with 200ns latency good for 5K IOPS and now were at >10GB/s with 200K IOPS.

Optane's starting point was better than NAND's starting point, but unlike NAND, Optane wasn't entering the market as a revolutionary new technology that was desperately needed. SSDs are good enough and there's little call for lower-latency storage, especially not at the prices Optane was selling for.

Given NAND SSDs are here to stay, the hope is (as you say) that the real world will adjust. Hopefully NAND-aware software, drivers, and OS evolve to the point where hardware tiers can be managed seamlessly from CPU to RAM to cache to <small 3D Xpoint buffer?> to pSLC cache to TLC/QLC NAND.

The high pitch fan was changed a few weeks after launch to an optimized version with 50% less fan speed, 3-pin connector, and the same air flow. Very few of the old version were actually shipped outside of Japan.

The CDM RRQD1 of 106 is still on an early drive that has not been fully optimized. The next update will be from Flash Memory Summit in a few weeks.

I'm surprised you compare NAND to Optane. E26 ships up to 4TB right now. How much does a Gen4 4TB Optane drive cost? It doesn't exist. How much does a 2TB Optane drive cost....It doesn't exist either.

They both exist.

Large capacity optane are enterprise drives, typically U.2.

They go to 1.5TB.

I haven't seen that one. I'll have to order one this week for "testing purposes".

BTW, it costs $6,400 so it's not like most people will actually buy one for a consumer system.

There's 5801 models and a whole bunch of 4800 series as well. More too that I can't remember the name of.

Mostly I've seen them on EBAY, not many outlets seem to have much stock.

I'm not sure what the difference is between the different models. I think the 4xxx is gen 1 and the 5xxx is gen 2, but haven't looked into it too deeply.

 

[Chris_Ramseyer]

I have all of them other than the 3.2TB 5800 and 5801. I never knew they released those. For most of the Optane life-cycle I was a reviewer at Tom's Hardware and TweakTown so Intel sent them direct. For the later ones I just bought them for work.

I think this is the full list.

I'd love one of these drives but as a student can't really afford the price lol.

Oh well, maybe when I'm a consultant. I doubt there'll be anything that comes close to these numbers for endurance even then.

I haven't seen that one. I'll have to order one this week for "testing purposes".

Do you post your test results anywhere?
