So it looks like Pcie5 nvme drives are coming 2022.

APACER Shows Off Next-Gen PCIe Gen 5 NVMe Consumer SSDs: Up To 13,000 MB/s Read & 12,000 MB/s Write Speeds With Heatsink Cooling

APACER has revealed the first consumer-grade PCIe Gen 5 NVMe SSDs that offer blistering fast transfer speeds of up to 13,000 MB/s.

It's all based on the current the drive is able to pull. Different gens have different current limits. A gen5 in a 3 slot should be at 3 temps.

Gen5 wouldn't really be an option without z690 and above since PCI5 didn't hit board until then. or Zen4 if you're thinking AMD.

 

[Zoozuu]

Not thinking zen4 or z690. I was yammering about the gen5 ssd temperature in gen3/4 port not really about needing to use it. speculation about how it performs.

 

[MysteriousThing]

Aren't they talking about making gen5 drives wider? I read a few articles talking about how they might be 2580 instead of 2280. Would they even fit then in current M.2 slots?

 

[Tech Junky]

Still uses the same M2 characteristics to connect to the MOBO... just a bigger PCB flanking the chips / controller.

 

[Zoozuu]

the articles also said they were backward compatible. I'm guessing there are wide port and regular sized. Even if there aren't that isn't much of a loss.

 

[Tech Junky]

The 3mm extra on the PCB isn't a big difference for clearance.

The good high end PCIE 4.0 SSDs all score 80-90+MB/s on the 4k random Q1T1 reads. That showing is poor for the E26 drive.

Is it actually getting 80MB/s? Because all the reviews are showing 60MB/s. 60MB/s is 15K IOPS, which is the fundamental limit of NAND flash for reads.

You need a better media to get better speeds than that. Interface is not the bottleneck at all.

A interesting article that isn't about our favorite drives. Here.

I would not trust their new tests. They are testing it with drive nearly empty. That's how most reviews get 60MB/s max, but tweaktown is getting 80MB/s. I don't know why they changed this, because the older reviews weren't like that.

I have a 980 Pro 2TB that's 87% full that still sees 86MB/s on the Q1T1 4k random reads per crystaldiskmark. I'm not sure what information you're basing any of this on as you've cited no source or real explanation other than "nand just can't go that fast so it must be false"



Anandtech's own testing shows the SN850 seeing 100MB/s empty and 71MB/s at 80% full. They have a different testing suite than using crystaldiskmark, but that's still ~19% higher than the alleged 60MB/s limit. They also have tested very, very few high end PCIE 4.0 SSD's.

Anandtech also tests with a 3600X, and I have seen testing done that shows Alder Lake having superior I/O, getting higher speeds even on the 4k randoms than zen 2/zen 3. Tweaktown is testing with an alder lake system.
