Yea so what. If an NVME SSD is going to run at its fastest rated speeds and needs cooling, I'd buy it if it cheap enough. Even if it doesn't feel faster in daily use but is twice as fast benchmarked, add RGB and I'm in

Trigger warning...
Comedy gold!

At these angles it looks like an extending brace to prop up heavy objects.

Der8auer reviews the Corsair MP700 Elite Gen 5 drive with the new Phison controller. The drive was able to maintain full read/write speeds over a 10 minute test using the included heat sink. It still throttles without the heat sink,. "Gen 5 drives are finally usable" he says, but notes that it probably makes no difference for certain use cases, like gaming.

Now they just need a competitive price...

I've completely tuned out of the Gen5 SSD's, but I'm happy if there's cool running drives finally out. Now they need to be available in 4TB and 8TB to be interesting though.

When Gen5 was about to launch I had saved up and was ready to make the move, but the heat, price, and availability turned me completely off and I got an SN850X instead. Given the snail's pace this is going at I suspect there will be nothing to tempt me for a long time, but I guess I'll keep an eye out on the larger capacities and the random performance.

Yeah, if I'm ever getting one it will be when I upgrade to zen6 and hopefully the premium will not be more than 20% over a gen 4 drive.

I don't understand why there is a cap on M2 drives capacity, no matter the Gen. I bought a 4TB gen3 3 years ago for around 220euro and was expecting by this time I could get a 8TB for the same... Fat chance, there are almost no 8TB drives...

High density NAND needs to get cheaper. They can use these chips in enterprise drives of 15 to 30 TB instead and make way more money. Also, if the 8TB gets cheaper, everyone will buy that and then they would have to reduce prices on the lower capacities even more which is most likely not what they want.

Yeah, the reason why I went X670E over B650E was to have enough M.2 slots.

1x 5.0 and 3x 4.0 + 1x 3.0 (2 lane) should be enough even if they all are filled with 4TB.

Currently rocking 1TB 4.0 +2TB sata

This is on Newegg or was in the last couple days.
Corsair has a waterblocked one.
Crucial has some 14-15k speed ones.

SS, WD, Crucial, and I think a couple others have 8TB ones, in stock or not is something else.

I opted for the WD SN850X 4TB from amazon for 259, same price at Newegg but overall was cheaper due to shipping, and faster shipping also.

I've been running two KC3000 drives in raid0 for awhile.
They don't offer firmware updates for their bug unless you use the windows .exe. I have not had a windows install in over 20 years.
So I went ahead and purchased two T705 Gen5 drives to replace them, after getting email confirmation that Crucial still provides a method to upgrade firmware for non windows users.
The 11.5Watt power usage is high, 12nm for the controller seems to be the culprit.
Wish me luck, hopefully my motherboard's heatsink will keep them cool, also i'll be running them at pcie 4.0 speed, so that should help.

They have the 14k speeds, lmk how RAID0 goes, I really wanted an 8TB but costs were not effective, but my mobo can RAID0 m.2.

Ok, I got them installed. The stutterings/slow firmware issue I had with the Kingston drives is now gone (was like 1/10th speed).
These two runs comparing to some phoronix pcie 5.0 results took me most of my sunday.

2xT705-4.0-md1-01 is my software raid0
2xT705-4.0-md0-01 is my software raid1

Not bad for running in pcie 4.0 mode, they trade blows with the 5.0 ones.
Also, I never noticed temps going over 50c.
Note that these tests are not apples to apples against the phoronix systems, lots of variables/differences.

Weird that the RAID 1 is faster than RAID 0.

The raid0 is faster, I just had a weird naming choice. /dev/md0 was my raid1 and /dev/md1 was raid0
Also i'm wondering if I changed the chunk, stride, and stripe if I might get better performance. I kinda doubt it'd make much difference, but apparently the SSD's nand page size is 16KB. My raid0 is set to 128KB chunk size.
The CPU speed is likely making a noticeable impact given that it is software raid also.

My 990 Pro 4TB rarely gets above 40c. Unless I am copying large files between nvmes.
Bare drive without heatsink easily throttles.


In fact you don't even need gen4, virtually every bare gen3 drive can temperature throttle just by copying large files to it.
No. I ran a gen 3 drive and it got only just warm without a heatsink. However, it was a slow DRAM-less drive, the WD SN550.

As for my 990 Pro 4 TB, stuck inside an external USB 4 enclosure, it idles at 40-41C and with large file transfers, it stays well below 50C.

However, that USB 4 enclosure is designed as a giant heatsink, and is made out of 250 g of aluminum. Here are some pics showing the depth of the fins of the enclosure.



Also, even though the 990 Pro 4 TB is a single-sided SSD. I put thermal pads on both sides of the drive. When I had a thermal pad on only the NAND/controller side, it would peak around 55C or so. With a thermal pad on both sides, it now peaks below 50C.

Anyhow, since we're already at PCIe 4.0 speeds, I think the manufacturers are generally chasing the wrong target. Sure, the enthusiasts might want super fast speeds, but the mainstream needs cooler drives. We should not have to resort to only DRAM-less solutions for cool drives. It would be nice to see DRAM-endowed drives which don't run so hot and which don't require these types of heatsinks.

I wish I could buy something like an SK Hynix P31 Gold in 4 TB and 8 TB sizes.

I went ahead and purchased another T705 and an ASUS Hyper M.2 x16 Gen5 Card (has active cooling).
So i'm going to try 3xnvme software raid, mostly just out of curiosity.
I also noticed that running the nvme drive from the x570 pcie lanes instead of the cpu lanes results in ~10% performance drop in benchmarks.

Ok, I got it working.
With 2 nvme running in the Hyper card and 1 nvme running on the motherboard in raid.
The drives on the Hyper card run about 10c cooler, with the fan off, compared to being installed on the motherboard. It has a substantial chunk of aluminum to spread the heat out.
The Hyper card's fan is kinda loud I can't stand it.
Unfortunately the motherboard bios only supports 1x8/2x4 bifurcation, no option for 2x4/1x8 which would improve air flow to the video card.

I'm maxing out at about 21GiB/s and 4.7Miops, but I have to run my video card at 8x pcie speed.
