Hmm. Pretty much a tie in 4.0 x4. Not seeing 5.0 x4 M.2s over 2.0 M IOPS, though.

Don’t know of comparative thermal data but U.2 has less surface area than NGFF under something like Cogage H2 Pro, it’d take substantial LFM to match the airflow, and at least ASRock’s started heatsinking the underside of 5.0 M.2s (B850 Steel Legend, Pro RS, Riptides). Also Micron says 0.8 Ws/GB for the 9550s, which is higher than E31 (and pending SM2508 drives as well as presumably Presto).
ahhh, the D4800X prices do line up with the comment for both the 375GB and the 1.5TB drives.
I always stayed away from them because I saw so many forum posts about firmware and formatting issues; but if these could be resolved the only downside would be they are half the normal P4800X’s speed.
With this, you’ve basically grasped the essence of the Iron Triangle, but there are four vertices, so maybe this is more like a pyramid.
Even without having “cost” as a vertex, “all of the above” is unattainable. Something you maximize will minimize something else.
I still don’t understand your priorities. And I don’t think you’re sure either.
Your best may be attainable, but you haven’t defined what your system needs to be best at. You’ll have to figure out what you actually need.
The distribution of file types, sizes, access pattern, and access frequency are a good start.
How you use your workstation and what you use it for is another.
Generally, boot drives lean on random I/O. I assume you have personal files and such on some other device. In most cases, clever OS tricks already mask mediocre random I/O. That is unless you are always running out of memory. But for most people, spending extra to cover the uncommon edge cases just to preempt all of the occasional hiccups is not the best investment of resources.
Yeah.
For me, the idea is to get the best drive, that a regular person (mere mortal) can buy.
So, I’m not looking for the best “bang for buck”, but I also can’t afford to buy extremely expensive drives.
That DC P5800X starts looking more appealing, to me, by each day.
I’m thinking about buying the 400GB P5800X.
It should be large enough, as a boot drive only.
And, being smaller doesn’t mean that it’s slower (as it’s the case with NAND based SSDs).
Ive run boot drives on little 128gb ssds and they were fine for os boot duty. Was going to drop a C note and get the d4800x 375gb. Always wanted an optane boot drive, and the 1.5tb does seem like overkill for handling the os.
Just realized the big difference between d4800x and p4800x… looks like it’s best to avoid the D series, it’s not very proconsumer friendly.
I’ve, previously, based my opinion on an old interview that I’ve seen with an Intel representative who said that size doesn’t make a difference, in terms of speed, when talking about Optane drives.
Depends on which speed. For 512-byte sector random reads (QD1T1), I’ve gotten around 42~43 MB/s across all generations/series of Optane on my Ryzen 7000 series systems. For 4 KiB random reads, it’s 340-ish MB/s.
They will show their differences once you throw more parallelism and larger read sizes at them.
I recommend the Corsair MP700 Pro SE with Air Cooler. It’s faster with PCIe Gen5, has a large 8GB DRAM cache, and includes a cooler to prevent overheating. It offers the best mix of speed, cooling, and reliability.
Yeah.
I’ll think about it.
The only thing that I dislike about that SSD is the fact that it has a tiny fan, which will become noisy, as it will collect dust, over time.
Another thing to not like about m.2 NAND NVMe drives is that they will let your data get slower and slower the longer it has been written onto the drive… I’m pretty sure Optane doesn’t suffer from this.
