Isn't optane something like 2x-3x the price for marginal gains and worse write latency?

Isn't optane something like 2x-3x the price for marginal gains and worse write latency?
- wtallis 6y agoMore like 6-8x the price. I don't think I ever saw the Optane SSDs get below $1/GB, and the SN850 is $0.20/GB.
- ComputerGuru 6y agoThe 905p in 480 GB is supposed to be around $600 making it only 3x the price, but good look finding it. Intel doesn’t even MSRP it any more, although it’s still an active product.
- Dylan16807 6y ago3x the price of the 1TB model. 5x the price of the 500GB model.
- modzu 6y agono. optane is something like twice the speed of the 850 at random read. have it as a boot drive and ive been living in the future. i mean its great something like the 850 is as cheap as it is. but i can barely tell the difference between that and any sata drive. to be fair, it depends on your use case. look at real world benchmarks measured in human timescales (actual honest comparisons are rare in these reviews, because then this stuff wouldnt sell affiliate links). i cant help but feel consumer pc parts are merely for videogame consoles. the ssd and ddr speed crap, lack of ecc, etc.. building machines with this stuff is almost like a videogame itself -- my ssd scored 1,937,533 points on synthscore 3.5! (like, it saves 9.5 minutes of my life over 365 days compared to a samsung lolz)
- nine_k 6y agoM.2 drives are small and usually don't require a cable and a bay. It is important in compact builds. Funnily enough, recent AMD CPUs for the consumer segment support ECC out of the box. But you need a right motherboard, of course. This is a welcome streak of sanity in the world where consumer PCs have 32GB RAM.
- my123 6y ago> recent AMD CPUs for the consumer segment CPUs yes, but not APUs. This matters especially for SFF builds where you might not want a dGPU. For those, you specifically have to hunt for Ryzen Pro APUs which do have ECC support.
- modzu 6y agoi can only find one single motherboard that supports ecc for the new ryzen. im glad amd isn't crippling it, but for all intents and purposes the support still isn't there
- Godel_unicode 6y agoYou might want to check out the ASRock rack X470D4U, as long as you're running either a desktop CPU or a pro APU. If you're specifically referring to a non-pro APU then yes you're likely out of luck.
- vbezhenar 6y agoFor low queue-depths benchmarks gains are not marginal. It's 10x faster. And write durability gains are not marginal either, it's 30x more (compared to Samsung 980 Pro). An issue is that even SATA SSD is fast enough for most users and write durability of even modern QLC disks is good enough.
- Godel_unicode 6y ago>...10x faster. That's absolutely not true. I encourage you to re-read the article. The very specific case of qd=1 random reads are 4x (less than half what you suggest) faster, however in that scenario you probably care about latency more than speed. Also, qd=1 random reads are uncommon in disc-bound real-world scenarios. There are plenty of benchmarks which have the optane close or losing, and as benchmarks become less synthetic the gaps largely disappear. The gains are marginal where they exist, and the price is outrageous. The problem is that optane is an appealing idea which simply failed to pan out.
