Intel Optane SSD 905P Series (480GB)

Almost certainly 0.1 microseconds. I have no idea what the Unicode point for a greek letter mu is though! I'd normally fudge it with a u.

EDIT: and I note that the article's actually been updated already... *doh*

I thought that was about a magnitude too slow for typical time to first word. Maybe once the request has been routed over a ringbus and bounced off the caches though...

Too expensive for me....but if I needed it perhaps a good buy. But I think I'd be more interested in a RAID solution if it works out better on the cost per gb solution and isn't going to be that slow

Odd that they need an extra power connector, m.2 SSDs manage fine on what the socket provides. Of course, that probably explains the chunky die-cast heatsink - that's a lot of cooling for an SSD. For a 55C temp difference (25C ambient, 80C heatsink) a bare 2.5" drive shaped cuboid should dissipate ~9W, so with the ribs and pins it should handle the 12.4W nominal max sustained draw without needing an air con unit. Of course, that power into ~100g of aluminium would take well over an hour* to get it all up to temp so it should be rare for a workload to get the heatsink fully warmed up

*assuming externally adiabatic and lumped heat capacity it'll take 82.5 mins to increase by 55C, so in practice this would be much much longer

memory latency benchmarks seem to give mid-50s ns for Intel and mid 70s ns for Ryzen, so I think talking about 0.1 microseconds is fair in terms of relative magnitude (when you're saying under 10ms for Optane latency). It still leaves Optane 2 orders of magnitude slower than RAM and only 1 order of magnitude faster than NAND flash, which IMNSHO leaves it firmly in the storage bracket of latency - needs another order of magnitude improvement before it's closer to RAM than storage...

... I thought Optane would get a competitor through QuantX, but haven't heard thing since the QuantX announcement. I wonder what happened with that?

Its being released next year,and both companies developed the tech together,so it makes me wonder whether Intel will release something newer next year.

Compared to five NAND SSDs of the same capacity though, which you could put in a raid 0 or 5 stripe giving you way more capacity and a crazy aggregate IOPs figure?

Well there is that option, or you could just get a 500GB Samsung 970 Evo M.2 drive for an OS drive, saving yourself £350 for some additional storage. Such as 3 additional Samsung 500GB 860 Evo drives for that Raid 5 with pretty decent storage capacity and IOPS. You're still saving money this way as well.

I can see why Micron isn't shipping much XPoint to Intel, the pricing is stupid for essentially minimal gains.

Depends what performance characteristic you were after. If IOPS then sure, if latency though then this is cheaper than RAM.

over priced junk.

Why do people review these and the 900p drives as SSDs. These optane drives really shines and come to life if you use them as cache for slow clunky HDDS.. just think of a 10tb hdd being as quick or faster the a standard ssd drive.



Already Having a "32gb optane memory" and having no trouble with it since buying it xmas time... Just pop it in, set it up, forget about it and it does its thing. Cutting down game loading times in half on my old 640 WD black hdd..

So I am really thinking of buying the "280gb optane 900p" with the M.2 cable, and pairing it up with a nice WD black/gold 4tb drive as my games/storage drive.
