Regardless of the steep extra cost, the Optane 900P should be included. If you're willing pay for this then the 900P is also a consideration.

Why do your randread and randwrite numbers lag Samsung's spec by such a huge margin? If your numbers are accurate, then I can't recommend this SSD, as Micron 9200 MAX is offering way much better performance (I measured 760k+ 4kB randread IOPS) at a much lower per TB price (3.2TB for $1700).

Aren't the HP EX920 and Intel 760p based on the same controller? I remember that the 760p performed really well a few months back. It would have been interesting to see how it performs today.

Samsung rates NVMe SSD with 4 workers at QD4 each. It's like running four applications with each on a CPU core and then hitting your drive with requests 4 times for each one. When we have ample software to can operate that way, we'll test that way.

We did run a test like that just to see half a million IOPS and actually got almost 600,000 IOPS.


The EX920 and 760p use the same controller but very different firmware. The HP has a larger write buffer.

I'm looking to reduce wait times associated with start-up, changing characters, and especially loading zones in a game (Elder Scrolls Online). Money isn't a huge consideration (within logical reason). Assume high-end "everything else" (CPU, Graphics, etc). Do I want:
1) a 970 Pro (Windows + Game)
2) a 970 Evo (I keep reading that the differences might be "unnoticeable"
3) two 970 Evos in Raid 0
4) an Optane 900P

My current system runs older "non-M.2 NVMe" SSD's (2 in raid 0) ... so I'm well versed in the difference between them and a hard drive.

Thanks kindly in advance!

The difference between a 970 Pro and a 970 EVO isn't perceivable in a home environment playing games. I would buy a single 970 EVO or something that competes with it like the Intel 760p or HP EX920. If money isn't a problem, you could go with 1TB and install all of the games you want.

I hope this helps.

Interesting, well to me, that the Sandisk extreme pro kept up with the 970 pro in the seq write tests. Since I thought that it was based on the same technology as the new HP Ex920 , its strange that the HP fell behind while the sandisk moved up. Any idea why this happened. Other tests were expectable: Samsung 970 pro: Hp EX920 and onward. Maybe this means that there could be firmware that could increase the HP's performance and conversely the sandisks across all tests. Just a thought.

IMO smaller and smaller designs like the M2 and even reducing to 2.5 inch has drastically slowed growth of larger capacity ssd drives. Although the number of chips they can actually produce (fab limits) is probably moreso the reason.

I have the 480GB pcie optane it's a much more elegant design and can be properly cooled. Just like video card "reference designs" that heavily thermally throttle Imo I see that as a design flaw.

BTW I have Samsung and crucial drives too but they each serve their purpose like cheaper bulk storage, high performance with less writes, etc.

I have the Samsung 960 Evo and I get 3.2 GB/s transfer rates, runs much cooler (almost 15 degrees Celsius difference at load when used as system drive on dual NVMe M.2 Motherboard) than the Western digital M.2, looking forward to get this new 970 M.2

Chris, did you get confirmation from Samsung that Phoenix is 5-core? They did not mentioned it in their press release or datasheet/brochure. However, they do spell out for Polaris in their 960 series brochure.

Definitely not two Evos in RAID0 (RAID is very silly for most SSD use cases), and the Pro won't help much either over the Evo. If you are capable of returning it within 14 days at no loss, and your motherboard either has one of those very rare U2 connectors or your PCIe lanes can handle the Optane 900P/905P PCIe without gimping your graphics card from 16x to 8x, you could try if Optane helps much. Stuff it in the PC, format it, install / copy your game there, see if it's much better, return for a refund.
Overall though, unless your SSDs are of the particularly slow variety, neither the Optane nor the 970 Evo should be a huge improvement for game load times over an existing SSD setup.
