2021年4月6日 · Looking at latency, the P5800X keeps low latency but has a much higher top speed. I wonder if that latency is the limit for 3DXpoint, since the minimum is close in old vs new. The previous P4800X has a slightly lower latency of about 15us at low IOPS, and the P5800X a minimum of about 20us, which it keeps through most of its speed range, far ...

2021年7月2日 · I think there's a fetish for super fast storage in the consumer space because we all remember the crazy performance gains from switching to SSDs from hard drives and we're still chasing that high.

2023年5月20日 · With two Optane P5800X in RAID0 using RAIDXpert, I was getting 14,811 MB/s read for SEQ1M Q8T1 in CrystalDiskMark . About a year passed, I ran it again, and now it's down to 7,469 MB/s read . Any ideas why or what can be done? I'd expect performance to stay constant, despite having 16% more files on the drive.

The p1600x is basically a p5800x with a neutered pcie bus. I suspect it's slightly outperforming the p5800x because it's a direct m.2 connection unlike the p5800x which needs an adapter adding overhead. It's also part of why I'm saying it's such a good drive, ur …

2021年7月2日 · It's mostly about low queue depth, small block size reads (most common things in operating systems, databases and most programs) it's very low latency and it's often good enough to act as a next level RAM a la page file.

2021年11月11日 · My new 480 GB P5800X just arrived. I skipped building custom in flavor of Dell workstations the last two rotations so I'm a bit out of the game. I didn't even realize this drive has the new U.2 format, or what that even entails. As long as the motherboard has a M.2 that supports PCIe 4.0 x4 I could use a U.2 to M.2 cable correct like this ...

2022年4月15日 · I see on all review websites the P5800X has around a 5600MB/s SEQ1M Q8T1 on CrystalDiskMark For whatever reason my 400GB model only gets around 4600MB/s - seems unlikely that 400 vs 800 would differ by this much Other metrics such as sequential read and RND4K all match review sites so I'm wondering what could explain this.

2021年6月10日 · I tried to bench my 900P with Iometer on my Ryzen 2600 machine and guess what, it's so latency intensive that moving your cursor and cross CCX data exchange causes significant performance penalty.
