    Other any other difference between the Intel Optane P4800x & P900 other than their endurance rating (20.5 vs 5.11 PBW), MTBF (1.6m vs 2m), and Enhanced Power Loss Data Protection? I also read that the P4800x has the option to change the sector size. I've also seen some benchmarks where the P4800x performed slightly better on some tests.

    The reason I ask is because I purchased a P4800x and believe I may do fine with just a P900. The return window is still open. I'm curious what you guys think.

    I deploy 900p and 905p drives on any machine that is running databases at this point. We are budget constrained so two 900P / 905P in RAID 1 at prices lower than a P4800X is worth the slight feature differentiation.

    Yep, agree with Patrick we do the same, it's even nice and affordable to throw 1 in an E3 setup :D

    My server does not support a U.2 drive. I only can go with the AIC version of the NVMe drive, so RAID1 is not an option for me. My server is a HPE ProLiant DL325 G10. AMD EPYC 7401P /w 8x 32GB RAM. Based on my resesrch the P900 is almost the same performance wise. The only difference that appealed to me is their Enhanced Power Failure protection. Right now I can't make up my mind if I should just return the P4800x and get the P900 or not... hoping to hear some more input from you guys.

    Also I heard that there are better drives available for the P4800x over the P900. Not sure if that's just a Windows thing of not. I will be running the latest Ubuntu. Does Ubuntu have the optimal software/drivers to maximize the P4800x's performance?

    I'm nowhere near as knowlegable as the above rockstars, but I'm happy to share my thoughts as I have 4 905s.

    3 points that haven't been attended to that I'll comment on:
    • The sector size change you are referring to is facilitated by isdct, which does not function with the 900p. Frankly, I miss using it previously with a P3700 and find the extremely limited SMART data provided by ESXi (vs. isdct) to be quite annoying. Further, isdct allows for control of a number of variables beyond just sector size which can't be changed on the 900p.
    • I'm not sure if you are referring to the lack of an ESXi VIB for the 900p or not, but one is available for the P4800x but not the 900p. Of no real consequence I suppose.
    • But here is a kicker for you while on the topic of ESXi:
      • Use the 900p in ESXi = void your warranty
      • Additionally, the Product will not be subject to this Limited Warranty if used in:(i)any compute, networking or storage system that supports workloads or data needs of more than one concurrent user or one or more remote client device concurrently;(ii)any server, networking or storage system that is capable of supporting morethan one CPU per device; or (iii)any device that is designed, marketed or sold to support or be incorporated into systems covered in clauses (i) or (ii)
      • https://www.intel.com/content/dam/s...-storage/intel-client-ssd-module-warranty.pdf
      • I would imagine this would absolutely impossible to enforce and if I had to guess why this clause exists = it would be to ensure "Enterprise" and "Ethusiasts" stay in their respective lanes and given the similar performance you mentioned but the 900p being much cheaper, it may be simply a scare tactic to ensure enterprises are not purchasing nearly equally capable 900ps, which I imagine could stand to hurt INTL's top line and margins given the premium they sell for.
      • I highly doubt this clause exists such that a STH home labber running a 900p in ESXi would have their warranty voided.
    (hopefully this is somewhat helpful)

    But what about the p4801x?? Now available on eBay, Amazon and Newegg (to name a few sellers) in m.2 and u.2 at 100gb. Sure there is some performance drop in writes (estimated half of 900p) but pricing is pretty aggressive for those who, so far, have been undecided and wanted plp and higher write endurance.

    Seems Intel has been keen to listen to the pro-sumer market!

    My server has no U.2/M.2 ports. Only AIC will work.
