Optane 900P vs. 960 EVO NVMe M.2 250GB SSD https://ark.intel.com/fr/products/123623/Intel-Optane-SSD-900P-Series-280GB-2_5in-PCIe-x4-20nm-3D-XPoint http://www.samsung.com/fr/memory-storage/960-evo-nvme-m2-ssd/MZ-V6E250BW/ Random reads are significantly lower for the M.2. especially in this capacity range. The larger M.2. drives get better performance but still fall short of the Optane 900p in every way, performance and reliability. And since Intel makes the processors, they also optimise the internal bus instructions and transfers. This has the effect of reducing access times in fully virtualised environments. These are the big differences on the points you can compare. Knowing your hardware, motherboard, processor, ram is very important when choosing disks if you want full performance optimisation.

Instead of asking the same question again, can you wait until the first question has been answered? The questions are there precisely so that the same question doesn't have to be asked several times... The question has been answered by digitec in the meantime: https://www.digitec.ch/de/s1/QuestionAndAnswer/ist-hier-die-star-citizen-promotion-sabre-raven-ebenfalls-enthalten-die-intel-seite-gibt-keine-genau-80899

Unfortunately, this offer has come to an end.

Compared to a Samsung 960 Pro, the Optane packs a good portion of IOPS on top. Optane: 550,000 IOPS (random read) 960 Pro: 330,000 (512GB) or 440,000 IOPS for the 1 and 2TB versions. Taken from the specs on the manufacturer's website. Whether this is "unnecessary" is up to each individual to decide.
