Support PCIe 4.0, continuous read and write performance is up to 7.2GB/s, 6.2GB/s, 4K random read and write performance is up to 1.5 million IOPS, 4K 70/30 mixed random performance is up to 1.8 million IOPS.
512bit random read performance is as high as 4.6 million IOPS, 4K random read latency is less than 6 microseconds, and random read and write latency is less than 25 microseconds.
Additionally, to the read and write performance indicators that make the NAND flash solid-state disk unmatched, the lifespan of the Optane SSD P5800X is also amazing, reaching an incredible 100 full-disk writes per day that is 67% more than the 60 times of the previous generation.
By looking at the comprehensive speed, latency and lifespan, the P5800X series of Optane hard drives are definitely the strongest SSD at present.
The cost will be much more expensive than other SSD hard drives. After all, it is a 3D XPoint memory chip, and the cost is higher than flash memory.
The StorageReview website recently compared its performance with the previous generation of P4800X and DapuStor H3900 hard drives. The latter is based on XL-Flash flash memory and is a special high-performance NAND flash memory that can be said to be the king of NAND flash memory.
StorageReview’s test is more focused on delay, and the following results are not introduced one by one, mainly the delay under different loads.
By looking at the performance, the P5800X has a read speed of 7.1GB/s and a write speed of 5.85GB/s. Except that the write speed is slightly lower than the current high-end PCIe 4.0 hard disk, the overall read and write speed is also very capable.
Well-known the strength of Optane hard drives is latency. StorageReview’s test also deeply reflects this. 4K random reads can reach 1.4 million IOPS, and random writes can also have 1.3 million IOPS.
The delays under different loads are different. However, it did not exceed 100us under the maximum load, and the lowest was only 28us. This is a performance that the other two SSDs cannot achieve.
In short, Intel’s P5800X hard disk is well-deserved as the world’s fastest SSD, which has not taken into account its lifespan against the sky.
P5800X is not without slots, such as limited capacity, and only suitable for expert users-after all, it is not originally intended for individual consumers.
