Intel Optane 800p & 900p review: 3D XPoint for the regular consumer!

Extreme performance at an extreme price

AS SSD

AS SSD works with uncompressed data and performs both read and write tests. Testing begins with 4 kB data blocks, with one instruction at a time, and then with 4 kB data blocks with 64 simultaneous instructions. Finally, a sequential read/write test is also carried out, which provides a measure for working with very large files. AS SSD also determines a total score on the basis of all the tests. Although the tests largely overlap with the Iometer tests, we run AS SSD because you can also easily run this benchmark yourself (download link) in order to make a comparison with your own SSD.

Based on all of the different tests AS SSD produces total-, read- and write scores. 

The top of the graph that shows the results of AS SSD is all red at the top - the Optane 900p SSDs appear to perform even better than the data center variant we previously tested. All variants score more than 10,000 points: these scores are truly unprecedented. The 800p 120GB is stuck on on more than six thousand points which makes it slower than the Optane DC 4800X; the 60GB version even has a lower score than some of the Samsung SSDs with regular nand.

Looking at the underlying scores we can see that the Intel Optanes (especially the 900p) score very well in the read tests. The write speeds of the 900p are good but special, while the 800p scores relatively bad in that respect. Also note that the Optane 480GB is significantly faster when writing compared with the two smaller models.

  • Total score
  • Read score
  • Write score

The underlying read tests are sequential read, reading 4k data blocks at random with 1 or 64 at the same time and the average access time.

Especially the results with small files appeal to the imagination, although the access time is also faster than many competitors.

  • Sequential
  • 4k (1 thread)
  • 4k (64 thread)
  • Access time

The underlying write tests are sequential write, writing 4k data blocks at random with 1 or 64 at the same time and the average access time.

The Optane 900p always shows good performance in the write benchmarks, but does not manage to form a league of its own as it is able to do with the read tests. The 800p performs poorly.

  • Sequential
  • 4k (1 thread)
  • 4k (64 thread)
  • Access time
