Intel SSD NVMe Driver
The two most important benchmarks for a drive's performance are speed and latency. These categories are further broken down into sequential and random access patterns. Intel SSD NVMe results represent reading large files such as textures or videos that are stored together. On the other hand, random access represents loading many, typically smaller, discontinuous files such as when launching a game or booting an operating system.
My testing was done on the Z platform with a Core ik. Synthetic tests are typically done by accessing the drive under test from from another drive that you are booted to. Real world tests were Intel SSD NVMe by installing the same Windows installation on each drive and conducting the tests locally.
NVMe SSD Roundup 2018: Intel Optane, WD Black and Samsung 970 Evo/Pro
I used an Intel SSD P as my boot drive for the Intel SSD NVMe tests and also threw its results in for comparison. It is an older drive and represents performance results Intel SSD NVMe previous generation NVMe drives. This gives a good idea of how each drive performs with various files increasing in size from bytes up to 64MB.
Small files are harder to process since there is more overhead for the controller. We can see that the Optane based drives generally Intel SSD NVMe their peak read speeds around k, sooner than the NAND based ones. These are all considered top-of-the-line SSDs and we can see the wide range in their performance numbers. Writing to a drive typically happens less often than reading so manufacturers tend to focus on their efforts accordingly.
The drives here are situated more closely than in the read tests and the gap between the Optane P line and the rest Intel SSD NVMe the drives has widened. I certainly would have expected some better numbers here. The Evo comes in third but gives some very interesting results. On to access time now. These results are important for system responsiveness and when applications need to access many files.
The faster the drive can respond to a request, the faster it can move to the next request in queue. With the exception of the SSD P, all of the results are fairly close together.

The Optane drives do come out on top by a slim margin. Intel SSD NVMe 4K test measures the drive's performance reading or writing a 4K chunk of data.
This is a relatively small file so it is difficult for drives to manage at high speeds. The 4KThrd test measures the drive's performance reading or writing a similar 4K chunk of data, but this time running 64 threads concurrently.

This is also known as a queue depth of The third test I ran was sequential read and write which tests the drive's ability to read or write a single large chunk of contiguous data. The Intel SSD NVMe tests don't really show a clear overall winner but the Pro is the Intel SSD NVMe consistent drive so I'll give it the win here. The WD Black drive leads in sequential writes but comes in 4th at 4K with a 64 queue depth.
Among the top 4 drives, the standard 4K tests are all very close and could be considered within margin of error. Here we see the Optane P drive struggle compared to the rest of the field. The read tests are a little more well defined.
The three Intel SSD NVMe drive destroy the competition in 4K reads coming in at nearly 4 times the performance of the next closest drive. The Optane P also leads in the 4K thread test by a sizable margin.

In terms of pure sequential reads, the Optane drives slow down with the and WD Black drives Intel SSD NVMe and neck for the lead. I'll hand the win for this one to the Optane P given its dominant 4K performance; something that more closely resembles a real world workload. Iometer Benchmark Next up we have Intel SSD NVMe which is an extremely powerful tool and is seen as the industry standard in storage benchmarks. Iometer can measure dozens of metrics, but since we have already covered read and write speeds in details, I will be testing drive response time.
Iometer is also well known for its input-output operations per second IOPS measurement, but that can vary widely depending on the system and configuration. It is also an extremely contrived test that doesn't reflect any workload a user would face outside of high performance enterprise databases. If that is your use case, then there are plenty of drives specifically designed for it Intel SSD NVMe this Intel SSD NVMe won't cover.

- Benchmark Results
I did two tests here. The first one is at a queue depth of 1 which represents the response Intel SSD NVMe for reading a single file at a time.
The second set of tests was at a queue depth of which represents the response time for the drive receiving requests for data at once. Thanks to the design advances of 3D-XPoint, the Optane Intel SSD NVMe really shine here.
