We’ve had some people ask for AIDA64 linear write tests to be done, so we fired that utility up to see what would happen.
When you take a look at extended sustained write performance you’ll see that the performance was fairly smooth at the start and then once the drive was almost 30% full the performance dropped. Performance was right around 610-615 MB/s at the start and then dropped to around 540 MB/s for the remainder of the test. The peak write speed seen was 615.6 MB/s with the low being 489.1 MB/s. It took 7 minutes and 11 seconds to completely fill this drive and the average speed was 565.6 MB/s.
The performance drop was unexpected, but was likely due to the fact we had another utility open to monitor drive temperatures. We’ll go back and re-test at a later date.
Before we wrap things up we wanted to see how real-world was when writing a movie folder containing seven 1080P movies over to the SSD. For this test, we are going to simply stress write performance by transferring over a 30.6GB folder of movies off of a PCIe NVMe SSD to the drive being tested to see how performance looks.
The Intel Optane SSD 800P 118GB finished this test with a speed of 558.5 MB/s. No where near the blistering 1479 MB/s seen on the Intel Optane SSD 900P 480GB, but still faster than any SATA III SSD. It would be nice to see sequential write speeds a little faster on the 800P series as budget PCIe NVMe drives like the DREVO ARES 256GB drive are able to beat it by a fair bit and cost half the price and have higher storage capacity. The Random Read/Write performance is amazing on the 800P series, but it feels like a normal SATA III SSD when you are moving around large game, movie or audio directories.
We’ll talk more about that in the conclusion on the next page.
