Performance Tests

For these performance tests we hook it up to the Intel 6G SATA controller for consistencies sake.



CrystalDiskMark is a tried and true method of testing, accepted nearly everywhere as a general means of understanding performance. The WD Blue SSD at 1TB does a good job of keeping up with it’s more expensive sibling, It’s within only a few MB/s, even at 4K. In fact, random transfers are looking rather good, though are by no means the fastest available. But at 4K, random reads and writes are very competitive.



For this test we chose to use IOMeter due to the fine grain control you can have over the entire test. It ends up being a most impressive and very complex test. We set this to the most difficult QD that you might encounter to show a worst case scenario. As expected, the WD Blue SSD can’t quite keep up with the Extreme Pro, though the number of IOPS at 4K is rather good, considering the price. In fact, even compared to the IOPS efficient Samsung 850 Pro, this is still really good.

Response Time


Next we’ll measure response time, or the time it takes for a request to do something on the disk is acknowledged. For this we use HD Tune Pro again as the tool of choice to see just how long it takes to actually begin a task. We see that it’s slightly less responsive, though given the price differential, such divergence is expected.

Massive Transfer Test


The next test is a homemade test where a massive mixed-file folder that’s 33.8GB in size is transferred from one to the other. I’ve used HD Tune Pro to measure the results, including the time it takes to transfer the folder, the average IOPS during the transfer and, of course, the transfer speed itself. This is a write-only test. It’s a static Steam game folder that’s been placed elsewhere precisely for this test. It isn’t updated, so it can be used as a point of comparison in the future. This is a good test, primarily because it’s a real world transfer test you might encounter in real life. Such as when you pop this bad boy, or any new drive, into your system and start transferring your stuff over. Quite the showing and one that’s likely in line with the similarly equipped SanDisk X400. It doesn’t break any speed records, but it’s an SSD and behaves like one.
