HD Tune is a Hard Disk utility which has the following functions:
Benchmark: measures the performance
Info: shows detailed information
Health: checks the health status by using SMART
Error Scan: scans the surface for errors
HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.
Before you close this review and thinking that we've made an error or that Vertex 4 is a dog, let's talk about what is going on with the sequential reads. In our testing we found that the single queue depth read on both Vertex 4 models we have in-house is right around 200MB/s. We've confirmed the result with other reviewers who have the Vertex 4 in-house for testing as well. We confirmed the results a couple of different ways on our end. The easiest way for you to do this at home is to simply cut a movie or other large file from Vertex 4 and paste it onto another fast SSD with high write sequential write speeds. We used a Plextor M3 Pro 256GB.
Here is the interesting part. With one file we achieved right around 190MB/s transfer, but with two files in different transfers the number doubled. With three files in different transfers the performance was a hair over 500MB/s when we added the combined transfer speed number together.
This is obviously going to play a significant role in your purchasing decision, but so will other factors as well that we'll look at today. We'll going into a lot of detail about real-world use in the final thoughts and our findings based on three days of actually using Vertex 4 as a boot drive in a system here at the office.
Vertex 4 has a very high sequential write speed, but as we noted on the specifications page, write performance varies by drive capacity. The 256GB Vertex 4 sits in a sweet spot for price and capacity so we'll start there. With a sequential write of right around 360MB/s average with compressible data the 256GB model Vertex 4 is a little slower than Vertex 3. This test only measures compressible data, something to keep in mind. We'll look at incompressible data in a couple of pages.
The 512GB Vertex 4 is a different story. With a 410MB/s average write speed, this model bests every other 2.5" form factor drive we've ran in this test.
At this time I'd like to point out some changes that were made to our benchmark results charts. With a new push towards high IOPS on all of the new SSDs coming out in 2012, we've replaced our aging Vertex 3 drives (120GB and 240GB) with Vertex 3 Max IOPS models. To compare the new flagship Vertex 4 512GB to an equal SandForce based drive we've also added a Vertex 3 480GB drive.
