The OWC Mercury Extreme Pro 6G 120GB SATA 3 SSD Review – Initial Testing

ATTO DISK BENCHMARK V2.46

We can always predict that testing will go well when our first tests exceed the manufacturers specifications as seen here.  ATTO is one of the most popular benchmarks programs for SSDs as it is the test method used by manufacturers to arrive at their listed specifications.  554MB/s high sequential read and 478MB/s high sequential write transfer speeds just cannot be beat from a single SSD.

CRYSTAL DISKMARK VER.3.o (0Fill)

Crystal DiskMark carries the testing one step further by showing us excellent 4k random write scores of 70MB/s and even better 4k-QD32 random write scores of 250MB/s.  The most important of all disk access methods is the 4k random write speeds as they are used in a typical users activities over 50% of the time.  This is a key thing to know if one is considering purchasing an SSD because, in reality, the typical user will use the high sequential read and write speeds less than 1% of the time if ever.

AS-SSD COPY BENCH V. 1.6

AS-SSD Copy Bench is a benchmark that evaluates the time to copy typical files such as an ISO, software program or game.  It provides a result of the maximum transfer speed reached during the copy process as well as the length of time it took to copy the file.  As both the OWC 6G and Vertex 3 utilize the same processor, we thought it might be an interesting comparison. The OWC 6G is shown on the left with OCZ Vertex on the right.

Considering that the Vertex 3 is a 240GB drive in comparison to the OWC 6G which is only 120GB, we found these results to be very close and a great indicator that the Vertex 3 just might be looking at some competition in PCMark Vantage testing.

The SSD Review does not use other components of AS SSD for testing when reviewing solid state drives that utilize compression in their storage techniques.  The reason for this is simply that the software program does not provide an accurate measurement of such drives capabilities and, typically, the consumer becomes confused in wondering why AS SSD results do not match manufacturers specifications.  PCMark Vantage will later be used for such comparisons.

This should have been tested in comparison with a 120GB vertex3 then we would soon see how much better the OWC performs.. Anand tested the 120 vertex3 and it paled in comparison to it’s larger 240gb brother.

If this is true, then the OWC is way out in the lead…. I was thinking to myself the other day, whoever can release a smaller capacity SSDs without reducing performance will lead in the boot disk market.. That’s a big mother of a market waiting to pounce..
