WD Blue SSD Review (1TB) – WD Steps Into The Ring

PCMARK VANTAGE X64 HDD SUITE

The SSD Review uses benchmark software called PCMark Vantage x64 HDD Suite to create testing scenarios that might be used in the typical user experience. There are eight tests in all and the tests performed record the speed of data movement in MB/s to which they are then given a numerical score after all of the tests are complete. The simulations are as follows:

  • Windows Defender In Use
  • Streaming Data from storage in games such as Alan Wake which allows for massive worlds and riveting non-stop action
  • Importing digital photos into Windows Photo Gallery
  • Starting the Vista Operating System
  • Home Video editing with Movie Maker which can be very time consuming
  • Media Center which can handle video recording, time shifting and streaming from Windows media center to an extender such as Xbox
  • Cataloging a music library
  • Starting applications

PCMARK VANTAGE RESULTS

During the WD Blue’s PCMark Vantage run it achieved a total score of nearly 75K points. Most results were in the 300-400MB/s range in this test. The best result of 430MB/s was during the Windows Media Center benchmark while the worst of 268MB/s was during the adding music to Windows Media Player benchmark.

PCMARK 8 EXTENDED STORAGE WORKLOAD CONSISTENCY TESTING

For our last benchmark, we have decided to use PCMark 8 Extended Storage Workload in order to determine steady state throughput of the SSD. This software is the longest in our battery of tests and takes just under 18 hours per SSD. As this is a specialized component of PCMark 8 Professional, its final result is void of any colorful graphs or charts typical of the normal online results and deciphering the resulting excel file into an easily understood result takes several more hours.

There are 18 phases of testing throughout the entire run, 8 runs of the Degradation Phase, 5 runs of the Steady State Phase and 5 runs of the Recovery Phase. In each phase, several performance tests are run of 10 different software programs; Adobe After Effects, Illustrator, InDesign, Photoshop Heavy and Photoshop Light, Microsoft Excel, PowerPoint and Word, as well as Battlefield 3 and World of Warcraft to cover the gaming element.

  • PRECONDITIONING -The entire SSD is filled twice sequentially with random data of a 128KB file size. The second run accounts for overprovisioning that would have escaped the first;
  • DEGRADATION PHASE – The SSD is hit with random writes of between 4KB and 1MB for 10 minutes and then a single pass performance test is done of each application. The cycle is repeated 8 times, and with each time, the duration of random writes increases by 5 minutes;
  • STEADY STATE PHASE – The drive is hit with random writes of between 4KB and 1MB for 45 minutes before each application is put through a performance test. This process is repeated 5 times;
  • RECOVERY PHASE – The SSD is allowed to idle for 5 minutes before and between performance tests of all applications. This is repeated 5 times which accounts for garbage collection; and
  • CLEANUP – The entire SSD is written with zero data at a write size of 128KB

In reading the results, the Degrade and Steady State phases represent heavy workload testing while the recovery phase represents typical consumer light workload testing.

PCMARK 8 RESULTS

As you can see, performance is recorded in terms of Bandwidth and Latency. Bandwidth (or throughput) represents the total throughput the drive is able to sustain during the tests during each phase. Latency, at least for the purposes of PCMark 8, takes on a different outlook and for this, we will term it ‘Total Storage Latency’. Typically, latency has been addressed as the time it takes for a command to be executed, or rather, the time from when the last command completed to the time that the next command started. This is shown below as ‘Average Latency’.

PCMark 8 provides a slightly different measurement, however, that we are terming as ‘Total Storage Latency’. This is represented as being the period from the time the last command was completed, until the time it took to complete the next task; the difference of course being that the execution of that task is included in ‘Total Storage Latency’. For both latency graphs, the same still exists where the lower the latency, the faster the responsiveness of the system will be. While both latency charts look very similar, the scale puts into perspective how just a few milliseconds can increase the length of time to complete multiple workloads.

For a more in-depth look into Latency, Bandwidth, and IOPS check out our primer article on them here.

AVERAGE BANDWIDTH (OR THROUGHPUT)

These results show the total average bandwidth across all tests in the 18 phases. In this graph the higher the result the better.

AVERAGE LATENCY (OR ACCESS TIME)

These results show the average access time during the workloads across all tests in the 18 phases. In this graph the lower the result the better.

TOTAL STORAGE LATENCY

These results show the total access time across all tests in the 18 phases. In this graph the lower the result the better.

WD markets this drive as being able to withstand heavy workload use cases in terms of endurance. In our extended PCMark 8 testing also proved to do fairly well in terms of its performance in both latency and bandwidth. It maintained a low average and total latency profile. It averaged 200Mb/s bandwidth during the recovery section. The heavy workload consistency was fairly good, but it excelled during the recovery phase where its performance was nearly perfect. When compared to the many other TLC based SSDs in the market the WD Blue seems to hold its own.

Been so quiet thought you’d all gone on holiday together.
WD will need to learn the SSD pricing game really quick.

Wonderful to see someone else reaching 10K-4K iops.
thro in other reviews it’s all over the place-Crystal 10K+
AS-SSD 7K7 and Anvil 7K9………………………….
Be interesting to see how smaller drives go…………….
EDIT
as to your surprise how well this drive performed fol planer TLC.
Thro Sammy were first out the door-we all know the problems
the 840 series had.And Crucial’s BX200 sits just above the lemons.
Sandisk produced a good midrange drive with the Ultra2 quite a while ago.

c’mon, 2d tlc needs to die quick. 3d tlc can’t come soon enough for budget drives.

I came across this file transfer tool called Binfer. I have used Binfer to transfer large files with Binfer several times and recommend it highly. It does require the senders computer to stay online.
