PNY CS2211 SSD Review (240GB/480GB)


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



PNY XLR8 CS2211 240GB PCMark Vantage

480GB PNY XLR8 CS2211 480GB PCMark Vantage

PCMark Vantage gives us our first glimpse at real world performance. Both capacities performed very well in PCMark Vantage with scores averaging 83K. Performance across all tests is solid with the lowest speeds just dipping down to the 300MB/s range during the Windows Media Player and Movie Maker tests. This is great to see. Let’s move on to PCMark 8 to see how these drives handle our torture 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.


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.


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



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.



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


In our PCMark 8 consistency testing the PNY CS2211 SSDs do very well. As we can see, performance is on par or even better than some of the popular mid-tier SSDs. Under heavy workloads it does well, consistency is much better than most other options, but it still cannot compete with the SanDisk Extreme Pro or OCZ Vector 180.  When it comes to light workload performance in the recovery phase we can see that its performance keeps it in the ranks of other mid-tier SSDs again. What we find interesting is that this drive edges out head of the Kingston HyperX Savage by about 40MB/s during the final phases and has slightly better latency results with this newer and smaller nm NAND.

    G’day Sean

    Seems the same Phison made drive with 19nm flash is faster,

    and possibly cheaper………….,4397-3.html

    Glad to see reviews again instead of announcements. But It amazes me how these companies advertise their new ssds with so much enthusiasm, when there new ssds are slower than the previous generation. It’s like, yeah we shrunk the nand size again, Woopie!!! And now it’s a little slower but almost as fast.

      As long as it performs adequately and the endurance/retention is reasonable, there is nothing wrong. After all, each generation is getting cheaper.

    Does this performs better that Samsung 850 Pro and Crucial M550? I am lost which to choose…

    Ugh, all the graphs have two SSDs using the white line. which one is which ?

    You say this is a TLC Nand but the official website says its an MLC I am going crazy here. Anandtech also says its an MLC.
    Well I am going crazy cause many people are saying that TLC drives come in 120/240 capacities and only the MLC come in 128/256 and so on capacities.
    I have seen uptill now two brands that have the 120/240 capacites but claim to be MLC one is PNY and the other is Chiprex. So I am confused. These are really cheap but I don’t want it if its a TLC Could someone please confirm

      TLC -is- MLC

      MLC = Multiple-level cell
      TLC = Triple-level cell

      Multiple means more than one.. 3 is more than one.

      MLC usually means 2 levels per-cell, but manufacturers can sometimes label TLC as MLC.
