M.2 SSD REPLACEMENT AND HYBRIDISK INSTALLATION
Looking at our system in its pre-configured state, we might suggest that this is typical pre-configured laptop performance, thus wanting to build a better machine. As we two MyDigitalSSD Super Cache 2 M.2 SSDs (64 and 128GB), we thought this the ideal opportunity to see just how much we could improve the system, all the while maintaining the pre-configured OS and data that was their prior.
The bonus here is that FNet HybriDisk Caching software is included with the purchase of the MyDigitalSSD Super Cache 2 SSD, and also, MyDigitalSSD marketing reps had been bragging to us for some time that HybriDisk was as close as we were going to get to performance similar to what we saw with NVELO Dataplex some time ago.
Replacing the M.2 SATA 3 SSD was a matter of removing a screw and switching SSDs, exactly the same as it would be for a mSATA form factor. Installation of FNet HybriDisk was a matter of downloading the software from MyDigitalSSD and following their instructions. KEY POINT! Ensure on your installation of HybriDisk that ‘Maximized Mode’ is selected. If it is not, you will have substandard SSD write performance from the software.
HDD AND SUPER CACHE 2 SSD RAW PERFORMANCE
The best way to identify any performance increase would be to know the true speed of the hard drive, before caching, as well as the SSD. Only then can we determine how close to true SSD speeds HybriDisk can get us. Checking the performance of the Seagate HDD once again, performance hasn’t change with read and write speeds of the hard drive just over 100MB/s. These ATTO and Crystal DiskMark result depicts the new MyDigitalSSD Super Cache 2 64GB SATA 3 M.2 SSD performance in our Test Bench:
We think transferring incompressible data has a bit of an impact as we see write performance of Crystal DiskMark drop below 1/2 of the 374MB/s high of ATTO Disk Benchmark. Conversely, high sequential read performance of 523MB/s is a great performance benchmark for such an SSD.
FNET HYBRIDISK ENABLED
These tests demonstrate the performance of the hard drive with FNet HybriDisk and the tests were conducted immediately after HybriDisk was enabled:
By comparing the benchmarks of the SSD alone above to that of the hard drive when cached with that SSD below, we can see that HybriDisk has accomplished what only Dataplex had done prior, almost equalling the SSD performance in HDD caching.
