Toshiba XG6 1024GB NVMe SSD Review

So where does the Toshiba XG6 sit in our summarised view of the latest NVMe drives that we have reviewed in recent months –

NVMe drives Comparison Summary

The summary includes the following factors:

  • The best price for the nearest to 0.5 TB version of the drive, as found on or at the time of publishing (Samsung 970 EVO 500GB – £149.99, Adata SX8200 480GB – £116.52, Corsair MP300 480GB – £134.98, Toshiba OCZ R100 480Gb – £155.23) converted to a price per GB.
  • Endurance – the amount of data that can be written to the drive within a 5 year period and for the drive to remain in warranty, stated as the number of GB that can be written per GB of the drive’s user capacity. So, for example, the Samsung 970 EVO 1TB is warranted for 600TB of writes and the GBs that can be written per GB of user capacity is 600,000 / 1,000 = 600GB.
  • The Sequential Writes and Reads and Random 4K Writes and Reads results from our OakGate FOB Tests
  • The PCmark8 ‘Real World’ Storage Benchmark score
  • The Anvil Synthetic Benchmark score

We don’t yet have values for price or endurance for the Toshiba XG6.

The best result for each factor is highlighted in green.  Other drives will be added to the NVMe Comparison Summary as we move forward.

Some observations on the Comparison Summary to date –

The Corsair MP300 and the Toshiba OCZ RC100 are 2 lane drives (2 x PCIe 3) whereas the others are 4 lane, so they are expected to have lower performance.

Top scores in performance benchmarks are now being shared by the Samsung 970 EVO, The Adata SX8200 and the Toshiba XG6.

It’s interesting to note that the difference in the PCMark8 Storage benchmark results is marginal and this suggests to me that the user experience to be gained from each drive would be very similar – or to put it another way I very much doubt that a user could tell the difference.

Once again (as I did for the Toshiba RC100) I commend Toshiba for the XG6’s outstanding power efficiency, which will make the XG6 an excellent choice for use in a laptop.  I was also very pleased with the XG6’s post trim recovery.

The Toshiba is clearly an outstanding performer.  Prior to the retail launch if you find your new laptop has an XG6 onboard you should be very happy.

If Toshiba can hit an excellent retail price point with the use of their 96 layer 3D NAND then I am confident the XG6 will be a great success.    

I am pleased to award the Toshiba XG6 our highest rating of ‘Outstanding’.
