In our sustained Sequential reads versus block size test, once again the drive produced figures exceeding the official ones in RAID 0, ending the test at 7,284.14MB/s. In RAID 1 the drive peak drops to 5,871.62MB/s, still a very impressive figure.
When it comes to writes, in RAID 0 the drive peaks at 6,202.29MB/s at the 64K block size, again faster than the official figure before falling back to 5,027.52MB/s at the end of the test. In RAID 1 the writes drop considerably ending the test at a peak of 1,718.32MB/s. It may be a lot slower than RAID 0 but the performance is more stable throughout the test.
Would it be possible to do game load times in benchmarks? Some engines, e.g. Frostbite, REDengine, RAGE, are extremely impacted by SSD/HDD performance so it’d be great to see how much of an impact such a product has on loading times.
What is the MTBF for this drive? Given the read write times. Normal day to day and say video editing on a daily basis?
“Stated endurance for the 1.6TB drive as a whole is 1820TB TBW with each of the 400GB drives rated at 375TB TBW”
Depends how much you write per day. 100GB/day would give an estimated 18200 days. 1TB/day would give an estimated 1820 days.
I’ve got a 950 Pro for close to 2 years, that’s now hit 40TB written (rated 400TBW), it’s used as a buffer drive for recordings, temp drive, and to store games on.
I’ve also got a 960 Evo, had it for about a year, is only used for OS and smaller apps like office / photoshop etc, that’s now at 6.8TB written, (rated 100TBW).
Edit: also both drives have only gone down to 99% drive life remaining according to SMART, despite having used 10% and 6.8% of their rated writes. Google the ssd endurance test, some drives almost made 2000 TBW before failing outright, and thats a few years old.
Edit edit: have a look at this;

That would be interesting to see, especially with comparisons against other drives in similar raid arrays as this raid on card
