For the long term performance stability test, we set the drive up to run a 20-minute 4K random test with a 30% write, 70% read split, at a Queue Depth of 256 over the entire disk.
In RAID 0, the DCP1000 averaged 207,453 IOPS for the test with a performance stability of 97.08% which you would want and expect from a data center drive.
When the drive is in RAID 1 mode, it averaged 107,252 IOPS for the test with a performance stability of 71.3%
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
