To test real life performance of a drive we use a mix of folder/file types and by using the FastCopy utility (which gives a time as well as MB/s result) we record the performance of drive reading from & writing to a 256GB Samsung SSD850 PRO.
100GB data file.
60GB iso image.
60GB Steam folder – 29,521 files.
50GB File folder – 28,523 files.
12GB Movie folder – 24 files (mix of Blu-ray and 4K files).
10GB Photo folder – 621 files (mix of .png, raw and .jpeg images).
10GB Audio folder – 1,483 files (mix of mp3 and .flac files).
5GB (1.5bn pixel) photo.
The DCP1000 is much more adept at handling larger files than the small bity files of everyday office use in both RAID 0 and RAID 1.
Just to see how fast the drive could transfer files we tested transfers from folder to folder on the drive. Once the SATA interface of our usual Samsung transfer drive was out of the way the drive really showed its muscle in RAID 0 but once again only on large file sizes. Our 100GB data file was moved between folders at 2,572MB/s or give to a better idea it took just 39.8 seconds to do it. The 5GB photo took 1.7 seconds and the BluRay movie a mere 17.5 seconds.
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
