Degrading RAID0 SSD performance?

[themeonster]

When I first bought my G750 JH in October I ran a disk benchmark and it did just over 1 GB/s sequential read and I thought that was pretty amazing. But over time I have periodically run the benchmark and noticed gradually falling scores. Here is the result of today's CrystalDiskMark:



So, I am asking the vast amounts of computing knowledge represented by this forum, how do I get back those lost MB/s? Is there anything else you notice that is off with the posted scores? Any help is greatly appreciated.

Thanks for your suggestion, hmscott after running perfectdisk the speeds are back to normal. I might invest in a full license....

On an unrelated topic, How did you get to have the original SSDs and 1TB HDD and the 840 pro all connected at once?

themeonster, the 1TB is now in an external USB 3.0 2.5" enclosure, and the Samsung 512GB is in Bay 2.

Great score after optimization 🙂

I kept PerfectDisk installed and optimizing. Hopefully it will keep my performance steady over time.

mine is still ..... 840 mb after running disk fragmentation over 10 times.. along with boot defrag

Did you check the model number on the SSD's? Is it the same as mine? Is your partition size up from 96GB to 237GB now?

You don't need to do PerfectDisk disk defrag 10x... just let it run once, and let it run in the background (keep it installed) and it will optimize writes as they happen.

What are your write times? Can you post the screenshot of the CrystalDiskMark run?

Just because I had this same problem, the solution was to merge the 2 ssd partitions into 1, windows recognised the boot C: as an SSD (and not as an HDD as before), and had the system on Power4Gear into High Performance.
