View Full Version : Degrading RAID0 SSD performance?

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:

36083

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.

You don't mention if you manually run TRIM, or have a schedule set up to run it on a regular basis...

36085

If you haven't run TRIM, do it now on the SSD partitions, then reboot and re-run CrystalDiskMark.

Check to make sure Optimize see's the SSD as an SSD, and not a HD.

If Windows thinks the SSD is an HD, run a cmd shell window as Administrator, and run this:

winsat formal <== let it finish, then reboot

Then run optimize now that the SSD shows up as an SSD.

Let us know how that works out :)

Thanks for the quick response. I have windows set up to run TRIM on a weekly basis. And windows has already recognized it as an SSD.

36086

I did manually run TRIM and reboot and the numbers improved slightly but not to where they were.

Two things to try. Get a real defrag / optimization program and let it loose on the SSD RAID0 :)

It will add GB to throughput counter, but it worked for me.

Next best, better but more of a pain, back up your stuff and break the RAID0 and remake it from the BIOS. Then use your Asus Backtracker USB 3.0 recovery flash drive to restore to the new RAID0. I got back all my performance that way :)

Is this really true nowadays? I don't use any of my SSD'S in an array (though I have several arrays using mechanical drives), but my understanding was that defragging SSD's has little tangible benefit and could actually do damage since most modern SSD's do some form of wear leveling.

Off to do a little research.....

Nillaz, I tried and purchased Raxco PerfecDisk Professional 12/13 Windows 8/8.1 and it worked great, but it takes a lot of writes to complete, so next time I moved to a RAID0 rebuild and restore, which got me even more throughput and is still running fast several months later.

Cool, good to know for when I eventually start replacing my mechanical drives with SSD's.

I hadn't reinstalled PerfectDisk since switching back to the RAID0 boot from the Samsung 840 Pro 512GB, so I checked and my performance had dropped to 875MB/520MB (sorry, didn't screenshot the results).

I installed my licensed copy of Raxco PerfectDisk, took the default config it came up with, and optimized the RAID0 using SmartPlacement Classic, the C drive, followed up with a boot defrag, and ran CrystalDiskMark, and now I am back to 1025MB/598MB

how did you get such good score? I have same defrag software as you ;) and i did everything you did, including boot files, and i get a slower read, or is your SSD just faster one? lol If it is then ok, otherwise i want it fixed XD

HomieOC, you have a 2 x128GB RAID0, right? But it looks like you left your default partitioning, I combined partition's so I can have more contiguous space. IDK if that is the only thing that makes my score higher, but you can give it a try. My C partition comes out at 237GB now, and yours is at 96GB.

36105

My D drive is now my Samsung Pro 840 512GB, here is it's score for comparison:

36106

And, here is the drive make/model info, to compare against your 128GB model numbers

how do i combine my parition?

also.. by looking at image below.. can u tell wheter i have 2 128 gb SSD? Or is it 1 256 gb SSD with 2 partitions? Also, isn;t trim no long available if i combine the two?

You need another tool to see beyond the RAID0 volume. Storage manager works with Volumes presented to Windows.

I used HWinfo64 for the drives screen grab I posted above.

You need to do a couple of things before deleting then combining the free space left by the F and Recovery partitions to make a bigger C partition.

Asus Backtracker - use a USB 3.0 drive, at least 16GB
http://www.asus.com/supportonly/ASUS%20Backtracker/HelpDesk_Download/

First, because you are going to delete the F partition you need to back up the data you have on the F partition, and Second because you are going to delete the Recovery partition you need to make an Asus Backtracker flash drive recovery.

The Backtracker flash drive recovery will let you restore your laptop drives to their original configuration. Don't forget to pull out your 1TB drive before doing a restore, as the partitions on the 1TB drive will also be redone along with the RAID0.

After doing the backups, you can use the Windows Storage Manager to delete the 20GB Recovery Partition, and then delete the F partition, and then right click on the C partition and Extend Volume to add the free space - take defaults and Apply.

Then reboot and you have combined the free space from the two deleted partitions into the C drive, like mine. You can run trim on it again, and reboot - then run the CrystalDiskMark again :)

i already jhave a USB backup of my partition :D and i only have crysis on f drive.. but i still dont know how to partition lol and puit them together, and i dont understand why i have to remove my 1 tb hardrive from my laptop

hmscott meant to pull the 1TB HDD only if you ever need to restore your laptop from the backup. If you go to disk management and right click on the partition labeled F:, there should be an option to delete it. It might have to be empty. The suggestion to delete to recovery partition is not essential however, the extra 20 GB does help with the small size of our OS drives. If you have trouble deleting the partitions try this:
http://social.technet.microsoft.com/Forums/en-US/4f1b84ac-b193-40e3-943a-f45d52e23685/cant-delete-extra-healthy-recovery-partitions-and-healthy-efi-system-partition?forum=w8itproinstall
Just be very careful as a simple mistype with that method could very easily break your system and require you to start from scratch.

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.

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.
