I recently built a new system and decided to use Mushkin Chronos 240 gb x2 in raid 0. Once I had the system build and running I noticed it was running really sluggish some examples are long load times for different games and a very long boot time. After some research I decided to use crystal disk mark to find the speeds of my drives. The speeds I got were shocking

Sequential Read was 80.9 mb/s
Sequential Write was 79.8 mb/s

That's not even in the ballpark of the usual speeds I see everyone posting for the ssd's. I have tried reinstalling the OS, I ensured I had every possible driver up to date. I'm even about to get parted magic so I can update the firmware while they are in raid 0. As soon as the OS is done installing I'll benchmark with ATTO. I'm just looking for help with trouble shooting!

My Whole System
Mobo: MSI Z87M Gaming
GPU: Gigabyte GTX 770
Memory: Mushkin Enhanced Stealth DDR3 2800 2x4gb
Cpu: Core I7 Haswell 4770k
HDD: Western Digital Black 1TB
SSD: Mushkin Chronos 240gb x2

Edit 1: I redid the Crystal Disk Mark these are the speeds I got

* MB/s = 1,000,000 byte/s [SATA/300 = 300,000,000 byte/s]

Sequential Read : 72.226 MB/s
Sequential Write : 44.613 MB/s
Random Read 512KB : 55.389 MB/s
Random Write 512KB : 44.951 MB/s
Random Read 4KB (QD=1) : 2.064 MB/s [ 504.0 IOPS]
Random Write 4KB (QD=1) : 8.158 MB/s [ 1991.7 IOPS]
Random Read 4KB (QD=32) : 20.132 MB/s [ 4915.0 IOPS]
Random Write 4KB (QD=32) : 30.973 MB/s [ 7561.6 IOPS]

Test : 1000 MB [C: 7.0% (31.2/447.1 GB)] (x5)
Date : 2014/02/02 13:00:13
OS : Windows 7 Home Premium SP1 [6.1 Build 7601] (x64)

Edit 2: ATTO Bench test now added.

Hi,

Your screen shot of ATTO did not attach for some reason.

have you updated to the latest BIOS for the mobo?

Oh wow, the screen shot didn't attach... Well, I'll have to wait until later to try and get it to post. I did however ensure that the mobo bios were up to date. After I reinstalled the OS yesterday I had the same speeds I have been getting. I'm going to attempt a secure erase and see if that may be my problem.

Also, I will be attempting the drives in another system soon to see if I can pinpoint the problem...

On another note. I got parted magic working and went to update the firmware, but the software didn't pick up any of the drives, but when I go to do erase disk they are there.

What were the max read speeds in ATTO?
If they are really low I would think something else is going on.

What version of Parted Magic were you using?

I am using the newest version of Parted Magic. The free one you posted a link to is no longer up. I think you are right it is something else going on as far as the problem at hand is concerned. I finally got the system back up and going and ran tests on all the hard drives and ssd's I have. They all came back with really low speeds. THe raid0 Chronos I have came back in ATTO with 120mb/s at 8192 read and write. So, I'm not sure at this point what the problem really is. I assume it has to be the sata controllers, but you know what they say when you assume something...
