Poor SSD performance, can't diagnose problem

Hi,

I have a TS128GSS D370 SSD Drive as my main hard drive on a computer, and I'm getting problematic performance (occasional 2-3 second freezes when using Photoshop, sometimes even more).

I ran the windows performance index and got a 5.7 on the hard disk transfer rate test, while the rest of the tests score 7.5 or higher (windows 7). Amazon reviews on the hard disk report 7.6-7.8 scores.

I checked drivers and everything seems to be recognized, I checked HD health with HD Tune Pro and nothing alarming came up. I'm attaching a screenshot of the three relevant screens, but I am currently completely clueless. Does anyone spot anything problematic in the setup? Where should I be looking?

Screenshot

Disk Drives:
- TS128GSS D370 SCSI Disk Device (Primary)
- WDC WD1003FZEX-00MK2 SCSI Disk Device (Secondary)

IDE ATA/ATAPI Controllers
- Intel(R) 9 Series Chipset Family SATA AHCI Controller

HD Tune Pro
- Standard: SATA 3
- Supported : UDMA Mode 6
- Active: UDMA Mode 6

Thanks!

Hey there again, Noam_Tac!

I'd recommend you check the connections to the SSD again and make sure it's plugged in a SATA III (Intel) port on your motherboard. Afterwards, go to BIOS and be certain that you have set the SATA mode for the drive to AHCI. If you need to update that driver, go to the motherboard manufacturer's website and manually upgrade it from there.

This should fix the issue with the system recognizing the SSD as a SCSI.

Keep us posted, though.

Welcome to the TH community, Noam!

I'd strongly recommend you backup all your data from both storage drives somewhere off-site before proceeding with the troubleshooting. Afterwards, I'd advise you check the health section and SMART status of your secondary HDD using the HD Tune utility and also run the QUICK and EXTENDED tests from WD's Data LifeGuard Diagnostics tool. This way you will be able to benchmark the results.

As for your SSD, I'd recommend you check its firmware and make sure it's up-to-date. I'd also advise you to run an SSD-specific diagnostic tool for accurate SMART results.

Another thing you should try is swapping the SATA cables with different ones and check the system performance afterwards. These freezes could be caused by a faulty/under-powered connection to the storage devices. You might as well try booting without the secondary HDD connected to the motherboard and see how the PC will react to that.

Keep me posted with the troubleshooting!

Thanks for the reply, I'm 99% sure that the problem is the SSD and not the WD drive, so I'll look into that.

The health indicators are 100% ok on all SSD health checking apps, but the performance is 6-10 times slower than the benchmark results I see for this hard disk online. (Used AS-SSD to benchmark). Where else can I look?

The firmware is up to date.
Is it bad if the computer recognizes the SSD drive as SCSI? ("TS128GSS D370 SCSI Disk Device" in device manager)
