Terrible SSD performance

This... Eliminate the the PC first before you troubleshoot in depth. You may have a dud SSD..
Out the box all SSD's perform very well.

Try it in another PC to eliminate your PC as an issue but starting to sound like a dud. It happens ...

Well, just tried the SSD in another machine, can confirm it's working fine, over 500MB/s read rates.

Now if only I could figure out what is wrong on my board.. :(

Time to Google your mobo ...
 
So here's an odd thing, I plug the drive into an external housing which connects via eSATA, plug that into my pc's SATA port and suddenly it runs fine apart from the fact that it gets limited to SATA II for some reason and that the installed OS's don't wanna boot off that. But still accessing it I can get around 250MB/s like that.

I see your ssd has an in-house Transcend controller.

Transcend doesn't make their own controllers, they license them from other vendors like LSI or Phison.

The problem is with your SATA ports then. eSATA on Z87 boards takes one SATA port from the front of the board and moves the PCI lane allocation to the eSATA port.

I'd do a BIOS upgrade/downgrade as well and contact the shop you bought it from to see if they have any solutions for you. Otherwise, if you want, you can go straight to the distributors, which will be either Corex or Pinnacle Micro.

So in my latest experiment I pulled the SATA controller card out of my server 'NAS box' (LSI 9211-8i) and installed that in my PC, now when I used my SSD on that server PC with that same SATA card it runs perfectly, but on my PC it has exactly the same performance trouble as with the onboard SATA ports. It seems to me that there must be something more related to my PC, perhaps because it's the 1150 architecture? Can that be? :confused:
 
Well I eventually fixed this issue by returning the drive (the only advice Transcend would give me) and buying a different brand. I have a Crucial MX100 now and it's running 100%. :)
