I recently got an OCZ Vertex 4 SSD. I knew they had very poor reputation when I bought it, but I wanted to get a drive with very high IOPS so I bought it anyway.

Sometimes when the drive is under heavy use such as playing video games it disconnects from the computer. I have noticed that it is extremely warm when it does this.

Is this a built in safety feature, or do I have a bad drive?

I cannot find any specifications that say it does, probably defective. – Moab Sep 6 '12 at 1:00
@Moab: I wouldn't assume that. It's not a particularly tough feature to add. Still, my bet would be repeated ECC (Error Correction Code) failures. All flash drives use those (as do harddisks, BTW). There's already a mechanism to detect and deal with them. Disconnecting would be just the last action in the chain of recovery steps. – MSalters Sep 6 '12 at 10:50
@MSalters I did not assume, I said I could not find any documentation to support it. "probably" is not an assumption, but an opinion until someone can change it with documentation that says otherwise. – Moab Sep 6 '12 at 14:23
  • Haven't seen anybody complaining about heating problems on the Vertex 4. You did mention it gets warm, but warm as in what temperature? If it's between 35°C - 50°C, then I guess the temperature is fine.

  • They have fixed some known issues on the firmware, and since you have a problem, please try upgrading the firmware from here.

  • You should also consider using a SSD diagnostic tool to check your OCZ disk. There are many free tools on the web. If there are issues, it will point them out to you.

  • Some guys on the OCZ community have developed some tools for the SSD. You can get some help here too.

  • You may also want to consider diagnosing your OS, or put the drive onto another computer to see if the problem persists.

  • As a last resort you will have get help from OCZ support.
