SSD running hot and write speed slowing down

[smarttt]

Hi,

I've just installed a new Sandisk SDSSDA 120G G26 and performed some speed tests. It's always the same: after 30 seconds it reaches almost 60°C / 140°F (according to SMART data) and slows down significantly (write speed from 350 to 80-100 MB/s). After a recovery time of one minute it's OK again. The read speed is not affected. SMART status is OK.
My other SSDs (two of them also from Sandisk) don't behave like that and maintain a constant write speed.

Is this normal?

Hey there, smarttt.

Is the SSD near a component which could possibly overheat often? Does the case have a good airflow?
I'd say that this is not a normal behaviour. Having in mind that for most HDDs (which are mechanical devices) the maximum allowed operating temperature is 60C°. Having this in mind, plus the inconsistent performance, I'd say that you might have a faulty SSD. It's still worth the try with a different SATA port and cables, or even better - with a different computer, just to see if the same thing happens.

Hope that helps.
