I recently bought Asus S550CM VivoBook laptop. It includes 24GB SSD disk (used for cache) and 1TB sata HDD. It comes with Windows 8 preinstalled but since day 1 everything was not working fine. Since computer also comes with 8GB of ram and i7 CPU I would expect way better performance.
After blaiming it on preinstalled Windows I formatted everything and made a clean install - it wasn't any better. Afterwards I tried installing Windows 7 and it started to work even worse.
Then I started to investigate the computer and found out that SSD disk is performing very poor and after making a benchmark using HDTune I discovered that speed fluctuates all the time! While speed of sata drive is almost constant (about 105 MB/s) the speed of ssd drive fluctuates from 0 to 250 MB/s all the time.
During the last benchmark which you can find here:
The speed did never rise above 115MB/sec. I am also getting errors that disk temperature is too high:
Any suggestions? Is this a hardware failure? How can I check what is going on (or whether it is just a software/misconfiguration issue) by myself before returning this laptop to customer service? I really want to try everything before bringing it back because this would mean that I would be without it for quite some time (not to mention time needed to backup and restore everything I configured).
