Relatively good speed, poor temperature

So SSHD is supposed to combine the capacity of an HDD, the speed of an SSD.
Well, for Speed: (I have a screen shot attached to a benchmark)
Compared to a HDD the lower values ​​of small files are really good. The speed reaches the SSHD at a 2KB large file, just my old HDD only at a 64KB large file. So it's a really good performance enhancement, but only in these small files to 64KB, Larger files provide the same speed as a normal HDD. But this is indeed in the nature of an SSHD, the 8GB flash memory offer so enough boost for a large number of small files.

Compared to my SSD from Kingston (300V) it provides even better performance in this amazing small areas. But my SSD delivers even at 8KB 150% of the performance, with 150-180 MB / sec, up to 550MB high / sec for large files from 128KB.

But what does not go at the temperature development ... After an hour copying the SSHD already reached 51 ° C
My SSD and HDD are here at 33-39 ° C over 40 ° C do you get by some manufacturers an expected survival of only 50% optimally are here just below 40 ° C which is why I would recommend the hard disk can not include sensitive data ... As a pure program and operating system disk, you can use them to hire.
