Arne,

I thought we'd move here as we were off topic. I'm running the trial version of Stellar Smart. It reads both disks OK. The temp of the 250Gb Seagate Barracuda starts at 24C and levels off at 37C even after 6hrs. The SSD has no temp readout, it doesn't get warm.

Running Roadkil's Disk Speed test I get a max speed of 160MB/sec for the SSD (varies slightly with the block size) which agrees roughly with the makers figures of 150MB/sec. They also quote the same figures for MLC & SLC via a SATA2 interface. You would need some form of DMA interface to make use of the very expensive SLC drives. The Seagate only makes 72.4MB/sec max thus confirming my subjective impression of faster boot-up, shutdown and general use.

I use a separate machine for receive, an older model but ticks along happily.


Cheers, Guy

Hello Guy,

Although speedtesting software can be fooled by ramdisks and fast SSDs, you could try the free versions of HDtune and HDtach.

HDtune will also read temperature and other SMART parameters.

If the SSD performs well you could place Tellicast's *.fsy files on it to get more free ram.

Greetings,
Arne
