Okay, thanks everyone. I don't have a spare disk-slot on this system nor the time to experiment with this, so I'll just have to live with it :-)
There are also hybrid disks, rotating plus small ssd, in the same enclosure. The ssd acts as a big cache of the magnetic media. I believe these are firmware implementations, transparent to the operating system (only one SATA port). There is also a technology, used on some Windows laptops, combining an SSD and HD in a similar manner (two SATA ports), but controlled by the operating system, which can thus decide what to cache on the SSD. Windows places there the files used for boot, for instance. I believe everything is eventually written to the HD, too. I never remember the proper name of this technology. I think it comes form Intel. AFAIK we don't have the equivalent on Linux. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
