[QUOTE="mm1352000, post: 1043016, member: 82144"] I suppose you could get away with using an SSD. It just depends how long you want it to last. The sorts of number that Anandtech throws around in some of its reviews suggest drives should go the distance even if you're writing an extraordinary amount of data. Take the latest Intel SSD review: [url]http://www.anandtech.com/show/7438/intel-ssd-530-240gb-review[/url] They say the drive is rated for 20 GB/day for 5 years => ~36500 GB lifetime writes. Of course that number varies from drive to drive based on the amount of spare area, the wear levelling algorithm, the write magnification, how compressible the data is, and the type of NAND... but if you take it as a rough estimate, and combine it with a channel bitrate estimate (assumption: video and audio is incompressible) - lets say an HD channel at 10 Mb/s => 1.25 MB/s => ~4.5 GB/hour => ~105 GB/24 hours... Basically, if one MP client timeshifts all day and all night everyday, they'd do roughly 5 times the number of rated writes and you could expect the drive to last about 1 year. The lifetime halves if two MP clients timeshift all day and all night; the lifetime doubles if the one person only watches for 12 hours a day etc. etc. etc. Another way of looking at it: to stay within the rating, clients could watch TV for a total of 5 hours per day (and the drive should last for 5 years). YMMV 4 GB is on the small side for a RAM disk because you need to leave some RAM for the operating system. However, you don't have to worry so much about lifetime. Your choice. :) [/QUOTE]
