The comment regarding SSD 'reducing the volume' [acoustic noise of rotating media] is an excellent point also!
So that's advances in :
- massive speed, some reduction in power consumed, decent reduction in heat, silent and compatibility [sata3]
....
The 'sweet spot' of cost as far as I'm concerned, in the lastest 'fast SSD' is for the 500GB type .... I think it won't be long before that migrates to the 1TB storage capacity.
The cost of the latest SSD 500GB [in my local] is somewhere between the cost of a 2TB .. 4TB current fast conventional hard drive.
...
I get something like 384MB/s reads 'avaerage' in my 'HD Tach' measurements for the Seagate fast ssd. [mix of block sizes in test]
For the big stuff, the current crop of 2TB .. 4TB conventional hard disks are crazy [low] prices ..... and the performance is also pretty exceptional ... I'm just starting to migrate to 4TB hard disks for the 'large end'.
Of course, with so many options on the 'storage pyramid'
it really is important to have efficient 'archiving' tools.
GoodSync is the finest I have used and makes light work of even the heaviest 'network archiving / synchronisation' type jobs. It blitzes thru it's tasks with great levels of reporting and 'accountability'
