And finally -- the price isn't even that good! Why pay $140 for an unproven Kogan drive, when you can get a *proven* decent drive like the Crucial MX100 256GB for $110? http://www.amazon.com/Crucial-MX100-adapter-Internal-CT256MX100SSD1/dp/B00 KFAGCWK That's an excellent price for a 256GB SSD. We can expect prices and capacity to improve further in coming years.
Does Linux still require edits to /etc/fstab to support Trim and other SSD optimizations, or is it all done by default now?
Yes, but trim is often undesirable. When I had it enabled with BTRFS performance suffered significantly. It will be a long time before that's a feature that can be enabled by default.
A further development of note is the move to SSDs attached directly to the PCI-Express bus, with no drive controller required. Example: http://www.ramcity.com.au/blog/all-about-pcie-ssds-part-1-windows-linux/1313 71 (still expensive, but this should change.)
The Intel SSDs I have can't sustain 300MB/s and when under significant load (EG swapping) they give even less performance. A SSD that could sustain 300MB/s under all conditions would be a significant improvement over all storage I've used. On Wed, 23 Jul 2014 13:13:57 Andrew Spiers wrote:
I read somewhere recently (sorry I forget where) that price parity with rotating disks could come in around 5-10 years.
They already have for storage capacities of 60G or less. If you want a workstation for typical business use (IE email, wordprocessing, etc) then 60G should be adequate storage. Even for 120G of storage the cost of SSD isn't much greater than that of hard drives (~$75 vs ~$55). But for most people the price difference isn't the difference in replacement cost but the fact that hard drives ship with most machines, so the price difference is $0 vs $55. For most people on this list when adding an extra storage device to a machine it's a matter of using one of the spare disks that we have on the shelf vs buying a SSD. Effective price parity will happen when more systems ship with SSD by default. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
