Good to know. cfdisk was my favorite, too. You can still use it, you just have to specify the start sector yourself and don't accept the default. :) 4MB is almost always a safe starting point to use for SSD or other flash-based storage. (Most fdisk tools default now to 1MB which should be safe for all HDDs but not necessarily the best choice for flash storage because of erase blocks etc.) Unfortunately the exact perfect alignment depends on the specific device you're using so there is no catch-all solution. There are tools like flashbench will will try to reveal the optimal settings via destructive tests.

Thank you, Cheers My intuition said that separating a hard disk into several partitions should result in a slightly faster system, because writes to different partitions will not cause metadata contention (e.g., journal, volume bitmap, etc.) But that's just my intuition; I'd be very interested in a definitive answer from anyone well-versed in filesystems.

My nearly decade-old laptop, with a crappy Chinese brand of PATA SSD blows away my i7 desktop which has a fast HDD and 12GB of RAM when it comes to emerge --sync and portage searches. Not to mention the laptop boots to graphical login prompt in less than 5 seconds after I choose Linux in the GRUB menu. Less heat and power usage, too. So I think any modern computer with modern SSD should really fly. :)
