Based on the newest rumor of the new MBA containing SSD capable of outputting 400MBps:

https://www.macrumors.com/2011/07/04/next-macbook-air-to-adopt-faster-more-power-efficient-ssd/

Got me to thinking, would the everyday user even see the difference in speed? And if any difference is perceived then is it more based on the newer chipset than the SSD?

Or was this purely implemented to eliminate the slowdown caused by Lion's encryption function?

Also, somewhat off topic question, as SSD approach RAM speeds could we see the elimination of RAM all together?

Faster speeds allow good code writers to be spectaular, and sloppy ones to get away with murder....just ask microsoft about the latter....lol

I would say no on the combining RAM.

RAM is volatile meaning that when the power is cut (turning off the computer) the memory is cleared.

The flash used in SSDs is non volatile meaning that it can retain its data with no power.

Haha. Wait were you being funny?

I mean as in, why can't RAM be like an SSD, if this were the case? A few posts up someone asked about RAM being used with flash but that wouldn't work. What I'm wondering is why can't RAM be like flash memory?

Unless it's just... not made to be that. As in, it isn't in the code itself for RAM and the entire machine as a whole to work in the way that I'm suggesting. Doesn't really matter to me though as I never need more than 4 gigs. Just some food for thought :)

The article claimed that it would output 400Mbs, not 400MBs. 400 megabits per second. Also SSDs and RAM do different tasks.

SSD are not approaching RAM speeds, RAM is getting further away from SSDs.

Technically one means 400 megabits per second, the other means 400 megs... total. Which is technically wrong. Of course i don't really care; as you stated it is a capital letter, however it kind of changes the meaning.

Actually, the article did mention 400Mb/s, as someone stated above me, wich is not impressive at all (50MB/s), but some others articles mentioned 400MB/s... By the way, still with 400MB/s, it would be painfully slow to use it as RAM, simce RAM has speed of x(x)GB/s... Not to mention SSD isn't suitable for similar usage since it still has wear level.

Combined with faster processors - this could mean serious competition for the 13" MBP (but nobody will know until it's out. Rumors are the consolation price for a lack of information).

Megabits and megabytes are not the same thing.

The MBP still uses full voltage chips. They will probably still out perform the LV and ULV versions of the same chip despite of the SSD.

Personally I would rather keep memory separate from disk. Something about reserving portions of disk as memory just seems wasteful. And limits expansion.

400 MB/s is on par with some of the new SATA III drives out there like the Crucial m4 and Vertex 3's. It's definitely nice but not Earth shattering exciting.
