SSD The Hype Continues
How fast is fast enough??
How power friendly?
What does good enough look like??
Latency times soooooo low.....
These and other statements are things we are use to seeing from the varios makers of these sooper dooper array makers and i get the claims - i really do...
But honestly - what is actually good enough
I get that SSD as a technology is cool, I also get that it can provide a whole bunch of enabling functions as a result of its low-latency characteristics, I get that it has an interesting power profile (sometimes)...
But (and when is there not a but) - Price is still an interesting discussion... There has to be an inflection point of the cost of drives to make this worth considering, OR - array makers, please stop selling at such a big cost point - so that we can marry up value / reward discussions
ok.. and here it comes - the whinge.. Please dont tell me its a lifestyle statement (i am not even sure what this means - but apparently it is!!) and please please please dont tell me that it will make ALL of my infrastructure and applications run far faster - the last time i looked, we hadnt broken the speed of light - so replication for write intensive applications still remains a problem - but NNNOOO apparently not... (Please install wormhole between point a and point b would be in the instruction manual i believe ;-)
So what points am i making....
- Yes i get that SSD tech is good and its here and its gonna rule the world
- There are stll some parts of the tech puzzle for SSD arrays that need to be solved
- Price / Performance / Capability needs to get to a point where it is acceptable in equal measures
- in a lot of cases - the array tech you have on the floor today is good enough - its maybe just a little bulky
- We are probably getting to the last generation or two of spinning disk arrays - but they sure as hell arent dissapearing overnight
- NO ITS NOT A LIFESYTLE STATEMENT!!!
does this feel like the "no more tapes" conversation, or maybe "end of mainframe"?
