[quotemsg=10974014,0,1288539]So expensive, yet how about its durability. With all that data you can put in an SSD, that will shorten its life still.[/quotemsg]
SSDs in general have about the same or better use life compared to HDDs. This can be shown in raw specs and doing the read/write math, or by reading some of the reports that Google has published over the last few years showing that the failure rate is roughly the same.
If you go out and buy the cheapest SSD on the market, then yes, be concerned, but it is because of the cheap controllers used, or failure of something on the PCB that is going to cause it to die, not read/write durability. That just never happens. High end SSDs like Intel's use good controllers and good boards, so this is really a non-issue.
SSDs use less power, allow more users per GB or more users per drive, put out less noise, require less cooling, and often times offer higher data density in your server. They are not cheap enough to really justify in a small business yet, but for anyone in a mid to large size business it is time to at least start to look at upgrading. They provide the ability to have less hardware to support for the same workload on the administrator's end, and they make network resources fly on the user experience end. The payoff for medium sized businesses is there if you look for it, but it may be a while before it is really worth it for small businesses.
