I've set up some blazingly fast SSD based servers, the first one in 2007, using 16GB MTron SSDs. SSDs are a game changer for databases.

I totally agree. Moore's Law is completely inapplicable when it comes to disk performance.
Which is a strawman of your own invention that you are being an arse about, kbob didn't mention SSD performance .
kbob was replying to a post about a "performance boost" and then claimed without qualification that HDs were "on the Moore's Law trajectory"... I didn't invent anything here.

Me either. This is the single best improvement I've made in the last 4 to 5 years. My MBP is awesome with this X25-M. I have adapted myself to use this little 160gb space very confortably using some external storage at home. This is great! I sure do recommend this to anyone!
I have an 80 gb intel x-25m in my 13 inch MBP but I also took out the superdrive and installed a 500gb live in an enclosure in the optical bay.
How does that affect heat and battery life? Does the second disk switch off when not in use?

Yep, it is off when it isn't and use. It does affect battery a little bit but I have found it be negligible.

#126I would like to make the switch but am currently broke. I can get 2x2TB for the price of a 128GB SSD and RAID them. The price still doesn't justify the "snappiness" in my opinion since RAID'd drives provide a pretty good performance increase as well as a size benefit. Keep in mind that size is important to me right now as I use my PC as a media server to my house and also a development machine.
I did this, and boy do I wish I would have added a second raid, or even single drive, for my OS. My computer becomes unusable when I thrash on the drives by unraring a large archive or something. I am going to toss in a mid-level SSD for the OS so I can avoid this hit.
Yeah I actually have 3x750gb right now for media storage and a 500gb drive for OS. I get a performance boost from the RAID, and don't have it impact my OS. Ideally I would toss in another 500gb and RAID for performance on my main drive, but I haven't gotten around to it yet. SSD would be nice, but 500gb HD for $60 is hard to beat.

#127We are using MLC SSD's in production for our Cassandra clusters. It is very important to consider your workload when implementing SSD's in a production application. There are MLC SSD's and SLC SSD's. The former being reasonably priced (think MLC SSD's have a fixed write lifetime and will die or degrade after a certain number of writes. SLC SSD's have no such limits. Cassandra for example has a very predictable write…

#128What I'm interested in is the effect of SSDs on compile time, which is the biggest bottleneck to my productivity. In my case, the build time for Java projects in Eclipse. I've read conflicting stories of how SSD affects this. Over here: http://stackoverflow.com/questions/499889/ssd-and-programmin... its mentioned that CPU is by and large the bottleneck but over here: http://javamoods.blogspot.com/2010/04/hdd-ssd-batt…
We halved build times going from velociraptors to x25-e for a fairly big flash build. Made more of a difference than core2duo to i7 extreme

#129We are using 4x 512GB SSDs (boy, these were expensive!) in a 16-core i7 computer, running in production using PostgreSQL 9.0.0, Glassfish 3.1 and ActiveMQ. Works great, and we do heavy queries at lightning speed. We currently run Ubuntu Linux on it but would switch to FreeBSD 8.x if the Java support was better.
are they raided?
Yes, RAID-1 on each pair.

Which brand and model were the ones you put in the postgres server?
MMDOE56G, that's a Samsung 256GB SSD. [Sorry, I know I wrote 512GB and honestly I don't know why I didn't catch it before now.]
