We use them in a healthcare environment for our production system and some database systems. The nightly processing for data extraction and reports showed significant improvement. Things that used to take over 10 hours are down to about 45 minutes. I don't know what the old drive speeds were for comparison, but they weren't more than a year or two old.

Our Server team is selective with the drives due to cost and making sure the problem area would really benefit from that type of drive.

I've bought a Crucial RealSSD C300 256GB for my new 15" MBP i7 (2010). It worked fine but broke after I've bought another one until my dealer does RMA in the hope that it's not a "generic" problem. TL;DR SSD break out of the sudden and usually everything is lost. Don't use a SSD without having backups on a daily basis!

15 years of my IT career I've never lost any hard disc out of the sudden (~100). A HDD usually does make sounds, throws smart errors or shows signs (starting file system corruption).

SSD die just out of the sudden without any warning.

I'm not using one in a production web environment, but my Macbook Pro has one in it now and it's phenomenal. Photoshop boots up in quite literally 3 seconds or less (cold startup) and every other action imaginable is noticeably quicker. I used to feel like browsing files in the Finder was slower than it was for me on my old Windows XP machines but eventually I got used to it. I use keyboard navigation as well, so it…

I got one when I bought my new laptop, and between SSDs and Windows Seven it has been the greatest productivity boost I've ever gotten out of a hardware upgrade in literally a decade. My machine now screams -- going from a cold boot I can get Chrome open before wireless handshakes are complete.

Very interesting. Do you notice any slow down over time? I think I'm right in saying that OSX doesn't implement the trim command or something like that?

This is correct (no support for TRIM), but the performance degradation is not very significant. I'm certain I've used all blocks on my SSD and it's still way faster than HD for random access. Sequential write is noticably slower, but that doesn't happen often -- copying a large backup, etc, but then I can do something else or get a drink while waiting. Random = interactive = fast.

15 years of my IT career I've never lost any hard disc out of the sudden (~100). A HDD usually does make sounds, throws smart errors or shows signs (starting file system corruption). SSD die just out of the sudden without any warning.

I've had it happen twice, once in a laptop (the famous click-of-death, just like that, no warning at all), the other time in a server that was in a rack where the audible beep from the raid array wasn't heard and the monitoring utility was mis-configured so it was sending out its warnings to nobody at all.

The second one was pretty nasty because of course we only found out about that one when enough drives had failed that we couldn't recover any more, and as long as it worked it seemed to work perfect.

Of course there is no way to know how long that second one had been giving off warning signs, by the simple fact that several drives had failed it must have been dead a long time before we found out about it.

Lesson learned: after configuring a raid system test if your 'drive dead' signal actually reaches an operator.

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.

Moore's law is about transistor counts, not speed, and is directly applicable to SSDs.

Intel's SSDs don't perform worse if you don't use TRIM. They pre-erase and move blocks of data around in background so that when you go to write there is always some space to do so.

The downside is that sequential writes are bandwidth-limited compared to other SSDs, but this doesn't matter in practice with small random writes completing very quickly.
