one disadvantage to a solid state type drive, is that if the drive is not powered up for long periods the data can be at risk. How much of a risk this is varies depending on the type of flash chips used. This is not true for a spindle type drive unless it sits for years and years. You would have to be pretty rich to buy a few solid state drives and not even bother to plug them in for a year...but still just thought I'd throw it out there.
Another disadvantage I can think of is that solid state drives in general are not as tolerant to sudden loss of system power, crashes or maybe even just certain power supplies etc. I think all the ssd makers should put capacitors on the drives such as the crucial m500's have really. Hopefully with ocz going the way of the buffalo and more time for controller revisions etc reliability with the ssd will improve somewhat.

It's an unfortunate reality that 1's hold a charge in the cell over a certain threshold that can fall naturally over time but there is no exact timeframe for when it occurs and it happens to different cells at different rates, no two SSD's are the same... the standard rule of thumb of backing up applies more than ever these days. At least it's extremely easy with massive HDD's being so inexpensive and NAS easily being in the hands of consumers as well as software so easy to set up a blind chimp could by accidentally dropping a banana peel on a keyboard.Uh oh. I never heard that one and I've got a ssd backup thrown in a drawer......
Well, don't worry. Consumer flash is rated to retain data at around room temp for 1 year at its rated p/e cycles.Uh oh. I never heard that one and I've got a ssd backup thrown in a drawer......
Yes. They only yodeled it from every mountaintop when they came out...Not to derail, but the Crucial M500's have caps?
I can't really think of any other than cost.
I think one of the main initial disadvantages was that the SSD performance degrades over time. The more you use it, the quicker it degrades, but that doesn't seem to be a hot topic for discussion nowadays which makes me think that probably got that settled or at least minimized the impact of it.
True. However, reliability testing of SSDs exposed to power outages, showed that having capacitor backup means nothing - capacitor equipped suffered from the same data corrupting power-loss firmware bugs as non-capacitor drives.Yes. They only yodeled it from every mountaintop when they came out...

Are there ANY disadvantages to SSDs versus the traditional Hard Drives besides cost?
(why were Vertexes and Vectors dying so much more than 520s, 300s, M4s, M5Ss, 830s, 840s, and so on, FI?), and deceiving even their own shareholders at times.
OCZ was very depend on SandForce Firmware.
CRC correction for old Vertex, Agility, Vectors was realy poor (ReedSolom) , and couldn't cover all the errors during reading nands. For the rest drives you mentioned, CRC correction BCH, which much more powerfull .
And even this doesn't help much , Samsung 830 Pro, Micron c400 (Van-Gogh), Intel 320 (Postville ) all of them can die on FW level , when CRC mechanism can't correct mistakes.
Sandforce has nothing to do with it. Intel uses Sandforece. I have two SSDs that are Sandforce; a G.Skill Sniper with a tera byte of data written to it and an Adata. So far they have been going strong.
but by hyping too much, making sure first-time customers would not become repeat customers
