Questions that have probably been asked before

Yes.

And why no bothering?

 

Hard drives when powered off can withstand up to 320G's of acceleration before being damaged. You could probably drop a hard drive from 10 feet high, and if it wasn't for the denting of the casing and possibly the circuit board on it breaking, the hard drive itself would still work perfectly. Now since your hard drive is cushioned inside an aluminum casing, it's a moot point. You'll be quite fine lugging it around as much as you like.

 

An SSD will probably give you better performance than a 3.06GHz CPU. The CPU makes almost no difference for powering up or running programs, but a SSD will.

 

The SSD will give you better and faster performance, its dead quiet and you can't damage it via sharp movements. I'm going to get the 128GB on my next 15" MBP, and it would be a bonus if you were traveling with the machine on.

*It also increases the battery life a bit

 

Non-SSD drives park their heads when they're powered down. All Mac notebooks have the Sudden Motion Sensor, so even if they're not powered down, if there's a sudden motion (i.e. you drop your laptop while it's still turned on), the drive is supposed to have enough time to park the heads before it crashes to the floor.

There are a gazllion people that have been lugging non-SSD equipped notebooks around. For years. If you plan on having it off, or in sleep, while you're walking around, I think you have very little to worry about (when it comes to non-SSD hard drive damage). If you're ultra-worried about this, though, consider the SSD. Law of attraction being what it is and all...

 

Even if your hard drive fails. It's your hard drive... You replace it and life goes on (Assuming you have backed it up).

 

I had a hard drive fail the day before a presentation to a potential client... I stayed up all night restoring, testing, etc.

I use SSDs now in my laptops.

 

SSDs are nice, but expensive.

Even if you have an SSD, you should back up. So incorporate the cost of backing up in to your computer budget. What if your computer is stolen, or if your computer meets with a warm cup of coffee?
• totally automatic Backblaze online backup: $5/month.
• external hard drive, you have to remember to plug it in: $100-150
• totally automatic Time Capsule local backup: $299

Either the HDD or the SSD will be very nice in your MacBook Pro.

 

I hope you are backing up your SSD's. I am not saying that it's not a superior, more promising technology, but HDD's have been with us quite a long time. Long enough to know that anything that isn't saved in 2+ locations is prone to go extinct...

 

Since you won't bother to search first, I will ignore your question.
