Which choice would be better ?

What is your other option? You could use an SSD for a cache drive so you don't have to manually move stuff over.

Well all the options are there, a ssd and a hard drive, only a hard drive, and which hard drive.

And sorry, but what is a cache drive ?:S

Also, I have an actual drive (500GB) which I would keep, for my backup. For the size, I only use 150GB for OS, Documents and Programs, so 600 would be too much.
Is SSD for boot is necessary ?
What does cache memory means on a hard drive ?
64MB ? 32 MB ?

I have a 600GB velociraptor in a Corsair 600t case and heat, noise or vibration have never been a problem. It boots the computer in about 45 secs and program load time are very good.

  Hi Leonard, You seemed knowledgeable so I hoped you might be able to answer a question. I'm also looking to upgrade hdd, but laptop. faster/more space. have samsung sf310, 13", 2.66-293gh.z, 4gb ram, 300gb hdd: 5400rpm(should be 3gb/s "transfer rate", 7mmH/9.5mmH (2.5")SATA HDD/SDD. shouldn't a compatable hdd/ssd, but with a higher transfer rate, ie 6gb/s still work, ie can't my laptop take advantage of this faster transfer rate? I was under the impression that my laptop would be fully compatable with a 6gb/s transfer hdd/ssd, like the (Seagate Momentus XT 750 GB 7200RPM SATA 6Gb/s 32 MB Cache 2.5 Inch Solid State Hybrid Drive ST750LX003.)

Hi  
Well first question, are you sure if you have a SATA revision 3.0 (Sata 6GB/s) inside of you laptop ? Not juste an eSATA port (External SATA) on the side of your laptop. Secondly, if not, it's maybe not really worth the price of a SATA3 Hdd but still, normally it has a smaller seek time, still better read/write speeds and more space(now the minimum space is bigger than before) And if you get a good drive, mabe you will be able to put it inside of an enclosure when you'll change for a laptop, (I suggest for all your old drives)

Since I'm not a professionnal, and I don't know what the heck is a Solid State ?HYBRID? Drive I don't think I'm the best choice for information :S

Sorry for my english, second language
