1. There is only room for one hard drive in a laptop computer. So don't plan on being able to just "add" a second hard drive somewhere inside. An external USB one yes, but not an internal one,
2. About upgrading to a 7200 RPM hard drive, consider this. My notebook came with a 4200 RPM hard drive, When I saw that specification, I thought, "Wow, a 4200 RPM hard drive is ridiculously slow, that's the first thing I'm gonna upgrade." So I bought an 80gb 7200 RPM Hitachi Travelstar with 8 mb cache for around $130 and installed it.
Once the drive was up and running I did some benchmarks by timing how long the laptop took to boot to the desktop, and the new drive was only 5 seconds faster! So $130 spent just so the computer would boot up 5 seconds faster. A very poor investment, IMHO.
I did some research that confirmed my findings. An 80gb 2.5" 4200 RPM Hitachi Travelstar (my old hard drive) has a transfer rate of 18 mb per second. An 80 gb 2.5" 7200 RPM Hitachi Travelstar (the new one) has a data transfer rate of 19 mb per second. Not too impressive, to me at least, when I consider the money spent.
So bottom line, don't expect much improvement going to a 7200 RPM drive. I caught a lot of crap on the NewEgg product review site by pointing this out, but it's true, and I have the stats and firsthand experience to back it up.
1. While that is true of your laptop, it is certainly not true for all laptops. There are many machines caple of , and designed for 2 hard drives.
2. Depending on usage, a 7200RPM drive can make a HUGE difference. My old 4200RPM drive was ~22-25mbps. My 7k60 is ~30-33mbps. Where you got 19mbps from, I don't know, but it is DEAD wrong.
You are correct tha tit doesn't make a huge difference on just booting windows. It would be silly to purchase a faster HDD just ot get Windows to boot faster. There are many other reasons for utilizing a faster HDD though. Windows makes heavy use of the page file, even if you have sufficient RAM. For a gamer, especially when loading complex, large textures, a faster HDD makes a VERY noticable improvement during times of loading textures and loading levels. If you do a lot of DV work, you will slice the machine time greatly. TIme taken to let my machine encode DV work was almost caught in half (as it should have been) by upgrading to a 7200RPM drive.
Here is just one test done on the early 7k60 drives: http://www.xlr8yourmac.com/IDE/hitac...B_7200rpm.html
Take note of the file sizes and imagine working with 20-30+GB files. The difference in time is enormous for the small investment.
All that considered, the new 7k100 Hitachi drives (the one you bought) are even faster than the 7k60 drives (partly from faster, lighter arms, etc and partly for the increased aerial density). A 7k100 would provide an even bigger boost. If you caught a lot of flack on the eggs review boards for posting similar disinformation, it was most certainly deserved.
Real bottom line: You won't be blown away by boot time increases or application load times. If you are doing any kind of work that involves HDD thrashing, the increase from 4200 to 7200 is tremendous. In many cases (mine usage included), a considerably faster HDD will provide much more of a performance increase than increased RAM.
That entire post was a waste of bandwidth. An opinion is one thing, but flat out misinformation should probably be delivered a little more humbly.
