 as long its SATA, 9.5 mm thickness and 2.5 inch factor, then it is okay, you can choose any maker... but people usually buy Seagate, Hitachi and WD.

thank you.

couple more questions, what are the benefits for a 7200 rpm vs 5400 rpm? and cache, what is the difference b/w 8 and 16?

The 7200 rpm is faster in seek and transfer speed for obvious reasons, but it also consumes more battery power as you maybe aware, in addition it generates slightly more heat. So you got to weight up which one is more important.

 

The cache size will decrease harddrive spin time slightly by prefetching certain data, but nowadays in laptop it is more important in shock proofing feature (do you know how G-shock in Sony CD walkman functions?), as when the laptop detects unbalancing motion, it will quickly park its head to prevent physical damage (usually the whole process completes within a few millisecs). If you have a large cache, the hdd would transfer the likely needed data from the platter to the cache, so you wouldn't experience the sudden stop start process, obviously how well this cache works, would depend on the amount of data you use within that milliseconds and how long the shock lasts for. 

 

If you do lot of video editting, then this cache would be inadequate, but if you are listening to MP3, then it work quite well.

All good info here, but there is a negligible power/heat difference between 7200 and 5400 rpm drives. If you can afford it, go for 7200rpm by far.

Agreed. I upgraded from 80GB/5,400 to 320GB/7,200 and see no difference in heat. Performance has improved significantly.

 

The sweet spot these days in notebook HD pricing is 320GB. You can get a Hitachi 7K320 320GB 7,200rpm drive on sale for around $60 at places like newegg and zipzoomfly, etc.

Btw stay with the SATA 1.5Gb/s -- T61 doesn't support SATA 3.0 Gb/s, see this thread.

 

Edit: 3.0Gb/s hard disks will work in a T61, they just won't be any faster than a 1.5Gb/s drive would.

Re: So i have to replace my hard drive...how to choose?

Really? Tha kinda sucks as it takes out the option of a 500 GB hdd, and limits me to only these two options for 320 gb ( If I order from newegg, work pays for it.)

edit: are you sure the sata 3.0 isnt supported? I did a google, and it seems as though it is supported. threads like this seem quite prevelant. http://forum.notebookreview.com/showthread.php?t=242110

Did you look at Lenovo's official answer in the thread I referenced?

I did and it seems it will run the 3.0s just fine, it just won't run at 3.0. so i would be fine getting a 3.0 knowing it will run at 1.5I
