laptop hdd in desktop? - Page 2

Primu$: Don't forget you have to initialize the drive with windows before you can format and partition it, it should be an option in the right click menu....it's been a while since I've had a new HDD to add into a system so forgive me if I Can't remember exactly where that is.


You're wrong again, SATA 2 drives are spec'd to work backwards with SATA 1 controllers. Some controllers require a jumper on the drive to force SATA 1 and some older controllers from Via and SiS (like you'd ever buy a system with their chipsets anyway) won't take SATA 2 drives regardless. That being said GENERALLY SATA 2 drives will work in a SATA 1 controller. Also, Laptop SATA Drives adhere to the SATA spec just like desktop drives. In my 10 minutes of searching google and Wikipedia I couldn't find anything like you're suggesting with swapped pins and such.

Don't understand why you would want one considering they run slower, and have smaller storage

They don't run more slowly.....

less heat and less noise and lower power requirements... those might be a few reasons.

7,200 isn't completly standard for notebooks ALOT still use 5,400 even mine I just bought does. and they run in ATA 1.5 transfer while most now are SATA 3.0 GB


Less heat-all about fan placement tbh, and why would heat be an issue?
Less noise- they hardly even make noise, and if your that much of a noise whore get a P180, or something with a tight cage to keep them from vibrating.
Lower Power-wtf 1 normal 7,200 hardrive takes up like 20 watts..

Well, heat is an issue. fan placement will indeed help cooling, but it still does not deal with the fact that a 2.5" notebook drive is something like 1/6th the volume of the 3.5" desktop drives, and let's just say that they are running at the same temperature inside the case. the 2.5" drive has physically less volume, mass, surface area, etc, which will all affect the heat dissapation and also, just the total amount of heat it gives off.

the noise factor, i agree, isn't all that much different, but when you add those fans into the equation, sure you could have 1 or 2 fans blowing on an array of 3.5" drives, but that will make more noise. a lot of 2.5" drives don't really need to be actively cooled unless there are a good amount of them, and even then, you probably need fewer fans per amount of drives.

finally, for power consumption, just based on 2 somewhat random sources (i went to thg since i knew it would be there, and the other just came up on google), notebook drives use significantly less power, most likely because they are just physically smaller.

on thg, you find the max power consumption is in the range of about 4W. on that other site, going about 3/4 down the page (since most people, i think, use both the 12V and 5V), you find that the idle power consumption of desktop drives is in the 6W range.

Touch'e

But Simply becasue of size (GB wise) I would go with a 3.5, and after taking 3 hours to wire my P180 (P182 soon!!!) I really wouldn't want to modify my rack into a 2.5

2.5" Hard Drives have areal density many times greater than that of Desktop drives with similar capacity. This keeps their performance inline with a desktop drive, even with slower spindle speeds. In some applications (Small Form Factor) it is more advantageous to use a 2.5" hard drive.
