Compatibility with hard drive macbook 13"

Welcome to Apple Discussions!

I think any of those drives would work, but you probably would want to avoid buying one with a built in motion sensor, as it could conflict with Apple's built in Sudden Motion Sensor. With the WD Scorpio Black, It's called a "free fall sensor". With Seagate drives, it's called "G-Force Technology". Study the manufacturer's web site for more detailed specifications, and post back with model numbers once you have your choices narrowed down.

Good luck!

Between the two WD models WD5000BEKT is a definitive winner since it has 16mb cache vs 8 and 7200 rpm vs 5400 and amazingly 1.80 watts max power consumption vs 2.50 . So there is not even a second doubt between those two .and between WD5000BEKT and the seagate although they are almost identical by tech specs I would still go for the WD because segate's current is rated at 1A max and seagate at only 0.3A . Which means it does the same job using much less current therefore giving longer battery time for you and having less environmental impact .. So there is a clear winner for me and that is WD5000BEKT .. As for the issues with sudden motion sensor I wouldn't worry too much .. it's a feature to aid a hard disk with no suck sensor onboard in case of a sudden drop.If tho you buy a hard disk with one you can ( and should ) easily disable the apple sudden motion sensor and live a happy life with the on board sensor of the drive since it will definitely be faster to react then an external one and will be better suiting since it already came built in the drive.I don't think me posting how to would be appreciated on these forums but a simple google search on how to disable the sudden motion sensor will get you there in no time .

Funny I asked an almost identical question regarding the same drives earlier.

To me, the Momentus XT hybrid would be the clear winner performance wise (I did choose/order it in the end - I'll let you know the results if interested). It has 32mb cache instead of WD's 16mb max, in addition to 4gb of SSD memory, which would have endless application in terms of buffering/performance enhancements.

Anyways, my main concern with the drive was the power consumption (for any drive at that). Not so much in terms of battery life (I almost always have the laptop plugged in, power outlets are everywhere), but in terms of the capacity of the power supply in the laptop itself. I have yet to find out what type of power supply/capacity is in the laptop in terms of wattage. Can anyone direct me? In the end I took a leap of faith because other users have used this HDD with MBPs with no power problems... apparently.

My 2 cents...

I don't think any 2.5" drive that fits in your MBP can draw too much power.first off they all follow certain criteria when they are producing those units secondly the race is towards producing less power hungry equipment .I can say it will be no problem at all ..

If the XT was included in the previous post I would also definitely opt for that . With the ssd buffer story that drive is destined to be a monster ..nice buy . .

yes that one is a true hero .. incredible power consumption with solid performance .. should be perfect .

Seagate draws 3 times more power than the scorpio black and there are a few reports in the forums that indicate this might cause a problem ..Also by looking at their specs I doubt it has superior performance over the WD ..

here are both the specs :

the speed downgrade of the interface will not matter much because the drive is not fast enough to be limited by even the 1.5Gb/s so if that help compatibility then why not .the funnel I didn't exactly get

I 'm glad if this helped a bit .. take care

Interestingly enough my 2010 MBP 15" came from Apple with a Seagate drive with the built in motion sensor.

From the System Profiler...

+ST9500420ASG (500GB 7200 rpm)+

Having put Seagate and WD drives with the motion sensor into 4 different models of MBP can anyone comment on the specific nature of the conflict or what could result?
