I'm needing to replace the HD of an early MacBook Pro, early 2011 unibody. The standard drives are up to 750GB but this one has 1TB.

What's a good tool to see all details of a drive? ..including RPM speed..

PS - and recommendations on the replacement as well? (I was supposing Newegg.com or iFixit.com to check on things.)

thanks

System Profiler (Serial-ATA) will give you the drive model number. From that you can Google all the specs for that drive.

The drive is empty and defective, but can mount alright.

..as you can see, I can't tell the RPM. I just don't want to buy a 5400RPM if this drive is 7200RPM - it needs to be a comparable swap.

There's more to the picture than rotation speed. Drive density also plays a role. In other words, some 5400 rpm drives are faster than some 7200 rpm drives, if they are of higher density. If you really want performance, go with a SSD. They're significantly faster than any 7200 rpm drive.

I hear ya.

I'm trying to swap for the same drive.

It's odd, I can't find a simple tool to tell me what the specs are of this drive. I found Blackmagic's speed tool, Disk Utility doesn't show it, TechTools Pro and Diskwarrior don't show it either.

I'll keep digging, and hope for someone to notice this thread that knows of a "go to" app for this.

thanks

There are no 7200RPM 1TB drives that will fit into a MacBook Pro, yet. It has to be 5400RPM.

You could also boot from your restore partition or from a USB restore drive and use Disk Utility to get the actual model number. Right now the model information you're seeing is from the laptop you booted into target disk mode. It's being reported as a firewire enclosure made by Apple.

*edit* But that is all kind of a PITA compared to taking the bottom case off and just inspecting the drive.

I decided to boot the MBP with an external drive to check Sys Prof, in that way it was from the S-ATA and I saw the specs. It's a Samsung HN-M101MBB, which is a 5400rpm.

thanks

PS - I'd still love a recommendation for the BEST drive tool! =)

I have yet to see one that isn't too tall. Here is the only one 7200RPM 1TB 2.5" drive I can find on Newegg(it's 15mm tall, I'm pretty sure 12.5mm is the max a unibody MBP can accept):
I stand corrected. I was looking at the 2.5" and not the 15mm.
