Can I improve the load time of my 2nd internal hard drive?

I installed a SSHD (Hybrid drive) as a 2nd hard drive recently in my MacBook Pro, removing the optical drive.

I have noticed that it takes 30-45 seconds at times for the drive to be recognized by the OS for folders to appear and for me to get into the drive.

Is there a way to speed this up and have it respond faster?

Can you give us your last four digits of your serial number we can correctly identify your system, there are quite a few models of MacBook Pro's.

Dave I think you facing the optical drives SATA port issue many of the newer MacBook Pro's have.

Basically the Optical ports SATA port is not the same speed as the HD SATA port.

You'll need to get a fixed SATA speed drive SATA II (3.0 Gb/s) for use in the optical drive. Review this OWC note in red: OWC Data Doubler.

The Seagate SSHD drive won't work as the auto SATA speed sense circuit can't handle the odd SATA speed the optical drive SATA port in the system has.

I would recommend you move the Seagate SSHD drive over to the HD location and depending on what your HD is you might be able to move it over to the optical drives SATA port.

Just to be clear here, the issue is not the carrier its the Intel controller chip Apple used and the given CPU's speed (GHz). So no matter who's optical HD carrier you get they all have this problem.

I would also make sure your firmware is up to date. Review this Apple TN on how th check and update: EFI and SMC firmware updates for Intel-based Macs


One way to verify what you have is to see what the System Profile report tells you. To access it go to the Apple menu > About This Mac > More Info button > System Report button, then slide down to Storage. Then going to SATA/SATA Express will show you the different volumes. Take a snapshot of the two and post them here for us to see. If this is a WD Black² HD you should see two disks.

What happens when you use an external case or SATA to USB cable adapter to host the hard drive. Are things are faster?

Hi Dan. The serial number last four digits are: DV33

I also wanted to provide the link of what I did buy, from OWC actually - http://eshop.macsales.com/item/Other%20W...

Thanks so much for taking the time to help me out. I'm new to the site, so this is great. I will have to look around to see where I can help out other people.


Can you give us the model number of the drive its self.


Is this the drive you got? WD Black². Your link implies a Western Digital 1 TB SSHD. As far as I know WD never made a real SSHD only this dual drive. WD still doesn't support Mac's with their dual SSD/HD drive (Black² drive). HGST offers a real SSHD as an OEM product (its a subsidiary company of WD). As far as I know Seagate is the only maker of SSHD's that sells them as a user replaceable drive (Seagate Laptop SSDH).


It is not the WD Black drive you listed. I wonder if I should return it and then do a little more research on my drive options. It works most of the time but has trouble. I checked the firmware like you mentioned and I am uptodate. I have a 15" mbp mid-2012 model, non retina.


I take that back, this is the drive that I purchased, so I think you are correct. 1.0TB WD Scorpio Black 2.5 Hybrid HD/SSD
