What SSD is suitable for my MacBook Pro?

I would like to replace the HDD with SSD for my Mid 2009 13” MacBook Pro 2.53 GHz Core 2 Duo with 4 GB RAM & 500 GB HDD

I don’t know what model to look for, what configuration, what SATA , memory type, etc.

Are there any troubles I could get into when doing this change.

Thanks anyone for suggestions.

Hi George,

I have a preference for Crucial and here is one of the recommended SSD drives for your system Crucial MX500 500GB SATA 2.5" 7mm (with 9.5mm adapter) Internal SSD or if your want to go larger capacity Crucial MX500 2TB SATA 2.5" 7mm (with 9.5mm adapter) Internal SSD.

Hope that this helps.

Hello Jim,

I was just checking up your recommendations.They have SATA 3 ,is the same with what I have in my laptop ,or itdoesn't matter , I don't know much about it.

Thank you.


Crucial has SATA 3, it matters as far as access times go but I believe a older SATA will work, at least I have done it before with no ill effects. here is the link to the drives you need


Thank you Jim.


One more thing, after I replace the HDD with SSD is it possible to install OSx from the original dvd that came with my mac, which is Leopard or from a dvd where I have Snow Leopard or I can go straight with El Capitan which I think it's maximum my system accepts, via internet install?


@george72 - Your system does not offer internet recovery so that won't work. Before you take your HD out setup a USB thumb drive as a bootable OS installer. Here's how How to make a bootable OS X 10.11 El Capitan installer drive Or, get a SATA to USB adapter like this one StarTech 2.5" SATA to USB adapter or get a external case to hold your drive like this one OWC Mercury On-The-Go HD case

@jwmurphyjr & @wonderman & @george72 - SATA specs do matter! Yes, it can be confusing!

George your system is only SATA II (3.0 Gb/s). The SATA spec is written to allow older drives to work in newer systems. Back then drives where fixed speed or had a jumper to set the I/O speed.

So to clarify a Fixed SATA III (6.0 gb/s) speed drive won't work properly in a SATA II (3.0 Gb/s) or SATA I (1.5 Gb/s) system. But! A Fixed SATA I or SATA II drive will work in a SATA III system.

The drive makers realized this was not what people where doing! Instead of re-using their older drives many people where upgrading their drives to larger units. Lets just say a lot of people where having issues back then.

To make things easier the drive makers stole auto sense technology from the Ethernet networking world. This tech allowed the drive to sense the I/O of the system and then dialing in on what it sensed! These newer Auto sense drives became the go to drives as they do in fact work in any system

So an Auto sense SATA III drive will dial back to SATA II to matching your SATA II system! All was well! And for many a year the issues with fitting drives into older systems,s was not an issue!

Now we do have a new problem as over the last few years to be price competitive many drive makers are dropping this auto sense circuitry! Don't forget olderSATA I and SATA II systems are mostly no longer being upgraded or even used! So the need for the Auto sense logic is just not needed as much.

Once again we need to be careful on what drive you use! Some drives are still auto sense and you do need to make sure you use one in your system or a fixed SATA II drive!

You need to review the spec sheets to figure out what the drive offers. Here's the two drives:

Crucial MX500

Samsung 860 EVO

You want to check the interface line looking in the spec sheet, to see if your systems SATA I/O speed is listed Auto Sense. If its not the drive most likely won't work reliably Fixed Speed. If it's not written I wound't trust what people tell you.
