Is it worth adding the 2nd hard drive in place of the optical drive?

I’ve got the 500gb ssd arrived and just waiting on the rest of the bits to arrive but I’m wondering whether it’s worth removing the optical drive and replacing with the original mechanical hard drive if I’m fitting the 500gb ssd where the original drive was located? Or is it worth doing the conversion and when I can adding the 2nd hard with another ssd?

First make sure the SSD you ordered will even work in your system before you open the package! Your system only offers SATA II (3.0 Gb/s) SATA ports!

Your systems specs: 15" MacBook Pro Core 2 Duo (Unibody)

Hi Dan I got it from iFixit in their upgrade system so if they've sent it to me then I hope it'll be fine otherwise it'll be going back. According to the samsung site you are correct it does run Sata 6 but is also compatible with Sata 1.5. This is all new to me so forgive me if some of it goes over my head as I would have thought that if I've given them the info why would they send out an incompatible drive to myself?

What made sense years ago, really doesn’t make sense today. I don’t recommend switching out the optical drive for a second drive. The first issue is the optical bay does not offer crash guard protection so placing a HDD into the optical bay puts the data on the HDD at risk. While one might think placing a SSD in the optical bay making it the boot drive, the systems firmware in this series expects an optical drive and shuts down the power so you can encounter corruption of the drive. So it’s best not doing it.

The last point is the cost of two 512 SSD’s is more than getting a single 1TB drive and to add to it the SATA ports are serially connected to the PCH logic so you don’t get the dual I/O some people wish for that used the full bandwidth of each connected drive.

For reference this is one of the few drives that offers support for the older SATA systems Samsung 860 EVO 2.5” SSD. Note the Interface line SATA 6 Gbps Interface, compatible with SATA 3 Gbps & 1.5 Gbps interfaces. Make sure your SSD spec sheet clearly states SATA II (3.0 Gb/s) support like Samsung does here.

Hi Dan

It'll be rather annoying if they have sent me the wrong drive seeing as I ordered it through iFixit and their upgrade pack for my MacBook pro. According to the samsung website this is what it says



SATA 6 Gb/s Interface, compatible with SATA 3 Gb/s & SATA 1.5 Gb/s interface

And if i'm reading that right not only did someone not notify me when my order wasn't able to be completed in full before sending it but they may have sent me the wrong drive as well. Does that look right to you as I won't be happy if that is the case.

@kain.harkins - I'm confused here, you ordered a Samsung SSD? If you did then you got the proper drive.

Let me try to explain...

Your old bike you had as a kid had a direct chain drive (Fixed) So other that your pedal power it could only go so fast. If you hit a steep hill you had the get off and walk up the hill.

Now In high school you got a 10 Speed! Now you could not only ride up the hill you could even push the bike to 34 MPH! On a flat road (Adjustable) Some newer bikes have variable drives (Auto) so you only needed to pedal the bike would pick the correct gearing.

Here with drives (HDD's & SSD's) we have Fix speed ones that only go one speed and we have others which used jumpers to set the speed (adjustable - old HDD's, no longer offered)

And in this case the Samsung SSD its Auto sense! So while the first noted speed is SATA III (6.0 Gb/s) it will automatically drop to SATA II (3.0 Gb/s) or even the slower SATA I (1.5 Gb/s).

So if iFixit sold you a Samsung SSD you're good!

Hi Dan sorry for the confusion. I’ll try to explain better than I did.

I ordered an upgrade kit for the late 2008 MacBook Pro from iFixit and a framework to replace the optical drive with either the new ssd or the mechanical drive which is already installed in the MacBook Pro (which according to the videos I’d seen was the way to go to help with cooling and also allowing for space for another drive to be installed)

The order when it arrived turned out only to be a part of the order because some of it was out of stock when I ordered it.

What I did receive was the hard drive frame to replace the optical drive with, 1 small Phillips head screwdriver with 2 tiny Phillips head screws and a Samsung evo 870 hard drive which confused me as when I placed the order the drive in the picture on the site showed the toolkit the caddy, a crucial ssd and that’s what I was expecting to receive, the spudger, screwdriver and various bits.

I know the 860 evo would work as I’ve seen it mentioned on a few different sites

I just didn’t know if the 870 would work with it not mentioning the SATA 2.0 on the Samsung site. Only the 3.0 and 1.5 if that makes sense now.

Originally I thought they sent it because they didn’t have any stock of the crucial or the 860 evos that I know work with my 15 inch late 2008 MacBook Pro.

Does that make more sense now?

Apparently the rest of the order will be with me sometime this week that was missing from the 1st package but I never chose the 870 that’s what was sent to me by iFixit so I don’t know if they’ve sent the wrong item or whether they have now. I know it’s not going to get the best out of the drive with the ssd being able to run at 6.0Gb/s compared to to what my system can run at which from what you’ve said is 3.0Gb/s. So I just wanted to make sure I could install it.

Again sorry for the confusion I’m new to all this and this I my first foray into MacBooks and upgrading them.

OK lets grab the Samsung 870 EVO SSD spec sheet As we can see the interface line is exactly the same as the 860 EVO SSD I had posted as an example.

Interface: SATA 6 Gb/s Interface, compatible with SATA 3 Gb/s & 1.5 interfaces

So let's de-confuse you! We know the numbers 1, 2, 3 and onward have a weight. So if I offered them in Roman I, II, III and on... We can see that have weight too!

So one of the problems the SATA standard hit was the Spec Number 3.0 is not the data rate! To simplify things most techs and many companies use the Roman numbers to call out the spec and use the Arabic numbers as the data rate as in 1.5 Gb/s, 3.0 Gb/s and 6.0 Gb/s So putting it all together we get SATA I (1.5 Gb/s), SATA II (3.0 Gb/s) and lastly, SATA III (6.0 Gb/s).

So now you have the tools to read things and understand what they mean.

So the Samsung 870 EVO is perfect for your system!

Now the bad news! I would just install the SSD replacing the HDD. All you'll encounter is issues using the optical drive carrier. A few years ago I maintained over 1,000 MacBook Pro's across three companies. I have a bald spot in my hair line from pulling it out trying to deal with the carriers. Sure! They will work for awhile then you'll find your data corrupted or the drive is fully gone! So unless you are very good in backing up your system, I think its a good game of Russian Roulette! Who will win you or the computer?
