SSD in optical frame from ifixit not working probably

Okay, so I have to change both the hard drive and the optical frame?

Could you possebly attach a link to that fram you recommend and maybe a new ssd drive if I had to change that too?

No, you missed it!

You don't need to replace your hard drive (HDD) you only need to replace the solid state drive (SSD) to one that is a fixed speed drive like the OWC - Mercury Electra series drives if you want to use a SSD in the optical drive carrier.

Frankly, I don't recommend using the optical drive carrier in this series because of this issue. I just tell people to use the HD bay drive only for their drive (either HDD or SSD) and call it a day.

Keep in mind a bigger SSD will offer more performance than two smaller ones you where planing on using here.

As an example my MacBook Pro has a 1 TB Samsung drive as it's only drive (HDD bay) and even though I don't use the optical drive that much its still present.

Thanks for answer Dan!

But I already have one ssd installed instead of the

Main hdd drive that came with the MacBook.

I have already switched out the Disk drive with the optical frame with one more ssd drive.

Do you understand what I’m trying to tell or am I doing a horrible job trying to explain my issue?

You are trying to setup a dual drive config using two SSD's, I get that. The issue is you have two different I/O ports here a SATA III (6.0 Gb/s) for the HD bay and a SATA II (3.0 Gb/s) for the optical bay.

I love Samsungs SSD's! They work almost everywhere but here!

The problem is like how an automatic transmission works Vs a stick shift within a car or truck. Sometimes an automatic is better (city driving) and a stick shift is better on distance driving over the highways and dirt roads in the back country. Here you can't use the automatic you need the stick as the optical bay is the back woods Vs the HD bay which is the city.

Does that help explain why you can't achieve what you want using a dual SSD setup with the Samsung SSD in the optical bay and why you need the OWC drive instead.

IF you where thinking RAID that won't really work either as the I/O speed needs to be the same which in this series it's not. If you had a MacBookPro7,1 then you could do a dual SSD setup running both ports at SATA III (6.0 Gb/s) and even setup a RAID drive! It's the only 13" Series that offers SATA III (6.0 Gb/s) in both ports. The other option is the 15" Series: MacBookPro9,1

The other direction which is the only way out here if you need the deeper storage is to just go back to the single drive config and use a bigger SSD. The bigger SSD will end up being faster as well as offer more storage if you really want SATA III performance.
