Replacing HD on two iMac 27" EMC 2639

Hi,

I was reading for the past few days on your website and as much as I read, I really get confused, I might being asking a repeated questions here but I thought it is better to put it all here and get myself on the right track before touching my two iMacs…

I have two iMac 27” EMCD 2639 with i7, one machine has only a 3TB HDD (no fusion drive) which is working fine (only it is now a bit slow at boot especially, this machine is in use for large video files and large VMware Fusion virtual machines, as I said it is slow at boot but after that it is fine…), the other machine has a fusion drive but the 3TB HDD is faulty and almost dead…

My plan was to upgrade the faulty drive on the 2nd machine with a SSD using one of your upgrade bundle and move the SSD blade to the 1st machine to be used as a fusion or dual hard disk, so:

Q1) is this going to work? I mean moving the SSD blade?

Q2) in your upgrade bundle there is no 2TB option although you are offering a 2TB SSD in the parts section, does that mean it is only limited to max. of 1TB?

Q3) If I just replace the faulty 3TB hard disk with another HDD (I have access to many), do I need the thermal sensor with the HDD, is there a way to tell if there is a thermal sensor in the HDD…

finally, I understood that upgrading to SSD is even better than having a fusion drive, which one should I choose, it is not about the cost at all, it is about the practical, safer and reliable way to go…

I will wait for your reply before doing any thing, sorry if it looks long or repeated and thank you…

1) You should be able to move the blade SSD, and it will appear as a second hard drive installed in the system. You will not be able to read any of the data on it though, and it will break your fusion setup, so make a backup before moving anything of course. You can technically make a fusion drive with them, but that will erase all data so again, make sure you have a backup. I probably wouldn’t do that though, what I’d do for your use-case is keep them separate, install macOS to the blade SSD and boot to that, and use the 3TB drive as a separate drive for storage for your documents and VM drives. Fusion drives don’t really provide much performance benefit over traditional hard drives.

2) If you’re referring to this bundle, 1TB is just the max iFixit will sell as a bundle, but a 2TB+ drive would be supported by your system. You would just need to buy the tools separately:

I would also highly recommend the Pro Tech Toolkit instead of the some of the stuff on this list if you plan on doing any more repairs than just this one in the future, since it comes with all kinds of handy tools.

Also, you can get much better high capacity drives than the ones iFixit sells for cheaper. Amazon has a Samsung 860 EVO in 2 and 4TB capacities for $298 (instead of $399) and $697 respectively.

3) Like I said you can buy the thermal sensor from OWC separately, but you can also use Macs Fan Control to link that fan to another nearby temperature sensor or just set a manual fan speed and it will work just as well without having to buy the extra hardware. The fans might spin up on boot but as soon as it boots and opens you can control them completely via software.

4) From a reliability and performance standpoint you should definitely go with an SSD. I almost never recommend hard drives until people start needing capacities >4TB or so because SSDs are so much better and cost effective. They typically last a lot longer than HDDs so no worries there. That being said, SSDs tend to fail hard when they fail, it’s much more difficult to recover data in most situations. But either way you go with, you should always have a backup solution, because all drives will fail. So it shouldn’t be a huge deciding factor.

Fusion drives are pretty worthless for most workloads, they aren’t going to bring the performance benefits you’re looking for unless you only deal with like a few applications or small documents which you clearly don’t. It’s basically a caching solution that is limited by the size of the SSD installed, which your video files and VMs are almost definitely larger than and therefore won’t benefit from it.

Hello,

thanks for the answers and the nicely packed information I got…

I took the first step and bought the pro tech toolkit and before deciding the final approach, I now got another iMac with fusion drive that has a 3TB second drive that is dead… so to make my decision I need to assure this: is it possible to remove the blade SSD and add a new SSD hard disk with the thermal sensor or it is possible to replace the dead hard disk with SSD one with thermal sensor and keep the blade SSD, from what I understand both options are correct or not ?

@atheerioy You can replace the dead 3TB drive with an SSD, and yes you'll want a thermal sensor, which you can either get in a kit or separately from somewhere like Amazon (https://www.amazon.com/OWC-Digital-Therm...).

You can keep the blade SSD if you want, but you should not make the two SSDs a fusion drive together. If you don't make them a fusion drive they will just appear as two different drives. If it's a 128GB blade, what I would do personally is install macOS and applications to that blade drive, and then keep files, etc on the presumably larger SATA drive you'll be putting in. But yes, both options are possible.

Hello,

Thanks again and again for all I learned here, I was able to replace the dead internal 3TB hard disk with another regular hard disk, I saw many guides else where but the adhesive replacement guide with the steps to test the machine was straight and easy to follow...

Now about the machine with only normal 3TB that I want to replace with SSD 2TB but I read as much as I can trying to decide which brand to use but I am lost, between Samsung which seems the best option yet it has some problems with the TREM to OWC 3G and others like Crucial and WD Blue, SanDisk...

It is not about the cost or the best performance at all, but this machine is my vault, my laboratory and it holds all my data from personal to work, I can handle the extra data externally and I want an SSD that I can rely on, which way should I go? I know there is no single best answer but my decision will come after your opinion...

thank you again...

Before you alter the Fusion Drive’ed system you really need to break the Fusion Drive set following this guide: How to split up a Fusion Drive.

Frankly I would just move the good 3TB drive over to the Fusion Drive’ed system.

As far as your replacing the HDD to a SSD you can use any 2.5” SSD. But if you really want performance for video editing or VM sessions you may want to look at getting a large blade SSD instead of the SATA SSD drive.

You really need to use the OWC thermal sensor if you want the system to last. Fan control software is not that good I’ve seen to many systems killed by it.

Hi,

You know what its better to upgrade both imac with the ssd storage its better and durable than swapping it. Then buy HDD enclosure to transfer or make your drive as an external.
