Get a thunderbolt drive caddy and boot from external Thunderbolt disk. Refreshed an old iMac this wayz

I did the same. OS and apps on a cheap 240GB Thunderbolt SSD. Everything else on the internal 1TB spinning disk. Now it’s fantastic.

I pulled the screen off and installed an SSD. Easy to do

Any links to a tutorial on how to do this? I'd love to do that but also don't want to crack the screen in the process.

Something sounds wrong. I have an older 21.5 with the first generation 1 TB fusion and it is not at all slow.

First generation 1TB fusion drives had 128GB of SSD storage. 2017 and 2019 1TB fusion drives have 32GB of SSD storage [1], which is basically just enough for the OS and a couple of apps if you are lucky. People are not exaggerating when they say Apple hardware are regressing, not progressing.

Putting/letting Jony Ive on designing the new campus is one of the dumbest things Apple has done. Effectively dereliction of duty.

Now that he's back on task, I'm holding my breath that there are some mea culpas in the next round of hardware updates. If there aren't some significant quality improvements I'll probably still get a new laptop, but I'll be selling my shares.

That explains it. I hadn't actually used one before purchasing it but had used the previous generation model a few times.

The size need only be proportional to the amount of hot data. And realistically, it need only be proportional to the amount of hot data that's randomly accessed in small chunks, because that's where the bulk of the improvements will come from.

I wonder why the performance ain't so great. I bet 32GBytes is in principle more than sufficient.

That's quite the opposite of my experience where only very cold data is not SSD-level performance. Do you have anything like anti-virus software which might be interfering with the HSM mechanism?

In my experience most of what I end up needing ends up cold. Even XCode builds take forever on it due to the slow storage.

Now I’m wondering how to get visibility into it. I work with a ton of repos and never see this - it’s usually just things like old VMs.

I have the 5k iMac with slow hard drive. I ended up getting a USB3 SSD and booting the system from that drive. Works great. much faster.

If it's less than a year old, it's under warranty. Take it in (or send it in) and make Apple look at it. It should not be that slow.

So you couldn’t just by an SSD external drive and boot off of that?

A $3k desktop for which you need to buy an external drive. At some point slavishness to the Apple brand must have a breaking point.

Not wanting to start a fanboy war but I am a big believer in the right tool for the right job at the right price. For $3k I could build a monster PC with a stunning screen.

If you’re buying a “$3000” iMac you’re not buying one with a fusion drive....

Canadian price for a top-end 27" Retina iMac is $3079, and has a 2TB Fusion drive standard. The 512GB SSD option is $120 more than the Fusion drive.

A quarter of the storage at a premium price isn't exactly appealing to a lot of people, regardless of how much faster it may be.

You know there is a way that you can configure what you want for your budget....

I maxed out the CPU and got a lot of RAM, I assumed the drive would have enough cache that I wouldn't notice the spindle aspect.

And now that you see it isn’t the case after that you couldn’t just say “my bad” and spend the < $200 for an SSD drive?

I think the SSD would have been $500 more, which I would have happily paid if I had realized how poorly the fusion drive would perform.

So you would have been willing to spend $500 morethen but not spend much less and buy an external drive now?

I’m not unwilling to buy an external drive, but I’d rather have a better internal drive.

Isn't the point of an iMac the fact that it's a clean, uncluttered device?

If you are willing to accept separate components, you can buy much cheaper hardware.

Seeing that hardly any reputable company sells 5K displays anymore besides LG, the monitor itself is worth $1300. The cheapest 5K iMac is $1800. You’re not going to find computers “much cheaper” than $500 that match the iMacs specs.

So now you have to carry an external HDD around with you and plug it in every time you want it to boot up?

We're talking about iMacs. In case it's not clear, that's a desktop system not a portable one.

Ah. I got mixed up. Thanks.

They only put the anachronistic drives in iMacs which are desktop computers. You could leave a fast Thunderbolt 3 SSD permanently attached, and it would perform like a 2019 computer.

Are you carrying around an iMac with you? If you are, the drive is the least of your issues.
