Hello m8s. I bought a brand new iMac 21.5 4K with 1TB and this is slow like a hell. It has HDD instead Fusion drive and I’m pretty sure that’s the major problem. I want to ask if there is a way to make it faster. Or to sell and buy one with fusion is the only way ? Thank you all for your advices. I’m so sad

Of course it is. The day of the platter disk is gone particular the 5400rpm drive. And a 1TB Fusion is as worthless as it contains only 24GB of PCI-e Flash Storage. The 2/3TB models have 128GB of flash. Are you within the Apple exchange period of fourteen days?

Best option if not is cut your losses and either sell or run an SSD as an external boot drive via the USB port, cloning the OS etc to the external, and selecting it as the boot drive in System Preferences > Startup Disk. You can then use the internal as the backup drive.

If you go the way of another machine give FD a miss and go for nat least a 512GB SSD.

To be honest I bought it yesterday. But I don’t think so I can exchange it here in Greece... cause i didn’t bought from the official distributor. This was import from another country. But anyway. I’m thinking to sell it and buy a new with ssd from the beginning. Just wondering... if it’s an option to send it in official service here to change internal hdd to ssd ? Or this could not be in 21.5 2017 Model ?

If you don't want to go through the hassle of selling it you could simply use an external SSD via Thunderbolt.

If you bought a 2017 model you have TB3 which is super fast. You can either get SATA SSD which go to about 450MB/s and are relatively cheap these days, or a PCI enclosure with a PCI SSD which can go to 3GB/s more expensive but very fast.

I agree with this as being a good solution. I have been running external on my Macs for years without issue. Even on slower connections, like USB3, I got really good performance (400-450 MB/s) and excellent reliability with SSDs. I NEVER power down my Macs and never had any issues at all.

Even though the internal SSD drives run 1 GB/s+ speeds, the speed difference is barely noticeable to an SSD running half as fast in most real use cases.

Don't fret it, enjoy your new iMac and just pick up an external SSD. I have had good luck with Samsung SSD drives, but I am sure most well regarded brands would suit you fine.

Enjoy the new iMac!!! It is, in my opinion, the best deal in Apple computing right now....

The wife is running her 2015 iMac with a USB3 SSD and is very happy.

Non speed you can put internal disk like download,picture(if casual user) and so on.. Just put normal app in the external boot ..
 
Fastest, easiest, cheapest:
USB3 SSD.

Set it up to be your "external booter" -- ridiculously easy on a Mac.

Same situation here. Aside from the external SSD Drive I’m going to add 8gb Ram for a total of 16.

Thank you for the suggestions.
