iMac Pro

[kcrossley]

I need to get a few 4GB external SSDs for my Late 2017 8-Core 3.2 iMac Pro. I want to get the fastest external SSD I can support. I'm currently trying to decide between a Samsung T7 SSD with 1050 MB/s or a T9 with 2000 MB/s read speeds or maybe even something I haven't even considered. Suggestions appreciated.

What's the maximum transfer speed I can expect from my iMac Pro with Thunderbolt 3 ports? I think it's something ridiculous, like 40 Gbps.

Thanks!

WD PCIe-4.0 NVMe ads claim roughly seven-fold the T7 speeds, but you will need an appropriate enclosure.

The fastest the iMac Pro supports is Thunderbolt 3. It doesn’t support USB4, so the best non-TB speed it can achieve is USB 3.2 Gen 2 10GB/s.

Shopping for a faster external SSD

Given that Thunderbolt SSDs are unusual and expensive, should you buy a USB4 model that claims to be compatible with Thunderbolt? Watch out for the traps.

How to evaluate an external SSD

Check its protocol support and expected maximum transfer rate, then whether it supports SMART indicators and Trims with APFS. Finally check its real-world performance.

Last Week on My Mac: Why good external SSDs are faster with Apple silicon

Why an Intel Mac’s up to 40 Gb/s from Thunderbolt 3 is less than an Apple silicon Mac’s up to 40 Gb/s from USB4, and how you can benefit from it.
