I find that deleting lot of larger files from my 1tb Samsung T7 SSD takes much longer on my M1 Pro Machine compared to my Intel Machine. Is it related to the M1 Chip or could it be something else?

I can’t remember for random speeds but for sequential speeds, I believe my 2017 iMac is about 20-25% faster than my M1 Mac mini.

Is anyone willing to test the new HyperDrive Next USB4 enclosure ($120)? Supposedly, essentially the same as TB4. 😏

Sure, if you were sending them out to test.

I passed on the HyperDrive and bought an Acasis instead. I put in a Silicon Power 4TB SSD. Here's the DiskMark test with my MBP M1 Max. It's definitely the fastest drive I have by a long shot. It even beat my WD Black 4TB drive in a Konyead enclosure.

Interesting. I think there's a problem with AmorphousDiskMark and WD 850X 4TB. I get the same low write results.
When I test in Blackmagic Disk Speed Test and AJA System Test I get about 2800 mb/s in both read and write.
I've done some real world tests writing from the acacias TBU405 to the internal disk and it's blazing fast.

I have a Lexar SL600 1TB external SSD which supports USB 3.2 Gen2. Connected to my MBP 16' M1 Pro and the connection speed was right at 10Gbps.

Speed test result looks normal as well.

Unfortunately, I failed to test the WD Black with Blackmagic, and now it’s used as a Carbon Copy Cloner disk so it’s set to read-only. 🤔

I ordered one of the Acasis (JHL7440) enclosures. Any recommendations on current 4TB SSD? There are so many options. My use case is a large Apple Photos library on 14” M1 Pro.

I just searched for "JHL7440" at acasis.com, and got five results, none of them specifically labled as JHL7440. So I'd suggest you go to their website, find your specific product, and check the SSD recs they give at the bottom. [If you don't see any, email Acasis.]

As an example, here is one of the hits. For this one, the 990 Pro is probably the best best, since it is avail. in 4 TB, and should give great performance (plus it's currently $360 on AZ, as comparared with $503 for the Seagate).

I got the SN850X when it was cheaper. Been working great on my mac. I have 3 Acasis externals and using a 4 TB SN850X, and two P31Gold 2 TB. All working flawlessly,

Thanks! I went with the 990 Pro and will post results. My Acasis model is TBU405 with the fins on top, but without fan.

OK, this is interesting. I am considering buying a MBA/16GB RAM/512 SSD/, as a transition machine, to sort of replace my late 2018 MBP i9/32GB RAM/VEGA20 – and my thought was to keep all my heavy video and capture one stuff on an external OWC TB3 Express 2TB SSD. That way, I can stick with 512GB SSD on the MBA. However, if the USB ports are slower than on my MBP 2018, that won't work, as it will be too slow.

Does anyone have an external SSD that sustains read speeds of around 1.000 Mb/sec, that can test this? (Samsung T7, Sandisk Extreme Pro etc.)
I use a Sandisk Pro 2 TB I bought in Costco for 110$. It gets me 1000-1100 MBps. I have a thunderbolt quad slot m.2 enclosure that is 40 Gbps.

Migrating to a M2 pro Mini and have 2 Samsung 860 EVO 1TB that I want to connect via USB 3.1 gen 2. I purchased the OWC Mercury Elite Pro Dual Mini and had all of the speed (reduced to 5Gb/s) issues in this thread. The OWC technical support acknowledged the chip incompatibility and issued a RMA. I read some good references to Oyen and purchased this, connects at 10Gb/s, bonus it has a hub.
