Hi. I have MacBook Air 2 2O22. I bought a disk WD black P50 which should have a read and write speed of up to 2000MBs. But I start Black Magic speed test and result are under 1000MbS. where can the problem be?.

That is about right for that SSD.

 
Thanks. I never thought of that :( I was choosing a fast disk
Is it slowing what you’re trying to do down or you just want a higher number on the benchmark? I wouldn’t spend money just to get a higher number, but if it’s actually slowing your work down, then get something faster.

yes, it was slow - I need to quickly copy a large number of photos from the SD card to disk and then from it to lightroom and work in it. This drive was as fast as my older drives, I bought a Lacia and the speed is different.

That's a good outcome. Which drive did you buy?
 
as a FYI, M series macs cannot use USB C 3.2.2 Gen 2, even the new M4s. So no other drive saying "20 GB/s" will work either.

If you want faster, you will need TBolt. Its prob too late to return, but you could DIY a 1TB Tbolt 4 drive for under $150.. speeds are 2500-3000 MB/s. A baisc prebuilt 10 GB/s 1tb drive is half that, $70-80,

USB 3.2 Gen 2 2x2 drives will work, but not at 20GB/s, they will fall back to 10GB/s.
