I thought I would try a 4TB Samsung T7 shield, external SSD. I understand they are very reliable, and while are not TB, should get about 800 MB/s speeds, which I figured would be a good compromise for my needs. At $300, it seemed like an economical solution vs. a 4TB NVME stick like the SN770 in an Acacis TB enclosure.
I received the drive and was surprised to see that the Read speeds were only about 300 MB/s (measures with both BlackMagic and Aja Speedtest). The write speed was as I expected, about 800 MB/s. Is this normal, or did I get a bad drive?
It's connected to a maxed out M2 MBA and I tried different ports, used a TB4 cable, reformatted it as APFS, etc.. Any thoughts on why it is so slow? It's even slower than a 2TB T7 touch I had tried out. I thought the T7 Shield was the fastest USB SSD Samsung made and was improved over the standard T7 and T7 touch.
