Since I did the whole series of benchmarks on a MacBook Pro 2021, I was curious what the performance is on the MacBook Pro 2017 Intel Mac, so here’s the test series
| MacBook Pro 2017 Razor Thunderbolt Dock MBps (R/W) | Full | Connection | Sequential QD32 | Rand 4KiB QD32 |
| Onboard 1TB SSD | 80% | NVMe | 2,745/389 | 441/60 |
| ThunderBay 8 RAID10 8 x 12TB Toshiba | 98% | Thunderbolt 4 40GBps | 763/286 | 9/5 |
| Rocketstor 5212 Seagate X16 16TB x 2 | 93% | Thunderbolt 4 to 2 Adapter Thunderbolt 2 10Gbps | 131/57 | 3/6 |
| Startech SATA2USB3 Samsung EVO Pro 1TB | 74% | ASMT 1051 5Gbps | 303/263 | 47/23 |
| Startech SATA2USB3 Samsung EVO Pro 512GB | 12% | ASMT 1051 5Gbps | 288/281 | 41/16 |
I’m not really sure why the benchmarks for the ThunderBay and Rocketstor was so bad, but I suspect being 98% and 93% full means lots of disk fragmentation. I can’t really clean these up, but I think the sequential is probably closer to the mark for their performance. Certainly getting 763MBps read from a RAID10 array seems good as we should be getting 4 disks at 200-300MBps each if there was no overhead, but the random is pretty bad.
