The 16” M2 Pro 16/512 is a little over 2K € NOS here in Slovakia incl. 20% VAT which gets refunded of course if you buy as a company.
When you mention the enclosures, @jerryy, for 40MPix files perhaps the 10Gbps enclosures are better because they are plenty fast IMHO and they spend less power (about 200mA as opposed to 500mA for the 40Gbps ones, for the ones I have measured), so when you run on battery that makes a difference. Fewer charging cycles, longer battery lifespan. Maybe they are plenty fast for 100Mpix files too, perhaps someone can chime in with their experience.
But talking about the 10Gbps ones, you may just as welľ buy a Samsung T9 which will be equally fast and maybe even cheaper, depending on what NVMe drives you happen to have at hand.
Also, you could connect the drive to a hub with its own power supply, but they usually charge the computer full time through the Thunderbolt port so if you are a purist and want to cycle your battery kindly, somewhere between 20-80% to prolong its life expectancy, the hub will disrupt your strategy. 😁 But do not despair, Acasis makes an eclosure/minihub which takes external power from an USB charger but does not charge the laptop so you can charge that extra to your heart´s content. Maybe automate that through a smart plug based on battery level events. 😁
A beautiful world we have, don’t we. Computers are great, they help us solve problems we didn’t have without them.
