I’m going to get flamed for this. And I don’t say it to be confrontational, but for me, I think that 1 uSD slot is a short term personal implementation problem. Here is why I say that.
(Hypothetical) Let’s say you did have 2 uSD cards at 128G filled with your favorite high rez music and plugged into your TOTL DAP with 2 uSD slots. You want to have all your high rez music with you. You want to access it at the touch of a fingertip. You are happy for this moment in time.
But Oh Crap… They just released all of Starland Vocal Band’s 22 albums in remastered High Rez. You have to get them all. Now you’ve blown your 2 uSD cards capacity and have to buy 5 more so you can hear Skyrockets In Flight Demos 1-5 from the remastered version.
I think the best solution would be to have the ability to swap cards with a scan time that is negligible. Just carry 2, 3, 10, 50 uSD cards with you. And swap out any time you want.
From a price/performance aspect, 128G uSD are 40 Dollars today on amazon, and 200G are 64.87. I find that as my collection grows, so do the size of the uSD cards. And I’m happy filling one up. Then getting a bigger one and filling it up. While sending my older smaller cards to other DAPs.
Remember that at one time, dual disc drives in computers were all the rage. Dual uSD slots was a good thought. As long as the interface wasn’t kludgy and the scanning was fast, I’m all for it. But if there were problems implementing it, such as UI doesn’t merge pointers into one big library, or scanning is an issue, or it kills battery life, or any number of other issues, then I would want one slot that is well implemented and fast.
OK. Dissenting opinions welcome.
