Storing DSD/PCM files and playing through a DAC

Folks,
Over the past few weeks, I have ripped my 140+ SACDs to .dsf files, using a Sony blu-ray player. I want to know a couple of things that you all prefer/have experience and would recommend:

1. Type of drive (HDD, SSD, NVMe, etc) to store the files for playback via DAC

2. If the player/DAC has a USB 3.0, would you connect the drive directly to the player/DAC, OR use a laptop and connect the laptop out to the DAC's USB input?

Currently I am using a Oppo UDP-205 as my player/DAC. But at some later point, I would like to rip my CDs also as digital files and play the files via a dedicated DAC. What software can I use, to keep the laptop near the DAC and control it via a app on the phone/tablet? Currently using foobar2000 to experience the playback of  .dsf files on the computer. Not yet attempted to connect the laptop to the DAC via USB. Also have got a few DSD albums that I have ripped, transferred to a flash drive and connected the drive to USB3.0 of the Oppo. Any advise?
