This situation can be described with that famous saying, "you can't have your cake and eat it too".
If you want instantaneous playback on the first time, every time, you need to disable disk spindown and have them constantly spinning 24/7.
If you're worried about your HDDs' health, constantly spinning them up and down destroys them faster than just having them always spin constantly.
If you're worried about electricity costs, you'll have to do the math based on where you live and the kWh cost you need to pay.
As an example, if you pay $0.15 USD per kWh, and your Synology unit on idle uses 35 watts, that's 0.035 kWh (35 ÷ 1000) and will cost you $0.00525 USD (.035 × .15) per hour to keep idle. If you're to keep it idle for a day, you'll pay $0.126 per day. If you'll keep it idle for a year, you'll pay $45.99 per year. To follow this math, just replace the currency with your own and your own costs.
Also, if you really don't want the HDDs to be spinning 24/7, you can compromise and only have one or two drives spin while the rest spin down using an OS like Unraid. With how Unraid works, it allows you to have all of your video files on a certain disk(s) that you can keep spinning 24/7. Unraid will allow you to spin the other disks down. This way, you get fast access to the media in your Jellyfin library while also having all other non-related disks not spinning.
