Does it support 18TB and 20TB hard drive? Or just 16TB? And does it support an enterprise 7200RPM hard drive or just 5400RPM hard drive?
My generic answer to all questions about HDD's: Which SATA HDD (Internal/External) to get for these players and how to format? This must be the question asked most for any media player. My cut & paste answer is generic for all brands and models: - If you like absolute silence: Any 2.5 drive using an 2.5 => 3.5 adapter will do also for Internal. A SSD can be used that way too obviously but is regarded an overkill by me as it offers no substantial additional advantages. - A bit cheaper per TByte is using any low speed version 3.5 HDD. Cheaper/slower models is better in most cases. Player performance will be identical and less energy => less heat => above all less fan/drive noise! - The cheapest is buying an External USB drive even for an Internal HDD by extracting the build-in HDD from that one. That is what I usually do myself. Formatting using a W10 PC SATA attached with GPT and NTFS using all defaults will do the job. Don't use FAT32 (no big file support) and no exFAT (less robust as not intended for HDD's but for sticks/cards). Make very sure there are no second or hidden partitions on it as Android likes it plain and simple (it does not process these options). For Apple and/or Linux PC users a good alternative is using EXT4 then. As far as I understand the biggest HDD supported is 16 TByte as using a 32-bit register for LBA addressing with 4K Physical Sectors only works up to 17,6 TByte. Practical testing confirmed this limit. The maximum SATA HDD according my theory and others practical testing for Android is 17.5 TByte (=16300 Gigabyte). https://www.futeko.com/newforum/index.php?topic=576 Warning: This limit is NOT present using a W10 64-bit PC or via USB which may be confusing.
