Tablo DUAL’s internal memory is actually EMMC which is a bit different than what’s in a USB Flash drive.
Despite the faster speeds of today’s Flash Drives, we have tested them over the past year with both new & old Tablo units without much success.
That’s why we continue to suggest USB connected hard drives. It doesn’t matter if they’re 2.0 or 3.0 or if they’re SSDs as there’s no speed reason to spend more $ on an SSD vs. a regular spinning drive.
If you like the ‘no moving parts’ aspect of an SSD and have the cash to spare, go for it!
