I lost my jewel QE55Q8C as Samsung ditched all parts to a two year old tv.
I bought a used MU9009 ( Samsung LED 9-series, Tizen3) and used a cheapo USB Flash memory for recordings. The performance was awful, lagging as hell.
The drive was Kingston DataTraveler SE9 G2 64GB

After reformatting the NTFS partition with 4k sector size (maximum) and 64k cluster size the performance is awesome again.
