Underutilized "dedicated to ReadyBoost" USB drive

[chemazzo]

I inserted an empty 7.2 Gb USB drive in order to dedicate it to ReadyBoost but Windows 10 does not allow me to increase the maximum past 4094Mb "for optimal performance". I read of users connecting much larger drives for that purpose. What am I doing wrong/not getting? Is there a way to override/circumvent this limitation while also improving performance? TIA

Check the formatting of the card, by default and for full use should be NTFS. I use an 8GB that was formatted FAT32 for cameras and adding it in for ReadyBoost got reformatted by Win10 as NTFS and allowed choosing as full size, capacity shows as a red bar in File Explorer meaning all the space is in use. The actual figures for mine show 5.98 MB free of 7.39 GB.

Thought I'd mention that just this AM I took the Vostro 1510 I was using ReadyBoost on out of service and moved the SD card to an HP Notebook. I plugged the card in, used File Explorer to format it as NTFS [clean it] then in Properties set up ReadyBoost.
