Question 1

Which cache is correct for the 10TB WD100EFGX?  The title says 512 and the drive selection button says 256?

Accepted Answer

Per ChatGPT, For the WD Red Plus WD100EFGX 10TB NAS hard drive, the official cache (buffer) size is 512 MB according to multiple current specs listings and reseller datasheets.  ￼

However, it is possible to see listings online claiming 256 MB cache for the same model — that’s most likely due to incorrect listings, seller errors, or confusion with similar part numbers (e.g., WD101EFBX is another 10 TB Red Plus SKU that uses 256 MB cache).

Hope that helps
