how many documents is 1tb
1TB hard disk may store more than a million(10 lakhs) photos. that depends on quality of the image or photo. for example if the photos are High Definiktion this would use mor â¦ e memory. If the photo is JPEG, PNG etc. they use low memory. Any How you still can store atleast one million of photos. Because 1Tb is equal to 1024 GB or 10,48,576MB. to check any file or photo's memory usage just check it's properties. you may surprisingly see that no images can use atleast 1MB. in average.
