It depends what you mean by better. If you purely mean bigger (as in more), then 1Gb is better. However, if you mean reliability, then there is no inherent difference in reliability between sizes, only manufacturer. Western Digital, Samsung and Seagate are 3 reputable manufacturers, but it's best to go by reviews.
Well, 1 gigabyte is 1024 megabytes, so 1GB is better.
No 1gb is 1000mb roughly
No its not better, a Gb is amount to 1024 Mb :P
1GB has way more memory. 1GB is 1000 MB. so 512 MB is about half of 1GB
1GB is bigger than 1MB
1GB is 1,000 MB which is smaller than 1TB which is 1,000,000 MB (or 1,000 GB)
About 1000.
1024mb = 1gb
1GB = 1024 MB 1MB= 1024 KB So 1GB= 1048576 KB
1024mb (megabits) = 1gb (gigabits)
The answer is obvious, 516 MB.
1024MB=1GB
