What are maximum capcity and transfer rate for IDE/STA drives?

I am curious to what the max hard drive size (in GB) is for IDE and SATA, and what is the transfer rate maximums for IDE and SATA. I need sources for all information 🙂
 
Well, I believe 750 GB is the biggest for a 3.5", We haven't hit the limit though, and I doubt we'll know for a while.
 
I know there is a limit for the IDE interface, but what is it? 400gb, 500gb? I need some proof!
What is the largest SATA hard drive available now?

I highly doubt there is a limit. All the IDE interface is doing is sending info back and forth, it has nothing to do with the actual capacity of a drive.
 
An important note is the 750gb drive uses verticle platters instead of horizontal. Verticle gives you more "room."

are you asking what the largest drive size the ide interface will allow or are you asking what the sustained transfer rate of ide is, like your topic suggestes. the ide limit is 100MB/s or 133MB/s that is MAX sustained transfer, where as most drives actual sustained transfer rate is about 40+ MB/s or so. SATA drives on the other had have a max rate of 300MB/s or 150MB/s depending on whether it is SATA, SATAII, or SATAIO
 
You can't scientifically state that there is a true limit to hard drive storage because there are always going to be some new, crazy techniques for somehow breaking these limits.

that platters themselves are not perpendicular but the actual bits on the platter are arranged perpendicular to increase density.

Why would IDE or SATA have a particular size limit in drive space? 😕

That's what I was wondering, it's just an interface, nothing more.

Maybe he's thinking of the file system? NTFS has a limit, but it's so large it'll be long outdated before its limit will ever be reached.
 
Maximum Sizes on NTFS Volumes

In theory, the maximum NTFS volume size is 264 clusters minus 1 cluster. However, the maximum NTFS volume size as implemented in Windows XP Professional is 232 clusters minus 1 cluster. For example, using 64-KB clusters, the maximum NTFS volume size is 256 terabytes minus 64 KB. Using the default cluster size of 4 KB, the maximum NTFS volume size is 16 terabytes minus 4 KB.

Because partition tables on master boot record (MBR) disks only support partition sizes up to 2 terabytes, you must use dynamic volumes to create NTFS volumes over 2 terabytes. Windows XP Professional manages dynamic volumes in a special database instead of in the partition table, so dynamic volumes are not subject to the 2-terabyte physical limit imposed by the partition table. Therefore, dynamic NTFS volumes can be as large as the maximum volume size supported by NTFS. Itanium-based computers that use GUID partition table (GPT) disks also support NTFS volumes larger than 2 terabytes.

That's not quite true. It's an interface standard, part of that standard is the number of address bits available. There is a cap, based on how many different addresses 48bits can handle, and the size of those individual locations, but this cap is so large that it can be ignored for the time being.*

* I think the cap comes out to being 9 Exobytes
