Which file system to use for a large (1 TB) external hard drive?

Question

I've got a 1 TB hard disk drive which is currently formatted as NTFS. I've recently learned about exFAT. I'm connecting this drive via USB. Which filesystem should I use for this large hard disk drive and why?

(I know exFAT requires a patch on Windows XP; this is not a concern.)

Answer 1

Since you're basically contemplating NTFS vs. exFAT, easy support for other operating systems doesn't seem to be a concern. I'd suggest staying with NTFS. exFAT is primarily meant for smaller volumes and slower devices where the space and complexity overhead of NTFS is an issue.

So I wonder what exactly do you plan to gain from formatting that drive with exFAT. It's in most ways inferior to NTFS anyway.

Answer 2

I'm pretty sure the "If it aint broken" philosophy is appropriate here. Do you really have a reason to start mucking about with filesystems? It's not as if NTFS has any major problems. Besides NTFS is a well-known filesystem that's been around for a while, whereas exFAT is the new kid on the block. This could cause problems down the line. For example if you were to ever use that disk on a linux system, you'd have far more support for NTFS than exFAT.

Answer 3

I would go for the ntfs too. Probably the least problematical and a quite good filesystem for large drives. If you want to tweak your hard-drive as much as it's possible try reading about formatting with the right blocksize for you.

Answer 4

Mac OS X 10.6.5 now supports the exFAT file system so that would not cause an issue on this drive. However, as has been pointed out many times here and everywhere else I have checked on the web, go with NTFS for large hard drives.

Answer 5

Although I'm not a pro - I would have thought for a large drive like that one you would want to go for exFAT for two reasons.

Firstly, exFAT allows for files to be up to around 16 EiB in size. NTFS also has file size limits that are larger than any drives that will be around for a long time. FAT32 has a max file size of 4GB - so depending on what kind of files you're going to be storing this would be a point to consider.

Secondly, exFAT is read and write compatible with OS X 10.6.5 upwards, but writing to NTFS is not supported. You never know - this hard drive might last longer than you having a Windows Computer...

Answer 6

I vote also for NTFS. It's a more developed format with which one can do more. See for example the Everything search engine in http://www.voidtools.com/, one of my most useful utilities.

Answer 7

DO NOT USE EXFAT FOR A HDD.it's ruined mine, it keeps losing files and data, and it's a world of hurt man, you don't wanna mess around with it. seriously. hell, I'd try ReFS before I went back to Exfat.

Do you have any Macs around? Plan on getting a Mac? If so, you may want to use FAT.

Your best bet may be to create TWO partitions, one FAT and one NTFS. Check out EASEUS Partition Master Home Edition (Free): http://www.partition-tool.com/personal.htm
