NTFS's robust file permissions control puts it ahead of exFAT for an internal storage device, but exFAT's tolerance of hot-plugging make it a definite choice for USB-connected storage. The reason to use FAT32 is universality (even HDTVs read it) but many devices (such as my phone) cannot read exFAT.ĭo you mean in addition to the reasons discussed in the article I linked to? This is the final summary:īetween exFAT and NTFS, it's almost a draw. Probably exFAT has lower space overhead, but I don't have numbers. Whereas NTFS is a well respected and widely supported filesystem. To my mind, exFAT is a unsophisticated filesystem for use with SDXC cards and when FAT32 is appropriate but you want to have > 4GB files. Although all my other external drives (spinning disks) came preformatted with NTFS with 4kb.ĭo you have any idea why? I would like to know. This external SSD came preformatted with exFAT also. The article I linked to suggested that for external drives exFAT is somewhat preferable. Quick should be fine unless the SSD contains bad spots, which seems unlikely.ĭo you intend to use the drive on machines with a different OS? If not, why not use NTFS? Or a utility like AOEMI.Ĭan I do quick format or must I do a full, slow format? You can use the format or diskpart command to format the drive. If you're storing a LOT of smaller files, definitely try the smaller cluster for more efficient storage. Larger cluster size typically improves performance when storing large files, but leaves a lot of slack space when storing smaller files. Barely understood the questions, gave contradicting answers, etc. I spent almost an hour in chat with Sandisk support today asking about how it was formatted out of the box and related questions, but they were useless.
SAMSUNG PORTABLE SSD T5 FORMAT FAT32 WINDOWS
What do you think? Should I use the Windows command line format utility to do this? For example, a command like this:įormat g: /FS:exFAT /V:Sandisk Extreme SSD /A:4096 I am thinking that I should reformat it to exFAT with an allocation unit size of 4kb or 8kb. By the way, I already read this and it indicates that for external drives exFAT is probably the way to go: I have a Western Digital My Passport 4tb portable external HD (spinning platters) that has NTFS and 4kb allocation units.
I care more about making efficient use of the space and not wasting it than I do about trying to get the very last bit of performance. I will only have data on it and the file sizes range from 1kb to 80mb. Is chkdsk reporting this accurately? That sure seems very large. It has exFAT file system and when I ran chkdsk on it says that the allocation size is 1,048,576 bytes (1mb). Yesterday I bought a Sandisk Extreme 2tb external SSD for use with my Win10 HP Spectre x360 ultrabook (has internal 256gb SSD C: drive).
