I have EXTREME PRO 1TB model SDSSDE61-1T00. I am having a very annoying problem, files are coming out up to 10x bigger on the SSD than they are on the computer or on any other brand external HD. For example, I am trying to copy a 24 GB file and its telling me it cannot copy it because it needs 250 GB more free space. I have a few files on there now that are less than 200 GB anywhere else and are taking 750 GB on my SSD.
The files are CELLEBRITE PHONE EXTRACTIONS and have many subfolders and hundreds of small files. I am using default EX-FAT. Should I be on NFTS?
This is extremely frustrating and preventing me from getting work done. We paid for a 1TB SSD which right now is acting like a 100GB SSD.
Hi @bradpan75,
In order to resolve your issue, I would request to to format drive in NTFS file system.
So NFTS worked great. File sizes are correct, and transfer speed is much better. The file folders I am copying have 1000’s of small files, so NFTS was crucial for this.
Hello,
This is to inform you that you can use NTFS format to transfer the files and it will not effect your effect.

I bought the SSD mainly to archive my Dell XPS desktop and my new Dell Inspiron 2-in-1 laptop. However neither of those recognise the drive.
If I plug the SSD into my ancient Acer Aspire it works great. Also works just fine with my Samsung S10 phone.
I read somewhere that maybe the Dell USB ports weren’t providing enough power for the SSD and the advice was to get a powered USB extender, which I did. Still didn’t work.
I also have 256GB Sandisk USB stick, that works in every port on all machines, so they aren’t faulty presumably.
Any ideas what is going wrong please?
This is an issue with cluster size. Modern hard drives divide storage space into “fixed-size bins” (technically known as clusters). Your SSD is currently formatted as exFAT by default; to prioritize speed, this format uses very large bins (for instance, a single bin might hold 1,000 KB). However, the files you extracted from your phone (Cellebrite data) consist of tiny items. Once you place an item—no matter how small—into a bin, that bin becomes “locked” and cannot hold any other files. Consequently, a tiny 1 KB file ends up occupying a massive 1,000 KB bin, wasting the remaining 999 KB entirely. [Also read - exFAT vs. NTFS: Differences & Which One to Choose ]
The solution is to reformat the drive to NTFS.
1. First, copy all files from the SSD to your Windows computer’s internal drive. (Don’t worry; once copied to the computer, the data will immediately revert to its normal 200 GB size.)
2. Reformat the drive:
• Right-click on your SanDisk SSD on your computer and select “Format.”
• Change the “File system” dropdown menu to NTFS.
• Click “Start” and wait a few seconds for the process to complete.
3. Copy the files you backed up to your computer back onto the SSD.
