As of this writing, the new V100 is available via:
Price estimate: $89 - $149 USD. Avoid any listing under $40—those are just flashing tools that cannot perform the "double space" function.
Use Windows Disk Management (built-in):
Or use AOMEI Partition Assistant or EaseUS (free versions).
It is important to manage expectations. Doubling space via compression and virtual linking comes with a slight CPU overhead from the V100's processor.
Verdict: For large media files (video, audio, disk images), the slight speed penalty is unnoticeable. For running operating systems or databases, the penalty is minor but present.
Instead of risking your files with a "space doubler" tool, try these safe and legitimate methods:
1. NTFS Compression (Built-in to Windows) If you want to fit more files on a drive safely, use the built-in Windows compression:
2. Check for "Fake" Drives If you bought a USB drive that seems too good to be true (e.g., a 1TB USB stick for $10), check it with a free tool called H2testw. It writes data to the drive and reads it back to verify if the drive is lying about its size.
3. The "Shoe Leather" Method If you have many small SD cards (like 4GB or 8GB cards from old cameras), it is safer and faster to simply buy a single, large-capacity card. Storage is very cheap nowadays—a 64GB or 128GB card is a reliable investment compared to risking data loss on old hardware.
Unlike traditional compression (which requires software), the V100 writes data in a denser bit-packing format at the hardware level. By changing the ECC (Error Correction Code) parity block size, the tool frees up approximately 40-50% more usable blocks, effectively doubling the logical capacity of a 32GB drive to 64GB.
The tool operates by manipulating how the host computer reads the storage device's allocation tables.
When you run SData Tool, you typically select your drive, click a button (often labeled "E-Compress" or "Double Space"), and wait for the process to complete. The software claims to use a proprietary compression algorithm that allows the drive to store more data than its physical limit suggests.
The Theoretical Process:
The headline sounds like magic, but it’s actually applied mathematics and flash management. Here is how the SData Tool V100 double USB or SD card space new feature works:
