Storage Capacity and Value
The SanDisk E30 offers 2TB of storage compared to the Ultra's 256GB - that's 8 times more space. While the E30 costs $87 more, you get significantly better value per gigabyte and room for thousands more files, photos, and videos without constantly managing storage space.
Performance and Speed Differences
The E30 Portable SSD delivers read speeds up to 520MB/s, while the Ultra USB 3.0 tops out around 130MB/s. This means the E30 transfers a 4GB movie in about 8 seconds versus over a minute with the Ultra drive. For large file transfers, video editing, or running applications directly from the drive, the SSD is dramatically faster.
Build Quality and Portability
Both drives are compact and portable, but the E30 features a more durable design with better shock resistance. The Ultra drive has a traditional plastic construction that's adequate for basic use. The E30's premium build quality justifies its higher price point for users who need reliable performance on the go.
