If you're planning on buying a cheap USB drive, think carefully. Instead of choosing slow, traditional USB drives, switching to a USB SSD (also known as a stick SSD) is a smarter choice. These devices have a compact design like a regular USB drive but offer significantly faster speeds at only a small price difference.
Why are USB SSDs superior to traditional USB drives?
Technically, all USB drives use NAND memory chips, similar to SSDs. However, the component quality and transfer speeds on typical USB drives are usually among the lowest on the market.
- Actual speed: Most traditional USB drives only reach a maximum speed of around 150MB/s. When copying large files, the speed often drops below 100MB/s due to insufficient cache memory.
- Durability: Because they use inexpensive memory chips, USB drives generally have much lower write/erase durability compared to SSDs.
- New technology: USB SSDs use high-quality NAND chips and the NVMe protocol, allowing speeds up to 10Gb/s (approximately 1000MB/s) . Thanks to their large cache memory, these drives can maintain high speeds even when transferring hundreds of GB of data.
For example, the SK Hynix Tube T31 is essentially an M.2 NVMe drive with hidden DRAM cache inside a compact enclosure. It can maintain an average write speed of 600MB/s even when copying a massive 450GB file.
Price is no longer a barrier.
The biggest advantage of USB SSDs today is that their price is now very close to that of traditional USB drives.
-
Approximately $18 : Equivalent to about 460,000 VND
-
Approximately $27 : Equivalent to about 690,000 VND
-
Under $40 : Equivalent to less than 1,020,000 VND
For just over 200,000 VND more, users can own a device with speeds comparable to a portable SSD but with the added convenience of being able to attach it to a keychain.
Should you buy a USB SSD instead of a portable SSD?
In many cases, USB SSDs are a better option than traditional portable SSDs:
- Compact and lightweight: No cumbersome cables needed, plugs directly into the computer.
- Equivalent performance: Many models, such as the TEAMGROUP X2 MAX, offer speeds of 1000MB/s, comparable to popular portable SSDs, but in a size no bigger than a fingertip.
- Value for money: Some high-end USB SSDs are even cheaper than older high-end USB models while offering twice the speed.
Conclude
The advent of USB SSDs has rendered traditional USB drives obsolete. The only reason to buy a traditional USB drive now is when you only need extremely low capacity (under 64GB), as USB SSDs typically start at 128GB. With the current need for large-scale data storage and transfer, investing in stick-type SSD technology is a cost-effective and long-term investment.
