SSD vs PSSD

Some of you might wonder the differences between PSSD and SSD. In this section, we will compare them from usage, performance, physical size, and interface respectively.

PSSD vs SSD in Physical Size

Since PSSDs are removable and easier to carry around, as far as physical size is concerned, they are smaller and lighter. The standard sizes of SSDs are 2.5 inches, while the PSSD is compact enough to fit in your pocket.

PSSD vs SSD in Interface

Usually, you can plug a PSSD to your computer through the USB port, while SSDs connect through SATA, PCIe, or M.2 interfaces.

PSSD vs SSD in Speed

In terms of performance, the speed of SSDs depends on the interface type. For example:

• SATA SSDs’ speed ranges from 300 MB/s to 550 MB/s.
• NVMe SSDs can get up to astounding speed from 3000 to 3500 Mb/s.
• PCIe SSDs copy files from 3000 MB/s to 10000 MB/s, or even more.

The data transfer speed of a portable SSD is determined by the USB specification. For instance, the speed of a PSSD with a USB 3.2 Gen2x2 port can reach up to 1800 MB/s and 2000 MB/s, which is much faster than the original SSD.

PSSD vs SSD in Usage

Portable SSDs usually serve as second data storage devices that save copies of large files or backups of important data. They are compact, lightweight, and satisfy your need for data mobility. SSDs work as internal storage devices on your computer. For those who are still using mechanical hard drives, upgrading HDD to SSD can significantly speed up the computer.
