The Evolution of Portable SSD

The external SSD drive, also known as a solid-state disk (SSD), has a rich history of technological advancements. Initially, SSDs were similar to SSDs, but later, SATA Express and M.2 interfaces were developed to enhance their performance. In the late 1980s, Zitel, Inc. introduced DRAM-based SSD products called "RAMDisk". SanDisk Corporation revolutionized the industry in 1991 by releasing the first 20 MB SSD for IBM ThinkPad laptops. In 2009, SSDs saw significant improvements with the introduction of a PCI Express ×8 interface by OCZ Technology and the announcement of an SSD with 6 Gbit/s speeds by Micron Technology. Despite their impressive performance, SSDs can experience data leakage over time without power, but this issue is mitigated by the use of 3D TLC NAND-based flash memory.

Storage Capacity

Think about how much storage space you'll need. External SSDs typically range from 250GB to 8TB, but the most common capacities are 500GB and 1TB. Here's a guideline to help you decide:

  • 250GB-500GB: Ideal for storing essential documents, photos, and casual gaming.
  • 1TB-2TB: Great for storing a sizable photo and music library, along with documents and games.
  • 4TB and above Ideal for professionals working with large video or design files.


Speed is a significant advantage of external SSDs. Look for models with faster read/write speeds, measured in megabytes per second (MB/s) or gigabytes per second (GB/s). Here's a general guide:

  • 500MB/s - 1000MB/s: Suitable for everyday tasks, including document editing and browsing.
  • 1000MB/s and above is Ideal for demanding tasks like video editing, gaming, and professional applications.


Most external SSDs connect to your computer using a USB cable. The most common types are USB 3.0 (also known as USB 3.2 Gen 1) and the newer USB 3.2 Gen 2 (also known as USB-C). Here's a breakdown:

  • USB 3.0: Offers good transfer speeds, but is slower than the newer options.
  • USB 3.2 Gen 2: Provides significantly faster transfer speeds, ideal for maximizing the potential of your SSD.

Form Factor

External SSDs come in various sizes and shapes. Consider portability and durability based on how you'll use the drive.

  • 2.5-inch SSDs: The most common size, offering a good balance of portability and storage capacity.
  • Pocket-sized SSDs: Highly portable and ideal for carrying around, but may offer less storage capacity.
  • Rugged SSDs: Built for durability and can withstand drops and extreme temperatures.
