Best Compact External SSD Under $150: Top 6 Picks 2024

Why Choose an External SSD?

External SSDs transfer data 5 to 10 times faster than traditional hard drives, have no moving parts to break, are significantly more durable against drops and shocks, run silently and draw less power from your laptop battery, and save hours when backing up large photo or video libraries.

At the $150 price point, you can secure a high-quality 2TB drive or a very fast 1TB drive that will outperform any traditional HDD or SATA SSD.

Kingston XS1000 2TB — Best Budget Option

The Kingston XS1000 offers outstanding value when capacity and price meet. Kingston sells the XS1000 in 1TB/$65 and 2TB/$110 capacities, which is considerably cheaper than the XS2000. You're getting USB 3.2 Gen 2 speeds up to 1,050MB/s and capacities up to 2TB.

Kingston's XS1000 was awarded with the Red Dot Design Award in 2024. The ultra-compact form factor makes it perfect for travelers who don't want bulk in their bag. The portable SSD comes with a 5-year limited warranty with free technical support.

Crucial X9 Pro 2TB — Best All-Around Value

At around $139, the Crucial X9 Pro 2TB costs around $40 less than the company's faster X10 Pro. This drive sits comfortably under budget while delivering reliable performance for everyday users.

The Crucial X9 Pro 2TB reads at 1050 megabytes per second and writes at 1050 megabytes per second. With IP55 water and dust resistance and drop-proof durability up to 7.5 feet/2 meters, it's durable enough to travel anywhere, and it's engineered in anodized aluminum with a rubberized soft-touch base in a compact 65 x 50 mm design.

Lexar SL500 1TB — Best for Performance Under $150

If you want lightning-fast speeds without spending more than $150, the Lexar SL500 1TB is worth hunting for a deal. The 1TB version is available for $124.99 USD. This drive brings USB 3.2 Gen 2×2 performance: read speeds of up to 2000 MB/s and write speeds of up to 1800 MB/s.

The SL500 can withstand drops up to 6.6′ and is MagSafe compatible, allowing it to directly attach to your iPhone 12 or later. The SL500 features Lexar DataShield 256-bit AES encryption software, is rated IP54 for dust and water resistance, and is drop-resistant up to 2 meters. It's a standout choice if your device supports the newer USB standard.

WD My Passport SSD 2TB — Best for Backup Software

The WD My Passport SSD 2TB is a perennial reliable choice that delivers standard USB 3.2 Gen 2 speeds (around 1,000 MB/s), AES 256-bit hardware encryption, and WD's included software handles automatic scheduled backups — which is genuinely useful if you want a set-it-and-forget-it backup solution without paying for cloud storage. At roughly $85–90 for 2TB, you're getting a solid drive well under $150.

The drive is compact and works natively on both Windows and Mac systems, making it a versatile choice for mixed environments.

SanDisk Extreme Portable SSD 1TB — Best for Ruggedness

SanDisk Extreme Go Portable SSD 1TB delivers up to 1050MB/s read speed and 1000MB/s write speed with ruggedized water & dust resistance, hardware encryption and memory zone file management. Up to three-meter drop protection and IP65 water and dust resistance mean this tough drive can take a beating, and it comes with a 5-year limited warranty and a durable silicone shell.

The handy carabiner loop lets you secure it to your belt loop or backpack for extra peace of mind. If you need a drive that can survive adventure travel, this is a strong pick.

Kingston XS2000 1TB — Best for Ultra-High Speed (if on budget)

For users with compatible USB 3.2 Gen 2×2 ports, Kingston offers the XS2000 in three capacities: 500GB for $99.99, 1TB for $159.99, and 2TB for $284.99. The 1TB model sits just above the $150 threshold, but Kingston's claimed 2,000MB/s read and write numbers are impressive and near the limit of what its USB 3.2 Gen 2×2 interface can handle (20Gbps). Just note that using a regular USB 3.2 Gen 1 (5Gbps) or Gen 2 port (10Gbps) will drastically limit the drive's capabilities.

What to Look for When Buying

Ensure the drive supports at least USB 3.2 Gen 2 for SSDs to get the 1,000MB/s speeds you're paying for. If you're a travel photographer, prioritize IP-rated water and dust resistance over a few extra gigabytes.

For most users, 1TB is the ideal capacity, holding roughly 250,000 photos or 250 hours of HD video, while content creators working with 4K video should consider 2TB since one hour of raw 4K footage uses about 240GB.

The Bottom Line

Finding a compact external SSD under $150 doesn't mean settling for slow or fragile storage. For most creators, photographers, and general users, there is no need to spend more unless you require 4TB+ capacities or Thunderbolt 4 speeds.

The best drive for you depends on your specific workflow—whether that's automatic backup software, rugged durability for field work, or raw speed for video editing. All the drives listed here deliver solid performance, compact form factors, and the reliability you need to keep your data safe whether you're traveling across town or across the globe.
