Seagate 2TB HDD vs Samsung 990 Pro SSD: Which Wins?

Seagate Portable 2TB External HDD (USB 3.0, with 1-Year Rescue Service)

1. Reliability & Data Security

• Many users praise the “ample storage capacity, ease of use, and reliable functionality” along with Seagate’s included 1‑year Rescue Data Recovery service.

• However, anecdotal reports caution potential issues: one user experienced multiple failures with Seagate One Touch 2TB drives, requiring replacements.. Others report poor write performance on newer 'shingled' models .

• Verdict: Offers backup assurance via Rescue service, but hardware reliability may vary by batch.

2. Speed & Performance

• As a 2.5" spinning-disk drive (5400 RPM), it’s modest in speed—TechRadar’s similar Seagate model clocked ~140 MB/s reads and ~137 MB/s writes

• The SATA-based HDD performs reliably for large-file dumps but lags behind SSDs for random or frequent file access.

3. Capacity & Value

• Boasts a generous 2 TB capacity at an affordable price (~US$60), with high user satisfaction for price-per-terabyte 

• Verdict: Excellent value for bulk storage and backup, ideal for those needing lots of space without high cost.

Samsung 990 Pro 1TB PCIe 4 NVMe SSD (M.2, up to 7,450 MB/s)

1. Reliability & Data Security

• Samsung’s Magician Software provides robust management tools—health monitoring, firmware updates, performance tracking—for long-term reliability

• Widely trusted, though some users criticize its high price relative to value, saying the benefits may not justify the cost for average use 

2. Speed & Performance

• Delivers blazing sequential speeds—up to 7,450 MB/s reads and ~6,900 MB/s writes with exceptional random I/O improvements (~55 % over the 980 Pro) 

• Recognized as “one of the best SSDs for gaming,” with unmatched Gen 4 performance, though its 4K single-queue random access isn’t groundbreaking 

3. Capacity & Value

• Smaller at 1 TB—you get less capacity than the Seagate. Pricing has recently become more attractive due to newer SSD launches, improving its value proposition 

• Verdict: Premium performance at a still-competitive yet higher price, ideal for gamers and professionals demanding speed.
