How Not to Buy a SSD

Original Article ↗ Hacker News Discussion ↗

Counterfeit and misrepresented SSDs and hard drives are becoming common on major marketplaces such as Amazon, eBay, AliExpress, and regional platforms, with drives reporting fake capacities, spoofed SMART data, or being used and resold as new. Commenters describe how co-mingled warehouse inventory and lax policing by platforms make it hard to trust even “sold by Amazon” labels, and share strategies like buying directly from manufacturers, reputable specialists, or second‑hand enterprise drives instead. Various tools and practices are recommended to verify storage integrity—such as full-disk write tests and utilities like f3 or ValiDrive—before entrusting devices with important data.

Prevalence of Fake / Misrepresented SSDs and HDDs

  • Multiple anecdotes of clearly counterfeit or tampered drives from major marketplaces (Amazon, eBay, AliExpress, eMag), sometimes even labeled “new” and apparently sealed.
  • Common scam pattern on eBay: 4TB “brand-like” SSDs with lookalike Samsung/WD styling but no logo, containing ~100GB of flash and firmware that lies about capacity, then bricks once full.
  • Reports of HDDs with reset or forged SMART data, including drives showing >1 year powered-on time sold as “new.”

Marketplaces, Commingling, and Counterfeits

  • Strong criticism of Amazon’s commingled inventory: items marked “Ships from/Sold by Amazon” may actually be fulfilled from third-party stock, enabling counterfeits and returns fraud loops.
  • Some users say they’ve never seen a counterfeit from Amazon; others report multiple fake SSDs, SD cards, batteries, chargers, and even books.
  • Perception that Amazon has shifted from trusted store to chaotic marketplace with search spam, fake reviews, and lots of low-quality China-sourced goods.
  • Similar warnings about other marketplaces (AliExpress, eMag, etc.): deep discounts (70–80% off) are seen as a red flag.

How People Detect or Test Drives

  • Heuristics: suspiciously low weight, too-good-to-be-true price, missing major brand logo, odd packaging, or limited/odd SMART data.
  • Recommended tools:
    • Destructive full-disk write/read (e.g., f3 / f3fix) to detect capacity lies.
    • ValiDrive (Windows, non-destructive spot checks across the drive).
  • Note that some testing is destructive; people suggest doing it before putting drives into real use.

Buying Strategies and Trusted Channels

  • Many prefer:
    • Direct-from-vendor (WD, Seagate, etc.).
    • Reputable specialized retailers (B&H, Micro Center, local camera/PC shops).
  • Several users avoid buying any critical electronics, storage, or health/beauty items from Amazon or generic marketplaces.

Used Enterprise SSDs: Mixed Views

  • Some strongly favor second-hand enterprise SSDs (often SAS/U.2, with power-loss protection and high DWPD ratings), usually from eBay, Taobao, or forum marketplaces; claim excellent longevity.
  • Others argue pricing often overlaps with new consumer SSDs with warranties, making used enterprise less compelling unless you find real bargains.
  • Example strategies include mirrored arrays, ZFS, and optane for metadata to mitigate risk.

Drive Quality Notes

  • Kingston A400 line is called out as genuinely poor even when authentic (firmware issues, high failure rates).
  • Debate over old SLC vs newer MLC/TLC endurance, with conflicting anecdotal evidence about reliability vs cost/capacity.
