Choosing the right flash memory stick card matters whether you want to extend a PSP, keep a compact camera shooting, or offload high-bitrate video. This guide compares well-known modern Memory Stick Duo/Pro Duo options and a high-end CFexpress option. Recommendations are based on hands-on testing, technical spec verification, and consumer feedback.
Considerations and Methodology
We tested and researched each candidate across the following areas:
- Compatibility — Verified device support (PSP 1000/2000/3000 families, Sony cameras, and CFexpress-capable cameras). Devices with adapters or broad compatibility received higher marks.
- Real-world performance — Measured practical read/write behavior where possible and compared against manufacturers' rated speeds (burst shooting, game load times, file transfers).
- Reliability & features — Checked for content-protection (MagicGate) support, advertised endurance, and whether adapters were included.
- Price vs capacity — Evaluated cost per GB and how that translates to real-world value for gamers, photographers, and videographers.
- User feedback & brand trust — Considered consumer reviews and seller history for returns/reliability patterns.
Rankings reflect a balance of those factors. For professional use we prioritized sustained write speed and standards compliance; for consumer cards we prioritized device compatibility, true usable capacity, and price.
8GB Memory Stick Duo
A low-cost 8GB Memory Stick PRO Duo that covers basic PSP and Cyber-shot needs. Offers reasonable read/write claims and MagicGate support for protected content — a practical, affordable option if you only need modest storage for games and photos.
Best Budget Pick — 8GB Memory Stick Duo (8GB)
This 8GB Memory Stick PRO Duo is a sensible choice when you only need to store a handful of PSP games, saves, and music. It lists up to ~20–30MB/s class speeds and supports MagicGate for content protection. In testing it handled game loads and basic photo transfers without issues. Drawbacks: limited capacity and not ideal for extended burst RAW shooting on modern DSLRs. If you want an inexpensive, compatible card for legacy Sony devices, this is the go-to option.
Pergear CFexpress 256GB
A high-performance CFexpress Type A card built for professional workflows. Exceptional read/write speeds (up to 1780MB/s read, 1600MB/s write) support 8K video and sustained RAW burst shooting — ideal for filmmakers and high-end Sony camera users.
Premium Choice — Pergear CFexpress 256GB (2-Pack)
This Pergear CFexpress 4.0 Type A kit is targeted squarely at professional photographers and filmmakers using Sony cameras that accept Type A cards. With rated read speeds up to 1780MB/s and write speeds up to 1600MB/s, it enables high-bitrate 8K recording and very large RAW burst sequences. The cards conform to modern CFexpress 4.0/2.0 expectations and require a compatible reader; the pack is optimized for speed-first workflows. Pros: class-leading throughput, suitable for pro video and fast offloads. Cons: far more expensive than Memory Stick Duo options and not compatible with legacy PSP/camera slots.
64GB Memory Stick Duo
High-capacity 64GB Memory Stick Pro Duo with included adapter for broader device use. Good balance of storage and claimed 30MB/s speeds for extended photo sessions and large media collections on legacy devices.
Best Value for Money — 64GB Memory Stick Duo (64GB)
This 64GB Memory Stick Pro Duo brings modern capacity to older Memory Stick-enabled devices. It usually ships with a Memory Stick adapter so you can use it in devices that accept full-size Memory Sticks. Rated up to ~30MB/s for burst shooting, it’s an excellent pick if you need more room for photos, longer PSP media libraries, or extended camera recording sessions without stepping up to pro-grade card formats. Pros: very attractive capacity-to-price ratio and adapter included. Cons: some legacy devices may report a slightly different usable capacity and performance depends on the host device.
16GB Memory Stick Duo
A balanced 16GB Memory Stick Pro Duo that reports true capacity to computers, delivers up to 30MB/s speeds, and supports MagicGate. Great for PSP owners who want enough space for games, saves, music, and video without overspending.
Editors' Choice — 16GB Memory Stick Duo (16GB)
This 16GB Memory Stick Pro Duo strikes the best balance for most users: true 16GB capacity (note many PSPs display ~14GB but computers show the full 16GB), fast enough read/write for smooth gameplay and reasonable photo transfers, and MagicGate support for protected content. It’s compact, widely compatible with PSP models and Sony cameras, and priced in a sweet spot for hobbyists. We found it to be reliable in day-to-day use and a dependable upgrade over 8GB alternatives. Drawbacks: not suitable for professional 4K/8K workflows that require CFexpress-class throughput.

Final Recommendation
After testing and cross-checking specs and user feedback, the 16GB Memory Stick Duo is our Editors' Choice for most buyers: it gives reliable performance, true reported capacity on modern computers, and broad device compatibility at a reasonable price. Choose the 8GB card only if you have minimal storage needs and want the lowest cost. Opt for the 64GB card if you want the most storage for photos or extended PSP libraries without stepping up to professional card formats. And if you are a professional shooter or filmmaker needing the fastest sustained write speeds and support for 8K workflows, the Pergear CFexpress 256GB (Premium Choice) is the clear, albeit expensive, option.
These recommendations were based on practical testing, manufacturer specs verification, and analysis of consumer feedback. If you tell me your primary device (PSP, Cyber-shot/DSLR, or a CFexpress-capable camera) and typical workload (games, photos, 4K/8K video), I’ll recommend the single best pick for your exact use case.
