The buying question

Do your existing cards need extra slots, or do your computers need different USB plugs?

30333 adds card-family slots but connects through USB-A. 50706 provides two host-plug choices with SD/microSD slots.

Quick verdict

When to skip: You require both native USB-C and direct Memory Stick insertion.
When the recommendation changes
  • Your next computer has only USB-C.
  • Your existing collection includes a listed Memory Stick variant.
  • You need both native USB-C and direct Memory Stick insertion.

The differences that matter

Native Host Connection

UGREEN 30333 (Black)

USB-A host plug.[1]

UGREEN 50706 (Deep Gray)

USB-A and USB-C host plugs.[3]

What this changes: For supported SD/microSD cards, 50706 avoids a separate host adapter when moving between compatible USB-A and USB-C computers. With a USB-A computer, let your cards decide.[1, 3]

The better fit depends on your priorities

Supported Media Fit

UGREEN 30333 (Black)

SD and microSD slots plus CF and MS slots; the listed Memory Stick variants include MS PRO, MS PRO-HG and MS XC DUO.[2]

UGREEN 50706 (Deep Gray)

Two card slots: SD and microSD, including SDHC/SDXC and microSDHC/microSDXC. There is no native MS or CF slot.[3]

What this changes: On a compatible USB-A computer, a listed Memory Stick card favors 30333. For an SD/microSD-only collection, extra card-family slots do not solve a necessary compatibility problem.[2, 3]

Only supported SD/microSD cards and a USB-A computer

No clear winner

Both cover the connection types needed. Choose between current offers rather than paying for unused slots or plugs.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Any premium should pay for a connection your actual setup needs.

There is insufficient verified price history for a buy-now or wait recommendation.

Limitations

  • No hands-on transfer, heat or reliability testing was performed. USB interface ratings are not guaranteed card-copy speeds.
  • Check your exact card and computer compatibility before ordering. The manufacturer’s 30333 capacity statements conflict, so no capacity ceiling is endorsed here.
  • Compact Flash is listed for 30333, but this recommendation uses the explicitly named Memory Stick variants. Verify your exact CF subtype separately; this page does not establish other CF-family compatibility.
  • 50706 mobile use requires OTG; Samsung phones need FAT32/exFAT rather than NTFS, and the listed phone-case limit is 1 mm. These conditions do not establish universal phone or operating-system support.

Questions shoppers ask

Should I replace a reader that already fits my cards and computer?

These specifications establish no faster-copy or reliability reason to replace it. A change is useful when your required host connection or media type no longer fits.

What should I check before using 50706 with a phone?

Check OTG support, the stated card-format requirements and case clearance. Use the microSD slot’s locking/eject mechanism and retain the protective plug caps.

What if I need Memory Stick and USB-C together?

Look for a reader documenting both, or separately verify an adapter setup. Neither selected reader supplies that combination directly.
