The Sony Cyber-shot DSC-HX90V accepts SD, SDHC and SDXC cards (including UHS-I SDXC), as well as Memory Stick formats. SDXC is the sensible format to buy now. Sony’s guide says its SD cards up to 64GB were tested and proven, and XAVC S HD requires an SDXC card of at least 64GB with Class 10 or UHS Speed Class 1 performance. That makes a full-size 64GB SDXC card the conservative sweet spot: it enables the camera’s XAVC S HD mode without relying on untested larger capacities or a microSD adapter.

The picks, in detail
SanDisk 64GB Extreme UHS-I SDXC V30
A 64GB full-size Extreme V30 is the direct, conservative pick for HX90V XAVC S HD: it is SDXC, exceeds Sony’s Class 10/U1 minimum, and stays within the capacity Sony tested.
- 64GB SDXC
- UHS-I, U3 and V30
- full-size SD card
- Meets the 64GB SDXC condition for XAVC S HD
- V30 offers more write headroom than required
- 64GB fills sooner than modern 128GB cards, but that is deliberate here
Samsung PRO Plus 64GB Full Size SDXC
Samsung’s 64GB full-size PRO Plus is an SDXC/U3/V30 alternative for the HX90V owner who wants a current mainstream card without switching to an adapter-based microSD setup.
- 64GB full-size SDXC
- UHS-I, U3 and V30
- rated for 4K UHD and Full HD
- Correct full-size SD format
- Capacity falls within Sony’s tested-card guidance
- Be careful not to order the separate microSD PRO Plus listing
Kingston 64GB Canvas Go! Plus UHS-I SDXC
The 64GB Canvas Go! Plus is a current full-size U3/V30 SDXC card and a practical dedicated HX90V card for travel stills plus XAVC S HD clips.
- 64GB SDXC
- UHS-I, U3 and V30
- 30 MB/s minimum write rating
- Exceeds Sony’s stated XAVC S minimum
- Avoids the adapter the camera requires for microSD
- The HX90V cannot benefit fully from its modern peak transfer claims
Lexar 64GB Professional SILVER PLUS UHS-I SDXC
Lexar’s 64GB SILVER PLUS is a full-size V30 card with a quoted 100 MB/s maximum write speed, a capable option for the HX90V’s compact-camera burst and video work.
- 64GB SDXC
- UHS-I, U3 and V30
- 205 MB/s read and 100 MB/s write ratings
- Current product line sold by photo retailers
- 64GB meets the XAVC S capacity rule
- Priced above entry-level 64GB cards
PNY 64GB Elite-X UHS-I SDXC V30
PNY’s 64GB Elite-X offers an honest lower-cost full-size SDXC route to the HX90V’s XAVC S requirement, provided the specific listing carries the U3/V30 markings.
- 64GB SDXC
- UHS-I, U3 and V30
- Class 10 card
- 64GB SDXC is the documented capacity target
- Usually competitively priced
- Do not confuse it with PNY’s V10 Elite cards
Transcend 64GB 300S UHS-I SDXC V30
The 64GB Transcend 300S is a full-size V30 SDXC card that fits the HX90V’s tested-capacity guidance and makes a sensible separate-card backup for a small travel camera.
- 64GB SDXC
- UHS-I, U3 and V30
- full-size SD format
- V30 specification exceeds Class 10/U1
- Simple, direct fit with no adapter
- Not a high-end workflow card
Delkin Devices 64GB Advantage UHS-I SDXC V30
Delkin’s 64GB Advantage gives the HX90V a specialist photo-card option that remains within Sony’s tested 64GB size while carrying a modern V30 video class.
- 64GB SDXC
- UHS-I, U3 and V30
- full-size card
- Camera-media specialist brand
- Correct capacity for XAVC S HD
- Can cost more than general-retail cards of the same size
ProMaster 64GB 633x Advanced UHS-I SDXC V30
ProMaster’s 64GB 633x Advanced is explicitly specified as UHS-I U3/V30 with a 90 MB/s write rating, making it an unusually clear-spec alternative for the HX90V.
- 64GB SDXC
- UHS-I, U3 and V30
- 95 MB/s read and 90 MB/s write ratings
- Published U3/V30 specification
- 64GB capacity matches Sony’s tested guidance
- Not stocked as widely as the biggest memory-card brands
Sony TOUGH 64GB SF-M UHS-II SDXC V60
Sony’s own 64GB TOUGH SF-M is a robust, higher-spec SDXC option for an HX90V owner who values the durable card construction; it will operate at the camera’s compatible speed rather than delivering UHS-II performance.
- 64GB SDXC
- UHS-II, U3 and V60
- TOUGH durable card line
- Same-brand media option
- 64GB stays inside the tested capacity guidance
- V60/UHS-II is more card than this compact camera needs
Buying tips
- For XAVC S HD, choose a 64GB-or-larger SDXC card; a speedy 32GB SDHC card does not meet Sony’s stated capacity condition.
- Use full-size SD cards where possible. The HX90V can use microSD only through the appropriate adapter, adding another contact point and a small item to lose.
- Treat 64GB as the conservative maximum for this camera because Sony documents testing to that capacity; format the card in-camera before important shooting.
