Best Memory Card for Sony RX100 VII
The Sony RX100 VII (DSC-RX100M7) is a 302 g 1.0-type compact with one SD slot. Sony’s own media line is UHS-I U3 for XAVC S 4K/HD at 100 Mbps — not a V90 UHS-II arm. 4K here is 30p/24p at 100 Mbps or 60 Mbps, about 12.5 MB/s at the high row. The card that matches that table is the SanDisk Extreme PRO SDXC UHS-I.

How We Picked
Three official facts. This is a UHS-I compact, not the a7C II UHS-II / V90 slot.
- Weigh the pocket body and the bit rate. Sony USA: 20.1 MP 1.0-type, 101.6 × 58.1 × 42.8 mm, 275 g body / 302 g with battery and card. Electronic shutter Hi about 20 fps; Single Burst 7 frames at 90/60/30 fps. XAVC S 4K is 30p/24p at 100 Mbps or 60 Mbps — there is no 4K 60p row. HD 120p is 100 Mbps. Compatible media: XAVC S 100 Mbps needs SDXC/SDHC UHS-I U3 or higher; 60/50 Mbps needs Class 10.
- Read Sony’s card table, not a V90 slogan. Help Guide Memory cards that can be used: stills any SD; 4K 100 Mbps / HD 100 Mbps = U3; 4K 60 Mbps and HFR = Class 10 / U1. 100 Mbps is 12.5 MB/s. U3’s 30 MB/s floor covers it. V90’s 90 MB/s floor is the a7C II S-I 600 Mbps conversation. August 2025’s version of this URL stacked Lexar 2000x, SF-G, ProGrade Cobalt, and Kingston React Plus — all UHS-II V90 — after correctly saying the bus is UHS-I.
- Capacity vs the battery, and USB 2.0 vs a reader. Sony recordable times (Sony card, proxy off): 4K 30p 100M is 1 h 15 min on 64 GB and 5 h 5 min on 256 GB. CIPA actual movie is about 40 min on the NP-BX1. 128 GB is the default; 32 GB is SDHC and splits XAVC S at 4 GB. The camera’s Multi/Micro USB is High-Speed USB 2.0 — SanDisk’s 200 MB/s QuickFlow rating is a reader number, not an in-camera dump.
Detailed Reviews
SanDisk Extreme PRO UHS-I View on Amazon View on B&H
| Bus / class | UHS-I, U3, V30 — SanDisk Extreme PRO UHS-I |
|---|---|
| 64–128 GB | Up to 200 MB/s read / 90 MB/s write |
| 256 GB–1 TB | Write up to 140 MB/s (SanDisk footnote) |
| Sony row | UHS-I U3 for XAVC S 100 Mbps |
| 128 GB vs 64 GB | Sony 4K 100M table: 64 GB ≈ 1 h 15 min |
Why it fits the RX100 VII. Sony printed UHS-I U3 for the 100 Mbps 4K/HD row. Extreme PRO is that class: V30 guarantees 30 MB/s sustained, more than double 12.5 MB/s. 20 fps e-shutter stills sit on the same U3 floor. 128 GB is the size that outlasts the NP-BX1’s ~40 min actual movie CIPA without living on SDHC’s 4 GB splits. The 200 MB/s read is for a UHS-I reader after the day; the camera’s USB 2.0 port will not deliver it. Skip the 32 GB SKU (100 MB/s read, SDHC).
Skip this if Rec Format never leaves 4K 60 Mbps / HFR. Class 10 / U1 is Sony’s row there — Extreme (not PRO) or Go Plus still U3 is extra, not required.
- U3 / V30 matches Sony’s 100 Mbps line
- 90 MB/s write rating is UHS-I, not a fake V90
- 128 GB covers a 40-minute CIPA movie day
- 200 MB/s needs a reader, not the camera’s USB 2.0
- 32 GB PRO SKU is the wrong capacity

Kingston Canvas Go Plus View on Amazon View on B&H
| Bus / class | Class 10, UHS-I, U3, V30 — SDG3 datasheet |
|---|---|
| 128 GB–1 TB | 170 MB/s read / 90 MB/s write |
| 64 GB | 170 / 70 MB/s |
| Not this card | Canvas React Plus (UHS-II V90) — a7C II Value |
Why it is Value. Same Video Speed Class as Extreme PRO. Kingston’s Go Plus is the UHS-I V30; React Plus is the UHS-II V90 we put on the a7C II page. August’s RX100 VII roundup used React Plus as pick five. Wrong bus. 128 GB Go Plus is 170/90; 1 TB exists if you never dump. Full 170 MB/s read needs Kingston’s MobileLite Plus reader — same reader caveat as SanDisk QuickFlow.
Skip this if the kit is already Extreme PRO. Do not buy a second U3 brand “for speed” on a UHS-I compact.
- U3 / V30 on Sony’s 100 Mbps row
- 1 TB SKU if cards never leave the camera
- Not the UHS-II React Plus
- 64 GB write rating drops to 70 MB/s
- 170 MB/s read is a reader number

SanDisk Extreme UHS-I View on Amazon View on B&H
| Bus / class | UHS-I U3 V30 — Extreme SD V30 datasheet |
|---|---|
| Sony 4K 100 Mbps | Still U3 — not Ultra U1 |
| 128 GB (datasheet) | Up to 230 MB/s read / 120 MB/s write |
Why it is Budget, not a Class 10. Extreme is SanDisk’s U3 V30 rung under PRO. In this camera the bus is UHS-I; peak MB/s on the box does not change 4K 100 Mbps. What changes is the street price. Ultra (U1 / V10 on many SKUs) fails Sony’s U3 line for 100 Mbps. HFR and 4K 60 Mbps are Class 10 — Ultra can do those rows, not the 100 Mbps row. Read the label: U3 and V30, SDXC, 64 GB or 128 GB.
Skip this if the listing is Extreme microSD plus an adapter. Sony allows microSD with an adapter; a full-size Extreme SD is the less fiddly pocket card.
- U3 / V30 without the PRO name
- Same Sony 100 Mbps row as Overall
- Easy to grab Ultra by mistake
- Peak 230 MB/s is still a reader number

If You Need Something Else
UHS-II V90 cards work. They record at UHS-I. They are the wrong first buy for a 302 g compact.
Sony SF-G Tough V90 View on Amazon View on B&H
| Bus | UHS-II V90, 300/299 MB/s — SF-G TOUGH specs |
|---|---|
| This site | Overall on the a7C II guide (S-I 4K 600 Mbps) |
August’s page listed SF-G, Lexar 2000x, ProGrade Cobalt, and Kingston React Plus as if faster in-camera. Sony’s RX100 VII line is UHS-I U3. SF-G is IP68 and V90 for S-I bodies. Keep it if it already lives in an a7C II; do not buy it to “unlock” 4K on this compact.
Skip this if the only camera in the bag is an RX100 VII. That is Extreme PRO UHS-I.

ProGrade Digital Cobalt V90 View on Amazon View on B&H
300/250 MB/s UHS-II V90. Layer 2 on the a7C II page. Same idea: compatible, not the default. 512 GB V90 is a dump-less cinema card this 40-minute CIPA movie battery will not fill.

Frequently Asked Questions
Why UHS-I U3 is Overall instead of V90
Sony: XAVC S 100 Mbps needs UHS-I U3 or higher. 4K is 30p/24p at 100 or 60 Mbps, not 4K 60p and not S-I 600 Mbps. V90 is the a7C II S-I row. U3’s 30 MB/s floor already covers 12.5 MB/s.
Whether a UHS-II card works in the RX100 VII
Yes. UHS-II cards are backward compatible and run at UHS-I in this slot. You pay for a second row of pins this body does not clock. Fine as a from another camera; wrong as the first purchase.
What capacity matches the battery
Sony’s 4K 30p 100M table: 64 GB ≈ 1 h 15 min, 256 GB ≈ 5 h 5 min (proxy off, Sony card). CIPA actual movie is about 40 min. 128 GB SDXC is the default. SDHC splits XAVC S at 4 GB.
Whether 4K 60p exists on this body
No. Sony’s NTSC 4K rows are 30p and 24p. 60p/120p on this camera is HD. Card speed does not add a 4K 60p mode.
Why 200 MB/s does not show up over the camera USB
Sony lists High-Speed USB (USB 2.0) on the Multi/Micro USB terminal. SanDisk QuickFlow 200 MB/s and Kingston 170 MB/s are reader figures. Pull the card for offload.
Final Verdict
For Sony RX100 VII, buy SanDisk Extreme PRO UHS-I in 128 GB. Take Kingston Canvas Go Plus when U3 is the spec and PRO is not the price. Take SanDisk Extreme UHS-I when the label still says U3 / V30. Leave SF-G and Cobalt V90 on the a7C II page. This slot is UHS-I.
