Best Memory Card for Canon EOS R8
The EOS R8 has one UHS-II SD slot. At 6 fps, Canon’s RAW burst is 1000+ frames on a UHS-II card and 85 on UHS-I — same body, wrong bus. 4K60 10-bit shares that door and is rated V60. SanDisk Extreme PRO UHS-II V90 matches the slot: 300 / 300 MB/s and a 90 MB/s floor. Check Extreme PRO UHS-II V90 on Amazon.

How We Picked
Three sourced facts: one UHS-II slot, an 85-versus-1000+ RAW buffer at 6 fps, and a V60 floor for 4K60 10-bit.
- Weigh the slot, then the 6 fps RAW row. Canon EOS R8 specifications and B&H 5803C002: a single SD/SDHC/SDXC slot, UHS-II. Electronic first-curtain at about 6 fps: RAW burst is 85 frames on a 32 GB UHS-I card and 1000 or more on a 32 GB UHS-II card. Electronic shutter at about 40 fps: 120 JPEG, 51 RAW on UHS-I, 56 RAW on UHS-II. Canon UK also lists RAW Burst at 30 fps with 0.5 s pre-record for about 158 frames, and recommends UHS-II for 4K and high-speed continuous shooting. One card. There is no overflow slot.
- Match V90 to the UHS-II body; match V60 to 4K60 10-bit. Canon’s compatible-cards table: 4K UHD 59.94 / 50 fps IPB Standard in 8-bit needs UHS Speed Class 3; the same size in 10-bit (Canon Log 3 / HDR PQ) needs Video Speed Class V60 or higher. SanDisk Extreme PRO UHS-II V90 publishes up to 300 MB/s read and write and a 90 MB/s V90 floor. That is the class you buy when 6 fps RAW 1000+ and 4K60 share one door.
- Size 128 GB for one slot. Canon’s 4K UHD 59.94p IPB Standard table is about 18 minutes on 32 GB, 1 hour 14 minutes on 128 GB, at about 230 Mbps. 32 GB is the burst-test size, not a travel size for 4K60 on a body with no second slot.

| SKU family | SDSDXDM — SanDisk Extreme PRO UHS-II V90 |

| Peak | Up to 300 MB/s read and 300 MB/s write |
| Capacity | Prefer 128 GB. 64 / 256 / 512 GB exist. |
| Body job | Canon: UHS-II slot · 6 fps RAW 1000+ · 40 fps 56 RAW · 4K60 10-bit V60 |
Why it fits the R8. The slot is UHS-II. The number that decides this purchase is the 6 fps RAW row: 1000+ frames on UHS-II, 85 on UHS-I. 40 fps RAW is 56 frames on the fast card. 4K60 10-bit is V60 on Canon’s movie table, so V90’s 90 MB/s floor covers that codec and the burst on the same door.
Buy 128 GB when 4K60 and stills share the card — Canon’s time table is about 1 hour 14 minutes of 4K60 IPB Standard at that size. Skip this card only when the day never uses 6 fps RAW or 40 fps and 4K60 10-bit is the ceiling; that job is V60.

Lexar Professional 2000x SDXC UHS-II GOLD View on Amazon View on B&H
| SKU family | Professional 2000x GOLD — Lexar |
|---|---|
| Class | UHS-II · U3 · V90 |
| Peak | Up to 300 MB/s read · up to 260 MB/s write |
| Capacities | Lexar: 64 / 128 / 256 / 512 GB |
Why it is Value. Lexar’s 2000x GOLD sheet is also V90 UHS-II. You stay on the class that covers 6 fps 1000+ RAW and 4K60 10-bit. The write peak is 260 MB/s instead of 300. Full speed still wants a UHS-II reader. 128 GB is still the one-slot size.
Skip it when the brief is only V60 video and stills — that is 1800x GOLD. Pair it with a flash for this body on a stills day; the slot does not change.

Lexar Professional 1800x SDXC UHS-II GOLD View on Amazon View on B&H
| SKU family | Professional 1800x GOLD — Lexar |
|---|---|
| Class | UHS-II · U3 · V60 |
| Peak (64–128 GB) | Up to 280 MB/s read · up to 210 MB/s write |
| Peak (256 GB–1 TB) | 280 / 205 MB/s |
Why it is Budget. V60 is the class Canon lists for 4K UHD 59.94p IPB Standard in 10-bit. 8-bit 4K60 is U3, which V60 includes. The reason this body still wants V90 as the default is the 6 fps RAW buffer on one UHS-II slot — 1000+ versus 85 — not the movie row.
Take 1800x GOLD when the day is 4K30 / 4K60 10-bit and stills. Step to V90 when 6 fps RAW or 40 fps shares the card. An ND filter for this body does not change the bus.

If You Need Something Else
A UHS-I V30 card still records. Canon’s own burst table is why it is not the R8 card: 85 RAW at 6 fps instead of 1000+.

Frequently Asked Questions
Why V90 UHS-II on this body
Canon lists a single UHS-II slot. At 6 fps, RAW is 1000+ frames on UHS-II and 85 on UHS-I. 4K60 10-bit is V60. V90 is the UHS-II class with a 90 MB/s floor when burst and 4K60 share that door.
Whether 4K60 10-bit requires V90
Canon’s movie table asks Video Speed Class V60 or higher for 4K UHD 59.94 / 50 fps IPB Standard in 10-bit (Canon Log 3 / HDR PQ). 8-bit 4K60 is UHS Speed Class 3. V90 is the burst card, not the movie minimum.
Why 128 GB instead of 32 GB
One slot. Canon’s 4K60 IPB Standard time table is about 18 minutes on 32 GB and 1 hour 14 minutes on 128 GB, at about 230 Mbps. 32 GB is the size Canon used for burst tests, not a travel card for 4K60.
Whether UHS-I Extreme PRO is enough
That SKU is a UHS-I V30 card. This camera’s slot is UHS-II. The 6 fps RAW buffer is 85 frames on Canon’s UHS-I test card. Save UHS-I Extreme PRO for a UHS-I body.
What 40 fps RAW asks of the card
Canon: about 56 RAW or 120 JPEG at 40 fps on a UHS-II card, 51 RAW on UHS-I. RAW Burst at 30 fps with 0.5 s pre-record is about 158 frames. The larger gap is still 6 fps RAW: 85 versus 1000+.
Final Verdict
For the EOS R8, buy SanDisk Extreme PRO UHS-II V90 in 128 GB. Take Lexar 2000x GOLD when the class is still V90. Take 1800x GOLD V60 when the day is not 6 fps RAW. Leave UHS-I cards in UHS-I cameras — 85 RAW at 6 fps is the published cost of that bus.
