Which USB drive the R2 needs
Road Cam, the dashcam in the Rivian R2’s Gear Guard system, does not record until a drive is plugged in. The September 2026 R2 owner’s guide is specific about that drive: capacity, USB generation, write speed, file system, and a physical size. These drives line up with that list in different ways. The Samsung Type-C 256GB (datasheet) is the cheap plug-in stick. The SanDisk Extreme Fit 1TB (datasheet) is the same idea with more room. The Samsung T7 Shield 2TB (official page) is the SSD, at the guide’s 2 TB ceiling. The same drive also comes as the T7 Shield 1TB if the 2 TB price is more than you want to spend.
What the R2 USB ports are for
Each USB-C port in the R2 has a specific job.
The storage drive goes in the USB-C port in the center glove box. That is the port the Gear Guard setup steps name, for both Road Cam and for copying videos off the car. Plug the drive in directly. The guide rules out a hub or a splitter.

The other USB-C ports charge devices. The outlets section rates the center console at 60 W from one port, or 75 W with both ports in use, and the second-row ports at 15 W each. The charging chapter places those second-row ports at the back of the head restraints, and it says they are for a phone or a tablet. The same chapter says the glove box port is reserved and is not the one to charge from. Use it for the drive. Charge from the console or the second row.

Gear Guard splits its video across two places:
| What recorded | Where it is saved | Where you watch it |
|---|---|---|
| Road Cam clips (Save Clip, a long horn, or the SOS button) | External drive | Road Cam tab in the car, with the drive connected |
| Continuous Road Cam, while driving and while parked and occupied | External drive | On a computer, in Road Cam > Road Stream |
| Incidents, such as a collision or hard braking | Onboard drive | Incidents tab. You can copy a clip to the drive. |
| Motion Cam, and the alarm while Motion Cam is on | Onboard drive | Motion Cam tab. Deleted after 10 days unless you star it. |
Road Cam is the feature that needs the drive. With Road Cam on and a drive connected, the vehicle records the trip, and it also records while the vehicle is parked and occupied. Continuous files live only on that drive. When the drive gets full, the car deletes the oldest continuous recordings. Saved Road Cam clips stay until you remove them. If there is no room left for a new clip, the car will not record one.
Incidents and Motion Cam stay on the car’s own drive. Starring a Motion Cam clip keeps it past the 10-day delete. You can also copy those events onto the same USB drive you use for Road Cam. Video recording can reduce range over time.
What the storage drive has to be
The Road Cam setup in the owner’s guide asks for all of the following:
- 128 GB minimum, 2 TB maximum. A 64 GB stick is under the minimum. A 4 TB SSD is over the maximum.
- USB 3.x, and compatible with USB 2.0.
- An SSD is recommended for Road Cam. The copy-a-video steps list the same capacity, speed, and size rules and do not repeat the SSD line.
- 20 MB/s minimum random write.
- FAT32 or Ext4. A different file system gets a format prompt. Formatting erases the drive. The car can take a few minutes.
- No larger than 1.7 in (45 mm) by 1.2 in (30 mm).
The random-write line is the one a bargain stick fails. The number on a flash-drive box is almost always a sequential read. Rivian’s number is a random write, and the car checks the drive during setup. A package that says 400 MB/s can still be rejected.
None of the drives below publish a random-write figure. The two sticks publish a sequential read. The T7 Shield publishes sequential read and write, and it is an actual SSD, which is what the Road Cam section recommends.
The size line is just as strict. Both sticks are under 1.7 by 1.2 inches, so they can live in the port. The T7 Shield is 88 × 59 × 13 mm. That body does not meet the size line. It ships with a USB-C cable, and the drive then sits in the glove box instead of in the port recess. A hub is still out.
Quick Comparison
| Drive | Role | Capacity | Interface | Published speed | Size | Meets the 1.7 × 1.2 in limit | Warranty |
|---|---|---|---|---|---|---|---|
| Samsung Type-C (MUF-256DA) | Cheapest plug-in | 256 GB | USB 3.2 Gen 1 | Up to 400 MB/s read | 33.7 × 15.83 × 8.2 mm | Yes | 5 years |
| SanDisk Extreme Fit (SDCZ530-1T00) | More room, still plug-in | 1 TB | USB 3.2 Gen 1 | Up to 400 MB/s read; write speeds are lower | 18.50 × 15.70 × 13.60 mm | Yes | 5 years |

Cheapest: Samsung Type-C 256GB
Check the Samsung Type-C 256GB price on AmazonThe Samsung Type-C (model MUF-256DA) is a USB-C stick at 33.7 × 15.83 × 8.2 mm, about 3.4 g. That is inside the guide’s 1.7 by 1.2 inch limit, so it can plug straight into the glove box port and stay there.
Samsung rates the 128 GB through 512 GB versions at up to 400 MB/s read over USB 3.2 Gen 1, and the datasheet lists compatibility with USB 3.0 and USB 2.0. 256 GB clears the 128 GB minimum and stays well under the 2 TB cap. The datasheet does not publish a write speed. The warranty is 5 years. Samsung also lists resistance to shock, temperature, water, magnets, and X-rays. There is no IP rating on the sheet.
This is a flash drive, and the Road Cam section recommends an SSD. Buy it when you want the least expensive drive that meets the size, capacity, and USB rules, mostly to copy starred clips off the car. If setup fails the speed check, this is the pick that is most exposed to that.
The same family comes in 64 GB, which is under Rivian’s minimum, and in 128 GB and 512 GB. The 256 GB model is the one linked here.
Mid: SanDisk Extreme Fit 1TB
Check the SanDisk Extreme Fit 1TB price on AmazonThe SanDisk Extreme Fit (model SDCZ530-1T00) is the plug-in drive to buy when 256 GB is going to roll over too fast. It is 18.50 × 15.70 × 13.60 mm and about 3 g, so it also fits the size limit, and it is a single USB-C connector. The 1 TB capacity is legal under the 2 TB maximum and gives continuous Road Cam a lot more room before the oldest files are deleted.
SanDisk rates the 128 GB through 1 TB versions at up to 400 MB/s read on USB 3.2 Gen 1, and the datasheet says write speeds are lower. It does not give a write number, random or sequential. The warranty is 5 years.
It is still a flash drive. The extra capacity is the reason to step up from the Samsung stick. The SSD recommendation in the Road Cam section still points at the T7 Shield if recording all day is the actual job.
Skip the 64 GB Extreme Fit. It is under the 128 GB minimum. SanDisk also sells this shape in 128 GB, 256 GB, and 512 GB. The 1 TB model is the one that earns the step up.
Best: Samsung T7 Shield 2TB
Check the Samsung T7 Shield 2TB price on AmazonThe Samsung T7 Shield in 2 TB (model MU-PE2T0S) is the drive that matches the two lines that matter most for Road Cam: it is an SSD, and 2 TB is the largest capacity the guide allows. Samsung rates it at up to 1,050 MB/s read and 1,000 MB/s write on USB 3.2 Gen 2, with a USB-C port. Those are sequential figures, measured on a compatible host. They are not a published random-write number. They are also far above a thumb drive, which is why this is the pick when the car is going to write video for hours.
The body is 88 × 59 × 13 mm. That is larger than 1.7 by 1.2 inches, so it does not meet the size line as a drive plugged into the port. The box includes a USB-C to C cable and a USB-C to A cable. Use the USB-C cable, set the drive in the glove box, and do not put a hub or a splitter in between.
It is IP65 for dust and water, drop-rated to 3 m, and covered for 3 years. Samsung’s Dynamic Thermal Guard is there to hold performance during long transfers. Samsung lists an operating range of 0–60°C. A glove box in a closed car on a hot day can run past that.
Leave Samsung Magician’s password protection off. The car has to format the drive and write to it. Encryption for a drive you also use on a computer is a different job. The T7 Shield review goes further into the rugged spec, and the portable SSD comparison puts it next to faster 20 Gbps drives. For this car, a 20 Gbps drive does not change the job. The R2’s requirement is USB 3.x, an SSD, and a 2 TB ceiling. The Shield at 2 TB is the match. The 4 TB Shield is over that ceiling, so leave it.
Save money: the T7 Shield 1TB
Check the Samsung T7 Shield 1TB price on AmazonThe T7 Shield 1TB (model MU-PE1T0S) is the same SSD at half the capacity. Samsung lists the same 1,050 MB/s read and 1,000 MB/s write, the same 88 × 59 × 13 mm body, the same IP65 rating, and the same 3-year warranty. It still meets the SSD recommendation, and 1 TB is well inside the 128 GB to 2 TB range. The trade is only room: continuous Road Cam rolls over sooner on 1 TB than on 2 TB. Pick it over the SanDisk Extreme Fit 1TB when you want an SSD and do not mind the drive sitting in the glove box on its cable.
How to set the drive up
Park, open Settings, then Gear Guard, and choose Set Up Now. Accept the terms. Plug the drive into the USB-C port in the center glove box. If the car offers to format it, that erase is required. Give it a few minutes.
The R2 setup prompt before it formats the drive. Formatting erases everything on it.
To take the drive out, choose Eject in Gear Guard settings, or Eject from a tab in the Gear Guard app, and then unplug it. Continuous recordings are in Road Cam > Road Stream on a computer. The guide warns that the folders the car creates are how it recognizes the drive. If you delete files on a computer, empty that computer’s Trash or Recycle Bin before you unplug. A hidden trash folder on the drive still counts as full.
Road Cam Chime is on by default once a drive is connected. You can turn the chime off, and you can turn Road Cam off, under Gear Guard settings. Shipping mode disables Road Cam.
A saved clip runs for 2 minutes, and recording starts 15 seconds before you tap Save Clip. A horn held for more than a second, or the SOS button, also saves a clip. If you hit SOS by accident, cancel the call on the center display.
Rivian R2 USB drive FAQ
Does the Rivian R2 have a dashcam?
Yes. Road Cam is the R2’s dashcam, part of Gear Guard. It records only to an external USB-C drive in the glove box. Without a drive, Road Cam does not record. Incidents and Motion Cam, the R2’s version of a parked sentry mode, save to the car’s onboard drive.
Can I use a 4 TB drive in the R2?
No. The owner’s guide caps Road Cam storage at 2 TB. The 4 TB T7 Shield is over that limit. Buy the 2 TB.
Can I use a USB hub or splitter?
No. The guide says to plug the drive directly into the glove box USB-C port.
Why did the car reject my flash drive?
The R2 checks for at least 20 MB/s random write during setup. Speeds printed on a flash drive box are almost always sequential reads, so a stick can show a high number and still fail. An SSD such as the T7 Shield is the safer choice.
What format does the drive need?
FAT32 or Ext4. If the drive is in another format, the car offers to format it. Formatting erases everything on the drive.
Which port does the drive go in?
The USB-C port in the center glove box. The console and second-row ports are for charging.
Final Verdict
Buy the Samsung T7 Shield 2TB if Road Cam is going to stay on. It is the SSD the setup section recommends, at the largest capacity the guide allows. The T7 Shield 1TB is the same SSD for less money if you can live with half the room. Neither fits the port recess, so either one lives in the glove box on the cable that comes in the box.
Buy the SanDisk Extreme Fit 1TB if the drive has to plug straight into the port and you still want a serious amount of video on it. Buy the Samsung Type-C 256GB if you mainly need to copy a few starred clips and you want the cheapest stick that meets the size and capacity rules. Both sticks can fail the car’s write-speed check. The Shield is the one built for the recording.
