Best Samsung Memory Cards

TL;DR: The Samsung EVO Select 256 GB microSDXC delivers 256 GB of storage, up to 160 MB/s read speed and rugged six‑proof protection, but its $74.49 price puts it at the premium end of the lineup.

This card’s standout spec is its 256 GB capacity paired with a manufacturer‑claimed read speed of up to 160 MB/s and write speed up to 90 MB/s, making 4K UHD video capture and large app libraries feel effortless. It also offers six‑proof durability – IPX7 waterproof for 72 hours in seawater, magnetic resistance up to 15,000 gauss, X‑ray resistance up to 100 mGy, and 10,000 mating cycles.

Compared with the other six cards in the roundup, the EVO Select 256 GB is heavier than the EVO Plus 256 GB (its weight is about 0.03 lb versus roughly 0.00057 lb for the Plus) while sharing the same 11 mm × 15 mm × 1 mm footprint. It matches the EVO Plus on read speed (both list up to 160 MB/s) but carries a higher price tag than the lower‑capacity options and the 128 GB PRO Endurance model.

Users consistently highlight the card’s reliable speed for 4K video and the peace of mind from its rugged design, especially the included full‑size SD adapter that simplifies transfers. A common complaint is that speeds can dip on devices that don’t support UHS‑I, leading to lower real‑world performance than the advertised 160 MB/s.

Technical details include a UHS‑I interface, Class 10/U3/V30/A2 speed classes, and an operating temperature range of –25 °C to 85 °C. The card supports 12 MP photo resolution and 4K UHD (3840×2160) video at 30 fps, and Samsung backs the card with a 1‑year warranty.

It’s also a touch lighter than the PRO Ultimate and EVO Plus 256 GB cards, each listed at about 0.00057 pounds.

Users consistently praise the card’s ability to hold extensive 4K video libraries and its quick file transfers, thanks to the “up to 100 MB/s” read performance.

What really stands out is the 200 MB/s sequential read speed paired with a sustained 130 MB/s write speed. Those numbers sit at the top of the UHS‑I class and let you offload 4K footage or launch apps without a noticeable lag. The card also carries U3, V30, Class 10 and A2 speed class ratings, so it’s ready for high‑bit‑rate video and demanding mobile games.

Compared with the six other Samsung cards in this roundup, the PRO Ultimate reads faster than the EVO Plus 256 GB and 128 GB (both listed up to 160 MB/s) and outpaces the PRO Endurance, EVO Select 256 GB and EVO Select 512 GB (max 100 MB/s).

TL;DR: The Samsung EVO Plus 128 GB microSDXC delivers up to 160 MB/s read speed, 4‑Proof durability and a full‑size SD adapter for $24.95, making it a solid budget choice for 4K video and everyday storage.

The standout spec is the read speed of up to 160 MB/s, which professional reviewers cite as “consistent across tested UHS‑I devices” and users love for quick 4K video off‑loading. Coupled with a minimum write speed of 30 MB/s, the card balances fast reads with reliable writes for most mobile workflows. Its rugged design—survives a 5 m drop, resists 15,000 gauss magnetic fields and endures 72 hours seawater immersion—means you can trust it in harsh conditions.

Compared with the six other Samsung cards in this roundup, the EVO Plus sits in the middle of the price band and offers more write speed than the PRO Endurance 128 GB’s “up to 40 MB/s” limit, while still lagging behind the EVO Plus 256 GB’s “up to 90 MB/s” write claim. Its read speed matches the EVO Plus 256 GB and the EVO Select 256 GB, but it weighs more than the latter’s listed 0.0005732018812 lb. The PRO Ultimate 128 GB and PRO Plus 128 GB list fewer durability specs, so the EVO Plus’s four‑proof rating feels more comprehensive.

User sentiment repeatedly praises the card’s “smooth 4K video capture” and “fast file transfers,” echoing the expert note that the A2 class rating boosts app performance on compatible phones. A common complaint is the noticeable gap between read and write speeds, especially on devices that don’t fully support UHS‑I. Still, most reviewers agree the trade‑off is acceptable for the price and capacity.

Best for: Budget‑conscious buyers seeking a reliable entry‑level option

Avoid if: You need the highest possible write speeds for intensive video editing or rely on UHS‑II performance

TL;DR: The Samsung EVO Plus 256 GB microSDXC delivers 256 GB of storage, up to 160 MB/s reads and 90 MB/s writes in a tiny 1 mm‑thick card for $32.50.

What really stands out is the 256 GB capacity paired with a read speed of up to 160 MB/s and a guaranteed minimum write speed of 30 MB/s (peak 90 MB/s). Those numbers let you stash thousands of photos or several hours of 4K video without worrying about space, and the U3/V30/A2 class keeps the card fast enough for most smartphones, action cameras and drones.

Compared with the six other cards in this roundup, the EVO Plus sits on the lighter side. At 0.25 g it’s lighter than the EVO Select 256 GB (13.6 g) and the EVO Plus 128 GB (20 g), while matching the featherweight of the PRO Ultimate, which shares the same 0.00057‑pound rating. It also costs less than the premium‑positioned EVO Select 256 GB, making it a solid budget‑friendly choice without sacrificing the core performance specs.

Users consistently praise the massive 256 GB capacity and the included full‑size SD adapter for hassle‑free transfers to laptops or cameras. Professional reviewers note the U3/V30/A2 rating as reliable for 4K video capture, though they also point out that peak read speeds can fall short of the 160 MB/s figure on devices that don’t support UHS‑I. A common complaint is the lack of bundled management software, which can be a minor inconvenience for less‑tech‑savvy owners.

Samsung built the card for durability; it rates for 10,000 mating cycles, operates between –25 °C and 85 °C, and runs on a 2.7‑3.6 V supply. Samsung’s FCC, CE, VCCI and RCM certifications add an extra layer of confidence for everyday use.

The standout spec is the 70,080‑hour endurance rating, which Samsung translates to roughly eight years of nonstop Full HD recording. Coupled with a 128 GB capacity, the card also delivers up to 100 MB/s read speed and up to 40 MB/s write speed, meeting the U3 and V30 speed class requirements.

Compared with the other six cards in this roundup, the PRO Endurance is among the lightest options at 0.000551155655 pounds—lighter than the Samsung PRO Ultimate 128 GB and matching the weight of the EVO Select 512 GB. Its 128 GB capacity is smaller than the 256 GB and 512 GB peers, and it sits at a premium price point relative to those larger‑capacity models.

Professional reviewers note the enterprise‑grade NAND flash and durability‑focused design, while users appreciate the 10,000 insertion/removal cycle rating and the CE, FCC, RCM, VCCI certifications. The 5‑year manufacturer warranty and an operating temperature range of –25 °C to 85 °C add confidence for rugged, always‑on setups like dash cams or body‑worn cameras.

Best for: Security and surveillance systems, dash cameras, and body‑worn cameras that need nonstop recording reliability.

TL;DR: At $23.99 the Samsung PRO Plus 128GB scores a solid 4.7 / 5 from over 12 k reviewers, praised for fast 4K performance and rugged durability.

Samsung’s PRO Plus microSDXC lands at the bottom of our seven‑product roundup with a score of 45 / 100, earning the #7 rank. It’s priced at $23.99 and carries a 4.7‑star rating based on 12,612 consumer reviews, putting it on par with the other Samsung cards in terms of overall satisfaction.

Buyers consistently highlight the card’s speed, noting that it handles 4K video capture and rapid file transfers without hiccups. The durability claims also resonate – users appreciate the waterproof and drop‑resistant construction, as well as the 10‑year limited warranty that adds peace of mind. On the flip side, some reviewers mention slower transfers on older devices that lack the latest UHS‑I interface, and the warranty does not cover high‑write scenarios like dashcams or continuous surveillance.

In the broader Samsung lineup, this model offers a competitive price point while matching the brand’s reputation for reliability. It sits below the higher‑priced EVO Select and PRO Ultimate options, making it a sensible choice if you want Samsung quality without the premium price tag.
