Better than I was expecting

Submitted on Saturday, December 08, 2018

Strengths of the product

Small size - fits in my Nintendo Switch, will work for many cell phones and other expandable storage devices Write speed is much better than expected (Class 10 UHS1 minimum write is 10MB/s). Usually you see 10-15MB/s speeds if they don't advertise higher. Price was reasonable.

Weaknesses of the product

Read speeds could be better compared to advertising on package, still not bad tho. Formatted space is 183 GB (196,832,395,264 bytes). I know its common for them to incorrectly list 1,000,000,000 bytes as 1GB but even by their numbers its only 196GB, we the consumer get screwed twice, once by rounding and again because 1024MB = 1GB not 1000MB. That missing ~20GB kinda hurts. The card I received was the red/grey color, not all black. Part number and ILC matched so maybe its just updated, or an old picture? Not a big deal but woulda been nice if the listing was accurate.

Additional Comments

Packaging advertised "up to 100MB/s", 667X (better than the 90MB/s, 660X advertised on the site, Sandisk probably updated the product with little or no warning.)

Benchmark: CrystalDiskMark 6.0.2 x64, 2GiB test, 5 runs. Kingston FCR-HS3 USB3 card reader
Read: 88.66MB/s Write: 61.99MB/s

Sandisk 200GB Ultra microSDXC Memory Card

Strengths of the product

The size allowed me to add a 158GB WMA9 6000+ Song Library to my phone

Weaknesses of the product

It did stop working after 6 months but I don't blame Sandisk as they are a quality company.
Every maker of memory products has a percentage of failures.

Additional Comments

Sandisk simply asked that I fill out a form with pictures to prove the MicroSD wasn't physically damaged and asked that I mail the SD to Ontario.
The whole process took less than 2 weeks and a brand new replacement is now on it's way back to me.
