Lenovo became a well-known computer manufacturer — at least, in my mind — after they acquired IBM’s PC manufacturing business in 2005, which included IBM’s ThinkPad line of laptops. Being that they are a major brand name, they are a frequent target for counterfeiters — AliExpress searches reveal a wide array of fake flash bearing the Lenovo brand name.
This card, however, doesn’t seem to bear any of the hallmarks of fake flash: branding is present and on-point, color schemes match the brand’s color scheme, the card’s capacity is printed on the packaging, there are disclaimers printed on the package about the definitions of a kilobyte/megabyte/gigabyte, and there is contact information printed on the package. While none of these factors individually would be enough to convince me that a product is genuine, the combination of all of them tells me that this product is most likely genuine. And on top of all that…the card is not fake flash.
These cards met all the criteria that I set out for determining what’s considered a name-brand card — which means that I’ll lump them in with the name-brand cards in my results.
On the performance testing front: I purchased three cards, but I’ve only tested two of them as of the time of this writing. However, all of the measurements I took from those two have been above average, with sequential write speeds being this card’s strong suit — one scored in the 80th percentile, while the other scored in the 92nd percentile.
These cards bear the Class 10, U3, V30, and A1 marks — and all performance measurements were good enough to qualify it for all of these marks. (Well done, Lenovo!)
On the endurance testing front:
- Sample #1 has survived 5,170 read/write cycles in total so far.
- Sample #2 has survived 5,324 read/write cycles in total so far and has not yet experienced any errors.
- Sample #3 has survived 4,013 read/write cycles in total so far and has not yet experienced any errors.
Overall? So far, this seems to be a good card in terms of performance — but I think I need to wait to see how they do on endurance tests before I make any judgment calls on them.
