5 Fastest and Most Reliable Memory Cards of 2021

A fast 64 GB memory card, but a 128 GB version is also available. Executed in the popular microSD format and comes immediately complete with a USB-standard card reader. Another important detail is the manufacturer's extended service life of three years. This means that the card is very reliable and will survive a huge number of data rewriting cycles, which is important when used in cameras, video recorders and other equipment that requires constant updating of information. In customer reviews, it is noted that this model is one of the best among high-speed Micro SD memory cards, but many consider its price to be clearly overpriced even against the background of an extended delivery set. Another unpleasant moment is the strong heating of the standard card reader during prolonged use.

This memory card does not belong to the popular microSD format, but is made in the Compact Flash form factor. This standard is considered obsolete, but it continues to be actively used in a large number of cameras and other equipment that requires reliable operation of the storage medium. In terms of speed, Compact Flash cards are somewhat inferior to Micro SD, but still remain fast enough to be included in our rating. It is worth adding that the Compact Flash standard is very hardy, so the manufacturer measured the TS32GCF1000 card with a 5-year warranty right away, but it is available only in authorized stores. In user reviews, the increased reliability of the model and its high speed of operation are noted, although there are also rare complaints about failure after six months or a year of operation, as well as instability of the rewriting speed on some devices.

Inexpensive, but fast and, most importantly, reliable memory card that supports the UHS-II interface. This model complies with the V90 class according to the VSC standard, i.e. provides high-speed video recording in the highest resolutions at speeds up to 90 MB / s. All this allows us to confidently consider Transcend TS32GSDC700S one of the best in the segment of fast memory cards. Agree with this statement and users who share their impressions in the reviews. The card is called the most budget among high-speed models, but at the same time reliable enough for regular use, for example, in professional cameras. As for the shortcomings, they are not significant. First, the manufacturer saves on packaging, supplying the card only in a blister without a case. Secondly, on some card readers, the data exchange speed is noticeably poorer than the declared one.

Kingston's popular Canvas React Plus memory card series includes 128GB, 256GB, and 64GB options. Our top includes the latest modification, which offers the most adequate ratio of price, reliability and speed. This model is quite fast both for writing and reading data, corresponds to Class 10 and V90 classes, plus it is made in microSDXC format and supports UHS-II interface. A nice bonus is a small card reader included in the package. According to the reviews, this high-speed memory card is the best choice for recording video in 4K or 8K resolution. It is perfectly compatible with all modern cameras and camcorders, confidently delivers a write / read speed close to the declared one and is not afraid of intensive use. The main drawback of the model is typical for most of these devices - the regular card reader from the delivery set often overheats, which can cause premature failure of the card itself.

High-speed and reliable memory card from the American company SanDisk. The Extreme PRO series is designed for those who actively use media in cameras and other gadgets, while certainly needing the highest data transfer speed. The card format is SDHC, so you can’t insert it into Micro SD slots, but this is expected, because you have to pay something for reliability and increased speed. By the way, about the board, in customer reviews, it is the cost of this model that is considered the main drawback, if we evaluate it in terms of gigabytes / rubles. On the other hand, the SanDisk Extreme PRO SDHC 32 GB memory card fulfills its price completely, being perhaps the fastest in its price range and at the same time not losing reliability.
