Samsung MB-MC256GA

Advantages: fast, inexpensive, with a long warranty

Disadvantages: in the descriptions of all stores, the write / read speed is 100/90, but the packaging of two different copies from different stores of the 64-gigabyte version says 100/60. however, this is still enough to make adopted storage out of this card in android 6 and not suffer from brakes.

Comment: in fact, the write speed turned out to be higher than stated on the package. less reading, but it doesn't matter. * MB / s = 1,000,000 bytes / s [SATA / 600 = 600,000,000 bytes / s] * KB = 1000 bytes, KiB = 1024 bytes Sequential Read (Q = 32, T = 1): 96.494 MB / s Sequential Write (Q = 32, T = 1): 67.140 MB / s Random Read 4KiB (Q = 32, T = 1): 6.103 MB / s [1490.0 IOPS] Random Write 4KiB (Q = 32, T = 1): 2.707 MB / s [ 660.9 IOPS] Sequential Read (T = 1): 93.743 MB / s Sequential Write (T = 1): 66.061 MB / s Random Read 4KiB (Q = 1, T = 1): 5.134 MB / s [1253.4 IOPS] Random Write 4KiB (Q = 1, T = 1): 2.350 MB / s [573.7 IOPS] Test: 1024 MiB [E: 0.2% (0.1 / 59.6 GiB)] (x5) [Interval = 5 sec] Date: 2017/07 / 04 14:28:39 OS: Windows 7 Ultimate SP1 [6.1 Build 7601] (x64)

Advantages: WorkYUT (5 pieces). Exactly 128.

Disadvantages: If only the price. So we always want cheaper.

Comment: Only facts without emotion. They stand in Samsung J4, j4 +, Xiaomi Mi Max2 / 64, Mi Max2 / 128, and one in the Prestigio tablet for 2 years. Would stick in Honor 10 and Xiaomi Mi Note3, if there were slots. Swapped places. Before that, there was one in the Meise M5 Note. One of them worked in a (excellent) Canon Ixus 500 soap box, although she "had no right" to work there. She worked. Replaced with exactly the same, but 64GB. One of the phones will break down, - I'll insert it into the MacBook for additional. memory (in the card reader). I would not have written this review if I hadn't gotten a reminder to add information to the product rating (I just put 5). And also an abundance of negative opinions. One will be covered - I'll write right away. I advise you to purchase. I bought everything through Ya.Market in the stores mentioned in my reviews. I always keep receipts.

Advantages: I liked the map very much. Good speed, no slowdowns, no glitches.

Disadvantages: Until there was

Comment: Very satisfied. Good quality and not expensive price! Recommend!

Advantages: Quote from the manufacturer's website: EVO Plus cards are protected by 4 types of protection: they can withstand up to 72 hours in seawater (waterproof IEC 60529 and IPX7 housing), work in extreme temperatures (operating temperatures from -25 ° C to 85 ° C, non-working - from -40 ° C to 85 ° C), be in airport X-ray machines (up to 50 roentgens) or under the influence of electromagnetic waves (up to 15,000 gauss), equivalent to MRI [magnetic resonance imaging?]. High-quality SD-adapter included, speed does not decrease at all (met adapters cutting speed).

Disadvantages: The card is not intended for use in tasks related to intensive data recording (for example, video recorders or video surveillance systems). Contradictory characteristics are published on the official website - first the write speed is up to 90 MB / s, and immediately below - up to 60, on the blister, too, up to 60. Declared reading at a speed of 100 MB / s and writing up to 90 MB / s and not smells - in my specimen a maximum of 83 and 70, respectively. But 70 MB / s is still more than 60 indicated on the blister.At the same time, the SanDisk Extreme PRO SDHC / SDXC 64 GB UHS-I, UI class immediately after purchase 2.5 years ago gave me 50 MB CrystalDiskMark 5.0.2 x64 Sequential Read (T = 1): 94.369 MB / s Sequential Write (T = 1): 89.325 MB / s Test: 50 MiB [D: 98.2% (58.4 / 59.4 GiB)] (x5) [Interval = 5 sec] Date: 2015/11/13 0:19:42 OS: Windows 10 [10.0 Build 10240] (x64) And now (on the same hardware, see below), with the same program version 5.0.2) 50 MB sample Sequential Read (T = 1): 83.470 MB / s Sequential Write (T = 1): 54.735 MB / s and 1 GB sample Sequential Read (T = 1): 83.266 MB / s Sequential Write (T = 1): 79.069 MB / s OS: Windows 10 [10.0 Build 16299] ( x64) So understand here ... Either the SanDisk Extreme PRO card has degraded over the years in speed and reading and writing, or the card reader has a ceiling of 83 kopecks MB / s from somewhere, and therefore the SAMSUNG MB card has MC64GARU same read speed? For other users, reading at 96 MB / s is exceeding.
