1 Introduction
The TF (MicroSD) card may be the best performance within 300 yuan:
Samsung (SAMSUNG) 128GB UHS-1 Class10 TF (Micro SD) memory card (reading speed 100Mb/s) upgraded version 299 yuan Jingdong direct link Recently just replaced the phone, the new phone supports TF card to expand the storage capacity, so I always wanted to enter a SDXC (≥ 64G) TF card
Helplessly, the price of storage equipment has skyrocketed for some time. Still, some people are reconciled.
Buy expensive reluctant to buy cheap sure write speed not
Until the day before the mother saw the memory card, nominal write speed 90
This has reached the speed of sandisk's extreme pro(tf)
And the highest sandisk also 64G, even if the discount has to be around 229
The other 300-bit 128G card...
Just after 0:00 on the 27th, it's worth 289 again. There are just 199-16 coupons.
I wouldn’t wait until I locked the order first. I saw it at 9:00 in the morning and it really rose back to 299.
At noon on the 28th finally got the hand
2. Unpacking:
This packaging is really more and more simple
It's okay for Nima to get me a bubble wrap.
Forget it, Dog East Express is OK, there is no problem with appearance
back
Nominal reading speed 100, writing speed 90
Out of the box... Oh no... Anyway, open the package
Hundreds of things don't even come with a card holder
NEXT, Macro:
Positive body
back
With the appearance of the active duty card on hand
Sort the same as above, respectively MIP, MIK, MIC
After patting and remembering, I still have a 2G Kingston bought in 2009. I can still serve normally for so many years. The quality is really leveraged.
The main camera used on the camera is the Toshiba EXCERIA series of cards
Sort the same as above, SD card is MIJ, MIJ, MIT
Next, let's list all the links mentioned above worthy of the card.
SanDisk Extreme High-speed Mobile MicroSDHC UHS-I Memory Card TF Card 16GB Class10 Read Speed ​​80MB/s39.9 Yuan Jingdong Direct Link This card of SanDisk was probably bought in 2012 and it was broken once. The official tossed it for more than one month and gave a free replacement card.
For now, the cost is not high, a small capacity, there is also a speed is not awkwardly
Measured on the hand of this 16G card reading speed of 37 or so, the writing speed of 13 or so (the old card performance may decline, for reference only)
Samsung (SAMSUNG) 32GB UHS-1 Class10 TF (Micro SD) memory card (reading speed 48Mb/s) upgrade version 89.9 yuan Jingdong direct link Just took a look at the order record. I bought this product in January of 1995, 78 pieces.
Now, Dog East sells 89.9 in terms of performance.
Measured on the hand of this 32G card reading speed of 45 or so, write speed of 22 or so (the old card performance may decline, for reference only)
The general use of this speed is almost enough, I was on a domestic sports camera recorded 2K video, use no problem
Kingston 16GB 80MB/s SD Class10 UHS-I High Speed ​​Memory Card 56.9 yuan Jingdong direct link This product is completely free gift, I must not buy it if I want to buy it myself.
The speed is so slow that it only hopes that it will keep Kingston's consistent resistance and be honest with the spare tire.
Measured on the hand of this 16G card reading speed of 80 or so, the writing speed of 13 or so (new card, the individual may have differences, for reference only)
Toshiba (TOSHIBA) EXCERIA Extremely Transient U3 SDHC-16G Read 95M Write 60M Support 4K HD 79.9 yuan Jingdong direct link 32G seems to be off the shelf...
Card is a good card, especially when there is a discount, but it is not a good price
I can only say that I got 3 cards at the following price
So it's good to pay more attention to Zhang Aunt
Since the best card on hand is this Toshiba SD card with a nominal reading speed of 95 and a writing speed of 60
So it's a simple comparison with the Samsung 128G TF card
The reader uses the Chuanyu C396, a bargain, but it feels quite handy, and it doesn’t know if it will cause a bottleneck.
Chuanyu Reader sd card SLR camera tf phone memory card multi-function card reader 3.0 high speed 19.89 yuan Lynx featured direct link The official flagship store, when the starting price was 12.9, it is said that some local preferential prices can reach 10 or less
For the 3.0 speed card reader this price is very good
Which will see the ATTO run points
Stable at about 94/84, I do not know whether the card, card reader or motherboard speed reached the limit.
AS SSD running points
128G refers to the Samsung 128G EVO+ upgraded TF card, and 32G refers to Toshiba EXCERIA 32G (w:90, r:60). Same as below
Toshiba doesn't know if it's a bit old
(PS. The speed of each card is also read and written by this software.)
Multiple photo copies, average size around 5-7m
128G is stable at about 33m/s, 32G is stable at about 28m/s
2.82G single large file copy test
128G is stable at about 75m/s, 32G is stable at about 55m/s
Try another platform
Reading speed on the phone is reduced
There is still a gap between UFS2.0 and it
Here to praise the maverick LG
Old flagship G5 supports memory card expansion + replaceable battery
Although the new flagship G6 can not replace the battery but still retain TF card expansion
Finally talk about the added value of SDXC cards
Such as my hand, this RX100M3, black card 3
64G and above memory cards must be inserted to enable XAVC S and 720p 100fps
The previous cards were 32G, 16G, and they didn't enjoy these functions
Finally I can try it today
Although 720p 120fps is not really more brilliant parameters now
Even many mobile phones can exceed this rate
But after all, an inch of “big machineâ€, the quality of the video shot in theory will be better.
I can't think of any other creative screens for a while. I can only play with a lighter.
In a nutshell: It's not a good time to buy a storage device
If you really need it, look at Aunt's push here, maybe it will be cheaper for two or thirty pieces.
In addition, consumers now learn smart and will not easily be fooled by business advertisements. If you are optimistic about which card
Look at the reviews of various platforms, and generally people will be ATTO's speed results
After browsing some of my own heart may have bottomed
Probably so
END.
