SanDisk recently announced new microSDXC cards in 512GB and 1TB capacities that it claims are the fastest cards [soon to be] on the market. The SanDisk Extreme UHS-I micro SD cards conform to the C10/V30/U3/A2 speed classes (only USB-IF is more confusing heh) and are able to hit up to 160 MB/s reads and 90 MB/s write speeds reportedly thanks to Western Digital’s (who owns SanDisk) proprietary flash (though the PR and product page do not go into details on which version it is using it is likely some version of 96-layer BiCS flash).
In addition to transfer speeds, the micro SDXC UHS-1 cards offer A2 class enhanced application performance with up to 4,000 read IOPS and 2,000 write IOPS. As a result, the cards allegedly support faster load times and random access of applications run from the microSD card (e.g. Android applications installed to the expansion card rather than internal storage).
According to the product page, the cards are rated for temperatures ranging from -13F to 185F (cold is much worse for flash memory than heat) when in use and down to -40F when not in use.
It is impressive to see 1TB and even 512GB of storage available in such a small physical format when just a few years ago 64GB was considered large! Many smartphone do not even (officially) support higher than 256GB or less for their expandable storage though so long as the cards are formatted correctly these new cards should still work.
Brian Pridgeon, Director of Marketing for SanDisk at Western Digital was quoted in the press release in stating:
“People trust SanDisk-brand cards to capture and preserve their world. Our goal is to deliver the best possible experience so consumers can share the content that’s important to them,” said Brian Pridgeon, director of marketing for SanDisk-branded products, Western Digital.
4K UHD and soon enough 8K video recording on a smartphone or dedicated camera seems to be an obvious use case for these new higher capacity cards as well as the ability to sneakernet files and mail off data for offsite backups easily thanks to the tiny size and weight.
Note that a full card would take just over 2 hours to copy from card to computer and just over 3.5 hours to fill at maximum transfer speeds of 160 MB/s and 90 MB/s respectively. Western Digital's SanDisk Extreme UHS-I is slightly faster than Micron's 1TB microSD card in reads while the two are about even in writes with Micron's microSDXC card hitting up to 100 MB/s reads and 95 MB/s writes.
The increased storage space doesn’t come cheap though with MSRPs on the new micro SDXC cards being $199.99 for the 512GB UHS-I card and $499.99 for the 1TB model. SanDisk is offering the cards for pre-order on its website with wider retail availability expected April 2019.
Will you be picking up a 1TB microSD card? Personally, I’m still a ways away from filling up my 64GB mSD card though I do use Sync to copy my photos and videos off of my phone and regularly delete them from my phone. The wife might be able to make use of one of these high capacity cards since she’s constantly running out of space on her phone and needs to pay for cloud storage – if only she didn’t have an iPhone!

Today Samsung released an update to their EVO+ microSD card line. The new model is the 'EVO Plus'. Yes, I know, it's confusing to me as well, especially when trying to research the new vs. old iterations for this mini-review. Here's a few quick visual comparisons between both models:
On the left, we have the 'older' version of the Plus (I mean the '+'), while on the right we have the new plus, designated as a '2017 model' on the Samsung site. Note the rating differences between the two. The '+' on the left is rated at UHS-I U1 (10 MB/s minimum write speed), while the newer 'Plus' version is rated at UHS-I U3 (30 MB/s minimum write speed). I also ran across what looked like the older version packaging.
The packaging on the right is what we had in hand for this review. The image on the left was found at the Samsung website, and confuses things even further, as the 'Plus' on the package does not match the markings on the card itself ('+'). It looks as if Samsung may have silently updated the specs of the 256GB '+' model at some point in the recent past, as that model claims significantly faster write speeds (90 MB/s) than the older/other '+' models previously claimed (~20 MB/s). With that confusion out of the way, let's dig into the specs of this newest EVO Plus:
For clarification on the Speed Class and Grade, I direct you to our previous article covering those aspects in detail. For here I'll briefly state that the interface can handle 104 MB/s while the media itself is required to sustain a minimum of 30 MB/s of typical streaming recorded content. The specs go on to claim 100MB/s reads and 90 MB/s writes (60 MB/s for the 64GB model). Doing some quick checks, here's what I saw with some simple file copies to and from a 128GB EVO Plus:
Our figures didn't exceed the specified performance, but they came close, which more than satisfies their 'up to' claim, with over 80 MB/s writes and 93 MB/s reads. I was able to separately confirm 85-89 MB/s writes and 99 MB/s reads with Iometer accessing with 128KB sequential transfers.
- 32GB: $29.99
- 64GB: $49.99
- 128GB: $99.99
- 256GB: coming soon (but there is already a 256GB EVO+ of similar specs???)
Pricing seems to be running a bit high on these, with pricing running close to double of the previous version of this very same part (the EVO+ 128GB can be found for $50 at the time of this writing). Sure you are getting a U3 rated card with over four times the achievable write speed, but the reads are very similar, and if your camera only requires U1 speeds, the price premium does not seem to be worthwhile. It is also worth noting that even faster UHS-II spec cards that transfer at 150 MB/s can be had and even come with a reader at a lower cost.
In summary, the Samsung EVO Plus microSD cards look to be decent performers, but the pricing needs to come down some to be truly competitive in this space. I'd also like to see the product labeling and marketing a bit more clear between the '+' and the 'Plus' models, as they can easily confuse those not so familiar with SD card classes and grades. It also makes searching for them rather difficult, as most search engines parse 'Plus' interchangeably with '+', adding to the potential confusion.

A while back Al broke down the specifications of SD cards and what each class meant and the proper usage for them. The top class is U3 and it offers transfer speeds high enough to support recording 4K video on your devices and that happens to be the rating on the new 256GB Samsung EVO Plus MicroSD. Legion Hardware just tested this MicroSD card and it now holds the title of best performing SD card they have tested. The performance does come at a premium, the MSRP of the card is $250 and even with a 10 year warranty this is still an expensive purchase. If you need the ability to record 4K video immediately this is the fast solution available but if you are still in the planning stages, remember that there is a new standard, UFS, which is due to hit the market soon and impact pricing of older products.
"Running out of storage on your smartphone, tablet or 4K video camera? Well the good news is SD cards have never been more affordable and crucially offered such huge storage capacities. In fact, Samsung recently announced the availability of a 256GB version of their popular EVO Plus MicroSD card series"

Samsung just announced the first product based on the new Universal Flash Storage standard which will be making microSD cards as obsolete as your old mix tape. They will come in sizes from 256GB down to 32GB but it is the speed of these new storage devices that will impress, not the density. Samsung tells of sequential read speeds of up to 530MB/s, allowing you to dump HD quality video to a PC and random reads of 40,000 IOPS if you have a usage scenario which would read in such a manner. For recording video you can expect up to 170MB/s sequential write speed or 35,000 random IOPS; 4K drone recordings won't be limited by bandwidth anymore.
Unfortunately, as The Inquirer points out, no one can use these yet as we haven't a place to stick them.
"What UFS does mean already is that we'll start to see a bottleneck lifted in storage speeds in phones and tablets. As we've already seen, MicroSD doesn't cut it in the speed stakes, and it doesn't seem so long ago that we reported on torn down phones with 'internal' memory that was really just an SD card hidden away."

Lexar (Micron's portable media brand) is known for their versatile flash media readers and lines of portable flash memory products. Today they have updated two of their big SD Card lines. First up is their 2000x (300MB/s) product, which now comes in a 128GB capacity:
As we pointed out in our SD Card Speed Classes, Grades, Bus Modes, and File Systems Explained piece, cameras and video recorders most likely won't use that super high 250MB/s write speed, but emptying a 128GB card at 300MB/s will take only 7 minutes (provided your destination device can write that fast)! This model comes with a small USB 3.0 reader, which makes sense as most systems can't hit 300MB/s with their built-in readers!
Next up is a HUGE capacity introduced in their 633x line:
This model may be less than half the speed of the 2000x part above, but 95 MB/s is not too shabby considering this card can store a half a TB! Write speeds are a bit more limited as well, coming in at 45MB/s. The use case for this card is as a full-time backup slot for capable SLRs, or more commonly (I believe) as a semi-permanent secondary storage addition to Ultrabooks. The cost at $0.54/GB comes in far less than the internal storage upgrade prices of many laptops.
Lexar also updated their CFast lines with faster (3500x / 3600x) models, as well as their XQD lines (1400x / 2933x). Lastly, the Professional Workflow XR2 (XQD 2.0) and UR2 (microSD UHS-II) pods are now available.
Stand by for a review of the 633x 512GB SD Card as we have one in for testing!
What you never knew you didn't know
While researching a few upcoming SD / microSD product reviews here at PC Perspective, I quickly found myself swimming in a sea of ratings and specifications. This write up was initially meant to explain and clarify these items, but it quickly grew into a reference too large to include in every SD card article, so I have spun it off here as a standalone reference. We hope it is as useful to you as it will be to our upcoming SD card reviews.
SD card speed ratings are a bit of a mess, so I'm going to do my best to clear things up here. I'll start with classes and grades. These are specs that define the *minimum* speed a given SD card should meet when reading or writing (both directions are used for the test). As with all flash devices, the write speed tends to be the more limiting factor. Without getting into gory detail, the tests used assume mostly sequential large writes and random reads occurring at no smaller than the minimum memory unit of the card (typically 512KB). The tests match the typical use case of an SD card, which is typically writing larger files (or sequential video streams), with minimal small writes (file table updates, etc).
In the above chart, we see speed 'Class' 2, 4, 6, and 10. The SD card spec calls out very specific requirements for these specs, but the gist of it is that an unfragmented SD card will be able to write at a minimum MB/s corresponding to its rated class (e.g. Class 6 = 6 MB/s minimum transfer speed). The workload specified is meant to represent a typical media device writing to an SD card, with buffering to account for slower FAT table updates (small writes). With higher bus speed modes (more on that later), we also get higher classes. Older cards that are not rated under this spec are referred to as 'Class 0'.
As we move higher than Class 10, we get to U1 and U3, which are referred to as UHS Speed Grades (contrary to the above table which states 'Class') in the SD card specification. The changeover from Class to Grade has something to do with speed modes, which also relates with the standard capacity of the card being used:
U1 and U3 correspond to 10 and 30 MB/s minimums, but the test conditions are slightly different for these specs (so Class 10 is not *exactly* the same as a U1 rating, even though they both equate to 10 MB/sec). Cards not performing to U1 are classified as 'Speed Grade 0'. One final note here is that a U rating also implies a UHS speed mode (see the next section).
Introduction, Specifications, and Packaging
Lexar is Micron’s brand covering SD Cards, microSD Cards, USB flash drives, and card readers. Their card readers are known for being able to push high in the various speed grades, typically allowing transfers (for capable SD cards) much faster than what a typical built-in laptop or PC SD card reader is capable of. Today we will take a look at the Lexar ‘Professional Workflow’ line of flash memory connectivity options from Lexar.
This is essentially a four-bay hub device that can accept various card readers or other types of devices (a USB flash storage device as opposed to just a reader, for example). The available readers range from SD to CF to Professional Grade CFast cards capable of over 500 MB/sec.
We will be looking at the following items today:
- Professional Workflow HR2
- Four-bay Thunderbolt™ 2/USB 3.0 reader and storage drive hub
- Professional Workflow UR1
- Three-slot microSDHC™/microSDXC™ UHS-I USB 3.0 reader
- Professional Workflow SR1
- SDHC™/SDXC™ UHS-I USB 3.0 reader
- Professional Workflow CFR1
- CompactFlash® USB 3.0 reader
- Professional Workflow DD256
- 256GB USB 3.0 Storage Drive
Note that since we were sampled these items, Lexar has begun shipping a newer version of the SR1. The SR2 is a SDHC™/SDXC™ UHS-II USB 3.0 reader. Since we had no UHS-II SD cards available to test, this difference would not impact any of our testing speed results. There is also an HR1 model which has only USB 3.0 support and no Thunderbolt, coming in at a significantly lower cost when compared with the HR2 (more on that later).

It is common knowledge that technology gets smaller as time advances. There is, however, a point where a certain level of advancement trots along the border to absurdity and makes you think about exactly what is possible with modern technology and occasionally an innovative spirit. Leave it to the hackers to consistently push that boundary and entertain the rest of us less talented individuals.
