umm.. in the price comparison table, it has the second lowest $/GB. It only has the highest outright price because it has the highest capacity - double the nearest.
umm... the 400GB Sandisk isn't in the chart. The last paragraph of the article specifically says:
The SanDisk Ultra microSDXC UHS-I card ($153 at $0.3825/GB) also targets the same market segment with a similar speed rating, and it has a significantly lower per-GB cost.
Right now the Sandisk is only $142. It costs 60% less and is only 20% lower capacity.
What's up with the comma after every "but"? Makes for really annoying reading.
A few of them are correct, but most are not (see, no comma). Really the only reason there would be a comma after a "but" is a parenthetical statement, as in "PNY claims speeds of up to 90 MBps, but, as the speed ratings (Class 10 / U1 / V10) indicate, this is only for the reads."
Device manufacturers should stop crippling their devices by limiting it to 4k @ 30 fps and low bit rates. Only a Pro with the expensive tools can make use of these capacities.
I agree, and the fact that only the most recent (and costliest) Android phones just now introduced 4k60p video capabilities (Sammy's Newest) while Apple's iPhones had it for over a year is downright shameful. The absence of better video capabilities is one reason why I don't consider the newest (2018/19) Kirin 980 Huawei flagship phones actual "flagships" - they're stuck at 4kp30, w/o full stabilization.
Half a terabyte on a fingernail and people here only complain about price?
My first experience at removable media were 5MB RK05 and 10MB DL10 on a PDP-11/34: You needed both hands to carry those!
And just how many of these could you fit into a RAIF inside the physical form factor of current 14TB hard disks? Is there any CPU out there that could come even close to saturate the bandwidth of such a wide RAIF? At least latency is still a bucket of cold water...
On the other hand I remember dropping a 4GB microSD somewhere sitting on my sofa and my frustration because I couldn't find or dig it out again: Too small!
I'm not too anxious handling or even loosing 32GB microSD cards these days: They are the new floppy disks, but the thought of losing half a tera of family pictures at a slight bend, makes me cringe.
These 2.5" SATA FF units have a much bigger feel of solidity, even if on the insides these days they are mostly just thin air.
RAIF? Or RAID? Regardless, you'll find that even a RAID array of these wouldn't perform very well. I don't think there are any good RAID controllers for SD cards AND you'll get less-than-perfect scaling of ~20MBps writes and ~90MBps reads.
You can bring up "wow things are so much more advanced!" but this is still a halo product that is meant for a small niche of people that can afford to pay out the nose for the absolutely highest capacity and don't mind waiting literally hours to write a full disk.
@ Ganesh: Thanks for the review. I have two points: One, it's really odd that the 400 GB SanDisk card is not listed in comparison table. If you don't have your own speed data, just add a "not tested by Anandtech" to a foot note and put an "*" in the table where the data are missing. Second: the test is great, but this is NOT the most common use scenario for such large capacity microSDs. I would have appreciated a paragraph or two on whether and how well it worked with some widely used smartphones (Sammy's, OnePlus 6, LG V30, or whatever else you have ready access to), what read/write speeds it had there, and whether it worked okay if you recorded 4K video directly to the card. Similarly, pop the thing into a newer camera, either GoPro or similar, and let us know if the card worked not when recording in highest bit setting for 5 minutes or longer (4k 30p or 60p, if available) and similarly how it deals with a fast series of full-size photos. Those usage scenarios are really why most people who'd buy one would plunk down their cash for a really large capacity microSD. I still have a 200 Gb Sandisk card bought on the heap, but can always use more space for video (:
The UX with smartphone applications is brought out in the PCMark8 storage bench results. We have reason to believe that the storage access trace for mobile applications will be similar to the ones seen in the PC space, and the PCMark8 workloads presented give those numbers.
For 4K recording, my suggestion is always to see the maximum bitrate at which the cameras record, and see if the card has the minimum sustained speeds in our fio sequential write workload - the max. bitrate will be different for different phones.
High-capacity microSDXC cards have started to appear in the market, thanks to the advent of 3D NAND. In August 2017, the 400GB SanDisk Ultra microSDXC UHS-I card was introduced. At the 2018 Computex, we saw multiple vendors (ADATA, PNY, and Team Group) demonstrating 512GB microSDXC cards. To know more visit - https://www.applesupportphonenumbers.com/blog/fix-...

You're absolutely right and now I cannot ignore all of the extra commas.zodiacfml - Wednesday, September 19, 2018 - link

The RK05 (the removable disk) was 2.4MB - the fixed version (RK05F) was 4.8MB.I remember having to carry a complete RK05 drive (not just the disk) - it was HEAVY.
