NAND, WiFi & Camera Performance
My MeMO Pad HD7 review sample included a 16GB SK Hynix eNAND eMMC 4.41 solution on-board. Internally there are two 64Gbit NAND die (2y nm class, 20 - 30nm), likely 2bpc MLC given Hynix's position on waiting for TLC until the 1y-nm node.
The eMMC is new enough to support TRIM, however the MeMO Pad HD7 ships with Android 4.2.2 which doesn't include support for fstrim. Presumably once the HD7 gets updated to Android 4.3 we'll see fstrim enabled as the hardware should support it. We really need to see better eMMC solutions focusing on improving random write performance. Even when constrained to a 100MB space the random write performance of pretty much every modern Android device is horrible at best. And what you're looking at here is best case performance. Fill the eMMC and you'll see significantly worse performance over time. The only recommendation I can offer is to keep at least 25% of your internal storage free. I haven't done much digging to see how these bargain basement eMMC solutions behave over time when given tons of spare area, so it's possible that the 25% recommendation may not be enough. I've started some experimentation with the Nexus 7 and I hope to have something to report in the not too distant future.
Quite possibly the biggest tradeoff/drawback, the MeMO Pad HD7 only features a single antenna 2.4GHz 802.11n WiFi solution. WiFi is provided courtesy of MediaTek's own MT6628 WiFi/BT/GPS/FM combo chip.
Its peak performance is actually really good though:
Although GPS is supported by the MT6628, GPS isn't enabled on the HD7. Update: I was very wrong here. GPS is supported and enabled on the MeMO Pad HD7. Sorry!
The 5MP rear facing camera is a nice addition over the original Nexus 7. Image quality is reasonable in a pinch. ASUS' camera UI is nice and quick, with a high framerate downsampled preview. As always, toss enough light on the subject and the results can be pretty decent:

Can you guys run more kinds of WiFi tests on your review devices? Peak throughput is as useful as only showing sequential SSD writes/reads. Can you show how the throughput and latency changes over time especially when there's some sort of interference (ie. microwaves, other WiFi access points, cordless phones, etc.).All too often my Skype calls and Netflix videos get forced into a lower quality whenever my WiFi gets burps. Depending on the device (ie. single atenna vs 3 antennas), the frequency of my WiFi spazzing vairous. Of course, I get the least amount of issues when connected via Ethernet.

Yeah I don't know what Google's problem is with SD slots. I'd take this thing over the Google-branded hardware.lightsout565 - Monday, July 29, 2013 - link
Very compelling but I'll wait till prices drop to $100. If someone could only make a decent $100 tablet, that'd almost be in "impulse buy" territory for me.Bob Todd - Tuesday, July 30, 2013 - link
I think it's worth noting that the price, although higher than the gen one 16GB Nexus 7 has been since before the iPad mini launch, is actually _cheaper_ than that device when it launched a year ago at $250. Getting a 1200p panel that's also higher quality, a much faster SOC, double the RAM (@1600 vs 1333), much faster storage, and bunch of other little things (rear facing camera, wireless charging, etc.) for $20 less than the 16GB N7 debuted with just one year ago is pretty impressive to me.As for this thing, I actually wish the 8GB model was available here. This looks like the perfect replacement for an old Nook Color that's used to keep a toddler entertained with movies in the car. Especially if it can read SDXC (even if it's the gimped non UHS 1 speed that some devices not rated for SDXC can read them at).

That should read..."noting that the price of the Nexus 7.2".Zibi - Tuesday, July 30, 2013 - link
I've just bought one for my father. Pretty decent thing. Unfortunately it hasn't got USB with OTG. During the brief playing with the thing I did not found the option to create user accounts.SirCanealot - Tuesday, July 30, 2013 - link
Sorry for the possibly silly question, but does anyone know what the cpu monitoring tool used in the screen shot in the battery test is? Looks awesome!skyline159 - Wednesday, July 31, 2013 - link
It is System Monitorhttps://play.google.com/store/apps/details?id=com....

Great article as expected Anand, what is the program you used to overlay the core usage/speed in game?Shadowmaster625 - Tuesday, July 30, 2013 - link
So basically this is what we can expect to pick up for $99 during holidays sales.
