Almost ten years ago Lexar announced it’s first 1GB SD card. Today Lexar announces their first 1TB SD card. My, how times have changed. A one GB card ten years ago cost about $125 and difficult to find at that capacity. The 1TB card announced today is $499. Doing a quick calculation means the price per Megabyte went from $0.12 cents all the way down to $0.0005 per Megabyte. Awesome!
If the price difference isn’t a big enough shock to you, consider the storage capacity increased this much, yet the form factor of the SD card has not changed.
This new Lexar card is a Class 10 device with transfer speeds over 95MB per second. Ideal for newer cameras capturing video in 4K.

Anyone in tech has seen the reports and news about USB sticks with a virus ruined a company network or infect computers. Google built a small and affective feature into their latest Chromebooks.
The USBGuard is a feature which blocks interaction between the mass storage device and the Chrome operating system. The OS will give power to the device, but not let data transmit.
The USBGuard blocks this activity when the Chromebook is in locked mode. When the Chromebook is not in lock mode, the USB will interact as expected as a read/write device.

Several years back we did a blog post about the difference between CRC Verification and Checksum Verification. You can see the original article here.
Today, we found a SlideShare of the same article.
Yubico YubiKey 4 appears to be an excellent device for a two-factor authentication solution. Two factor authentication means you need two things before gaining access. In this case, one piece of information is your password and the other piece is your finger print.
If you are using a password manager right now, (ie. Last Pass, Dashlane, etc) I would recommend getting this. The benefit of this device with a password manager is you can enable two factor authentication to add a new device capable of signing into your account.
This means if someone knows your password, it doesn’t really matter because they would also need your finger print. Understand that nearly all password managers conform to some sort of security protocol like FIDO U2F, smart card (PIV), OpenPGP, etc which in turn works with Yubikey.
For those in a situation where you plug devices into unknown USB ports, a USB data blocker is a good thing to have around. Or some call it the USB condom!
This is a physical device that sits between the USB host connection and your device. The data blocker enables the power pings of a USB socket, but not the data lines. This means your device will get the power it needs, but without the possibility of infection via data transfers.
For example, if you are at a client’s office and need to connect your device to a USB port and don’t want to risk anything, use the USB data blocker. You’ll get the power, but without the risk of spreading or getting a virus.
Not much use for those who surround themselves with a trusted environment, but for those on the move, I think it’s a great product.
