You may soon store your entire media collection on one SD card

A single SD card might someday be enough to hold your entire media collection, no matter how huge it is. The SD Association (the group that sets memory card standards) just announced a new format called SD Express, which adds PCI Express and NVMe interfaces to the cards.

One big takeaway here is that it ramps up data transfer speeds to as much as 985 MB per second. Even more impressively, the new format bumps the maximum capacity of SD cards from 2 TB to a whopping 128 TB -- an SD card could replace all of your hard drives, unless you need a faster transfer speed.

In real terms, you could squeeze more than 25,000 HD movies onto one SD card. Assuming a typical photo size is 500 kB, the highest-end SD card could house 256 million photos. It could hold 25.6 million songs; two will be enough to store Spotify's entire library of 35 million tunes.

More practically, SD cards with vastly greater storage capacities and transfer speeds than we've seen before should be a boon for video creators shooting in 4K, 8K or VR. But it's important to remember the 128 TB capacity is a theoretical limit. Even 1 TB cards are rare, and 512 GB cards cost hundreds of dollars. So, be prepared to take out a few mortgages if you want that 128 TB card, which is probably years away from hitting the market, if ever. Besides, finding a laptop with an SD slot instead of a MicroSD slot will be hard enough by that time.

Evernote cuts staff as user growth stalls

Image
Note-taking app Evernote has fallen on hard times of late, culminating in its latest spate of job cuts impacting 15 percent of its workforce (54 employees). CEO Chris O' Neil -- an ex-Googler who took the reins in 2015 -- announced the firings at an all-hands meeting earlier today, reports TechCrunch . In a message on the Evernote blog , O' Neill admitted he'd set "incredibly aggressive goals" for the company in 2018. He continued: "Going forward, we are streamlining certain functions, like sales, so we can continue to speed up and scale others, like product development and engineering." The layoffs follow an exec exodus just weeks ago and the company's recent brand refresh (complete with a refined logo and wordmark). But critics are more concerned about its product, especially the free tier, which they claim lacks the perks to

The best air conditioner

After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic

We won't see a 'universal' vape oil cartridge anytime soon

Image
Pre-loaded cartridges of cannabis concentrate are currently among the most popular means of consumption, and for good reason. They're discreet to use and easy to handle, a far cry from the dark days of 2016 when we had to dribble hash oil or load wax into narrow-mouthed vape pens by hand. But, frustratingly, an ever increasing number of oil cartridge manufacturers employ one-off design standards so that their products won't work with those of their competitors, thereby locking customers into proprietary ecosystems. We've already seen this with nicotine vaporizers -- which has a seen a massive rise in "pod systems" in the last few years, each outfitted with a unique canister and battery built to be incompatible with those of their competition. Is it too late for the burgeoning cannabis industry to set a universal standard for their product designs?
