Modern laptops might've tried to kill off the built-in optical drive, but physical media is far from dead. Case in point: the Dell DW316 Slim external USB DVD-RW drive for $39 at Amazon.

Physical media is making a serious comeback (my hardware editor, with his massive library of films, games, and books, argues that it never went away). In fact, this Dell USB writer proved essential when I wanted to watch my wedding video from 20 years ago, which was locked on DVD.

If you need to rip CDs and DVDs, access archived files, or just kick back and watch a movie, the USB-powered Dell DW316 is an easy recommendation from me.

• Dell DW316 is also available for $40 (was $50) at Best Buy.

Why we recommend it

I put the Dell DW316 to good use myself this year when my wife and I celebrated our 20th wedding anniversary. As I mentioned, our wedding video is still on DVD and this gave us an easy way to watch it again.

Beyond digital nostalgia, it's a really practical upgrade to access older software, music, movies and other physical media that would otherwise be left gathering dust.

And unlike files stored on a computer, in the cloud or on a storage device, data burned to a write-once disc can't be accidentally deleted, overwritten or changed, giving you a permanent physical copy. Write-once media can create a physical copy of important documents, photos or other files that can be kept offline and separate from your computer.

The drive is just 14mm thick and weighs 200g. Power comes directly from your laptop's USB port, eliminating the need for a separate power adapter. It can also create discs using CyberLink Media Suite 12 which comes supplied free.

Price context & historical value

This drive has never been priced above $52 (at least, not since 2015), while its lowest price was $16 back in 2020. General trends show it more or less holds its price at around the $35 to $40 mark. For comparison, Dell's external disc drive is also available at the same price, $40 (was $50) at Best Buy.

Should you buy it?

✅ Buy the Dell DW316 if...

You occasionally need to access old CDs, DVDs or disc-based software, or want an inexpensive way to create physical copies of important files. The drive's small size means you can keep it tucked away until you actually need it.

❌ Skip the Dell DW316 if...

You need Blu-ray support or regularly work with large amounts of data. DVDs have limited capacity compared with modern storage devices, and this drive can't read or write Blu-rays.

The Catch: What to know before you buy

The DW316 connects over USB and is an older optical-drive design, so don't expect the transfer speeds you'd get from an external SSD or flash drive. Its purpose is accessing and creating optical media rather than moving large files quickly.

You'll also need compatible blank writable discs if you intend to use it for backups or archiving, adding a small additional cost on top of the $35 price.

Data centers across the United States have been criticized for harming local environments sourcing power - sometimes illegally - from gas burning turbines that can release harmful pollutants into the air surrounding local communities.

But dozens of data centers have been accused of releasing harmful chemicals, heavy metals, and rare bacteria with the wastewater they release into nearby treatment facilities and waterways.

Violations have been logged for data centers in Wyoming, Virginia, New York, and Georgia, but the problem likely extends far across the rest of the US. Information on water usage and discharge for many data centers is hard to come by - or is being actively blocked.

Pollutants released into water across the US

In Wyoming, Meta was recently forced to halt water discharges from the construction site of its enormous 960-acre Cheyenne campus after a resistant bacterium - Cupriavidus gilardii - was found within a local water treatment facility.

The bacterium was identified after regulators tested a sample of the 801,000 gallons Meta had discharged into Cheyenne’s sewers. Following concerns that local residents could inhale droplets of the contaminated water if it was used for irrigation, local officials decided to stop accepting wastewater from the construction site.

Two water treatment facilities were forced offline as part of a multi-month decontamination and cleanup operation. Meta’s contractor responsible for the site, Goat Systems, is appealing the decision of officials to stop accepting wastewater from the site.

Multiple data centers across Virginia are facing enforcement actions from local authorities for violating wastewater and wetland regulations. In one such case, a data center under construction in West Virginia has funneled stormwater runoff into a local residential area, causing flooding on two occasions.

A data center near Lake Seneca, New York, is facing criticism from the Seneca Lake Guardian organization. The site was previously a cryptocurrency mining data center, but has been transitioning towards handling AI workloads instead. Seneca Lake Guardian has said that wastewater from the site flows directly into Lake Seneca at temperatures of up to 108F (42C), which can harm fish living in the lake and cause blooms of toxic algae.

The company behind the data center, Vulcan Infrastructure and Power, says it complies with all relevant environmental laws.

Multiple new data centers in Georgia have been approved to draw water from the Chattahoochee river, but local environmental guardians, such as water policy director at Chattahoochee Riverkeeper, Chris Manganiello, are being blindsided by a complete lack of information on how much water will be taken from the river, and what will be put back in.

“We need to know what is in this wastewater but there is a void of information,” Mangeniello told The Guardian. “I would like there to not be more Pfas [forever chemicals] going into the river but there is this level of anxiety because we don’t know what’s there.”

Don’t throw the Pfas out with the cooling water

Data centers pump water through miles of pipes crisscrossing their hardware in order to draw away excess heat. While there have been moves towards “closed-loop” cooling technology - where the water used is recycled within the system - there are still valid environmental concerns associated with these systems.

Before using a closed-loop system, the pipes need to be flushed through with water to wash away any debris or contaminants that were deposited within the pipes during assembly. This water is then released back into sewers to be cleaned by local treatment plants.

But many water treatment plants simply aren’t built to handle filtering water that contains industrial contaminants. These contaminants can include heavy metals or Pfas that can cause health problems in humans and animals.

Data centers are also being built in drought-hit regions, largely because the land is cheap, placing additional strain on already struggling water tables. Data centers can use hundreds of thousands of gallons of water per day to stay operational, and while closed-loop systems ensure this water is only taken out of the cycle once, it is still a significant sum of water to remove from regions experiencing droughts.

• Microsoft has fixed no fewer than 974 vulnerabilities in its latest Patch Tuesday release
• Two were already being exploited in the wild, 114 categorized as 'Critical'
• AI is to blame for boosting CVE discovery and also intensifying attacks

Microsoft's September 2026 Patch Tuesday has become its biggest security release on record, with the company issuing fixes for a staggering 974 vulnerabilities across the entire stack.

According to the company's release notes, an overwhelming majority (723) of the vulnerabilities addressed related to Windows, with Office coming in at second place with 111 of its own vulnerabilities being addressed.

While it's clear that the number of vulnerabilities is going up year-over-year, it's likely that the company was also simply able to find more of them that would otherwise have slipped through the net thanks to AI-assisted discovery tools.

This is Microsoft's biggest Patch Tuesday ever

Speaking about the September 2026 Patch Tuesday in a blog post, Dustin Childs explains that this could be the start of the "new normal." Childs goes on to reveal that Microsoft has patched 2,760 CVEs this year to date – more than double any other year that precedes it.

Childs' figures show that the company patched 1,139 CVEs in the whole of 2025, and a much lower 492 a decade ago in 2016. According to the post, 114 of the vulnerabilities patched in this latest update were 'Critical' – more than one in 10.

In its own notes, Microsoft described CVE-2026-85880 and CVE-2026-81963 as especially notable because they're both being actively exploited, hence the push to get them fixed and for customers to install the update.

Elsewhere in the industry, Microsoft isn't the only company addressing a higher volume of bugs. Childs also highlighted high activity from Adobe, while a number of browser developers including Google, Mozilla, Brave and Microsoft itself have doubled the release cycle to two weeks in order to get fixes into customer hands more quickly.

Besides fixing exploitable bugs, Microsoft also used the opportunity to issue fixes to known issues – including fixing Teams and Outlook crashes on Arm64 PCs – as well as to upgrade Copilot+ AI components.
