Bottom Line | While not the fastest, it excels in every aspect at a relatively low price | Great performance from a portable scanner that isn't to bad on the wallet | Great performance for infrequent tasks, but not great for large tasks that require auto feeding and higher speeds | While probably sufficient for most, this portable model is not a great option for the home office | You can give it a try without any risk, and packs a lot of performance into a phone app, but isn't great for longer documents |

Our Analysis and Test Results
The Brother DS-640 provides quality, portability, and usability in spades, with speed being its only relative weak point. Unless you're scanning 10+ page documents on a daily basis, chances are the Brother DS-640 will provide more than you need at a reasonable price.
Performance Comparison
Scanning Performance
The Brother DS-640 provides some of the best scan quality per dollar of any of the models we've tested. It often matches the quality of the expensive large office-focused models at a fraction of the price.
The PDFs we created came out looking nearly identical to the originals for general text scans. Even the ink on receipts, which can be problematic for scanners, didn't pose any problem for the DS-640.
The color scans we created in our testing looked fantastic. The colors were accurate and vibrant, and the resolution remained crystal clear. We were more than satisfied with the color documents we scanned with this model.
Photo scans came out similarly high quality, although the Brother DS-640 can't match the quality of a flatbed scanner when it comes to photos. You may not want to feed a treasured old photo through it, but it can get the job done in a pinch.
Speed
The Brother DS-640 isn't particularly fast, but that's because it has neither duplex scanning nor a document feeder. However, it's more than serviceable for documents less than ten pages.
In our tests, the Brother DS-640 took 30 seconds to scan a single color page at 600 dpi (a very high resolution), which is just above the 24-second average of all the tested models.
Longer, duplex documents are where things get a bit slow. Since you have to manually feed each page into the scanner, scan times for longer documents add up. Additionally, this scanner can only scan one side of a sheet at a time, so double-sided pages have to be fed through twice to scan both sides, doubling the amount of time and effort you have to put in.
In our tests, scanning a 10-page duplex black and white document (that's five sheets with text on both sides of each sheet) took 2 minutes and 30 seconds. In comparison, scanners that can scan both sides of the sheet at once easily accomplished the same task in under 30 seconds. This difference in time isn't terrible if you only scan a few 10-page documents a week, but if that's a regular occurrence, then the extra minutes can add up.
Software
In general, we liked the software associated with the Brother DS-640. We found its installation and operation to be straightforward and reliable on both Macs and PCs.
Perhaps most importantly, the included optical character recognition (OCR) software for both PCs and Macs proved to be more than capable in our tests. It consistently converted text pages into text-searchable PDFs without conspicuous errors.
Ease of Use
The Brother weighs in at just over a pound, can be powered by a USB port, and features smooth paper feeding. It doesn't get much easier than that. The only place it gets bogged down is when scanning longer documents. Unfortunately, the lack of duplex scanning and an automatic document feeder makes scanning long documents a chore.
Should You Buy the Brother DS-640?
The Brother DS-640 is, in our opinion, the perfect solution for those that need high-quality scans but who don't tend to scan super long (10+ page) documents all that frequently. If this sounds like you, then we highly recommend making this the newest addition to your home or office workspace.
What Other Scanners Should You Consider?
The Brother DS-640 offers a fantastic value for those who only need to scan shorter documents a few times a week relative to other models in our scanner review. You get top-quality results for a fraction of the price of more capable models, all in a small and convenient package. However, if you're consistently scanning 10+ page documents multiple times a week, you'll likely want to upgrade to a model with an automatic document feeder. Depending on your scanning volume, the Fujitsu ScanSnap iX1600 or the Fujitsu Fi-8170 are both great options to consider. Especially if you are using this in a work environment rather than a casual home setting, the extra cost will likely pay for itself in saved time in the long run.
