AdvertisementA small design is great, but a portable SSD should be durable as well. All of the portable SSDs we tested fit that bill. Most portable SSDs can easily fit in one hand, and some donвЂ™t even extend past the confines of your palm. Size and durabilityA portable SSD should be small enough to fit into your daily bag comfortably without displacing any of your other necessary items. ItвЂ™s another roadblock that can keep unauthorized users away from your private data, so itвЂ™s worth employingвЂ”just make sure to keep that password at the forefront of your mind. In general, we recommend protecting all of your devices with some form of a password and portable SSDs are no exception.

However, if you need extra space for professional work, be it high-quality RAW images, big data sets, system backups, and the like, itвЂ™s worth it to get a 1TB or larger SSD.Most portable SSDs start at 250GB and max out at 2TB. If you need more space for personal file-and-photo spillover from your PC, you may make do with a 250GB or a 500GB SSD. CapacityThere are a number of factors that contribute to how much extra storage you may need, key among them being what you plan on using your new portable SSD for and your desired price range. If you plan to travel a lot with your portable SSD or to take the device into extreme climates, look for a device that has higher levels of elemental resistance. Look for a portable SSD that has some physical safeguardsвЂ”a protective case, a drop-resistant design, or something similarвЂ”so your data remains safe and sound even during unexpected situations.

The devices we tested ranged from 250GB to 2TB in capacity and they cost between $70 and $500. PricePortable SSD price is directly related to capacity: the more storage you need, the more you can expect to spend. The more storage you need, the more money you should expect to spend on a portable SSD.

While write scores provide a better picture of the SSDs capabilities when under extreme pressure, read scores are also informative and good to have for comparison. Check out our primer on fio to learn how to install it on your system, and even more about the right way to benchmark storage.We tested read and write scores for each portable SSD using the following tests. That may be foreign to some who aren't used to using the command line, but it's a convenient and free way that anyone can use to benchmark internal and external storage solutions they have.

Find out the open source way, with fioAs explained at length by Ars' Technology Reporter Jim Salter, anyone can use fio to test storage read and write performanceвЂ”all you need to do is install it via the command line. Testing methodologyThe materials used for our benchmark testing consisted of many portable SSDs, the USB-C cables they came with, my 2017 13-inch MacBook Pro (Core i5, 16GB RAM, 512GB SSD), and the open-source tool Flexible IO tester (fio). We found the sweet spot in terms of pricing to be between $80 and $200, and that's encouraging because it means you don't have to spend a fortune to get a solid, durable SSD with ample storage.

This test simulates a machine that's doing a bunch of things at once, rather than one incredibly laborious thing and nothing else. Test 2: 16 parallel 64k random read/writeFio -name=random-read -ioengine=posixaio -rw=randread -bs=64k -size=256m -numjobs=16 -iodepth=16 -runtime=60 -time_basedВ -end_fsync=1Fio -name=random-write -ioengine=posixaio -rw=randwrite -bs=64k -size=256m -numjobs=16 -iodepth=16 -runtime=60 -time_basedВ -end_fsync=1Here, we're reading/writing 16 separate files using 64KB block-sized random write operations. It simulates copying home directories, manipulating email processes, database operations, and more. While this is a taxing test overall, it's a particularly brutal write test. Test 1: Single 4K random read/writeFio -name=random-read -ioengine=posixaio -rw=randread -bs=4k -size=4g -numjobs=1 -iodepth=1 -runtime=60 -time_basedВ -end_fsync=1Fio -name=random-write -ioengine=posixaio -rw=randwrite -bs=4k -size=4g -numjobs=1 -iodepth=1 -runtime=60 -time_basedВ -end_fsync=1This is a single-process test that performs a random read/write of a 4G file in 4K block-sizes to the SSD.

We ran each test three times and averaged the results to get the results you'll see in our benchmark charts. Before each read test, we also purged the cache to make sure it wasn't influencing the final scores. This is a good indicator of an SSD's upper-end performance.As indicated in our fio code, all of the above tests ran for one minute and we added -end_fsync=1 to ensure that the results were reported only when the SSD actually completed reading or writing the entirety of the file(s). Test 3: Single 1MB random read/writeFio -name=random-read -ioengine=posixaio -rw=randread -bs=1m -size=4g -numjobs=1 -iodepth=1 -runtime=60 -time_basedВ -end_fsync=1Fio -name=random-write -ioengine=posixaio -rw=randwrite -bs=1m -size=4g -numjobs=1 -iodepth=1 -runtime=60 -time_basedВ -end_fsync=1Our final test reads/writes a file in 1M block sizes, and like with our previous test, we ran this with various file sizes to see how much the SSDs could take before slowing to a crawl. We also ran this as a single-process test (resulting in one file instead of 16 separate files) after we saw most of our SSDs produce very low scores (particularly write scores) on the 16-parallel test.
