If capacity is what you are after, then 5TB is the maximum you will get for a portable drive. 22TB is the largest single-drive capacity currently on the market (as of November 2022). If you want even higher capacities, you may want to consider Network Attached Storage ( NAS) which can scale all the way to hundreds of Terabytes. Over the years, I have reviewed iPad and iPhone science apps, plus the occasional camera, laptop, keyboard, and mouse. I've also written a host of articles about astronomy, space science, travel photography, and astrophotography for PCMag and its past and present sibling publications (among them, Mashable and ExtremeTech), as well as for the PCMag Digital Edition.

Compact and handy, it's ideal for long journeys or holidays. Simply pop them in the bag and carry it wherever you go, it will make sure your memories are stored and protected so that you can cherish them later. If you need to store data on your computer, then our desktop external hard drive is an ideal choice. Our collection offers storage up to 8 TB. Save files in a single location or you can even free the space on the internal drive of your computer for better performance. From SSD hard drives to HDD hard drives, we have a lot in our collection. Not sure which one to get? Browse our hard drive guide and get all the information you need with your tech queries.

Just how much faster is it to access data stored in flash cells? Typical read and write speeds for consumer drives with spinning platters are in the 100MBps to 200MBps range, depending on platter densities and whether they spin at 5,400rpm (more common) or 7,200rpm (less common). External SSDs offer at least twice that speed and now, often much more, with typical results on our benchmark tests in excess of 400MBps for the slowest ones. Practically speaking, this means you can move gigabytes of data (say, a 4GB feature-length film, or a year's worth of family photos) to an external SSD in seconds rather than the minutes it would take with an external spinning drive. Just recently, theSeagate (STEL10000400)had a drastic reduction in price 36% off the original amount. Although we’re unsure if this discount is permanent or temporary, we believe it’s a remarkable 10TB external hard drive. It provides two USB 3.0 ports and a 2-year limited warranty. Remember that this is a portable hard drive, which means that you can easily carry it around. It is not bulky as a desktop hard drive and doesn't need an external power supply. The drive we reviewed is the largest of the range and features Seagate's Dashboard software, compatible with Windows and Mac OS. Therefore you need to be able to compare benchmark results as best you can, but that means you need sufficent details on the critical parameters used. Data recording frequency? (your charts are smooth lines, without any points to indicate the datum points). Do you do it 1 or two datum points per second, or is it by data volume, as in 1 datum per GB or so?

The best external SSDs to buy

This means that much of the speed will be wasted on the Xbox Series S/X and PS5 consoles, where the P50 could be used to store games you aren’t playing or run last-generation titles. On a fast PC with the right connection, though, it’s an absolute beast. It’s also happy working in the most demanding content creation apps, making it one powerful and versatile external drive. Cloud functionality, which allows individuals and businesses to operate a personal cloud. Essentially your very own cloud storage solution. are any of these practical to have a portable os installed on them and have it at usable speed?The differing SSDs would make no difference.

But with dozens of portable storage options available, how do you know which is the right external drive to buy? Should you opt for a speedier, more rugged (and more expensive) external SSD instead of a portable hard drive made up of comparatively fragile spinning platters and an actuator arm? Or could a slower, roomier and much cheaper portable hard drive be adequate for your storage needs? Maybe you should just get one of the best flash drives instead? Those drives are generally more compact and don't require a cable, but they're usually not as fast or roomy as external SSDs -- although the best flash drives are getting faster and roomier. It is also well suited as long-term multimedia storage hooked up to a PC or large-screen smart TV from Sony or a recent Samsung as well - some smart TVs support NTFS and FAT32 or NTFS and ExFat, very rarely do they support all three file systems. The only case with hard drives where the USB standard matters much is if you connect a drive to an old-style, low-bandwidth USB 2.0 port, which is better reserved for items like keyboards and mice. (Also, if it's a portable drive, that USB 2.0 port may not supply sufficient power to run the drive in the first place, so the speed shortfall may be moot.) Any remotely recent computer will have some faster USB 3-class ports, though.It has a USB-C connection concealed beneath a chunky rubber flap and plug, with a Type-A adaptor provided. Don’t expect much in the way of extreme speed – it’s rated at a max 140MB/sec, and we tested it at 119MB/sec read and 141MB/sec write – but this is more of a tank than a Ferrari. Most of us don’t need to splash out on a drive that offers this level of protection, but if you want to store big image and video files and want a drive that’s built to withstand most disasters, then the Armor ATD won’t let you down. READ NEXT: The best external hard drives for PS4 | The best external hard drives for Xbox One Should I buy an SSD? It would be nice if the people writing an article highlighting data transfer speeds knew the difference between a gigabyte (GB) and a gigabit (Gb). 1 GB = 8Gb!

That said, as a platter-based hard drive, it's best equipped to store a game library; you're better off loading the games you're currently playing from an SSD. If you conservatively figure an average game size of 100GB, the 4TB version tested here can hold about 40 titles, serving as the stylish main repository of your collection for years to come, and for a much more modest outlay than you'd spend on an SSD of similar capacity. Who It's For Provided you have a USB 3.2 Gen 2 2×2 PC or laptop you can expect read speeds in excess of 1700MB/sec, with write speeds around 30MB/sec slower. Over a straight USB 3.2 Gen 2 connection, both read and write speeds stabilise at around 965MB/sec, which isn’t a massive improvement over 2020’s 1050MB/sec model. Yet it’s the random read/write speeds that are really impressive, reaching up to 206MB/sec and 226MB/sec, making this a good drive for apps and games as well as media. Looking for maximum performance for your most demanding applications? This is one of the strongest options. In a nutshell, it is a storage device that contains an internal hard drive. The fact that there's two types of hard drives - 2.5-inch and 3.5-inch - means that there are also two types of external hard drives: larger desktop hard drives and smaller portable hard drives.SSDs are small and extremely robust, which makes them great for moving media libraries or big projects between PCs or transferring Steam games from your PC to your laptop. And with read speeds anywhere between 500MB/sec and a staggering 3.2GB/sec (with the right connectivity – see below), you’ll be amazed how fast these things can go. Transfers that used to take ten or 20 minutes suddenly happen in a minute or less. What kind of connectivity should I look for? Perhaps the only thing you don't need to pay all that much attention to is the warranty. Sounds counter-intuitive, perhaps? Sure, a long warranty is nice. But if your drive breaks because you dropped it, the warranty likely won't cover that, anyway. Even if the drive fails because of a manufacturing defect, most warranties simply replace the drive and don't cover the cost of recovery services that attempt to rescue your data from the broken drive. The real value lies in what's on your drive, not the drive itself. Just make sure you get an enclosure that matches your drive, be that SATA or NVMe. And also keep in mind that DIY external drives usually aren't sealed, so they're not as likely to stand up to dust and dampness as well as external SSDs and portable hard drives that are designed to do so. Finding Discounts on the Best External Storage Drives Thunderbolt ports, should you need to daisy-chain storage, devices and display. This is particularly useful at the high end of the market where creative professionals are particularly fond of this port The LaCie 2big RAID array promises the reliability and delivers the performance benefit you'd expect from 7,200rpm platters, magnified by the default RAID 0 setting, while the optional RAID 1 setting is available if you want data redundancy. (A JBOD mode is also available if you don't want to use RAID.) Who It's For

If you deal with any sensible information leaving it in an unencrypted drive is risky. While encryption can be done in software with a high degree of fine-tuning, nothing beats a purely hardware-based solution that frees you from the software-configuration complexities. The LED lights at the front of the drive light up green for USB 2.0 and blue for USB 3.0 connection. Its wraparound USB cable -permanently attached at one end saves you from losing the cable but if you need a longer cable you'll have to use a male/female cable in between. Over the Type-C connection you get sequential read speeds of 1090MB/sec and write speeds of 1050MB/sec, although these drop to 469MB/sec and 461MB/sec over the slower Type-A. Random read/write speeds are speedy either way, peaking at 262MB/sec and 241MB/sec. While it’s not in the same league for speed as the fastest USB 3.2 Gen 2×2 SSDs, it’s an effective all rounder at a price more of us can afford. Used as a USB Type-C drive, the SanDisk Pro G40 does nothing to justify its high price. Sequential read/write speeds (1,055MB/sec and 1,012MB/sec in our tests) are nothing special, and its random read/write speeds aren’t particularly fast. However, plug it into a Mac, or a laptop with a Thunderbolt 4 port, and you’ll unleash a monster. On Thunderbolt 4, the Pro G40 posted read speeds of 3.15GB/sec and write speeds of 2.6GB/sec, making it the fastest drive we’ve ever tested. And nothing else even gets close for random read/write speeds.

Whether you’re running out of storage space or in need of a fast backup, these speedy HDDs and SSDs will give you what you need

For mechanical hard disks, the very fastest drives max out at 2Gbits/sec so there’s no need to go beyond USB 3.2 Gen 1. Are there any extra features worth having?
