You should never lose data because an external USB hard drive fails. Ideally, you should have at least three copies of your photos stored on different media and at least one should be kept in a different place. Schofield’s Second Law of Computing states that data doesn’t really exist unless you have at least two copies of it. But with square corners and an antiquated, two-tone design, the drive isn’t a looker. And it finished near the bottom of all of our performance tests. Also know that you can find external drives that do way more than just store your data. Some include SD card readers to offload footage from a camera or drone in the field, while a few specialized models have built-in Wi-Fi and can double as a little media server, able to connect to more than one device at a time. For charging speeds we recorded the maximum wattage at which the cable could charge an Asus ROG Strix 15 gaming laptop over its USB-C port using USB-Power Delivery with an Aukey 100 watt USB-PD charger as the source while the laptop was under load.USB-PD today is limited to 100 watts (with a 240-watt spec on the way). Any USB-C to USB-C cable should handle 3 ampsat 20 volts, or 60 watts.All of the USB-C to USB-C cables fell into the standard 60-watt or 100-watt camps. USB cables can fail after prolonged use, though this is more likely to happen to the Micro USB cables used with mobile phones. External hard drive cables rarely fail unless they get the same sort of abuse. However, if you have two devices that use the same type of cable, you can swap them over to see if that solves the problem.

Ethernet is the same connection type that your computer uses to connect to its Internet device (cable or DSL modem, etc). In addition to their physical shape differences, USB ports on the computer side will variously support USB 3.0, 3.1, or 3.2, depending on the age of the computer and how up to date its marketing materials are. You don't have to worry about the differences among these three USB specs when looking at ordinary hard drives, though. All are inter-compatible, and you won't see a speed bump from one versus the other in the hard drive world. The drive platters' own speed is the limiter, not the flavor of USB 3.Connect the SATA cable to the port on the hard drive, then connect the other end of the cable to the motherboard, taking care not to disturb or impede the connection to the existing HDD Powered eSATA provides high performance like eSATA, but like USB 2.0 it also provides electrical power to operate a drive without needing to use a separate power cable for the drive. This interface is even more rare than eSATA. One of the types of FreeAgent GoFlex upgrade cables, which is compatible with the FreeAgent GoFlex and GoFlex Pro, uses the Powered eSATA interface.

FireWire comes in two speeds - FireWire 400 and FireWire 800. FireWire 400 (also known as 1394a) usually gives performance similar to USB 2.0. FireWire 800 (1394b) is significantly faster, giving performance similar to an internal Serial ATA drive, and is almost exclusively available in Mac computers. USB is supposedly universal, but there are so many different types of USB cables and connections. Why is this? As it turns out, they each serve different functions, mainly to preserve compatibility and support new devices. The output of the USB port (my MacPro front ports offer more power than the USB standard defines, on this ports, the 3 m cable works) The drive is a shade expensive, and the integrated carrying loop is too big to easily fit on a standard keychain.Otherwise, this is an excellent storage device that's ideal for heavy everyday use. ATA is a very common connection for internal drives in older PCs and older desktop Macs (before G5), and for devices like CD and DVD drives in modern PCs and Macs. It is a connector about 2 inches (5 cm) wide and has 40 small gold pins that will fit into the corresponding 40 small holes on its corresponding connector.Some external hard drives draw their power from the USB port and they may not get enough. This can be a problem if the PC’s motherboard does not supply enough power to the USB port you are using or if the drive is plugged into a non-powered hub. EHDs that have their own power supplies tend to work more reliably. We didn’t test the temperature of each cable’s housing, but we did test the cheapest cable by running it at 5 amps and 20 volts for an hour. The housing heated up by 50 degrees Fahrenheit, and the cable itself became relatively warm (see the thermal image below). Not ideal, but it did this without failure. We subjected other cables to two-hour loads without failure, as well.

You’d think you could tell whether a cable is USB-C 2.0 cable by looking at the wires in the connector but that’s not the case. Some cables use connectors with pins that aren’t hooked up to anything. See here a graphic of the eSATA cable and the port. Please note that the cable's connector and the port look similar to that of a normal Serial ATA connector and port, but they are not intercompatible due to small physical differences. Most such multi-bay devices are sold without the actual hard drives included, so you can install any drive you want (usually, 3.5-inch drives, but some support laptop-style 2.5-inchers). Their total storage capacities are limited only by their number of available bays and the capacities of the drives you put in them. The storage industry refers to these (as well as smaller-capacity externals as a whole) as DAS—for "direct attached storage"—to distinguish them from NAS, or network attached storage, many of which are also multi-bay devices that can take two or more drives that you supply. (See our separate roundup of the best NAS drives.) SATA cables are beneficial as their shape has been specifically designed to help maximise airflow inside a CPU, saving space and boosting performance. USB drives are just cheap hard drives in (usually) plastic enclosures. You can easily make your own by buying a big hard drive and a separate enclosure. If your EHD doesn’t work but you can hear the drive spin up when it is plugged in, you can try removing the hard drive and installing it in a new enclosure.

No matter what you want from the best external hard drive, the SanDisk Extreme Pro Portable SSD delivers it. 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.

We hooked up each external hard drive to a current-generation Dell XPS 17 laptop, using the best connection interface available to that drive, always in the same port, to minimize performance differentials.Lots of things can go wrong. The port, the connecting cable, the power supply and the external hard drive (EHD) can all suffer from physical and/or electrical faults. You'll only see the speed benefits of Thunderbolt, however, if you have a drive that's SSD-based, or a multi-drive, platter-based desktop DAS that is set up in a RAID array. For ordinary external hard drives, Thunderbolt is very much the exception, not the rule. It tends to show up mainly in products geared toward the Mac market. Try a different USB cable. If your external hard drive has a detachable USB cable, try a different one in case the cable has failed. Still, while external SSDs are cheaper than they were a few years ago (see the best we've tested at the preceding link), they're far from a complete replacement for spinning drives. Larger external drives designed to stay on your desk or in a server closet still almost exclusively use spinning-drive mechanisms, taking advantage of platter drives' much higher capacities and much lower prices compared with SSDs. The USB 3.0 cable has two ends - one to connect into the drive, and one to connect into the computer. The connection into the drive is not the same as USB 2.0, but the connector into the computer is compatible with USB 2.0, while retaining its own special attributes. Sometimes these ports are found both on the front and the rear of your computer. Usually it is OK to connect the drive either to the front or to the rear, though if trouble occurs, it is best to connect it to the port on the rear.
