Generally, the higher a drive's capacity, the cheaper it will be per gigabyte. But that's not always true; sometimes the very highest-capacity drives come at a per-gigabyte price premium. The basement for budget external SSDs is currently about 7 cents per gigabyte, mostly from second- or third-tier vendors. Calculate your bottom-line price when comparing a host of drives. Also, just because you put a PCIe NVMe drive in an enclosure doesn't mean you should magically expect it to go any faster than a standard external SSD. Any drive placed in an enclosure is still subject to the peak USB speed supported by the enclosure's own electronics and controller, and by the USB protocol supported by the port you plug it into. The Samsung Portable SSD T9 is a high-performance external SSD, coming in capacities of up to 4TB and with an interface that supports USB 3.2 Gen 2x2, which is blazing fast if you have a computer with a port that supports this standard (you can add a 2x2 expansion card to a desktop if need be). It was fast on our Windows testbed, which has a 2x2 expansion card, and surprisingly fast when tested on an Apple MacBook Pro with a Thunderbolt 3/USB 3.1 Gen 2 port. AES 256-bit hardware-based encryption, the gold standard in civilian encryption solutions, and an upgraded Samsung Magician software suite sweeten the pot. Who It’s For Need to expand the local storage on your PC or Mac for music and movies, or all the pics and videos you collect from your phone? The traditional answer has been an external hard drive. The newer, better answer is a portable solid-state drive (SSD).

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. This is also where a spec known as the "terabytes written" rating (or TBW) comes in. It refers to how much data can be written to a drive over its life before some cells on that drive begin to fail. The entire drive itself won't stop functioning, but rather, less and less storage will be made available as time goes on. Our typical benchmark-test results for even run-of-the-mill external SSDs show speeds in excess of 400MBps. Practically speaking, this means you can move gigabytes of data (say, a 4GB feature film, or a year's worth of family photos) to your external SSD in seconds rather than the minutes it would take with an external hard drive. COST PER GIGABYTE. The way to calculate relative value on drives like these is to perform some simple math and figure the cost per gigabyte based on the price of a given drive on the day you're shopping. Because SSD pricing fluctuates all the time, relative value does, too.CARRY WEIGHT. Most SSDs weigh a negligible couple of ounces. The carabiner retention loop of SanDisk's Extreme family of external SSDs is especially handy, because many SSDs are small and light enough that losing them is an easy and expensive mistake. A tiny yet highly capable external SSD, the Crucial X9 Pro scored well in our benchmarks and comes in capacities up to 4TB. Its interface supports the USB 3.2 Gen 2 standard, which affords near-universal compatibility if your computer has a USB port (although you’ll need an adapter to connect to a USB-A port). The X9 Pro’s basic ruggedization features and 256-bit AES encryption protect it from tumbles as well as both meteorological and human threats while you’re traveling. Who It’s For RAID (redundant array of inexpensive drives) which is a smart way of either improving your drive speed - at the cost of reliability - or improving reliability - at the cost of capacity. 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.

SEAGATE Expansion Desktop External Hard Drive - 10 TB, Black

Desktop hard drives are cheaper per Terabyte, offer capacities above 20TB, usually perform better but they are much larger and require an external power supply unit.

Is an External SSD Faster Than an External Hard Drive?

Yes: Again, hard drives are slower because they have to physically rotate disks and move a reader arm to access your data. Just how much faster is it to read data from flash cells than from particular points on spinning platters? Typical throughput for consumer hard drives is in the range of 100MBps to 200MBps, while SSDs that support Thunderbolt 3 or 4, or USB 3.2 Gen 2x2, can have read and write speeds pushing 2,000MBps or even higher. (One factor in hard drive speed is spin rate—among external drives, 5,400rpm units are more common and more affordable than 7,200rpm.) Perhaps the only thing you don't need to weigh too heavily is the warranty. If your drive breaks because you damaged it, the warranty likely won't cover it. 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 device. A long warranty is well and good, but the real value in a drive usually lies in what you have on it. In addition to 640MBps, you'll also see USB 3.0's theoretical data rate described as 5Gbps. (That's gigabits, not gigabytes, per second.) You also may see this interface dubbed "USB 3.1 Gen 1" or "SuperSpeed USB 5Gbps" (in practice, all three are the same thing), to differentiate it from "USB 3.1 Gen 2" or "SuperSpeed USB 10Gbps," which raises the ceiling to (you guessed it!) 10Gbps. USB 3.1 Gen 2 is the latest version widely available in consumer external SSDs at this writing. PCIe external SSDs can take advantage of the extra 5Gbps of bandwidth, but you need to have a USB port that supports the spec to see the extra speed benefit. (And yes, we are talking about "USB 3.1" as opposed to "USB 3.2." Bear with us.)

10TB External hard drives | Argos

External hard drives come in various storage space amounts any from 1 terabyte all the way up to 24 terabytes and almost everything between. What does an external hard drive do?The LaCie isn't cheap; its price per gigabyte is easily beaten by more general-purpose portable SSDs and even rugged rivals like the ADATA SE800 (though the latter's USB port must be covered before taking a dip). But it's tailor-made for Apple content creators. As you can see, some USB specs are tied to certain system-side physical USB connectors. We'll get into that in a moment. What sets this drive apart aside from the gaming aesthetics is its total compatibility. Since it comes pre-formatted with the ExFAT file system in addition to being compatible with PCs and Macs it's plug-and-play compatible with the Sony PlayStation 4, PS5 and the Microsoft Xbox One. RUGGEDIZATION. The degree of ruggedness does vary from drive to drive, with drives like the ADATA SE800 leading the field at the moment among mainstream-price external SSDs. IP68 certification is a good spec to look for if you're serious about waterproof and dustproof drives. Also: Don't confuse the system-side interface with the connector that joins the cable to the drive itself. On most newer portable SSDs, the connector at the SSD end is a USB Type-C port (the same as the kind you might find system-side)...

The Crucial X9 Pro is a competitively priced, highly portable external SSD that should appeal to most anyone. The X9 Pro is great for travelers, or indeed anyone who wants a fast, reasonably rugged and secure portable SSD. It's not like most external SSDs need to be carried in both hands or a briefcase, but Kingston's XS2000 is positively tiny—0.5 by 1.3 by 2.7 inches and about an ounce, barely bigger than most USB flash drives yet offering up to 2TB of storage. It's also tough enough to earn an IP55 ingress protection rating against sand, dirt, or rain, though it shouldn't be immersed in water, and its USB-C 3.2 Gen 2x2 interface makes it faster than the average SSD. It's unlikely that your PC has a port that actually supports the Kingston's peak speed, however. Who It's For 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. On others, though, the connector might be a Micro-USB Type-B, which is a flat, wide connector that is different from any USB port you'll see on a laptop or desktop. An external hard drive is basically a drive that provides storage space. While a computer’s internal hard drive delivers storage within the computer, an external hard drive is portable and comes in various amounts of storage space. How much does an external hard drive cost?Arguably more important than the type of storage mechanism inside an external SSD is how it connects to your PC or Mac. Almost all external SSDs today plug into either some flavor of USB port, or a Thunderbolt 3 or 4 port.
