You don’t need one or the other, as there are larger SSDs you can buy for a premium price. External SSDs tend to be more expensive than their HDD counterparts and often have less storage capacity.

Two main factors play a role in how fast your drive can operate: The underlying storage technology and the connector it uses.Īlthough some drives are faster than others, in general, SSDs can process data faster than HDDs. If you transfer files back and forth to an enormous drive regularly, you don’t want to wait forever for the transfer to complete. Transfer speed is incredibly important, too. The biggest external hard drives aren't always the best drives you can buy. For external drives, you'll get the fastest and more durable drive out of an SSD, like the excellent Samsung T5. HDDs are cheaper, but also larger, slower, and more easily damaged. SSDs are significantly faster than HDDs in many instances, but they get very expensive. They have no moving parts, hence the name. SSDs (solid-state drives) use tiny gate transistors in cells that can flip on or off based on electric pulses. Read/write heads change this data as necessary, so you hear their iconic spinning sounds. HDDs (hard drive disk) use spinning magnetic disks to store data. They both do things quite differently, but at the core of it, SSDs are faster than HDDs. HDDĮxternal drives are served up in two flavors: HDDs and SSDs. It's more NAS than external hard drive, but with 10s of terabytes of storage space, it's all the space you'll need for just about anything. If you need the ultimate in capacity, then look for the Western Digital My Book Duo. It's great for acting as a longer-term backup for your photos and videos, or transferring thousands of them from device to device. If you need something with a few terabytes of space but aren't too concerned about speed, then Western Digital's My Passport Ultra is a great drive with decent performance and multiple terabyte capacities. They're just $25 and give you 64GB of storage, which is enough to easily transfer thousands of photos or a few hundred videos between devices. If you want a device that’s good for transferring documents, photos, or other media from one device to the other, or just want a few tens of gigabytes of space to transfer files from system to system, a USB flash drive like the Corsair Survivor Stealth, might be a good idea. What size of external drive is best? That depends on you. You also don’t want to pay through the nose for a drive you’ll never even come close to filling. It does no good to buy a high-speed device with encryption and remote access if it’s not big enough to store all your data.
