5 Best Extrernal Drives for Backup, Storage and protability in 2021-Review

Anyone who uses a PC should have an external drive. It can back up your precious data or store your overflow, and it can transport or transfer files between computing devices. Xbox One X users, especially, would be wise to invest in an external drive to augment the console’s measly 1TB hard drive (the external drive needs to be USB 3.0-compatible and will be formatted when you insert the drive).

Two things are for sure: No one ever said they wanted less storage space, and no one ever said they wanted a slower drive. Our latest picks for best external performance drive (SanDisk’s Extreme Pro Portable and Samsung’s T7) are blazing-fast—great news if you’re transferring large amounts of data. We’ll also walk you through our other top picks, and everything you need to know to select the best external drive for your needs.

Our latest review explores why anyone would want to purchase a 3.5-inch external hard drive such as Seagate’s Backup Plus Hub.

Best budget external drive

Crucial X6 Portable SSD

The Crucial X6 Portable SSD is square to be hip. Or placed in your hip pocket, at any rate. In a sea of portable SSDs whose shape makes them a literal pain when pocketed, the thin, rounded-edge X6 is a sigh of relief. It’s not state-of-the-art fast, but it’s fast enough for most users and extremely affordable.

Seagate Backup Plus Portable

Check Price on Amazon

Product description

Our runner-up for this popular category is Seagate’s Backup Plus Portable. Like the WD above, it’s a USB 3.1 Gen 1 (5Gbps) drive—plenty enough bandwidth for the hard drive inside. Capacity tops out at 5TB, but the drive is also available in 1TB, 2TB, and 4TB capacities.

In our tests of the 4TB version, we found the Seagate to be slightly faster than the WD with large file transfers (think movies), but slower with small file transfers (think Office documents). It’s still a worthy runner-up, though.

  • This portable hard drive features a minimalist metal enclosure, and is a stylish USB drive

Best performance USB drive

SanDisk Extreme Pro Portable SSD

Check Price on Amazon

Product description

This is the one: SanDisk’s Extreme Pro Portable SSD (1TB) is the fastest USB 3.1 Gen 2 (10Gbps) external SSD we’ve tested to date. Burst performance is roughly on a par with the runner-up Samsung T7, but it blows its competitor out of the water during long writes.

SanDisk’s drive lacks the T7’s handy (and fun) fingerprint security, but it’s about the same price and offers software-based password protection if security is a concern.

  • Designed to work with Windows or Mac computers, this external hard drive makes backup a snap just drag and drop

Best portable Thunderbolt 3 drive

Samsung Portable SSD X5

Check Price on Amazon

Product description

If you have Thunderbolt 3 or 4 on your system, you owe it to yourself to check out a portable Thunderbolt 3 drive such as Samsung’s Portable SSD X5. As an NVMe SSD using PCIe over a cable (that’s basically what Thunderbolt 3 is), it’s stupidly fast—over 2.5GBps reading and writing.

The only reason we don’t universally recommend the Portable SSD X5 is the relative rarity of Thunderbolt 3/4 ports on PCs. The advent of USB4 should alleviate this, but only if vendors decide to combine it with the superset technology that is Thunderbolt 4. Or you may simply soon see USB4 drives with the same 40Gbps transfer rates

About this item

  • THUNDERBOLT 3 AND NVMe POWER: First ever NVMe-based portable SSD from Samsung featuring Thunderbolt 3 technology, the X5 delivers up to 40Gb/s data transfer speeds
  • LIGHTNING FAST READ WRITE SPEEDS: Sequential read and write performance levels of up to 2,800MB/s and 2,300MB/s, respectively
  • DURABLE DESIGN: Full metal body with glossy top and non-slip bottom mat withstands drops of up to 2 meters; Shock resistant internal design features Dynamic Thermal Guard technology to help maintain optimal performance and temperature

Capacity and price

For most consumers, the main shopping concerns for external storage are capacity and price. However, while you might think that the lowest-cost drive provides the most value, it often doesn’t. In fact, dollar for dollar, cheaper low-capacity drives are most often the worst deal.

For example, we compared prices of the WD My Passport portable drive in its 1TB, 2TB, 4TB, and 5TB capacities. Keep in mind, this is one drive on one day (May 13, 2021), and just one vendor, Amazon, but it illustrates the point.

A second drive as backup?

In backup, there’s a fundamental maxim appropriately named the Rule of Three. It states that you should always maintain three copies of your irreplaceable data: the original data, a backup, and a backup of the backup. Preferably, the two backups are kept in separate locations, one being offsite

Keeping a copy online is great for smaller amounts of data and certainly meets the offsite criteria. However, for vast photo, audio, and/or video collections,external drives in pairs (or more), are a faster, more practical solution.

Create complete backups alternately to the two drives every few months. True patrons of wisdom might even take the second drive to work, so there’s no chance of losing both drives to the same local disaster.

Interface

The vast majority of external drives today are USB drives. Beyond that simple  statement, the story gets confusing—largely because of the plethora of variations: USB 3.0, USB 3.1 Gen 1 (5Gbps, which is basically USB 3.0), USB 3.1 Gen 2 (10Gbps), and USB 3.1 Gen 2×2 (20Gbps), and now USB 3.2 and USB4. In an attempt to simplify things, the USB Forum has recently changed the nomenclature to indicate throughput speed–Superspeed USB 5Gbps, Superspeed USB 10Gbps, and Superspeed USB 20Gbps–because performance is a priority for most uses. For the sake of brevity (and sanity), we generally shorten those names to USB 10Gbps, or 10Gbps USB, for instance.

No hard drive, unless combined in RAID with others, can outstrip the 5Gbps (roughly 500MBps real world after overhead) throughput of USB 3.1 Gen 1. Don’t worry about Gen 2, 10Gbps, or Thunderbolt with single hard drive enclosures.

CONCLUSION

Our latest review explores why anyone would want to purchase a 3.5-inch external hard drive such as Seagate’s Backup Plus Hub. Yes, it’s a big unit, but the upsides are significant: nearly three times the capacity and faster sustained throughput than 2.5-inch models. Worth a look,
