WD B079TZ5T1G Review UK (2026) - The Honest Verdict

One dead hard drive is all it takes to rethink how seriously you treat backup. Suddenly, the spec sheet stops being background noise and starts being the only thing that matters. Capacity, build quality, warranty length, and whether the thing will actually survive being shoved in a rucksack three times a week, these are the questions that count. The WD My Passport 2 TB (ASIN: WD B079TZ5T1G) in red is WD's answer to the portable backup problem, and for a lot of people, it's a genuinely sensible one.

Here's the short version: this is a 2 TB portable hard drive aimed squarely at people who want a dead-simple way to back up a PC, an Xbox One, or a PlayStation 4, without spending a fortune or fiddling with settings. It's not fast by modern standards. It's an HDD, not an SSD, so if you're expecting NVMe-class speed, you're in completely the wrong aisle. But for backup, file archiving, and offloading game libraries from a console, raw speed isn't really the point. The point is reliability, capacity per pound, and whether it works without drama. On those fronts, the My Passport largely delivers, and 3,754 owners averaging 4.6 stars suggests most people who buy it agree.

The drive ships formatted as NTFS for Windows out of the box, which means it works with PC and Xbox One immediately. PlayStation 4 requires reformatting to exFAT or FAT32 before use, which is a five-minute job and well documented in the WD support pages. WD bundles its own WD Backup software for automated PC backups, plus WD Security for password protection with hardware encryption, and WD Drive Utilities for drive health checks. Whether you use any of that software is up to you, but it's there, and owners generally report it works without fuss.

Power comes entirely from the USB connection, so there's no separate power brick to carry. The cable is included. The enclosure itself is bus-powered and compact enough to slip into a jacket pocket, which is genuinely useful if you're the kind of person who moves between a home setup and an office or a mate's house. The red colour is the distinguishing feature of this particular variant. WD offers the My Passport range in several colours, and the underlying hardware is identical across them.

The physical size is genuinely portable. It's smaller than a paperback, lighter than your phone charger, and requires no external power. That last point is underrated. If you've ever tried to use a desktop-style portable drive in a hotel room or at a desk without a spare socket, you'll appreciate a bus-powered drive immediately. The USB cable is captive on some variants and detachable on others, so worth checking the listing, but owners consistently report the build quality feels solid enough for regular travel use without being precious about it.

One thing to be clear about: this is a 2.5-inch HDD, not an M.2 drive, not an NVMe device, and not an SSD. There's no PCIe lane here, no NVMe protocol, no DRAM cache discussion to be had. Those concepts simply don't apply. If you came here from an SSD search, this probably isn't what you need. But if you want a portable drive to plug into a laptop, a console, or a desktop for backup and storage expansion, the form factor is exactly right. It just works.

Owner reports are broadly positive about day-to-day use. The drive shows up immediately when plugged in, transfers proceed without interruption, and the WD Backup software runs scheduled backups without needing you to babysit it. A handful of owners report the occasional disconnect on older USB 2.0 ports, which is expected behaviour since the drive draws more power than USB 2.0 can reliably supply. On USB 3.0 ports, which any PC or laptop made in the last decade has, there are no such issues reported with any frequency.

For console use, specifically Xbox One, this is plug-and-play for game storage expansion. The Xbox One's internal drive is notoriously small, and offloading games to an external drive is one of the first things most owners do. The My Passport handles that well. Load times from an external HDD are slightly slower than from the internal drive, but the difference in practice is modest, usually a few extra seconds on game loads, which most owners consider a fair trade for having 2 TB of extra space. PlayStation 4 use requires reformatting, but after that it works identically.

That consistency is actually one of the underappreciated advantages of HDDs for bulk sequential transfers. An SSD with an SLC cache will be dramatically faster for the first few gigabytes, then slow down noticeably once the cache fills, especially on cheaper QLC-based drives. The My Passport won't win any speed contests, but it won't surprise you with a sudden slowdown halfway through copying your photo library either. The speed is what it is, all the way through. Owners copying large video projects or photo archives to the drive report exactly this: steady, predictable transfer rates.

Random I/O is a different story, and it's worth being honest about it. HDDs are genuinely poor at random read and write operations compared to any SSD. The mechanical seek time of a spinning platter drive is measured in milliseconds, while an SSD's random access is measured in microseconds. If you're using this drive for anything that involves lots of small random reads, like running applications directly from it, or using it as a scratch disk for editing software, you'll find it frustratingly slow. That's not a flaw in this particular drive, it's the nature of HDD technology. Use it for what it's designed for and you'll have no complaints.

What the My Passport does have is a USB bridge controller that converts the internal SATA connection of the HDD to USB 3.0 for the external connection. WD doesn't publish which specific bridge chip they use, which is standard practice for portable drive enclosures. In practice, the bridge controller is not a meaningful differentiator for this type of product. The bottleneck is always the spinning platters, not the bridge.

The internal drive is almost certainly a WD Blue or WD-branded 5,400 RPM 2.5-inch HDD, which is the standard configuration for the My Passport range. WD has been making these drives for long enough that the mechanical design is well understood and the failure rates are well documented in the industry. The 5,400 RPM spin speed is quieter and more power-efficient than 7,200 RPM alternatives, at the cost of some sequential speed. For a portable drive that you want to run quietly and not drain your laptop battery, that's the right trade-off.

Owner reliability reports across 3,755 averaging 4.6 stars tell a reassuring story. The majority of owners report years of trouble-free use. There are negative reviews, as there always are with any mechanical drive, because HDDs do fail. They're mechanical devices with moving parts. The question is whether the failure rate is higher than expected, and from the review pattern here, it doesn't appear to be. The negative reviews cluster around a small number of units that arrived dead or failed early, which is consistent with the industry-average infant mortality rate for HDDs rather than a systematic quality problem.

One thing worth saying directly: no portable HDD, regardless of brand, should be your only copy of important data. The My Passport is a backup drive, and it should be part of a backup strategy, not the entirety of one. The 3-2-1 rule (three copies, two different media types, one offsite) exists precisely because drives fail. Use this to back up your PC, but keep your originals somewhere else too. WD's own bundled backup software will help you automate that process, which is genuinely useful if you're not the type to remember to plug in a drive and copy files manually.

Owner reports don't flag heat as an issue. The enclosure is plastic, which doesn't dissipate heat as efficiently as aluminium, but the drive's power consumption is low enough that this isn't a practical problem. You're not going to thermally throttle a 5,400 RPM HDD doing file copies over USB 3.0. The drive may feel slightly warm to the touch after a long transfer session, but that's within normal operating parameters for this type of device.

One thermal-adjacent consideration: don't leave the drive in direct sunlight or in a hot car. This applies to all HDDs, and indeed most electronics. The magnetic platters and read/write heads are sensitive to extreme temperatures. Under normal indoor use, including extended backup sessions, the My Passport's thermals are a non-issue. No heatsink is needed, no active cooling, no thermal paste. It just runs.

Price per gigabyte for portable HDDs is still significantly better than portable SSDs at this capacity. You're paying a fraction of what a 2 TB portable SSD costs, for a drive that, for backup purposes, does the same job. The speed difference is real but irrelevant if you're setting up an overnight backup and not sitting there watching a progress bar. If you need speed, buy a portable SSD. If you need capacity per pound for backup and archiving, a portable HDD like this makes more financial sense.

The 1 TB version is cheaper but halves your headroom, and given how quickly game installs and photo libraries grow, the extra capacity of the 2 TB version is usually worth the modest price difference. The 4 TB and 5 TB versions cost more but offer better price per gigabyte at those capacities, which is worth considering if you know you'll need the space. For most buyers, the 2 TB hits the right balance of capacity, price, and portability.

Xbox One compatibility is immediate out of the box. The drive ships formatted as NTFS, which is what the Xbox One requires for external game storage. Plug it in, follow the Xbox's on-screen prompts to set it up as extended storage, and you're done. Games can be installed directly to it or moved from the internal drive. PlayStation 4 requires reformatting to exFAT or FAT32 first, which you do through the PS4's storage settings. It takes a few minutes and wipes the drive, so do it before you put anything important on it.

For Mac users, the NTFS formatting means the drive will be read-only by default on macOS without additional software. If you need to write to it from a Mac, you'll need to either reformat to exFAT (which works on both Windows and Mac) or use third-party NTFS drivers. This is a common gotcha with Windows-formatted drives and not specific to WD. Worth knowing before you buy if you're planning to use it across both platforms. WD does offer macOS-specific versions of the My Passport with HFS+ formatting, so check you're buying the right variant for your use case.

Console gamers with a stuffed internal drive will find this particularly useful. The Xbox One's 500 GB or 1 TB internal drive fills up fast with modern game installs, and the My Passport is one of the most popular solutions to that problem. The plug-and-play compatibility, the 2 TB of headroom, and the fact that you can unplug it and take it to a friend's house make it practical in a way that internal upgrades aren't.

Who should look elsewhere? If you need speed, buy a portable SSD. The Samsung T7, the WD My Passport SSD, or the Crucial X6 all offer dramatically faster transfer speeds in a similarly portable form factor, at a higher price per gigabyte. If you're a creative professional who needs to edit video directly from an external drive, an HDD will frustrate you. If you're building a home NAS or need a drive for sustained server-style workloads, look at WD's Red NAS drives instead. And if your priority is absolute maximum capacity for the money, desktop external HDDs offer better price per gigabyte than portable ones, at the cost of needing a power brick.

The Toshiba Canvio Basics 2 TB is the budget option in this space, often available for less than the My Passport. It's a no-frills drive with no bundled software and a more basic enclosure. Transfer speeds are similar. If you genuinely don't want software, don't care about password protection, and just want the cheapest possible 2 TB portable drive, the Canvio Basics is worth a look. But the My Passport's three-year warranty, included encryption software, and generally better build quality perception among owners make it worth the small premium for most people.

Neither competitor offers anything fundamentally different in terms of actual performance, because they're all 5,400 RPM 2.5-inch HDDs connected over USB 3.0. The differentiators are warranty length, bundled software, build quality, and price. On warranty, WD wins. On price, Toshiba often wins. On software bundle, WD wins. On brand trust for long-term reliability, WD and Seagate are broadly equal with decades of track record between them.

The 4.6-star average from nearly 3,800 owners isn't a fluke. It reflects a drive that works as advertised, holds up over time, and doesn't cause headaches. The three-year warranty is the standout advantage over most rivals, and the included WD Security encryption is a nice extra if you're carrying sensitive files around. The red enclosure is a minor but genuine differentiator if aesthetics matter to you, and there's nothing wrong with a drive that looks decent on your desk.

The honest caveat is this: if you need speed, this isn't it. A portable SSD like the Samsung T7 or the WD My Passport SSD will transfer files several times faster. You'll pay more per gigabyte, but for creative work or running applications directly from an external drive, the speed difference is worth the money. The spinning HDD inside this drive is the right tool for backup and archiving, and the wrong tool for anything that demands quick random access.

If budget is the primary concern and you don't care about the software bundle or the extra year of warranty, the Toshiba Canvio Basics 2 TB is cheaper and does the same core job. That's the honest don't-overspend option. But for most people who want a bit more peace of mind and a proper software-backed backup solution, the My Passport earns its price premium over the bare-bones alternatives. Buy it for backup. Keep your originals somewhere else. Job sorted.
