About this deal

The LaCie 2big RAID array promises the reliability and delivers the performance benefit you'd expect from 7,200rpm platters, magnified by the default RAID 0 setting, while the optional RAID 1 setting is available if you want data redundancy. (A JBOD mode is also available if you don't want to use RAID.) Who It's For On the 20TB model in RAID 0, striped mode, you have a capacity of about 18.1TB available to use from the outset.

The quoted transfer speed for the bare mechanisms is 210 MB/s, and in JBOD mode that’s almost exactly what you get. The WD My Passport SSD with USB 3.2 doesn’t look like its travel-enabling namesake, the My Passport Go, but it’s all ready to go places. It’s small (3.9x 2.2x 0.4 inches) and attractive, with its shiny ridged surface and choice of five snazzy colors (blue, gold, gray, red, and silver). In a nutshell, it is a storage device that contains an internal hard drive. The fact that there's two types of hard drives - 2.5-inch and 3.5-inch - means that there are also two types of external hard drives: larger desktop hard drives and smaller portable hard drives. Perhaps the only thing you don't need to pay all that much attention to is the warranty. Sounds counter-intuitive, perhaps? Sure, a long warranty is nice. But if your drive breaks because you dropped it, the warranty likely won't cover that, anyway. 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 broken drive. The real value lies in what's on your drive, not the drive itself. Connection to your computer is via USB Type-C, and cables come for both this standard and to convert a conventional USB 3.0 port to the Type-C variety if you haven’t embraced that newish connector yet.LaCie is a company popular for it’s Thunderbolt storage. No other company has offered as many different models with this technology. The LaCie 5Big comes with a traditional pedestal form factor that can fit nicely under a desk. This hard drive uses Marvell hardware RAID technology, and you can align the disks in RAID 0, 1, 5, 6, 10 arrays or go for a simple JBOD configuration. Moreover, users can also configure more than one array in the system. 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. It is also well suited as long-term multimedia storage hooked up to a PC or large-screen smart TV from Sony or a recent Samsung as well - some smart TVs support NTFS and FAT32 or NTFS and ExFat, very rarely do they support all three file systems.

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.

Western Digital goes big on personal storage

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. How an external drive connects to your PC or Mac is second only to the type of storage mechanism it uses in determining how fast you'll be able to access data. These connection types are ever in flux, but these days, most external hard drives use a flavor of USB, or in rare cases, Thunderbolt.

Details about the extent of our regulation by the Financial Conduct Authority are available from us on request. Do you care more about speed, capacity, or price? If it’s the first, SSDs store data in flash memory rather than on spinning platters the way traditional hard drives do and thus operate a whole lot faster. The interface can also make a difference; Thunderbolt 3 will be a lot faster than USB, for example. To calculate the average price, we add up the cheapest daily prices of the last 90 days and divide by 90.While it’s still a ‘My Book’ product, the new hardware looks much more like what it truly is; a tiny desktop server.

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. A collection of spinning drives configured with a RAID level designed for faster data access can approximate the speeds of a basic SSD, while you should consider a drive with support for RAID levels 1, 5, or 10 if you're storing really important data that you can't afford to lose. Hit the link above for an explanation of the traits and strengths of each RAID level. Some require you to sacrifice raw capacity for data redundancy, so you'll want to pay attention to the nuances of each level. This is a great choice to consider as an external drive for Mac and external hard drives full stops. It works differently than standard external hard drives, and you can plug it straight into the router to get a direct internet connection. You can share files to and from your devices via Wi-Fi, and it also means that you can get your data at any time from anywhere, and you don’t need to leave a specific computer on to access your data. 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. Of these, the WD Drive utilities are the most vital, as they allow you to change the RAID configuration of the Duo.Cloud functionality, which allows individuals and businesses to operate a personal cloud. Essentially your very own cloud storage solution.
