External Backup Storage Under $2500: Desktop, Portable, RAID, NAS, WI-FI & Cloud
There have been some very interesting developments in external storage solutions for home/studio and on-the-go. We can go wired or wireless (network or Wi-Fi), desktop or portable, (spinning-platter-based) hard disk or solid-state drive or a mix of the two in a multi-disk array. While the vast majority of new drives are USB 3.0 (often accompanied by FireWire connectivity), we’re seeing a marked increase in the number of drives supporting Thunderbolt connectivity, which is now finding its way to Windows machines as well as Mac. Drives that support the cloud are mushrooming, thereby facilitating remote access from anywhere in the world, even from mobile iOS and Android devices. All in all, it’s a dizzying array of choices—and all initially under $2500. (The number, capacity, and type of drives that may be added to or substituted in some enclosures may add to the cost.)
Choosing The Drive That’s Right For You
Because many of today’s external storage devices can no longer be simply pigeonholed into one category, I have opted to list them under the brand name, instead of under categories, but have added identifiers in brackets after each listing.
This will be your key in the product roundup that follows: HDD (Hard Disk Drive); SSD (Solid-State Drive); HDD/SSD (where you have a choice or can mix the two inside one enclosure, as in some RAID drives, either purchasing the enclosure thusly configured or where you have to buy and install the drives on your own); P (Portable—bus powered, battery powered, or, in rare cases, mains powered but still designed for mobile use); RAID (normally user-configurable, but usually RAID 1 or RAID 0 out of the box for a two-disk enclosure); NAS (Network-Attached Storage—for all practical purposes, with cloud functionality); Wi-Fi (wireless Wi-Fi connectivity); MC (Memory Card compatible).
I should also point out that with regard to enclosures, the manufacturer may specify which drives (by type and/or manufacturer) are authorized/warranted for use—so don’t buy an enclosure simply because you have some spare drives lying around.
Note: The products listed below are the latest available from the various manufacturers. These companies may also offer other storage products that fit various other categories, so please check their websites, supplied at the end of this article, for the complete lineup of products.

Today’s hardwire-connected drives are largely USB 3.0 (backward compatible with USB 2.0). Many drives continue to support FireWire 400 and/or 800, with a few also supporting eSATA. And there are an increasing number of Thunderbolt drives, which are also compatible with Windows machines equipped to handle them, not just Mac.
Given a choice, USB 3.0 beats out FireWire in speed and supports connection to a multi-device hub—but it tends to be finicky. Thunderbolt and FireWire, however, support daisy-chaining—that is, connecting a limited number of drives in series. While it certainly delivers on speed, eSATA support for sleep mode is in question, which may be a consideration. As for speed, Thunderbolt now takes a substantial lead above the rest. My reticence to invest in Thunderbolt is that it may be headed down the same road as FireWire, only to be replaced by a newer technology.
In contrast, USB, for all its failings, appears to be here for the long haul and, in one form or another, is found on practically every consumer device we use—even to the point of charging many of our devices. Add to that the expected and doubly fast USB 3.1 implementation in the coming months, with a smaller plug that will require an adapter to be backward compatible with USB 3.0 and 2.0, according to Internet sources. Then again, Thunderbolt 2 is beginning to appear, seriously topping all speeds.
On the flip side are wireless devices: NAS (Network-Attached Storage), Wi-Fi, and, by extension, what have come to be known as “cloud” drives. Wireless drives relieve your desktop of clutter and may provide access to your data from virtually anywhere. They can be used for backups as well as primary storage. Of course, for any of this to work, your computer must be properly equipped. Don’t run out to buy a USB 3.1 drive, for example, if your computer only supports USB 3.0—the drive will work, but only at USB 3.0 speeds. For each port that you plan to use on the drive, there has to be a supporting port on the computer.
Cloud Service VS. Cloud Drive
The “cloud” is nebulous by definition, and has largely become a consumer catchphrase. Any way you look at it, it’s a way to store and access data without being directly connected to it, often from a remote location, and hopefully securely. Its primary uses are sharing and backing up data—much of it images and streaming multimedia content (many cloud drives emphasize the streaming aspect).
When it comes to storing and backing up image files, one option is to utilize a cloud service. However, consider this: (1) free storage space is limited—typically only a few gigabytes, limiting you to JPEGs (and small movie files), along with more conventional data; (2) increasing storage capacity involves a monthly or yearly fee but may then allow you to store anything and everything, up to a defined limit (you might still not be able to back up your entire image library); (3) connection problems or a problem with your account might retard or block access; (4) security is a potential issue; (5) as we’ve seen in the past, services close down and all your data is forever lost to the ether. That doesn’t mean you should not avail yourself of the service, especially if it’s free. It does add a level of insurance in case something untoward happens to your home/studio storage system. And there are certainly services that have found ways around these limitations, in some fashion and to some degree.
The next option—your own cloud drive (usually NAS—Network-Attached Storage)—will cost more initially, but pays for itself over time. You own it, you control it, you always have access to it—from practically any device, and from anywhere in the world. Unlike a cloud service, you can store terabytes on top of terabytes of data, limited only by the capacity of the drive or expansion drives connected via USB port, for instance. It becomes immediately available to you, and to those you authorize to access it, often with built-in security.
What’s A Raid Drive?
You can think of a RAID drive as perhaps the ultimate means for backup storage. These drives can be used as working drives, but they have built-in backup functionality that you should exploit to the fullest.
A RAID (Redundant Array of Independent Disks) enclosure houses two or more disk drives (hard disk or solid-state) with cost reflected in the size and level of redundancy, and type of disk. RAID drives are usually supplied with the required disks, although some are sold as diskless enclosures to which hard disk or solid-state drives are independently added—but all come with built-in monitoring and controllers to oversee operations.
Depending on the device, you can change the RAID mode on the drive itself or with a software utility (rarely is this a fixed state). Dual-disk configurations are generally sold as RAID 0, for improved performance, or RAID 1, for improved security. RAID 1 should be your first choice for valuable data because each disk mirrors the other, thereby functioning as an ongoing backup.
Because RAID 1 drives mirror each other, that effectively cuts total storage in half, so that a 2TB drive becomes a 1TB drive. RAID 0 allows you to maximize the full capacity of that drive, so that 2TB remains 2TB (minus space lost to system files in each case). Cost, total capacity, backup proficiency, and efficiency increase with an increasing number of disks inside the enclosure.
