Our take
The Iomega eGo 35684 suits someone looking for a documented portable 1TB hard drive that can connect over USB 3.0 or an older USB 2.0/1.1 host and does not use a separate power adapter. B&H also lists a Drop Guard case and 256-bit hardware encryption, but explicitly limits encryption to PC use. The deciding compromise is age: the exact listing is marked no longer available, its platform requirements are from older Windows and Mac releases, and present software support or a current exact Amazon offer has not been established. Treat it as a configuration to verify with a seller, not as a confirmed current bundle.
A buyer who wants a portable nominal 1TB HDD with a documented USB 2.0 or 3.0 host path and USB power, and can verify the legacy drive's current host support and exact seller offer.
Buyers who need verified current operating-system or encryption-software support, a confirmed current Amazon ASIN, a guaranteed case or cable in the package, a newer capacity than 1TB, or a drive whose individual condition has been checked.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- B&H identifies the exact Ruby Red reference 35684 as a portable 1TB hard drive.
- The exact listing documents USB 3.0 plus backward compatibility with USB 2.0 and 1.1, and describes USB bus power.
- The historical listing names a Drop Guard case and 256-bit hardware encryption with a clear PC-only limit.
What to weigh up
- The exact B&H listing is marked no longer available; no current exact Amazon offer is verified.
- The original OS requirements are dated, and present backup-software or encryption support is not established.
- A current seller's cable, case, bundle, warranty eligibility, and individual drive condition are unknown.

What the features mean for you
Which exact eGo configuration is documented?
The useful identifier is Iomega reference 35684: B&H names it as the eGo Portable 1TB hard drive in Ruby Red. That separates this configuration from the black 35687 sibling and from other eGo capacities. Check the printed reference and color rather than assuming that a listing using only the broad eGo name is the same product. The historical ASIN B0074ND9ZE came from an old source row and has not been verified as a current Amazon offer; the tagged destination is an exact-model search, not a direct product link.
B&H lists dimensions of 4.83 by 3.40 by 0.66 inches and a weight of 6.70 ounces, about 190 grams. Those figures help estimate whether the older enclosure will fit a case or bag, but they do not say anything about the condition of a particular used unit. The page marks this exact listing no longer available, so use it to identify the historical configuration and verify any present seller's model code, color, and included parts.
Is 1TB the right amount of storage?
The advertised capacity is 1TB, which is a useful middle ground between the 160GB and 500GB options in this comparison and the larger 2TB or 3TB HDDs. That capacity may suit a portable archive that has outgrown a small legacy disk, while a collection already above 1TB should be directed to a larger configuration. The label is nominal capacity, not the exact space available after formatting and system overhead.
This is a hard disk drive, not an SSD. The saved source supports the capacity and product type, not a measured transfer result, reliability estimate, or advantage for a particular workload. Keep another copy of important files: one drive's storage capacity does not establish a backup plan or the health of an individual used unit.
How do USB connection and power affect setup?
The exact-model listing describes USB 3.0 and backward compatibility with USB 2.0 and 1.1. That gives the model a documented connection path for an older host, but it cannot prove that a current computer's operating system or drivers will recognize a legacy device. The B&H specifications list Windows XP, Vista, and 7 and Mac OS X 10.5 through 10.7, and say a Mac needs a reformat; those are old requirements, not current compatibility advice. Check the intended computer before moving files.
B&H says the drive is powered through USB, so the documented design does not need a separate power cable. That can simplify a portable setup, but a present listing may not include the original cable and this old page cannot establish that a particular cable or USB port is in good condition. Its advertised USB interface rate is not a measured result for this drive, host, or workload.
Keep the encryption and software claims in their original scope
B&H describes built-in 256-bit hardware encryption and explicitly labels the feature PC-only. That limit matters: the listing does not support a promise of Mac encryption, a current Windows workflow, or compatibility with every later operating system. A buyer relying on encryption should confirm how the drive is unlocked on the exact intended computer and should not put the only copy of important data behind an unverified old utility.
The same page names the Iomega Protection Suite as a download and describes backup and antivirus components. It lists period software and operating-system details, but the source does not establish that the downloads still exist or work now. Treat encryption and software as historical configuration details rather than current benefits until the model, utility, and host support are independently confirmed.
What does the listed Drop Guard case change?
The original B&H package list names an Iomega Drop Guard case, and its description claims protection from drops up to seven feet. That may explain the configuration's portable design, but it is a seller-listed claim rather than a test of this review or of a particular drive. A case does not make the hard disk waterproof, and it cannot establish that an older unit survived an impact.
The historic package list also includes a USB data-and-power cable, software download, quick-start guide, and limited three-year warranty. Those details describe the listing, not a present seller's box. Ask the seller whether the case and cable are included and in usable condition, and check any warranty directly rather than assuming an old warranty transfers to a used drive.
Who should choose it over another legacy drive?
Consider the 35684 when a documented 1TB portable HDD, USB 2.0/1.1 compatibility, and USB-powered setup fit the intended host, and when you are willing to check present support and seller details. Its capacity is larger than the 160GB Seagate Portable and the qualified 250GB UnionSine configuration, while its USB-powered design offers a different setup from the 400GB desktop Pushbutton Backup that uses an adapter. It is not the only way to reach 1TB, and no saved evidence ranks it by speed, price, or reliability.
Pass if the old operating-system requirements cannot be reconciled with your computer, PC-only encryption is unsuitable, you need current software support, or a seller cannot confirm the exact 35684 variant and working condition. Use the tagged search to inspect each actual offer; do not assume the historic Amazon ASIN or the old Drop Guard package describes what is available today.
What else to compare
Before you buy
Does reference 35684 work with USB 2.0?
The saved exact-model listing says it is backward compatible with USB 2.0 and 1.1. That describes the interface path; it does not establish support on a particular current computer or operating system.
Can I use the hardware encryption feature on a Mac?
B&H explicitly marks the 256-bit hardware-encryption feature PC-only. Do not assume Mac support or current companion-software support.
Will a present used offer include the Drop Guard case and cable?
The old B&H package list names both, but a present seller's contents and their condition must be confirmed directly.
Is B0074ND9ZE a confirmed current Amazon listing for 35684?
No. It is the historical source-row ASIN only. Use the tagged exact-model search and verify the reference, color, capacity, seller, and package.
Where can I check the current price?
Use the Amazon link for current offers. Check the exact model, seller, product condition, delivery, and return terms. This page does not display a live price or confirm stock.

The decision
The Iomega eGo 35684 suits someone looking for a documented portable 1TB hard drive that can connect over USB 3.0 or an older USB 2.0/1.1 host and does not use a separate power adapter. B&H also lists a Drop Guard case and 256-bit hardware encryption, but explicitly limits encryption to PC use. The deciding compromise is age: the exact listing is marked no longer available, its platform requirements are from older Windows and Mac releases, and present software support or a current exact Amazon offer has not been established. Treat it as a configuration to verify with a seller, not as a confirmed current bundle.
