Our take
A working 1TB portable HDD identity with USB 3.0 and USB 2.0 host compatibility, provided the exact model is confirmed.
A legacy 1TB portable-drive option for someone who can confirm model HD1027B3 and provide a current backup method, while leaving power and seller contents open for verification.
Buyers who require a verified current Amazon offer, current backup-software support, confirmed bus power, FireWire, Thunderbolt, console compatibility, or a measured performance claim.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Newegg's exact model page identifies HD1027B3 as a black 1TB Clickfree C2 portable 2.5-inch drive.
- The listing and product sheet document USB 3.0 and USB 2.0 compatibility.
- The product sheet separates the black portable 1TB SKU from the C2 desktop variants, giving a buyer a specific configuration to verify.
What to weigh up
- HD1027B3 is not proven to crosswalk exactly to product-sheet SKU 1027B3-1004-100 or historical Amazon ASIN B007JZKSH4.
- Automatic backup, restore and migration are old product-era features; current software and operating-system support are unknown.
- The portable power arrangement, current seller cable/package, unit condition, warranty eligibility and measured performance are not established.

What the features mean for you
Will nominal 1TB fit the files you plan to carry?
Newegg's exact-model listing names a 1TB Clickfree C2 portable drive, model HD1027B3, in a black 2.5-inch configuration. Nominal 1TB can suit an archive of documents, selected photos, or a portable copy of files that also exist elsewhere. Formatted free space will be lower, and the saved evidence says nothing about the health or contents of a particular used unit. Capacity alone does not make it a safe single copy of important files; keep a separate backup if the data matters. This is a defined capacity option, not evidence that it costs less or transfers files faster than another model. ([Newegg exact-model listing](https://www.newegg.com/black-clickfree-c2-1tb/p/N82E16822688062), title and model/specification table, checked 2026-10-11.)
What does USB 3.0 with USB 2.0 compatibility mean here?
The Newegg listing and Clickfree sheet identify USB 3.0 and say the C2 is compatible with USB 2.0. That provides a documented host path for an older USB 2.0 computer as well as a USB 3.0 port. The interface generation does not give a measured copy time for a particular drive, cable, computer, or workload, and no saved test establishes performance. These sources do not document FireWire, Thunderbolt, or console preparation. If a legacy host or application is essential, verify the connector and the exact physical unit before relying on an old drive. ([Newegg exact-model listing](https://www.newegg.com/black-clickfree-c2-1tb/p/N82E16822688062), lines 111–117 and 120–148; [Clickfree C2 product sheet](https://media.dustin.eu/media/d200001003268063/clickfree-c2-1tb-35-backup-desktop-usb-30-document.pdf), page 1, lines 13–18 and 83–87, checked 2026-10-11.)
Can you count on the automatic-backup software today?
The listing and product sheet describe automatic backup, restore, migration, media viewing, and related software features. They explain how Clickfree positioned the C2 when it was sold, but the sheet is marked ©2010 and gives period system requirements such as Windows XP, Vista, Windows 7, and Mac OS X 10.5 or later. Those historical details do not show that the software installs, runs, or receives support on a current computer. Consider the C2 for its documented storage hardware only if you already have a supported backup method or can verify one separately. Current updates, security behavior, cloud services, and present operating-system support are not established. ([Newegg exact-model listing](https://www.newegg.com/black-clickfree-c2-1tb/p/N82E16822688062), lines 111–117; [Clickfree C2 product sheet](https://media.dustin.eu/media/d200001003268063/clickfree-c2-1tb-35-backup-desktop-usb-30-document.pdf), page 1, lines 2–5 and 21–24, checked 2026-10-11.)
Do the model and retail SKU identify the same configuration?
Newegg's exact listing uses HD1027B3 for the black C2 1TB portable drive. The Clickfree sheet separately gives the portable black 1TB SKU as 1027B3-1004-100 and lists a different 1TB desktop SKU. Their shared `1027B3` text is suggestive but does not prove an exact retail-code crosswalk. The frozen Amazon row carries ASIN B007JZKSH4, which is not confirmed as a current offer for either code. Check the exact model and 1TB portable description on the seller page or unit label; do not rely on the historical ASIN alone. The sheet lists portable dimensions of 8 × 12.2 × 1.2 cm, which describe the old product configuration rather than the condition or package of a present unit. ([Newegg exact-model listing](https://www.newegg.com/black-clickfree-c2-1tb/p/N82E16822688062), lines 85–92 and 120–148; [Clickfree C2 product sheet](https://media.dustin.eu/media/d200001003268063/clickfree-c2-1tb-35-backup-desktop-usb-30-document.pdf), page 1, lines 63–75, checked 2026-10-11.)
Is it documented to work away from a wall outlet?
The Clickfree sheet lists an 80 cm USB cable in the period box contents and says the power adapter is for the desktop model only. That distinction helps separate the portable C2 from the desktop version, but it does not explicitly state that this portable configuration is bus-powered. Do not treat `portable` or the desktop-only adapter note as proof that a specific unit can run from a laptop without another source of power. Keep the power arrangement unknown in a no-outlet shortlist and check the exact unit's documentation and cable before relying on it. The saved sources also do not verify what a current seller includes. ([Clickfree C2 product sheet](https://media.dustin.eu/media/d200001003268063/clickfree-c2-1tb-35-backup-desktop-usb-30-document.pdf), page 1, lines 25–29 and 63–75, checked 2026-10-11.)
Where does it fit beside another 1TB portable HDD?
The Toshiba Canvio Premium HDTW110XC3A1 is another 1TB portable HDD with documented USB 3.0 and USB 2.0 host use, and its exact-code listing also documents USB power. The Clickfree sources support USB 3.0/2.0 host use but leave portable power unknown, so it should not outrank a product with established bus power when working without an outlet is required. For a desk or archive where power setup is open, it remains a possible capacity-and-interface match if the seller confirms HD1027B3. Clickfree's original automatic-backup features are a historical distinction only; current support is unknown. Neither model's saved evidence proves the historical Amazon ASIN is today's exact offer.

What else to compare
Before you buy
Will it work with a USB 2.0 port?
The exact-model listing and product sheet state USB 2.0 compatibility alongside USB 3.0. Confirm the connector and cable on the actual unit if this is essential.
Can I rely on its automatic-backup software today?
Current support is not established. The saved feature descriptions and operating-system requirements are product-era material; verify current software separately or use a supported backup method.
Is the portable C2 definitely USB-powered?
That is unknown. The sheet says the adapter is for the desktop version, but it does not explicitly confirm portable bus power.
Does historical ASIN B007JZKSH4 identify this model today?
No current exact-offer crosswalk is verified. Use the tagged HD1027B3 model search and check the seller's exact model, capacity, and portable configuration.
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.
