Our take
Choose the Canvio Slim II when a slim silver 1TB portable HDD and a documented USB 3.0 connection with a USB 2.0 fallback fit the host and archive size. Its useful distinction is the combination of a brushed-aluminum enclosure and low listed weight with more capacity than a small legacy archive drive. The important caveats are equally practical: the B&H page says its offer is no longer available, the source does not establish bus power, and the historical Amazon ASIN does not prove a current exact listing. Confirm the full model and seller's power and cable details before relying on it.
A buyer who needs a slim nominal 1TB archive and has a documented USB 2.0 or USB 3.0 host, after checking the actual unit's power and cable requirements.
It is not a supported pick for a buyer who must have confirmed USB bus power, current operating-system or backup-software support, FireWire, Thunderbolt, RAID, console preparation, or direct-to-TV playback. The page's old software and OS descriptions do not establish current services or compatibility.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- B&H maps HDTD210XS3E1 to the silver 1TB Canvio Slim II, keeping it distinct from other Canvio Slim II capacities and model numbers.
- The page documents USB 3.0 and backward compatibility with USB 2.0 hosts.
- Its listed 10.6 × 7.3 × 1.0 cm dimensions and maximum 153g weight give a concrete basis for comparing bag space and carry weight.
What to weigh up
- Bus-powered operation and the need for an external adapter are not established, so the drive cannot satisfy a no-outlet requirement from this evidence.
- The 5 Gb/s USB 3.0 figure is an interface ceiling, not a measured file-copy rate; the source lists a 5400 rpm HDD.
- B&H marks its listing no longer available. Current Amazon model mapping, unit condition, seller cable/package, warranty eligibility, and software support remain unknown.

Full review: how the features affect your choice
What the features mean for you
What does model HDTD210XS3E1 identify?
B&H's product heading and manufacturer-number field map HDTD210XS3E1 to the silver 1TB Canvio Slim II portable external hard drive. That exact code matters because the Canvio Slim II name also appears on a separate 500GB Mac-oriented configuration and on a different 1TB retail code. The frozen source row's ASIN B00DQIEBRG is a historical identifier only; it has not been verified as today's exact Amazon offer. Treat 1TB as advertised capacity, with less space available after formatting. ([B&H exact-model listing](https://www.bhphotovideo.com/c/product/1022390-REG/toshiba_hdtd210xs3e1_1tb_canvio_slim_ii.html/overview), accessed 2026-10-13.)
Which computer connections does it document?
The exact-model page identifies USB 3.0 and says the interface is backward compatible with USB 2.0. That makes it a possible match for either of those documented host paths, though a USB 2.0 connection is limited by that older interface. B&H lists up to 5 Gb/s for USB 3.0 and up to 480 Mb/s for USB 2.0; these are interface rates, not observed throughput from this drive. The page does not establish Thunderbolt, FireWire, or a measured transfer result. Check the computer port and cable rather than assuming that a connector adapter changes the supported protocol. ([B&H specs](https://www.bhphotovideo.com/c/product/1022390-REG/toshiba_hdtd210xs3e1_1tb_canvio_slim_ii.html/overview), accessed 2026-10-13.)
Does the slim case make it a no-outlet drive?
The listing calls the unit portable and describes a brushed-aluminum design. It gives dimensions of 10.6 × 7.3 × 1.0 cm and a maximum weight of 153 g, figures that help a buyer judge whether it fits a laptop bag or a crowded desk. Those physical details do not establish its electrical power arrangement. The saved page does not say that the exact model is bus powered or that it never needs a separate adapter. The old listing includes a USB 3.0 cable in its original package, but that does not prove what a current seller supplies. Leave the drive out of a no-outlet shortlist until the actual unit and cable are confirmed. ([B&H overview and specs](https://www.bhphotovideo.com/c/product/1022390-REG/toshiba_hdtd210xs3e1_1tb_canvio_slim_ii.html/overview), accessed 2026-10-13.)
What does its 1TB HDD configuration mean for an archive?
B&H lists a 1TB capacity and 5400 rpm rotational speed. The capacity may suit a portable copy of documents, photos, or other files that do not fit a smaller archive drive, while the rotational-speed line identifies a mechanical-disk configuration. Neither figure is a reliability rating or a measured performance result. The page's USB ceiling cannot tell you how quickly this specific drive will copy a folder on your computer. Keep another copy of irreplaceable data and check the condition of any used drive; this review does not claim a tested unit or benchmark. ([B&H exact-model listing](https://www.bhphotovideo.com/c/product/1022390-REG/toshiba_hdtd210xs3e1_1tb_canvio_slim_ii.html/overview), accessed 2026-10-13.)
Are the old backup and Mac features current?
The page describes preloaded NTI Backup Now EZ as Windows-only, old Windows system requirements, a preloaded NTFS driver for Mac, and HFS+ reformatting for Time Machine. It also describes Pogoplug PC, a 10GB cloud offer, and password protection. These are historical product-page details, not evidence that a download, cloud account, encryption workflow, operating-system driver, or vendor support remains available now. A Mac buyer should verify the current computer and file-system plan independently; a buyer who already has a working backup routine need not count the old software as a benefit. The product source does not test any of these features on a current system. ([B&H overview and specs](https://www.bhphotovideo.com/c/product/1022390-REG/toshiba_hdtd210xs3e1_1tb_canvio_slim_ii.html/overview), accessed 2026-10-13.)
What should be checked before buying an actual unit?
The B&H page now says its offer is no longer available. That is a statement about that retailer page, not proof that no seller has the model. Search by the full HDTD210XS3E1 number and verify the label, capacity, included cable, power arrangement, condition, return terms, and any warranty eligibility for the actual unit. The historical ASIN should not be used as a direct product link without current exact-model evidence; the tagged Amazon destination searches by brand, model, and capacity. Current stock, price, seller package, and offer identity remain open.

Before you buy
Will it work with a USB 2.0 computer?
B&H lists USB 3.0 backward compatibility with USB 2.0. Verify the host and cable for the individual unit; USB 2.0's listed interface ceiling is lower, and no drive benchmark is claimed.
Can I use it without an outlet?
The saved exact-model page does not establish bus power or an adapter requirement. Check the actual unit and seller's cable before using it away from an outlet.
Is historical ASIN B00DQIEBRG a verified current Amazon listing?
No. It is retained as a historical source-row reference. The affiliate link searches for Canvio Slim II model HDTD210XS3E1 and does not assert a current exact offer.
Does it include current backup software or a current warranty?
The B&H listing describes old software and a limited three-year warranty for its original package, but it is marked no longer available. Current software support, warranty eligibility, and seller package are unknown.
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.
