Our take
The BIPRA S2 250GB is a narrow-fit portable HDD for a buyer whose archive fits within its listed capacity and whose setup calls for USB 2.0. The checked listing describes a 2.5-inch black drive that does not need a separate power supply. Its main compromises are the small capacity, an older connection, and uncertainty about the exact filesystem and current seller configuration. Keep it as a working product identity rather than linking the historical Amazon ASIN as a verified offer.
A small archive or working set that fits within 250GB, needs the documented USB 2.0 interface, and benefits from a listing-described no-adapter setup, once the seller's exact configuration is confirmed..
Buyers who need more than 250GB, a documented USB 3.0 interface, FireWire, a guaranteed shipped filesystem, a verified current Amazon offer, or confirmed cable and unit condition.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The checked listing identifies a black 250GB BIPRA S2 portable HDD with a 2.5-inch form and USB 2.0.
- The listing says a separate power supply is not required, which can simplify a no-outlet setup.
- BIPRA's catalog distinguishes the USB 2.0 S2 family from the USB 3.0 S3 family.
What to weigh up
- 250GB is the only supported capacity for this working identity and does not meet higher capacity floors.
- USB 3.0, FireWire, current host support, and measured transfer performance are not established.
- The exact part code, shipped filesystem, seller cable, current Amazon mapping, and individual-unit condition remain unverified.

Full review: how the features affect your choice
What the features mean for you
Is 250GB enough for the files you plan to keep?
The checked Yaxa listing identifies the black S2 option at 250GB and a portable 2.5-inch form. That gives a concrete nominal capacity for a small working set or a limited archive, but it is not a fit when your required floor is above 250GB. Formatted usable space will be lower than the advertised capacity, and the saved sources do not provide a measured usable-space figure. Keep a separate backup for important files rather than treating a single older drive as the only copy. Do not borrow a capacity from another BIPRA S2, S3, or U3 listing just because the family names look alike. ([Yaxa product listing](https://yaxa.co/products/s2-2-5-pulgadas-usb-2-0-ntfs-disco-duro-externo-portatil-negro-1tb-1000gb), checked 2026-10-14.)
Does USB 2.0 fit the computer you will use?
The product page describes the S2 option as USB 2.0, and the BIPRA catalog lists an S2 USB 2.0 250GB drive separately from an S3 USB 3.0 250GB product. That makes the S2 a candidate when the required device connection is USB 2.0; it does not turn this identity into a USB 3.0 model or establish a measured transfer result. Check that the computer has a usable USB path and that the seller's actual cable fits both ends. The saved evidence does not establish current operating-system support or test this drive on a present-day host. ([Yaxa product listing](https://yaxa.co/products/s2-2-5-pulgadas-usb-2-0-ntfs-disco-duro-externo-portatil-negro-1tb-1000gb); [Yaxa BIPRA catalog](https://yaxa.co/brand/bipra), checked 2026-10-14.)
Can it work where there is no outlet?
The checked Yaxa product page says the drive does not require an external power source. That is useful for a portable setup, but it remains a listing-level description, not a check of a current seller's unit, working cable, or condition. Confirm the exact port and cable with the seller and test the drive before moving important files. The source does not establish cable length, a current package, or host-specific compatibility. ([Yaxa product listing](https://yaxa.co/products/s2-2-5-pulgadas-usb-2-0-ntfs-disco-duro-externo-portatil-negro-1tb-1000gb), checked 2026-10-14.)
Which filesystem will the seller's option use?
The Yaxa page checked for this profile titles the 250GB option as NTFS. A previously saved ExternalHardDrivesi index describes a BIPRA S2 250GB listing with FAT32 wording, but that exact page returned a cache miss when reopened on 2026-10-14. Yaxa also lists other S2 capacity and format options, so a family-level page cannot prove which configuration a seller will ship. Treat the filesystem as unresolved for the offer you buy: ask the seller to identify the exact selection and check the drive before loading data. The saved evidence does not establish a specific file-size limit or current operating-system behavior. ([Yaxa product listing](https://yaxa.co/products/s2-2-5-pulgadas-usb-2-0-ntfs-disco-duro-externo-portatil-negro-1tb-1000gb); [ExternalHardDrivesi saved listing](https://www.externalharddrivesi.com/products/bipra-s2-2-5-inch-usb-2.html), direct fetch returned a cache miss on 2026-10-14.)
What should you confirm before choosing it?
Search for BIPRA S2 250GB USB 2.0 and verify that the seller is describing the black 2.5-inch S2 option, not the separate USB 3.0 S3 or BIPRA U3 products. Historical ASIN B07C559JLH remains unverified as a current exact offer. The secondary Yaxa listing displays a different ASIN in its technical information; that is not treated as a mapping for the historical row or as a direct Amazon listing. Confirm the selected capacity, filesystem, cable, unit condition, and return terms with the seller. No saved source supplies a measured speed, durability rating, current Amazon variant, current price, stock, or host-specific compatibility.

Before you buy
Does historical ASIN B07C559JLH prove the current Amazon offer is this drive?
No. It remains a historical reference only. Use the tagged BIPRA S2 model search and confirm the seller's exact configuration.
Is this the USB 3.0 BIPRA S3 250GB?
No. The saved catalog evidence distinguishes the USB 2.0 S2 from the USB 3.0 S3 family. Keep those product identities separate.
Does the 250GB S2 definitely ship as FAT32 or NTFS?
The checked Yaxa page uses NTFS wording for its 250GB selection, while a saved indexed listing uses FAT32 wording and could not be reopened. Confirm the selected filesystem with the seller.
Can it run without a wall adapter?
The checked Yaxa listing says it does not need an external power supply. The actual offer's cable and an individual used unit's condition still need checking.
Does USB 2.0 guarantee a particular transfer speed?
No. The saved sources identify an interface but do not establish a measured file-transfer result for a computer, cable, or workload.
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.

- Yaxa indexed product listing and BIPRA brand catalog; exact 250GB option checked 2026-10-14 ↗ — checked October 14, 2026.
- Yaxa indexed product listing checked 2026-10-14: product heading and variant selector identify a black BIPRA S2 USB 2.0 portable HDD with a 250GB option and 2.5-inch form; the Q&A says no external power supply is required. The page's NTFS wording and older FAT32 index wording are not treated as proof of the filesystem in a current seller offer; a different ASIN shown by the secondary listing is not used as an Amazon crosswalk. ↗ — checked October 14, 2026.
- Yaxa BIPRA catalog checked 2026-10-14: lists S2 USB 2.0 250GB separately from S3 USB 3.0 250GB and other S2 format/capacity options; family context only, not a part-code or historical-ASIN crosswalk. ↗ — checked October 14, 2026.
- Previously saved indexed listing wording identifies a 250GB black S2 and mentions FAT32; direct page fetch returned a cache miss when retried 2026-10-14, so this wording is retained only as the reason filesystem remains unresolved. ↗ — checked October 14, 2026.
