Our take
Choose the G-Drive Q 913003-01 when a desk-oriented 500GB HDD and one of its specifically listed legacy connections match the computer. Its four listed host interfaces are the main reason to consider it; the unknown power arrangement and uncertain current host compatibility make a seller check essential.
A buyer planning a desk-based 500GB HDD for a confirmed USB 2.0, FireWire 400/800, or eSATA host, after checking the actual drive, power supply, cables, and present compatibility.
It is not a documented fit for a USB 3.0-only, Thunderbolt, bus-powered, console, RAID, or direct-TV requirement. The saved page does not establish current operating-system support or a current Amazon offer.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Newegg maps the exact 913003-01 to a 500GB 3.5-inch external HDD.
- The model page lists USB 2.0, FireWire 400, FireWire 800, and eSATA.
- The product description identifies a vented, fanless aluminum enclosure with feet that leave airflow beneath it.
What to weigh up
- The 3.5-inch desktop format is not a pocketable portable-drive configuration.
- The saved exact-model page does not establish bus power, adapter requirements, or which cables a present seller includes.
- The Newegg page showed out of stock; the old Amazon ASIN and period Mac wording do not prove a current exact offer or present-day compatibility.

Full review: how the features affect your choice
What the features mean for you
Does model 913003-01 identify the G-Drive Q?
Newegg's exact-model page identifies G-Technology's G-DRIVE Q as model 913003-01, with 500GB nominal capacity and a 3.5-inch external hard drive. The full model number matters because G-Technology used similar G-Drive names for other portable and desktop configurations; this review applies to the Q and not to those other products. Source row 72 carries historical ASIN B000F4CVAI, but that old row does not verify a current Amazon seller's exact unit. Search by the complete model number, then compare the label on the actual drive and the listing details. Newegg marked its own listing out of stock at the 2026-10-13 check. That is a status for this retailer page, not proof that no other seller has the model. ([Newegg exact-model listing](https://www.newegg.com/g-technology-model-913003-01-500gb-external/p/N82E16822205004), checked 2026-10-13.)
Which computer connections are documented?
The exact-model specification lists USB 2.0, FireWire 400, FireWire 800, and eSATA. That four-interface range is the product's clearest distinction: it can be considered for a legacy host that has one of those matching protocols, while a buyer with only a modern USB-C or Thunderbolt port still needs to verify a suitable, working adapter chain. A connector that physically fits does not convert one protocol into another. The saved page does not list USB 3.0 or Thunderbolt for this model, so do not select it for those requirements. The page's historical plug-and-play wording for Mac OS X describes its period configuration; it is not a present-day driver or operating-system compatibility test. Confirm the interface on the seller's actual unit and check cable and adapter availability before planning around FireWire or eSATA. ([Newegg exact-model listing](https://www.newegg.com/g-technology-model-913003-01-500gb-external/p/N82E16822205004), checked 2026-10-13.)
Is it designed for carrying or for a desk?
Newegg lists a 3.5-inch form factor, which makes the G-Drive Q a desk-oriented external drive rather than a compact 2.5-inch portable model. That difference affects where it fits and how a buyer should plan the setup: allow room for the enclosure and its cables instead of treating it like a pocket drive. The saved exact-model source does not identify the power arrangement. A 3.5-inch size alone is not enough evidence to say whether this specific unit needs a separate adapter or what adapter it takes. It also does not establish USB bus power. Anyone who needs to work away from an outlet should leave the power requirement unresolved until the seller confirms the exact adapter and the drive's behavior. The separate interface choices do not resolve the power question. ([Newegg exact-model listing](https://www.newegg.com/g-technology-model-913003-01-500gb-external/p/N82E16822205004), checked 2026-10-13.)
What does 500GB mean for an archive?
The listed 500GB is nominal capacity; the space available for files is lower after formatting and the computer's file-system overhead. Newegg also lists a 7200 rpm disk and 8MB cache. Those are configuration details, not a measured copy rate, guarantee of reliability, or reason to assume a certain workload result. The page's promotional text discusses an internal SATA II data rate, but that number does not measure transfers through USB 2.0, FireWire, or eSATA on a particular host. If the goal is a small legacy archive, 500GB may be a useful documented floor; if the collection is larger or needs redundancy, this single drive's capacity and the source's lack of a RAID claim should be considered plainly. Keep another copy of important files, and assess the individual drive's condition before trusting it with the only copy. ([Newegg specifications](https://www.newegg.com/g-technology-model-913003-01-500gb-external/p/N82E16822205004), checked 2026-10-13.)
Does the fanless enclosure change everyday use?
The product description calls the aluminum enclosure heavily vented and fanless, and describes feet that leave airflow beneath it. That gives a practical placement cue: avoid blocking the vents or squeezing the enclosure into a closed, crowded space. A fanless design removes a moving fan from the listed cooling arrangement, but the page does not provide a measured noise level or temperature test, so this review does not promise silent operation or a particular thermal result. Aluminum construction and ventilation are not a drop, water, dust, or travel-protection rating. This is a desk-oriented drive with a vintage interface set; buyers should choose it for a confirmed host connection and a suitable placement, rather than read the enclosure description as proof of durability or current performance.

What should be checked before buying a unit now?
The rechecked Newegg page showed this model out of stock, and the historical Amazon ASIN is not confirmed as a current exact offer. Use the affiliate search for G-Technology G-Drive Q 500GB 913003-01, then verify that the actual listing and drive label agree. Ask which USB, FireWire, and eSATA cables or adapters are included, whether the exact unit needs an external power supply, and whether the seller has tested the drive and can describe its condition and return terms. Current operating-system support, warranty eligibility, package contents, and present compatibility are not established by the old Mac wording or by the model specification. No current price, availability, hands-on test, or buyer-review summary is asserted here.

Before you buy
Will it work with a USB 2.0 host?
The exact-model listing includes USB 2.0. Confirm the port, cable, and current operating-system path for the actual drive; the listing does not establish present-day host support.
Does it have FireWire and eSATA?
Newegg lists FireWire 400, FireWire 800, and eSATA alongside USB 2.0. Verify the seller's unit and included cables or adapters.
Can it run without an outlet?
The saved exact-model source does not establish bus power or an external-adapter requirement. Check the actual drive and seller's power supply before relying on it away from an outlet.
Is ASIN B000F4CVAI a confirmed current Amazon offer?
No. It is retained as a historical source-row reference. The affiliate destination searches for G-Technology G-Drive Q model 913003-01.
Is 7200 rpm or the SATA II figure a measured copy speed?
No. Newegg lists 7200 rpm and 8MB cache, and its overview mentions an internal SATA II rate. These are not measured transfer results for the external drive on a particular host.
Where can I check the current price?
