Seagate also includes its Toolkit software if you want full control over your backups.</p><p>The drive is powered by an external adapter, so it's intended to stay on a desk rather than travel around with a laptop.</p><h2 id="price-context-amp-historical-value-2">Price context & historical value</h2><p>The $139.97 reduction from $829.96 to $689.99 works out at almost 17% off, bringing the cost down to around 2.9 cents per GB. That sounds like a great saving, but context is important here. At the end of December 2025, Best Buy sold the same hard drive for just $279.99, reduced from $329.99. That makes today's $689.99 deal a stunning $410 more expensive than that previous sale price — or around 146% higher.</p><p>The comparison shows just how dramatically storage prices have changed in a year. So while you're saving nearly $140 against today's regular price, this is far from the cheapest deal ever.</p><p><em>For more shopping options, take a look at our roundup of the </em><a href="https://www.techradar.com/news/best-external-desktop-and-portable-hard-disk-drives" target="_blank"><em>best external hard drives.</em></a></p><h2 id="should-you-buy-it">Should you buy it?</h2><p>✅ <strong>Buy the 24TB Seagate External HDD if... </strong></p><p>You need a huge amount of storage now and would rather keep everything on a single external drive than manage several smaller ones. The USB 3.0 connection also provides considerably more bandwidth than the mechanical hard drive itself requires for file transfers.</p><p>❌ <strong>Skip the 24TB Seagate External HDD</strong> <strong>if... </strong></p><p>You can wait for storage prices to improve or for a better, bigger promotion. This is a desktop hard drive rather than a portable model so requires the supplied 18W power adapter as well as a USB connection. You can't simply plug it into your laptop and use it anywhere.</p><h2 class="article-body__section" id="section-also-consider"><span>Also consider</span></h2><div class="product"><a data-dimension112="b0138590-bbe5-11f1-a453-15aa142e7765" data-action="Deal Block" data-label="2TB Portable Hard Drive" data-dimension48="2TB Portable Hard Drive" data-dimension25="$129.99" href="https://www.amazon.com/Seagate-Touch-Desktop-Drive-STNB16000400/dp/B07CRG94G3/?th=1" target="_blank" rel="nofollow"><figure class="van-image-figure " ><div class='image-full-width-wrapper'><div class='image-widthsetter' style="max-width:500px;"><p class="vanilla-image-block" style="padding-top:100.00%;"><img id="moKnEdhdahBAMEWGEBPBBh" name="seagate-2tb-portable-hard-drive--usb-30--9c500586-ce41-48c9-9e8c-c456f68411cf.jpg" caption="" alt="" src="https://cdn.mos.cms.futurecdn.net/moKnEdhdahBAMEWGEBPBBh-1920-80.jpg" mos="" align="middle" fullscreen="" width="500" height="500" attribution="" endorsement="" credit="" class=""></p></div></div></figure></a><p><strong><a href="https://www.amazon.com/Seagate-Touch-Desktop-Drive-STNB16000400/dp/B07CRG94G3/?th=1" target="_blank" rel="nofollow" data-dimension112="b0138590-bbe5-11f1-a453-15aa142e7765" data-action="Deal Block" data-label="2TB Portable Hard Drive" data-dimension48="2TB Portable Hard Drive" data-dimension25="$129.99">2TB Portable Hard Drive: was $149.99 now $129.99</a></strong><br>This much cheaper portable hard drive provides 2TB storage, USB 3.0 connectivity, plug-and-play operation, simple backup capabilities, an Adobe Creative Cloud trial and a one-year warranty.<a class="view-deal button" href="https://www.amazon.com/Seagate-Touch-Desktop-Drive-STNB16000400/dp/B07CRG94G3/?th=1" target="_blank" rel="nofollow" data-dimension112="b0138590-bbe5-11f1-a453-15aa142e7765" data-action="Deal Block" data-label="2TB Portable Hard Drive" data-dimension48="2TB Portable Hard Drive" data-dimension25="$129.99">View Deal</a></p></div><ul><li><a href="https://www.bestbuy.com/site/hard-drives/external-portable-hard-drives/pcmcat186100050005.c?id=pcmcat186100050005" target="_blank">Shop all external hard drives at Best Buy</a></li><li><a href="https://www.amazon.com/External-Hard-Drives-Storage-Add-Ons/b/ref=dp_bc_4?ie=UTF8&node=595048" target="_blank">See all external hard drives at Amazon</a></li></ul> </article> ]]>
