A two-year warranty adds protection, and this is one of the cheapest cost-per-gigabyte external hard drives we’ve ever seen.

UnionSine 500GB 2.5": was $33 Now $29 at Amazon
Save $4 with Prime
This value option from UnionSine won’t blow you away, but at this price - possibly the lowest price we’ve seen for an external HDD - it’s hard to avoid recommending it to anyone who occasionally needs to transfer data across devices. The read and write speeds on USB 3.0 run as high as 133MB/s, which is just fine in a pinch.

Save $21

UnionSine 10TB 3.5": was $185 Now $164 at Amazon
Save $21 At the other end of the scale, this bulkier 10TB option offers a small boost to speeds thanks to USB 3.2 connectivity, but yet more value in terms of the storage capacity you get for the money. The potential snag here is that, being a larger drive, you will need to power it with an included power supply, so it’s not exactly plug and play.

Amazon Prime Day hard drive deals: what to expect

Amazon Prime Day Hard Drive deals: FAQs

Has Amazon Prime Day 2024 ended?

Yes. Amazon Prime Day 2024 came to a close on 17th July at 23:59 - but you can still find discounts available on the site. 

When is the next Prime Day 2024?

Amazon hasn't revealed the precise dates for the next Prime Day, but we're expecting it to arrive in October. This will be followed by the Black Friday sales in November. 

Will I need an Amazon Prime Day subscription to get Prime Day portable hard drive deals?

Always! And it’s never been so easy to get your hands on a subscription, either, because you don’t have to spend money – if you haven’t been a member for a year, just sign up for a free thirty-day trial to take advantage of the price drops. And if you’re already a member, you’re golden.

How do I become an Amazon Prime member?

You need to be an Amazon Prime member in order to get access to Prime Day deals, which costs $14.99 per month or $139 for a year. 

However, new subscribers can take advantage of the 30-day Amazon Prime free trial to buy the deals. You can only use this if you've never been a member before, so it won't be available if you've used it already or if you've signed up for Amazon Prime in the past.

While on the free trial, you get all the other membership benefits including free shipping, access to Prime Video and much more. Do read our Amazon Prime review for full coverage of what you get as part of a membership. That can help you decide if you want to cancel Amazon Prime once your free trial has ended to avoid being charged the monthly fee.

Which hard drives will be discounted on Prime Day?

Hard drives are commoditized these days thanks to the popularity of SSDs and relatively cheap prices, so companies like WD, LaCie and Seagate are always keen to offer deals to help differentiate their products. That bodes well for customers on Prime Day, where almost everything will be available with a discount.
