Today at Amazon you can save up to 20% on memory and storage devices from SanDisk and WD. This is part of Amazon’s daily deals, so the prices are only good through the end of the day. Still, you have a lot of ways to save here. The capacities vary between 64GB and 6TB. The items vary from microSD cards for your security cameras to portable external hard drives for carrying your media around with you. There are internal drives like the WD Black SN750 M.2 NVMe SSD on sale for $97.49 from a street price of $130 and small external options like the SanDisk Ultra Fit USB 3.1 flash drive available for $45.29 (down from $56).

The 1TB SN750 drive is a Gen4 solid state drive. It can hit read and write speeds up to 3,600 MB/s and 2,900 MB/s respectively. It’s a great option if you need speed at an affordable price, and it just blows SATA SSDs out of the water with how fast it is. Maintain peak performance and do it with 30% less power consumption than previous generations. Make sure your motherboard supports this type of drive before you buy it.

Concerned more with space than speed? Grab the WD Red 4TB hard drive on sale for $77.99. That’s $20 off its street price. The WD Red series is all about durability and capacity, so you’re getting a drive that can handle a ton of work. It supports a 180 TB per year workload and works great with network-attached storage devices like the Synology DiskStation DS220j or something similar.

There are plenty of other options, too, including smaller drives and microSD cards. Browse the full sale before all the deals disappear.
