Happy Presidents' Day! As we look toward the end of the Presidents' Day sales, there are still plenty of deals to be had at some of our favorite tech retailers. Today's deal is on one of Seagate's IronWolf Pro HDDs (20TB capacity) for $419.99, available from Newegg. Hard drives aren't as popular for speedy data access as they used to be — you'll want one of the best SSDs for that task — but they're still great for cheap and deep storage for data that doesn't need lightning-fast access, like pictures, videos, and backups. At this $419.99 sale price, you're saving $80.01 from the $500 list price.

You might think that mechanical hard disk drives are a relic of the past and are far too slow for modern needs, and you're not wrong. However, there's a caveat that you don't always need blisteringly fast cutting-edge speeds, and of course, the cost savings with older tried and tested tech. HDD drives are nowhere near as fast as the latest PCIe Gen5 SSDs, but what they lack in terms of speed, they make up for in price, capacity and longevity. These particular drives from Seagate are designed to operate continuously, 24/7, every day, while being reliable, and keeping your important data safe.

The IronWolf Pro is a 3.5-inch internal drive with a 7200 RPM spin speed and SATA connectivity. The SATA III interface has a 6 Gb/s transfer bandwidth, a read/write transfer speed of 285 MB/s, and a workload rating of up to 550TB per year. It uses Conventional Magnetic Recording (CMR) technology and is much faster than cheaper models that use Shingled Magnetic Recording (SMR). If you're looking for some of the best drives on the market to supply your NAS setup, then this IronWolf Pro deal should be on your radar.
