Get This Price

For just $620, below its 30-day average of $843.75. Over the past 90 days, this drive has averaged $647, so today's price undercuts that by $27. While not an all-time low. This is one of the better opportunities to grab high-capacity SATA storage without waiting for seasonal sales.

What You're Getting

The WD Blue SA510 delivers 4TB of storage in the familiar 2.5-inch form factor. It connects via SATA III interface with sequential read speeds up to 560 MB/s and write speeds up to 520 MB/s.

This drive works with both desktops and laptops, offering reliable performance for everyday computing tasks, game storage, or media libraries.

Who This Is For

Best for: PC builders needing secondary storage, laptop users upgrading from mechanical drives, or anyone with a growing game library. The 4TB capacity handles large media collections and modern game installations that routinely exceed 100GB each.

Wait if you need NVMe speeds for your primary drive or if you can hold out for deeper holiday discounts.

The Caveat

This is a SATA drive, not NVMe, so you won't get the fastest possible transfer speeds. The 560 MB/s read cap is fine for most users but lags behind modern PCIe 4.0 drives that hit 7,000 MB/s.

Also consider that 4TB SSDs from other brands sometimes dip lower during major sales events.

Final Verdict

At $620, this WD Blue SA510 makes sense if you need reliable high-capacity storage today. The $224 savings versus its recent average price justifies immediate action for users with full drives or new builds in progress. For everyone else, monitor prices through spring for potentially better deals.
