While current PCIe 4.0/5.0 SSDs leave SATA SSDs in the dust when it comes to speed, SATA SSDs still have their place. How do they fit into the price-to-performance equation? Let’s break it down: 500MB/s theoretical bandwidth, a 50K IOPS limit, AES-256 encryption support... So, what do *you* use SATA SSDs for? Is sequential read/write, random IOPS, or cost the most important factor? Do you still opt for a SATA SSD when building a new system?
SATA SSDs: Are They Really a Hassle?

A year ago, I had this exact discussion in my home lab when I wanted to replace my old M.2 SATA SSD with a PCIe 4.0 NVMe drive. At the time, I needed a fast, reliable drive for my virtual development environment—but not for sequential read/write operations, rather for hundreds of small database queries per second. While the PCIe SSD was theoretically faster, the control software of my virtualization tool (VirtualBox) never had issues with the tiny IOPS of the SATA SSD. The real deciding factor: the 500MB/s bandwidth was more than enough for my random database operations, and unfortunately, so was the AMD X570 motherboard’s limit—the PCIe 4.0 SSD was overkill.
Where SATA SSDs still make sense for me today: in old office PCs on a tight budget or as a secondary drive for backups. My dad, for example, uses a 1TB SATA SSD as the system drive in his 2015 gaming PC—no bottleneck in everyday use, but a massive speed boost over the old HDD. The Acer Predator Helios with its 7200rpm laptop drive was a nightmare to boot, while the Crucial MX500 now starts in under 10 seconds. Even with AES-256 encryption and the SATA limit, it still feels lightning-fast because real-world demands are far below the specs. For the average user, this is often more than enough, especially when you consider that even high-end PCIe SSDs only shine in specialized workloads.
Wow, this discussion is really interesting, especially when you consider that the prices of next-gen PCIe SSDs might soon make SATA SSDs obsolete. In my opinion, the biggest strength of SATA SSDs is actually their compatibility and simplicity. For example, if you have an old laptop or a system with an older motherboard that doesn’t support PCIe 4.0, just slapping in a SATA SSD is both cheap and hassle-free. What I’m wondering is: when PCIe 5.0 SSDs become mainstream, will their prices drop enough, or will SATA keep its price advantage and stick around?
