SATA vs. PCIe SSDs Performance Test with Linus
So, the tech-savvy among you will already know that SSDs or solid state drives perform better than mechanical hard drives for everything from everyday use to professional applications. And the especially tech-savvy among you will probably know that we’ve reached both a theoretical and real-world performance limit for SSDs that connect to your PC using a SATA or Serial ATA connection with PCI-Express SSD, so drives that can connect directly to a controller on your CPU using a socket on the motherboard emerging as the replacement. But what most of you probably haven’t seen any kind of practical, that is, real world demonstration of the bottlenecks that exists in mechanical drives and solid-state drives using SATA interfaces, until now! This is our uncompressed video capture machine hooked up to a gaming PC. It uses a 4K capable HDMI capture device to obtain the best quality output from a video card or video camera. But that comes at a cost with fairly short HD video clips taking up tens or even hundreds of gigabytes of space like that! So, I’m going to show you how well this works with a hard drive how well it works with a SATA SSD like the HyperX Savage and how well it works with a state of the art PCIe SSD like the HyperX Predator. So we’ll start with our hard drive. As you can see the disk speed tool that Black Magic providers already telling us that this is straight up not going to work. But darn it, it that won’t keep us from trying! And it’s gone. Out test bench fails to capture pretty much instantly. Next up is our HyperX Savage SSD. The disk speed test has an awful lot more checkboxes this time but once again indicates that it’s not going to work for 1080p at 60 fps, full color depth, etc. But if I didn’t listen the first time how likely is it that I’m going to start listening now? After a few seconds it’s done. Just like every other SATA-based SSD we’ve ever tried with this before. So, finally, we get to our Predator PCIe SSD rated at whopping 1400MB/s read and more importantly, for this test, 1000MB/s write. The green check boxes are all lit up. All systems are evidently “go”! And until we fill this drive up there are no dropped frames to interrupt our recording. We have overcome the SATA bottleneck. Now, to be clear, running multiple SATA SSDs in RAID 0 can also overcome the SATA bottleneck. But it hurts reliability and on most motherboards it doesn’t really scale well past two to three SSDs while with PCI Express the sky is pretty much the limit. Please don’t throw your SSD though. Not that sky. Anyway I think we’re done here. Thanks for watching. I’m Linus I’ll see you again next time, that is, assuming that you want there to be a next time in which case you probably hit like on the video and get subscribed so that will HyperX bring me back for more of these spots.
