October 29, 20169 yr Two SSDs installed to PC.... Samsung 840 (120Gb) for Windows and much newer Crucial CT500-200MX (500Gb) for flightsim software. The older Samsung reports MUCH better test results for average read speeds. Both plugged into sata 6Gbs M/B sockets. Both with exactly the same cables. Tried swapping plugs and cables. Also downloaded and installed latest motherboard drivers from Asus. Any ideas? Samsung results: Random access: 0.1ms Average Read: 378.7 MB/s Crucial results: Randon access: 0.1ms Average read: 204.1 MB/s Windows 10 (x64) - X-Plane 11 - M/B: Asus ROG Maximus IX Hero - CPU: i7 7700k (@5.0GHz) - RAM: 32Gb Corsair Vengeance LPX DDR4 @ 3200MHz - Video: GTX1080ti - Cooling: Custom water loop (EK 140 Revo D5 pump/res combo, EK EVO CPU block, EK XE360 Rad)
October 30, 20169 yr Tried different sockets? Have you tried different benchmarking software? 4790K @4.9GHz, 32GB DDR3, 1080Ti, W10-64bit
October 30, 20169 yr Is RAPID turned on for the Samsung drive? I think it might be called Momentum for Crucial drives. RAPID or Momentum only works for boot devices, so my guess is you have RAPID on for the Samsung drive. Latest SSD firmware on both? Configured properly in BIOS?
October 30, 20169 yr Commercial Member Just because it's newer doesn't automatically mean it's faster. What do the reviews say the Crucial can do on random reads? Cheers! Luke Kolin I make simFDR, the most advanced flight data recorder for FSX, Prepar3D and X-Plane.
October 30, 20169 yr Also, not all SATA III chipsets are created equal. My motherboard has some Intel Express ports and some ASMedia ports. Both are supposedly capable of 6Gb/s but the Intel ports are generally considered to be faster than ASMedia. It may be worth checking the type of ports your SSDs are plugged in to - they may be different. i7-14700k | Asus ROG STRIX Z790-F Gaming WIFI | 32GB DDR5 RAM | MSI RTX 4080 Super | WD Black SN850X 1TB & 2TB | Corsair HX1000i ATX3.0 | MSI MAG401QR 40" monitor | Win 11 Pro 64-bit | Meta Quest 3
October 31, 20169 yr Just because it's newer doesn't automatically mean it's faster. What do the reviews say the Crucial can do on random reads? Cheers! A quick search indicates it's under performing by quite a bit. Of course 550Mb/s is it's top rated speed not average. 4790K @4.9GHz, 32GB DDR3, 1080Ti, W10-64bit
October 31, 20169 yr Author This is really strange... All firmware and drivers up to date. Ports and cables checked and or swapped. Still the poor results. I doubt I'll get a response, but I'll try emailing Crucial Windows 10 (x64) - X-Plane 11 - M/B: Asus ROG Maximus IX Hero - CPU: i7 7700k (@5.0GHz) - RAM: 32Gb Corsair Vengeance LPX DDR4 @ 3200MHz - Video: GTX1080ti - Cooling: Custom water loop (EK 140 Revo D5 pump/res combo, EK EVO CPU block, EK XE360 Rad)

Lesson.... Never go with manufacturers or synthetic test results. Real world test results are very different:-( Windows 10 (x64) - X-Plane 11 - M/B: Asus ROG Maximus IX Hero - CPU: i7 7700k (@5.0GHz) - RAM: 32Gb Corsair Vengeance LPX DDR4 @ 3200MHz - Video: GTX1080ti - Cooling: Custom water loop (EK 140 Revo D5 pump/res combo, EK EVO CPU block, EK XE360 Rad)
October 31, 20169 yr Phil, I looked for a more appropriate thread to ask, but I hope you don't mind me using this one. How are you doing? Have you been recovering as expected from the operation and has life sort of returned to something more like normal? Hoping and trusting in all the best for you. Kind regards,
