At first, I suspected thermal throttling, but even after the overnight transfer was complete, the issues persisted. When the drive was around 70% full, write speeds became incredibly slow and sporadic, ranging from 0.9 to 8 MB/sec, despite testing it on both SATA and USB. I even reformatted the drive completely, but the transfer speeds remained broken. Ultimately, I returned the drive, assuming it was a rare defective unit.
However, I've noticed similar reviews from others where transfer speeds plummet after sustained writing during a backup, which leads me to wonder if reduced write speeds are also occurring. Other brands like SP and TEAMGROUP are similarly omegle owespeedtest priced and may source parts from the same manufacturers, but the Samsung ones are almost twice the price. However, even the 870 EVOs have been reported to be prone to failure.
Have you had similar experiences or problems with SSDs?
