Hello Guys,
I had purchased Samsung Evol Plus 1TB & 500GB NVME last year around Nov-Dec 2020. Recently I noticed, CrystalDesk Bbenchmark & Samsung Magician Benchmark is showing only following speeds:
  1. 1TB:- Read-3400MB, Write: 2200MB
  2. 500GB:- Read: 900MB, Write 863MB
When drives were brand new, I was getting 3300+ for both read/write for both drives.
Why is there a sudden drop in speed?
Should I request a replacement?
(My specs are: Intel i5 8600K CPU, ASUS Z390-F Gaming M/B which support PCIE Gen3, Corsair 16GB 3000Mhz RAM, Disk space available more than 50% on both drives. X4 mode is enabled for both drives in BIOS. Using UEFI/GPT configuration. Multiple OSes are installed on 1TB drive, MacOS/Win10/Ubuntu/openSUSE and only Win10 installed on 500GB Drive.)
Appreciate your feedback, Thanks
Sagar

* Performances may vary depending on SSD’s firmware version and system hardware & configuration. Performance measurements based on IOmeter 1.1.0. The write performances were measured with Intelligent TurboWrite technology being activated. The sequential write performances after Intelligent TurboWrite region are: 400 MB/s(250GB), 900 MB/s(500GB), 1,700 MB/s(1TB) and 1,750 MB/s(2TB)
