The Samsung SSD update! So the drives arrived yesterday and performed poorly. I tested them as a primary and as a secondary and did not get good results. On the benchmark test they did better than the other SSDs but in real test they did worse. Then I downloaded the Samsung SSD tool known as Samsung Magician and found an option to go into RAPID mode which will basically enable DRAM. Then benchmark test showed write speeds of over 2000 MB/s but it did not reflect in a real copy paste test. I still got the same slow speeds. The Samsung Magician shows that the drives have genuine firmware and up to date. It is time to get an official from Samsung on this thread.  Can someone on this thread get one to join here or to tell me how to get in touch with the support. I have attached 3 images. The Benchmark results. From HD to SSD and from SSD to HD. The faster one is the SSD to HD. ... View more

Thank you for the tips on the sometimes required firmware update.   Two of the drives are only 1 year old and the other 2 were tested by a computer at the shop and two at home and failed. I got rid of them as soon as I could and will sell the two 1 year old SSds for a big loss to just to get rid of them because I hate having H/W that I thought is great but did not meet the expiations. The final results will confirm that quality matters in performance. I will post them in about 2-3 weeks time. Depending the arrival of the disks. ... View more

Based on the feedback and the new research that I did. I place an order for 2 Samsung EVO SSD. Will update with the results soon. ... View more

Thanks for the details. This disks performed the same on the PC of the shop that I tested them at. All the devices support trim. I have HD Sentinel and it is all fine. Win 8.1 and 10 all 64bit. Maybe SATA and NVME don't perform the same. My only inquiry is if Samsung is known to always keep the same speed or not.  I saw in several videos that it does but it was not clear if they are SATA or NVME. If anyone has the "Samsung EVO 860 SSD" SATA then please let me know if it works the same while it is the main drive and full. I just do not want a drive that will drop off to 10-30MB/s after it is 50% full or at all. It should still work even if it is 90% full. A drive that does not only performs well until it runs out of cache is pointless. ... View more

They are old upgraded laptops, so no chance for PCI cards. Every once in a while I upgrade a part of them. It is more like a hobby. One of them is working on SATA II interface. Both are on AHCI interface. The newer one has an added internal drive that is a Seagate 7200RPM and there is no drop off in speed at all. It is the only good one that I have but it is suppose to be slower than the SSD write speed. The 1st batch SSD was a Transcend and the 2nd one is TEAMGroup. Both work perfectly fast until I reach about 50% storage space. Then the drop off starts to occur. That is the only thing that i want. It is that the speed remains the same. Not at full speed but no huge drop offs either. Because that makes it completely worthless to me. ... View more
