hi all, new to the forum here and hoping to find some answers for a problem I'm having with the 840 evo. After some research on the net, this thread seems to have the most knowledgeable posters. I bought my 840 evo in 11/2014, which was blazing fast initially until the performance degradation issue hit. I have since then updated to the latest firmware EXT0DB6Q, which subjectively seems to have fixed the problem. However, over time, the computer seems to slow down despite the latest firmware. In 4/25/2016, using the Magician's performance benchmark, my random read/write is 29K/23K and seq read/write in 548/528 I did an advanced performance optimization back then on the Magician software, which restored the random read/write to 90K/50K. Then yesterday, 7/7/16, the computer started slowing down significantly, and a recheck of SSD performance found that random read/write is back down to 29K/23K . I repeated the advanced performance optimization and benchmark found random read/write is back up to 90K/65K. However, the computer seems to have these periodic 0.5 sec freezes here and there which I want to attribute to the evo 840.
Is periodic advanced performance optimization needed every 2-3 months to maintain the optimal performance of the drive? Has that been the experience for other folks who own the 840 evo? Or did I get a bad batch? And are people happy with having to do advanced performance optimization every 2-3 months? Does Samsung consider that fixed?
I'm still under warranty until 11/2017. What has other folks' experience been with warranty service. It seems to me people just get another 840 evo refurb, which I really don't want. Has anyone had success with getting Samsung to give a 850 evo replacement instead?
I'm considering getting a new SSD 480-500Gb capacity. Any recommendations? Do folks pretty much agree with Sean's SSD buyers guide suggestions? It seems like other brands have their own issues as well, but so far I've not read too many problems with Crucial MX200, SanDisk Ultra II, SanDisk Extreme Pro. Has the 850 evo so far been free of the problem that the 840 evo had?
I'd appreciate any comments and suggestions. I'd be interested to hear the competing perspectives of malventano and darkhaze too.
