Hello
Thinking of replacing my Drive with a SSD. Probably happen about the time Leap 42.2 comes out. Any problem with a couple xfs/Luks partitions on the SSD? Brands?
I just ordered a Crucial 525 MX 300 CT525MX300SSD1 SSD last week to install on an old laptop when 42.2 comes out. ### Crucial 525 MX 300 CT525MX300SSD1 Power Consumption Active Read/Write (Average in Watts): ? Note : The power consumption info appears to be a well garded secret. I can only find a reference to 0.075W Power Consumption Active Read/Write Idle (Watts) 0.075? Size: 525 Prix: 119,90 € at amazon.fr Prix/Go: 0.23 € Reliability (TBF) (Million hours): 1.5 Endurance (Total bytes written To): 220 Expected Lifetime writing 10 Go a day 10 : 61.7 years* Waranty 3 Years/160TBW Débit réel Mo/s hdparm -t /dev/sda ? - I have not installed it yet The following quote came off the Web somewhere: "The Crucial MX300 has an endurance of 220TBW, meaning you can write 220 terabytes of data to the drive before it becomes unreliable. To put this in perspective, if you write 50GB of data per day every day to the drive, it will take you some 12 years to wear it out. " [*] The following are my calculations Endurance : 220 To If I make 10GB hot writes per day (I have no idea but whatever), the expected drive life should be approximately (220*1024)/(10*365) = 61.7 years until total drive fault. ### I have also been using a Crucial M550 CT512M550SSD1 - 512 Go SSD on an old Thinkpad since Oct 2014. The machine only runsTumbleweed and it has a Luks encrypted ext4 data partition and I have never experienced any problems. The times I have re installed Tumbleweed, the installation process detects the encypted partition and just asks for the password / key. As a side note, the Crucial M550 CT512M550SSD1 SSD drive cost me almost twice as much € as the new CT525MX300SSD1 and its endurance (Total bytes written To) is only 70 To (compared to 220) so things have definitely improved ! ### I also love Samsung 850 PRO SSD and I have been using one in my main machine for the last 2 years with zero problems and regets. ### Samsung 850 PRO 1TB MZ-7KE1TOBW Power Consumption Active Read/Write (Average in Watts) 3.3W/3.0W Power Consumption Active Read/Write Idle (Watts) 0.4Watt Size: 1024 Prix: 540 € (on sale in Oct 2014); now 469 € Prix/Go: 0,53 € when I bought it (now 0,46 €) Reliability (TBF) (Million hours): 2.0 Endurance (Total bytes written To): 300 Expected Lifetime writing 10 Go a day 10 : 84,2 years* Waranty 10 Years/150TBW [*] The following are my calculations Endurance : 300 To # If I make 10GB hot writes per day (I have no idea but whatever), the expected drive life should be approximately (300*1024)/(10*365) = 84,2 years until total drive fault.
