Your results are atypical. It could be however the fault of the OS. Each bit in an SSD has a certain number of read/write cycles before it might fail. Some million of cycles. Back in the "old days" some OSes would write continously to the same place on the drive. For example you'd delete a file and then when a new file is created it would use the recently freed space. Today on modern computers with modern OSes systems are designed to spread the usage evenly all over the drive.
With a hard drive you WANT to bunch all your data so that itis physically close to minimized head movements but on an SSD you want the data dispersed Linux has a habit of creating and deleting tiny files like log files and such and making files in /tmp and would trash the SSD that was not wear leveled I think those days are over. New SSD have built-in wear leveling. https://en.wikipedia.org/wiki/Wear_leveling The question is about older or even antique Linux systems, do they know how to enable wear leveling on SSDs? I don't know when this was introduced to Linux. Fast forward to the year 2020... Today we don't use SSDs that are made to look like HDD and are put inside of a box with a SATA interface. That hack was a transitional technique for retrofitting SSD into older computers. The box is mostly filled with air and the SATA interface is dead-dog-slow compared to PCIe. A modern SSD comes on an M2 size card and plugs directly into the PCIe bus and does not even try to pretend it is a SATA Hard Drive. If you are buying new storage you want a PCIe interface M.2 forms factor SSD. https://en.wikipedia.org/wiki/M.2 On Thu, Jul 2, 2020 at 10:49 PM linden <l...@island.net> wrote: > Hello All, > > Any one here have real world experience with reliability of Solid > State Drives. > > I have not had much luck with them my self and am wondering is this > normal or am I the exception to the rule as if you believe the > advertising they should last almost for ever. > > First Experience around 2011 I bought 2 OCZ SSDs in Austria from 2 > different retailers and ran them in 2 different laptops used for office > work travel, a little software development and running industrial > automation service software.
