Comment Hmmm, SSD not always best (Score 0) 405
- the throughput numbers of SSD's are bogus since they are calculated using highly compressible data; HDD performance doesn't depend on compressing data and won't change just because you're writing out a binary file.
- SSD's on notebooks and smaller may make sense because of the lower power and shock resistance
- SSD's on desktops/workstations don't make nearly as much sense. I have an SSD in on of my machines. The machine also has 4 fairly old HDDs striped in RAID 0 (yes with frequent backups). The HDD's blow the socks off the SSD. If I put more modern drives in the RAID array the disparity would be even worse. Yes the HDD's use more power but the point of the desktop is performance.
- seems to me I remember that SSD's are not recommended for paging - although right now I can't remember why or where I read it so YMMV. And yes, many systems don't page.
- some people say it isn't throughput that counts it's IOP's - well again a good RAID system isn't too shabby at that either but even if SSD's were to always win out in IOP's the question of whether that matters really depends on what you are doing with your system. For example when I want that 2GBB stack of images to load I want it to load NOW and throughput is what matters. The same with compiling large sources, etc.
