Thanks for all you do! Love my MPG Pro Workstation w/24 GB.
With my MPG I've been running for several years, Drive Genius 3 shows my Aperture Library has over 75K fragments (4TB Master is RAID-0 , 75% full).
Should I Defrag my Master? Can't seem to find much about Defrag for RAID/Aperture.
Aperture seems to run OK, just wondering if performance would improve/beneficial for program
Thank you - love all your research & info.
MPG: Defragmenting a volume might or might not help; it depends on the access patterns. And it takes time: how much will you save (net)?
General recommendation for Lightroom or Aperture
My general recommendation for Lightroom or Aperture or similar is to:
- Store original large image files on a large volume such as a 4TB hard drive or similar (and/or a 2-drive RAID-0 stripe).
- Place the catalog/library on a separate high performance PCIe SSD or similar.
That’s because catalog/library operations benefit hugely from an SSD, but the original images (particularly raw format images) are generally not involved in any way that impacts speed of operation.
Upgrading those drives — strong reasons
In this particular case, drives are notably faster today than in 2010.
More benefit would accrue by replacing the 3-year-old 2TB drives with a fresh pair of current fast 3TB hard drives or fast 4TB hard drives, which are up to 40% faster than the circa-2010 2TB drives for sequential transfer speed. That’s a big difference in responsiveness.
And the 3TB drives are not particularly expensive. While I prefer 4TB drives, it all depends on how much stuff you have to store. Ideally, aim for using only 50% of capacity to keep transfer rates at high speed.
Note well that drives slow down as they fill up, so Harris W is working off the slowest portion of the drives! See Why You Need More Space Than You You Need; Harris W is at present using a sort of anti-optimization. By upgrading to larger and faster drives, actual performance increases for sequential transfers might be on the order of 70% or so once the capacity usage influence is accounted for. Not all of that will translate to user experience; much of what Aperture or Lightroom do is CPU-limited.
Finally, I get nervous about having my data on 3-year-old hard drives in any case, depending on usage time. Turn those existing drives into external backups.
