Apenas um palpite, mas o sistema operacional pode estar atualizando os metadados de tempo de acesso em arquivos / pastas quando você os visualiza. Tente montar o pacote somente leitura para evitar isso.
- EDIT Tente desativar as atualizações de horário e a indexação do Spotlight. Este tutorial é destinado a unidades SSD, mas não vejo razão para que elas não funcionem para você.
Disable file access time tracking
Normally the Mac will keep track of the last time any file was accessed. This contributes to the wear on the SSD drive, so it is helpful to disable it.
sudo touch /Library/LaunchDaemons/com.noatime.root.plist
Edit the file and paste the following:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.noatime.root</string>
<key>ProgramArguments</key>
<array>
<string>mount</string>
<string>-uwo</string>
<string>noatime</string>
<string>/</string>
</array>
<key>RunAtLoad</key>
<true/>
</dict>
</plist>
Reboot and confirm the setting with:
mount | grep noatime
/dev/disk0s2 on / (hfs, local, journaled, noatime)
Adjust Spotlight settings
Spotlight is the Mac’s indexer and search tool. While a lot of people just disable this service (sudo mdutil -a -i off), I need Spotlight because Outlook 2011 uses it for searching my Outlook data.
To adjust this setting, go to System Preferences…Spotlight…Privacy. If you exclude directories that change frequently, you’ll save wear on your SSD. For example, I excluded:
/Library/Caches
~/Library/Caches
/Library/Application Support/Riverbed/Steelhead Mobile/datastore
~/Downloads
~/Documents/Parallels (where I store my VMs)
