Throughput is bottlenecked at the flash an SSD is only as fast as it can write to the flash memory. With the TRIM command, there is less data to move during GC and the drive runs faster.

Less data is re-written and more free space is available during GC (more space to write equals fewer writes needed) A 3rd party free app called Trim Enabler will enable OS X's TRIM feature on 3rd party SSD drives. TRIM aids in the reduction of write amplificationand some improved performance. In OS X Mavericks, that bug has been fixed and clicking IGNORE will change the RED lettering to black and let you manage each drive separately. You would have to use Terminal (diskutil) to manage them. The IGNORE will do nothing and won't let you individually manage each drive. In case you want to use the SSD and HDD separately, know that in Disk Utility from the Recovery HD in OS X Mountain Lion there's a bug with the IGNORE/FIX buttons.

So, do a full system back up before creating a Fusion drive. Clicking FIX will erase both drives and automatically create a Fusion drive. You will see both drives marked in RED lettering and a popup will display giving you an option IGNORE or FIX. You can create your Fusion drive by restarting into the Recovery HD ( Command+R). You don't need to use Terminal commands with OS X Mountain Lion 10.8.2 and above (which includes OS X Mavericks). am I missing something?Ĭan someone temper my enthusiasm before I bite off more than I can chew with a perfectly good 6-month-old Mac mini?

I always back-up to Time Machine so am not overly concerned about doubling the risk of data loss with a Fusion set-up.
Better still, i t was mentioned, in another thread, that Disk Utility in later Mac Minis automatically set-up two installed drives as a single Fusion Drive volume, so I would not even have to delve into the dark arts of the Terminal to set it up, just pick-up a disk doubler kit from iFixit or OWC, drop in the SSD, load OS 10.9 onto the SSD, boot into Disk Utilities, select 'Repair Disk' then go and make a cup of tea!Įven though I might have to forfeit my remaining 6 months of Applecare, it seems like a compelling way to vastly improve my Mac mini's disappointingly sluggish performance. The clunky 5,400rpm HDD that it came with is laboriously slow and the opportuity to add a 256GB SSD (probably a Sandisk?), for a lot less than the incremental price hike of having specified a 128GB Fusion Drive in the first place, seems very tempting. With the falling prices of SSDs, I am fascinated by the prospect of adding one to my Late-2012 quad-core i7 Mac mini and set it up as a single Fusion Drive volume with the existing 1TB HDD.
