How To Optimize Ssd For Mac Os X

Posted on

When upgrading your Mac to the latest OSX version 10.11 El Capitan you may find that the operating system is somewhat sluggish, you can speed things up and optimize the software and hardware with a few simple things. 18 months back I bought my first SSD (120GB OCZ Vertex 2) for my (then) new iMac. I am using it as the primary disk, while I kept the original 1TB HDD as the secondary one.

Stay Away From Programs That Claim to “Defragment” Your Solid State Drive Solid-state drives. Modern operating systems like Windows 7 and Windows 8 won’t attempt to defragment SSDs. Good, up-to-date disk defragmentation software should refuse to defragment SSDs.

On a traditional mechanical drive, there’s a single head that moves over a spinning platter to read bits of files. If these files are broken up into multiple pieces in multiple places on the platter, the head will have to move around to read the file — that’s why fragmentation slows mechanical drive down and why defragmentation helps — the head doesn’t need to move as much. A solid-state drive doesn’t have a head or any other moving parts.

It doesn’t matter where the file is on the drive or how many pieces it’s in, it will take the same amount of time to read the file. Defragmentation is actually bad for a solid-state drive, as it will add additional wear. Solid-state drives have a limited amount of writes in them, and anything that results in many needless additional writes will decrease the life span of your drive. If you find an SSD optimization program that claims to defragment your SSD for maximum performance, stay away.

The same goes for using old defragmentation programs that aren’t aware of SSDs — avoid defragmenting your solid-state drive. The Verdict: Defragmentation is always bad, stay away! Some Programs Send TRIM Commands, But the OS Already Does This On a traditional magnetic drive, files you delete in your operating system aren’t immediately removed from disk — that’s.

It’s just as fast to write a new file over that old data, so there’s no reason to waste disk resources erasing any parts of the disk. That would just slow things down whenever you deleted a file.

On a solid-state drive, cells must be erased before writing to them. If you delete a file and the data is left lying around, it will take longer when you need to write to those cells as they’ll have to be erased first. The first solid-state drives suffered from this problem, so we invented TRIM to deal with it. When you delete a file on a modern solid-state drive using a modern operating system, the operating system sends a TRIM command to the drive, telling the drive that the file has been deleted.

The drive erases all cells containing the data, ensuring that writing to those cells is fast in the future — they’re empty and ready to go. TRIM support was added in Windows 7, so both Windows 7 and Windows 8 support TRIM. If you’re using Windows 7 and delete a file on an SSD, Windows will inform the SSD that the data is no longer needed and the SSD will erase the cells.

(The latest versions of other modern operating systems like Mac OS X and Linux also support TRIM.) Some SSD optimization programs claim that they’ll run TRIM on a schedule, informing the SSD of the areas the operating system thinks are empty and allowing the SSD to TRIM them, just in case the TRIM command didn’t work properly earlier. If you’re using an older operating system like Windows Vista or you were previously using such an operating system on the drive, it’s possible that deleted parts of files are still waiting around and waiting to be TRIMMed. Sending such TRIM hints once could theoretically help in such a situation, but it shouldn’t matter If you’re using Windows 7, which sends TRIM commands when files are deleted. On Windows 8, the Disk Defragmenter is now named the Optimize Drives tool. It will optimize disks by defragmenting them if they’re mechanical or sending TRIM hints to them if they’re SSDs.

This means that running another program that sends TRIM commands on a schedule is completely unnecessary on Windows 8, although even Windows 7 shouldn’t need this feature. The Verdict: Optimization utilities that send TRIM commands are harmless, but unnecessary. If you’re using an older version of Windows with an SSD, upgrade to Windows 7 or 8. Other Programs Consolidate Free Space We previously mentioned that cells on an SSD must be erased before they’re written to. This can be a problem — a single cell contains multiple writable pages.

If the drive needs to add additional data to a partially empty cell, the cell must be read, erased, and the modified data written back to the cell. If files are scattered all over your drive and every cell is partially empty, writing some data will result in a huge amount of read-erase-write operations, slowing down write operations. This shows up as. Solid-state drives have controllers that run firmware, which is a kind of low-level software. This firmware handles all the SSD’s low-level tasks, including consolidating free space when the drive reaches a certain level of capacity, ensuring that there are plenty of empty cells instead of many partially empty cells.

Some optimization programs claim they’ll consolidate free space by moving data around on your solid-state drive with an intelligent algorithm. In a world where this was possible, the results of this would vary from drive to drive.
