Only when first started? or when starting from Sleep mode? Note that. “Three minutes from cold-start before you can open any application” ? that’s specific. that one would check up on now & then even if things SEEMED to be Okay.įirstly, IDENTIFY THE PROBLEM so you know what it is you are trying to fix, do not do as I do & rush ahead assuming you know what to do! “Slow Start Up?” Be specific. So you may have any of: MacBook, MacBook Pro, MacBook Air, iMac, etc etc. This article is not about iPod, iPads, etc… I like to run diagnostics BEFORE attempting any fix so I have something to compare the results to objectively. clearly define “Strange” before applying remedies. You may just want a quick checkup or may be it’s behaving strangely and needs fixing. As already mentioned, SSDs are much more reliable than HDDs, but the one thing that I find dramatically shortens their lifespan is overheating.We assume you have an Intel Apple MAC Computer Life Percentage Used and Data Units Written will increase over time as the drive is used, but Media and Data Integrity Errors and Critical Composite Temperature Time problems are signs of immediate problems.Ĭritical Composite Temperature Time also highlights how keeping the SSD cool can help prolong its life. These are the ones I find worth keeping an eye on. If everything isn't green, you need to drop everything and get your drive replaced as soon as possible. Keep up with your backups and you should be in good shape. The four that I like to keep an eye on are: In addition to how much data has been written to the disk, this gives access to more than a dozen other parameters.
Typically, a 250GB SSD will have a rating of 60 and 150TBW, which means that even at the lowest end of the rating to exceed this number in a year, you'd have to be writing more than 100GB of data onto that 250GB drive EVERY DAY.Ī tool I use for keeping an eye on my storage drive is DriveDX. It's a feel-good number that storage manufacturers come up with to measure storage life (think MTTB or Mean Time Before Failure for hard drives). One key metric of SSD wear is measured in TBW, or TeraBytes Written. So, in addition to having a backup or two (you should always have at least two backups of your important data), it's a good idea to keep an eye on your Mac's storage drive. The downsides of SSDs compared to HDDs is that you get little to no warning when they are starting to malfunction, and when they die, it's generally permanent. SSDs (Solid State Drives) are much more reliable than HDDs (Hard Disk Drives), but that doesn't make them invulnerable. Here are the best options, sorted by price from low to high.
