The advice, 'You should never use more than 70% of the total capacity to avoid performance issues.' is all very well but if taken literally means starting a new backup as I'm not aware of any way of reducing the size of a TM backup.

The RDHDs are always fairly warm/hot to touch but the SSDs are actually cold! Both of the SSDs, being small, are fixed side by side onto the back of the iMac metal stand with a cable tie, which hopefully will act as a heat sink in the event that they do ever get hot?īefore I got the SSDs I looked at several makes and most appeared to recommend them for TM use without any concerns or warnings about capacity problems. My old Intel iMac still has a pair of RDHDs attached for the same purposes. When I got my new M1 iMac I also bought a pair of Seagate SSDs. Example:Īn awful lot to digest, and understand, in all of this information! Somewhere around $100 just for the case with no drive in it. In fact, when you find these rare case kits, they will be surprisingly expensive. To my knowledge, this doesn’t describe any case kits from OWC, a favorite supplier among Mac users. Note that what you are looking for is a case kit that includes a very robust power supply, and a fan. There are external case kits, and I’ve considered building my own high quality external SSD by using only the best components. That will likely come to haunt you at some point. Unless you purchase an extremely well made one (which will noticeably be priced to reflect this), like many Intel models, you can bet that your SSD has had some corners cut to be reasonably priced.

Lots of folks think of SSD’s as being magical devices that are always fast and which are ultra reliable. But they tend to slow down early in their lifespan and have no over-provisioning whatsoever.

Note that Samsung’s SSD’s are very popular because of their price and initial performance.

They may do some TRIM-like things based in their own ROM, but it’s not like having a full implementation of TRIM enabled. I don’t know of any external SSD’s that use Apple’s implementation of TRIM. You can get a huge SSD to work around the problem of your Time Machine drive filling up, but the price of huge SSD’s is silly compared to similarly large RDHD’s. Some random thoughts regarding the above, in response to things that I've heard others say. Why solid-state drive (SSD) performance slows down as it becomes full “When you’re getting close to the 70% threshold, you should consider upgrading your computer’s SSD with a larger drive.” To avoid performance issues, you should never use more than 70% of its total capacity. "The rule of thumb to keep SSDs at top speeds is to never completely fill them up. So, after that, your TM backup will become molasses slow, and even possibly fail. The problem is that SSD’s start drastically slowing down when they get about 70% full. Once your hard drive is filled up, TM is designed to started deleting the oldest files to make room for new files. TM works by keeping versions of all of your past files, quickly filling up your hard drive. This is especially a problem when backing up using TM, because TM backups can really exercise a hard drive.īut that isn’t the only problem SSD’s have when used for Time Machine backups. "SSDs that run too hot will slow down and can cause data loss or complete failure of the drive."
