Install the latest OS on the internal drive prior to pulling it to make sure all the firmware is updated. After testing it, then do the internal swap.

Piece of advice, if you decide to swap the internal drive, either one, I would set it up externally first and make sure it boots up and it working correctly. Probably not worth it, but I am thinking of doing this on one of my Late 2012 or Late 2013 iMacs just for fun. Obviously more complex, but probably still cheaper than doing a single external TB3 NVMe drive, while still being faster. I could be wrong, but I think there is no TRIM support. I think this would be the fastest possible boot drive on the Late 2013 iMac, probably 1000MBps+ speeds. Both drives made into a SW stripping RAID. Internal RAID0 - Replacing both the blade SSD and the HDD swap with a SATA SSD. More expensive than replacing the HDD with a SATA SSD, but same speeds. Biggest downside is removing the glass/display, cleaning up, and using the adhesive strips to put it back together.īlade SSD swap/adapter - More complex install due to removing the logic board. Nice to get that hot running HDD out of the Mac. HDD to SATA SSD Swap - Cheapest internal option, speeds over 600Mbps, TRIM support. Probably not worth it due to complexity and cost. I have never tried this, but would think speeds of 700MBps would be realitistic. The biggest issue with this is that you need to have a TB3 dock with 10Gbps USB ports, and also a bidirectional adapter to connect it to your Mac. USB3.2x1 - 10Gbps link speed, easy to find. Probably not worth it due to complexity and cost, unless you need that super fast speed. NVMe drives are falling in price, but between the drive, the bidirectional adapter, and maybe something to power the drive, this could be an expensive option. Depending on the set up, could require a TB3 dock to power the drive. TB3 - A TB3 NVMe drive is the fastest single non-RAID drive you can get for you Mac.

Just like the TB1, probably not worth it do to price. They tend to be pricey, but you could see speeds close to 800MBps on the NVMe TB2 drives that I have researched before. You can also find some NVMe and AHCI TB2 SSD enclosures. TB2 - Basically the same as the TB1 drive on your iMac if you use a SATA SSD. Probably not worth it, as they are expensive. Hard to find these drives, and eBay would probably be the best way to source them. TB1 - A SATA SSD would be about the same speed as a USB3 SSD, but you get TRIM support. Recommended for most people unless higher speeds is required. You can get a SSD external drive like the Samsung T5, or get a cheaper SATA SSD with an enclosure or USB3 SATA cable adapter. SD Card - IIRC, I think it is limited to 5000Mbps link speed, and you would only see those speeds with a high speed SD card, which is very expensive. You can run it like that for a while, and if you decide to install it internally, you could always do that later.Ĭlick to expand.Like I said, there are plenty of options for the Late 2013 iMac, all with pros and cons, here are the external options: Either an enclosure, or just a SATA adapter cable, both could be purchased for around $10. You don’t need to get Thunderbolt, you could just run it using USB. A couple weeks ago someone had a similar question on the forum, and I found a name brand 2TB 2.5 inch SDD for $128 on NewEgg. You could get internal SSDs for really cheap right now. I got a 2 TB 2.5 inch HDD that I am currently booting from a Thunderbolt enclosure, but I plan on installing it internally soon so I can use Boot Camp. I suspected based off of the description, it was just a bad HDD, and it paid off as I was right. I got it for really cheap on eBay, because they had it listed for parts. It has a 2 or 3 TB HDD that is currently dead. I have a linch iMac, that was a BTO model with the best of everything, with exception of the storage. You could run an external drive, for now, and install it later if you want.
