To be fair, it was utilized primarily as cache for the hard drive. Though it was okay in 2015, the 24GB NVMe SSD that came out of my iMac was slow by today’s standards, not to mention drastically undersized. Once you have the drive installed and are ready to test it, I recommend that you only do the bare minimum of reassembly (minimal screws, leave the display untaped, no speakers, etc.) so that you don’t have to repeat the entire disassembly again should the something be amiss with the drive or the procedure otherwise doesn’t work. If you’re brave, you can deepen the adapter’s and SSD’s indentations a bit with a round file and much care. This did unfortunately induce a bit of a bow in the SSD, but shouldn’t be a problem. Remember how I brought up the fit issue with the Sinetech adapter? I was able to screw the assembly in place by tilting the screw with its tip just in the hole, then pressing it towards the assembly. And darn if Apple’s AIO’s don’t look better empty than others do assembled.
Just to prove I actually disassembled it, as well as ignored my own advice about a large workspace. These are also slightly different from the others with a raised secondary flange beneath the actual screw head.Ī completely useless picture of what a late 2015 27-inch iMac looks like with the components removed. There are upward-facing screws behind the fan that are easy to forget. You must press these to enable removal and the large cable requires a fair amount of force. The webcam and primary display cables have flip-up locks, don’t just yank on them.īoth large cables connecting the power supply with the motherboard have latches. There’s a captive screw behind the motherboard that you access through a hole in said board. It’s simple, but a few pain points:Ī post for the power supply is also a screw securing the motherboard. You’ll find the NVMe SSD on the back of the latter, secured by one screw. I already had a bunch and they’re not all cheapos.Īfter that, the whole deal consists of delicately unplugging a few cables, undoing quite a few Torx screws (you’ll obviously need torx drivers), then removing the speakers, power supply (don’t touch the bare solder joints on the back), and logic board. While 25 cents per gigabyte isn’t bad-the Feather drive turned out to be a good all-around performer-I was enamored with the idea of using a less expensive M.2 2280 drive.
It’s a good performer and the company is accessible for support and tips. The Fledging M13 was the most affordable upgrade SSD I found from a vendor in the U.S. The company armed me with a number of relevant tips, and sent me a 512GB M13 Feather SSD kit with macOS High Sierra pre-installed. Finally, I stumbled on a company with an office in Birmingham, Alabama called Fledging, whose Feather drives run around 25 cents per gigabyte and are available in up to 2TB of capacity. That’s better, but they were from unfamiliar companies I was unable to chat with. Perusing further, I found Apple-compatible SSDs for around 30 cents per gigabyte. OWC’s compatible drives on Newegg were 40 cents per gigabyte, and Apple’s on Amazon were an incredible $1 a gigabyte! This is 2019: standard M.2 2280 NVMe SSDs start at 15 cents per gigabyte! A huge issue is that Apple uses proprietary connectors. You do the math.As I intimated, there was never any question that the NVMe SSD could be upgraded, just whether it could be done for a reasonable price. Right now I myself use a 4-th SSD Samsung 840 without trim enabled. It's been 3 moths since, and they haven't returned since. After replacing them i hadn't turned on trim anymore. They both came back to me in a month and a half with a fired SSD. I just recently had 2 customers with a macbook that asked me to upgrade to an SSD. I can't really prove it, I my self, am a guy that needs hard proof, but this isn't a coincidence.
Its not the laptop ( MacBook Pro 17" Mid 2010 I5, nVidia 330M ). If it were a motherboard problem, they would have found it. As I was saying, I work in a service, I have tech guys which are very good at what they do. As soon as I turn on trim, with in a month or so, my SSD dies. Cant really explain it, not an OS X expert. So I deal with a lot of laptops on a daily basis. Im at my 4-th right now ( thx God for warranty ).
I fried 3 SSD Samsung 840 ( not the pro version ). The problem with the OS X Trim command it that it kills your SSD.
