Review on OWC iMac 2012 In-Line Digital Thermal Sensor HDD Upgrade Cable (Model: OWCDIDIMACHDD12) by Leroy Wolfe

I bought it almost a year and a half ago because I was afraid to install. I finally did it about a month ago and am happy with the results. I have a late 2013 27" iMac with an i5 processor that ran like a dog at 5400 rpm due to the poor performance of a 1TB Seagate hard drive (I understand Apple thin is expensive - heat) . I used the OWC kit to replace it with a 2TB 3.5" Seagate SATA 6Gb/s Desktop SSD (ST2000DX001) (Legacy). While not as fast as a real SSD, it's a cheaper solution (they're currently just over $100 on Revain) and there's a noticeable increase in overall performance. My kit had everything shown online, a video , which can be seen on the OWC YouTube channel. They have a new version they just released on 02/03/2017. I followed OWC's instructions exactly and the video played on my PC while I disassembled it. Regarding the spare band, I wish they had provided a lot more in the kit as I had enough after making a few mistakes. The method I eventually came up with was to fold the backing along the strip of tape and then use that as a guide to line it up with the edge of the iMac case. I verified that this is the same brand and type of duct tape that the Apple Store geniuses use when they take apart your iMac. My only other recommendation is to be very careful with the screen. The glass is so large that it may bend when assembling the device. After putting the glass back on, it now looks like it was never taken apart. I then did a clean install of macOS Sierra and connected my old drive to an Anker USB 3.0 to SATA 3ft to 2.5"/3.5" adapter cable. Hard drive Hard drive and solid state drive, including power supply and migration assistant to transfer my files and settings to the new hard drive. After a month everything runs faster and the computer is actually back in less than a minute after a restart. Some ephemeral things. When I checked the SSD I went to the OWC website and chatted. I asked if I need to use a temperature sensor with an SSD that doesn't get as hot as a comparable hard drive. Chat said to use it, so I did a bit of digging and confirmed that the circuitry included in the black connector is not only a temperature sensor, but also contains EPROMS that tell the iMac what drive you're using. is an Apple certified device. New drives now include firmware to work around this problem, but my wife bought me a SHHD for Christmas 2014. I would still need to use a sensor since the new drive is mechanical, but if you bought a pre 2015 SSD that you want to replace, use a temperature sensor. Also, this version of 27-inch iMac (iMac14.2) doesn't have an eMMC slot on the motherboard, so I couldn't get a 64GB eMMC drive to upgrade the Fusion Drive, for example. On the plus side, Seagate now sells SHHDs with the same SSD size but uses a different read/write scheme called Tiled Magnetic Recording, or SMR. This allows for thinner platters and faster read/write times over time. Seagate fans, Western Digital is releasing what they call a dual drive, which is a standard hard drive and solid-state drive in a sandwich, but it's difficult to install on a Mac. the same capacity. Seagate's solution just works and makes the Mac faster over time. In other words, your fifth boot is faster than your first boot.
