We understand that there are several 3rd party repair stores that claim to have authentic Apple computer parts, used Mac parts, MacBook Pro parts, and more.The Mini I am working on is the middle-level model with a 1TB HDD. See All Apple Display Cable Adapters. 922-6675 Apple DVI to VGA Adapter for Mac Mini & Other Macs.IMac Memory for Models 5.1 and 6.1. Generation 1: MacBook Air (Late 2010 – Mid 2011)The iMac Model 7,1 takes DDR-667Mhz RAM and has a system maximum of 6GB with the installation of one 2GB module and one 4GB module. As far as I know all the 2014 Mini logic boards have this socket.Mac Pro 5,1 - Introduced in June 2012. If you are, it’s time to get up to speed!For the Mac Pro, Mac mini, and MacBook Air series, the models below are the oldest ones that still qualify for a macOS Sierra upgrade. If you’re into vintage computers and you think patience is a virtue that can only be honed by waiting for programs to respond, maybe you’re still rocking a drive with a PATA interface. I had to use the Mac Mini tool hooked into a hole in the grill as a lever to lift it up and in towards the lip of the rim it was sitting on.Every hard drive or solid state drive you’ve used in the past ten years is likely to have used either a SATA interface, or more recently a PCI Express interface. As for the grill, it would not line up with the screw holes. 5AEven with the logic board pushed out, I found it difficult to line up the screws on the hard drive and get it seated properly.
![]() Like the SATA bus standard, PCIe has undergone multiple revisions over the years and is still evolving at breakneck speeds. It’s no wonder that manufacturers moved towards PCIe technology for their bandwidth hungry SSDs. In short, SATA just wasn’t made for solid state drives.Peripheral Component Interconnect Express (PCIe) is a computer bus standard with incredibly high bandwidth potential, and is the fastest bus option that most computers have available. And even if you’re using a SATA III interface, you’re still probably limiting your SSD. But as it applies to SSDs, if you’re not using a SATA III connection, it’s safe to assume you’re limiting the potential of your drive. And communicated data based on the speeds and needs of those devices. That 20% overhead eats into the potential bandwidth of an interface, resulting real world bandwidth that’s 20% lower.PCIe 3.0 introduced the much more efficient 128b/130b encoding, resulting in only only ~1.5% overhead to eat into the potential bandwidth.Advanced Host Controller Interface (AHCI) was originally created when storage devices still used spinning magnetic disks to store data. In other words, 2 of the 10 bits are just overhead necessary to transmit the rest of the data. PCIe 1.0 and 2.0 both use 8b/10b encoding to transmit data (the same as SATA), meaning that for every 8 bits of data sent, the data is sent via a 10 bit line code. Most PCIe SSDs will have either 2, or more recently, 4 channels of throughput.In 2011 the PCIe 3.0 revision was released, and finally brings more to the table than just the ability to add additional channels. Those speeds may sound a bit slower than SATA III, but PCIe has the advantage of utilizing multiple channels of throughput to accommodate the needs of the connected peripheral.Two channels of throughput (~1GB/s) not enough for you? Double the number of channels to four and you’ll realize double the data transfer rates, if the connected device can make use of it that is. PCIe bandwidth can be scaled up to 16 and even 32 lanes for a single device, but that’s uncommon in SSDs and primarily reserved for devices like graphics cards which have larger data transfer requirements. ![]() Both drives performed up to Apple’s advertised specs, mind you, but MacBook Air customers were subject to an SSD lottery, with Samsung drives performing reads and writes at ~1.5x-2.0x the speed of their Toshiba counterparts. This “Generation 1” drive utilized a proprietary 6+12 pin connector, but still used an mSATA III interface limited to 6Gb/s the same limitation as the other product lines released during this period.Both Samsung and Toshiba manufactured Apple’s Generation 1 SSDs, but rather notoriously, the Toshiba drives performed significantly worse than their Samsung counterparts. Rather than use a 2.5″ SATA SSD as seen in the rest of Apple’s product lines, or even the 1.8″ SSD found in the original MacBook Air, Apple switched to an even thinner, custom drive. Comparison of proprietary SSD connectors.Generation 1: MacBook Air (Late 2010 - Mid 2011)For the Late 2010 and Mid 2011 releases of the MacBook Air 11″ (Model A1370) and MacBook Air 13″ (Model A1369), Apple’s desire to shave down the height of the already thin original MacBook Air necessitated a switch to a thinner drive. Can you install office for mac 2011 onto multiple computersThe operating system displays the two drives as a single drive to the user, but behind the scenes optimizes file storage so that files requiring more frequent access and files that see the most benefits from quick read times are stored on the SSD, while the majority of the files are stored on the HDD. Apple’s Fusion Drive pairs a larger capacity traditional hard drive with a smaller capacity solid state drive, offering much of the performance benefits of an SSD, but in a more cost-effective package. 2A SSDs used by these MacBook Pro laptops were offered in 128GB, 256GB, 512GB, and 768GB capacities, and manufactured again by Samsung, but also by SanDisk.Both the 13″ and 15″ MacBook Pro laptops use the same drives, and either MBP can have any of the four SSD capacities installed.The Late 2012 and Early 2013 iMacs had a rather different arrangement, with a traditional 3.5″ SATA III HDD standard, but the Late 2012 release also unveiled the Fusion Drive.
