![]() 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. ![]() NVMe was created specifically to work with SSDs, reducing the latency and allowing for larger amounts of data to be transferred at a single time, making better use of modern multi-core processors. AHCI was versatile enough to work with SSDs while SSDs were still in their infancy, but it’s been a hindrance to transfer rates for a few years now.Enter NVMe, or Non-Volatile Memory Express. 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. Ssd For 2012 Book Air Full Potential ThroughputThis “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. And unlike M.2 pin arrangements, Apple’s connectors were never given distinguishing names, so from this point on I’ll just refer to the connectors by their pin arrangements as described in the image below. With the 2010 MacBook Air, Apple began a new trend of developing proprietary connectors and form factors that eventually pervaded the entire Apple lineup and ushered in an era of drives that, while easily replaceable, were not so easy to find.Many people incorrectly assume the connectors are one of the M.2 variants found in many PCs, but to date, Apple has still never used a standard M.2 connector. By the time the PCIe 3.0 revision came out, NVMe became essential to reach the full potential throughput of the drives.When Apple released their first “blade” solid state drive in the Late 2010 release of the MacBook Air, they still used established mSATA interface technology, but ditched the traditional SATA and mSATA form factors found in most laptops at that time, instead opting for a custom connector that’s never been used by another manufacturer before or since. My passport for mac 1tb softwareThe 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. Apple seems to have learned from this oversight and later generations of SSDs never again saw such a large distinction between the drives of different manufacturers.With the release of the first MacBook Pro with “Retina” screen, Apple began including SSDs standard in the MacBook Pro line, and in fact the only storage device interface is the single 7+17 Pin SSD connector.
