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. In 2011 the PCIe 3.0 revision was released, and finally brings more to the table than just the ability to add additional channels. Most PCIe SSDs will have either 2, or more recently, 4 channels of throughput. Two channels of throughput (~1GB/s) not enough for you? Double the number of channels to four and youвЂ™ll realize double the data transfer rates, if the connected device can make use of it that is.В PCIe bandwidth can be scaled up to 16 and even 32 lanes for a single device, but thatвЂ™s uncommon in SSDs and primarily reserved for devices like graphics cards which have larger data transfer requirements. 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. PCIe 2.0 (which is likely to be the most common PCIe revision found inside in-use computers) maxes out at ~500MB/s with a single channel of throughput. Like the SATA bus standard, PCIe has undergone multiple revisions over the years and is still evolving at breakneck speeds. ItвЂ™s no wonder that manufacturers moved towards PCIe technology for their bandwidth hungry SSDs.

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. In short, SATA just wasnвЂ™t made for solid state drives. And even if youвЂ™re using a SATA III interface, youвЂ™re still probably limiting your SSD. But as it applies to SSDs, if youвЂ™re not using a SATA III connection, itвЂ™s safe to assume youвЂ™re limiting the potential of your drive. This can cause some confusion in the event that you connect a hard drive that supports the SATA III standard into a SATA II connector, creating a bottleneck at the SATA II interface that will limit the potential bandwidth of the drive. The SATA standard has now undergone three major revisions, resulting in connectors that are identical in appearance (hurray for backwards compatibility), but with bandwidth doubling each time. The SATA standardвЂ™s been in use for many years and is still the most prevalent interface for connecting internal storage drives. SATA (Serial Advanced Technology Attachment) refers to the technology standard for connecting hard drives, solid state drive, and optical drives to the computerвЂ™s motherboard. Luckily, advances in host interfaces invariably stay ahead of the pace of drive technologies, always allowing room to push speeds a bit farther. If you are, itвЂ™s time to get up to speed!Д®ver faster drive technology, brought about by faster spinning disks, increased cache, advances in controller architecture, and a host of other factors keeps pushing the host interface to become the bottleneck for read and write speeds. If youвЂ™re into vintage computers and you think patience is a virtue that can only be honed by waiting for programs to respond, maybe youвЂ™re still rocking a drive with a PATA interface.

5AД®very hard drive or solid state drive youвЂ™ve used in the past ten years is likely to have used either a SATA interface, or more recently a PCI Express interface. Generation 1: MacBook Air (Late 2010 вЂ“ Mid 2011).

What make and model is the SSD? The only SSDs that seem fully Mac-friendly are the Crucial MX series (skip the BX series) or Other World Computing SSDs.

CCC insures all needed boot files plus the important recovery and diagnostic functions are properly created on the new volume. I used Carbon Copy Cloner ( ) to clone my 2012 MBP's HD to a new SSD. If the SSD is to be either an internal of external boot volume, you do not copy the old drive to the new one, you clone it. If setting up an external boot volume, the USB enclosure must be USB3 and the SSD inside must be rated SATA 6GB/sec to see maximum benefit. You do not need a USB cable for internal installation, but should replace the internal hard drive cable when changing the internal boot drive. Are you wanting the SSD to be an internal boot volume, an external boot volume, or ether internal or external non-bootable storage? Those options can make a different in how we recommend you proceed.
