But here you have the Market Leader, the pretty much uncontested top of the Benchmark-Winner's heap: Samsung's Recent EVO Series - the SATA III 860 EVO as your optimal choice for a MacBook laptop or Mac desktop SSD upgrade - or for use in a Mac compatible external Thunderbolt or USB 3.0/3.1 DIY backup drive you can assemble in minutes.
There are also mSATA (below) and M.2 (above) form-factor 860 EVO SSD blades for those who want to build a compact 10Gbps USB 3.1 Gen2 USB-C or 5Gbps USB 3.0 external backup drive for MacOS, TimeMachine or other Mac file storage needs. All pretty much MAX-OUT the full bandwidth of 6Gbps SATA III interface. For better Read/Write performance you have to make the leap to PCIe interface NVMe drives featured elsewhere on this site.
For the extra 10 or 20 bucks of the Samsung drives over other brands, you'll get peak Read / Write speeds, mature firmware, highly efficient mapping and management of memory cells and a long 5 year warranty to reassure buyers they made the best choice. Simply stated, forget the rest, buy the best. You won't regret it.
Also note the Vertex is the only one with (sadly, Windows PC required) firmware upgrade jumper - and that there's no 30GB Apex model because of it'sdual JMicron controller design for an INTERNAL RAID 0 config - meaning it's basically 2 30GB banks of MLC NAND flash teamed up to provide the 60GB of capacity.
Download MACTRACKER - A great reference of Apple system specs to get specific SATA bus speed info for specific models. Apple started using SATA II in Late 2007 only on very select Macs. As of this writing, only the recently revised 2009 'Classic' white MacBook still uses SATA I - and only the newest 5-USB-Port Mac Mini of 2009 finally added SATA II support. MacTracker will also point out the fine distinctions of when and exactly which models made the switch from ATA drive interfaces to SATA I.
It's important to note that the quoted transfer rates of SSD's in Press Releases, Product Listings, or even on this site are PEAK numbers only on SEQUENTIAL types of read/writes - often more theoretical than real world throughput the average user will experience. The RANDOM read/write numbers are markedly lower - especially random writes. Oh but what do you care? Unless you absolutely went out of your way to research and upgrade your existing mechanical hard drive to top of the line models - ANY current-generation SSD is going to feel faster than what your Mac came with.
Be aware, often benchmarking articles and SSD reviews are deceiving: the Tweak Geeks often pit the latest top of the line SSD they're testing against the absolutely fastest platter drives known to man such as Samsung's F1, WD's Velociraptor, or Seagate's Barracuda ultra-high RPM drives that the majority of us do NOT have installed in our computers. That doesn't really show the difference an SSD can make over the stock, often Middle-Of-The-Road performing drive Apple included in your Macintosh.
