It's genuinely innovative, and elegantly designed as always, but also frustratingly convinced of its own infallibility, and - especially for those of us in post-Brexit Britain - jaw-droppingly expensive.Ībove all else, though, this update to the MacBook Pro range is long overdue, with only modest speedbumps in recent years to placate Apple's demanding professional users - who, let's not forget, kept the company afloat in the lean years before the advent of the all-conquering iPhone. The new 15-inch MacBook Pro is a quintessential Apple product. If you see inaccuracies in our content, please report the mistake via this form.

The controller might fail sooner but the failure rate of an SSD in RAID0 should still be less than half of a standard hard drive. In terms of raw write endurance, SSDs have been tested to last into the hundreds of TBs.Įven for someone using a drive for large video files with 100GB of writes every day, they shouldn't get an error (correctable) for roughly 3 years and a drive failure for about 10 years from the memory itself. The consumer only needs to be concerned with how long the overall product will last and the one above has a 3 year warranty. Sometimes the use of RAID is due to cost where manufacturers can source e.g 2x 128GB components for less than 1x 256GB. The performance gain there isn't all that much with RAID0 but using JBOD where you don't write to both at once still means you have two drives, each of which can fail. Other drives might use RAID0 if there's a bandwidth limit somewhere. Mechanical drives can have quite high failure rates and being mechanical, they will always wear out and be subject to environmental conditions.Īpple has no reason to put two separate SSDs internally as they can get enough bandwidth to a single drive and put all the NAND chips in parallel. Your issue with RAID0 is that by having two or more controllers, it increases the chances that one will fail but less data is being written to each drive so it's not an issue either way. Writing to the chips in parallel increases their lifespan. The SSD will write to each NAND chip in parallel, which is how RAID0 works but it's not two SSDs in RAID0. It's a custom one with Sandisk NAND chips and Apple's own controller chips.
