Unconventional SSDs: PCI Express Mini Card (Mini PCI-E)

mSATA SSDs like this Toshiba model reuse reserved Mini-PCIe pins for SATA connections

With Apple almost certain to introduce a new MacBook Air, questions have turned to the specifics of the hardware to be used. A leaked pre-production photo features an odd memory configuration (not to mention four batteries), a device I immediately recognized as an SSD-on-a-stick. With this high-profile introduction of a new SSD stick form, I thought it was time to cover these unconventional new storage formats.

Apple’s Unconventional New MacBook Air SSD

The new MacBook Air includes tiny SSD and AirPort cards

Apple updated the ultra-slim don’t-call-it-a-netbook MacBook Air this week. Along with a wimpy out-of-date CPU, the new Air features all-SSD storage of an entirely new and apparently proprietary type. Let’s take a look and see what we can see.

Toshiba Offers “Blade” SSDs (Like Apple’s MacBook Air)

It won't be long before other manufacturers adopt the new SATA SSD form factor introduced in the MacBook Air

More information about the unconventional SSD used in Apple’s new MacBook Air. As I discussed in my previous coverage of this new flash form factor, it resembles a PCI Express Mini Card but is much smaller. Toshiba has now proved my speculation that the device uses SATA signals rather than the PCI Express lane used by the similar AirPort card. We also know that the lauded performance of the device is due to its chips and controller rather than skipping SATA in favor of PCIe as some had speculated.

Implications of the 2011 MacBook Air’s Unconventional SSD

Is Apple already abandoning the "blade" SSD in the MacBook Air?

As techies moan about the lack of upgrade options presented by a soldered in SSD, they miss the bigger industry picture. For too long, computers have been held back by traditional SCSI and ATA controllers. These are both a performance bottleneck and an impediment to innovation. A shift to an integrated PCI storage model makes much sense tactically and strategically for Apple, and I expect that these rumors are true. Furthermore, this move will put even more stress on Windows PC makers. Once again, Apple is outmaneuvering the competition.
