The recently-released MacBook Pro firmware that promises to enable 3.0Gbps SATA connectivity has ironically been causing problems in third-party drives. Apple released the upgrade earlier this week, after users of the new 13- and 15-inch MacBook Pro models reported that the notebooks were limited to 1.5Gbps SATA; this did not affect the speed of standard-fit hard-drives, but may have limited future performance should the user upgrade to a faster HDD or SSD. Now, some users with third-party drives already installed are reporting frequent pauses, usage spikes and data errors with the new firmware.

Both traditional hard-drives and solid-state storage are presenting problems. One user found his Western Digital Scorpio Blue HDD now suffers intermittent data errors and that the whole machine freezes randomly. Meanwhile another user who has upgraded to an Intel X25-M SSD found his drive no longer works at all following the firmware update. Some have found that re-installing the original SATA 1.5Gbps drive supplied by Apple restores the machine to working order, while others have had no luck.

Apple distanced themselves from aftermarket upgrades when they first released the firmware, warning users that they had “not qualified or offered these drives for Mac notebooks” and that “their use is unsupported.” That seems to mean they won’t fix the issue under warranty: many who have contacted Apple Stores or technical support regarding the firmware issues have been told that “Apple is not responsible for maintaining compatibility with third-party aftermarket hardware with their firmware updates.” However there is also talk that Apple Store “Geniuses” can roll back the firmware if there was a problem during the upgrade itself, though not otherwise.

Samsung have announced a solid-state drive (SSD) that fits onto a mini-PCIe card, offering up to 64GB capacity in a form-factor nearly 80-percent smaller than a 2.5-inch drive. The SATA 3.0 Gbps drive is not only intended for compact devices, such as MIDs and netbooks, but as a secondary or complementary drive for regular notebooks.

In that way, users would no longer have to choose between the speed of SSD and the low price of traditional hard-drives, but instead have both. The mini-PCIe card weighs up to 8.5g and boasts 200MB/s read rates and 100MB/s write rates.

It also supports full-drive encryption and the usual shock-resistance of an SSD. Samsung are currently sampling the SATA mini-card SSD to its hardware partners, while pushing for standardization on its mechanical form-factor and pin-layout. That’s expected to be completed by Q3 2009; there’s no word on when we could see the drives reach the market.

MacBook Pro confusion this weekend, as some owners of the new unibody 13- and 15-inch notebooks are reporting that their machines are apparently limited to 1.5Gb/s SATA connections rather than the faster 3.0Gb/s SATA-II. Full details are unclear, but it seems that Apple have either switched to SATA hardware or used firmware for the newest MacBook Pros that limits hard-drive connections to the slower speed.

The move has the most impact on those who upgraded to the SSD option in their new MacBook Pro. Regular hard-drives, which the notebooks are both fitted with as standard, will prove unaffected, as the read/write speeds of the drive are slower than SATA. However SSDs, which can manage higher sustained read rates, are clocking in with lower speeds compared to previous-generation MacBooks and MacBook Pros.

Any impact on real-world performance, however, is unknown. Transferring files to external drives would be limited by the USB/Firewire connection rather than the choice of SATA or SATA-II. It’s possible that a new firmware update could “unlock” the faster connectivity, but so far Apple have not publicly commented.

OCZ Technology seems to always be toiling away on new solid state drives, but it's rare to find any from the company that are priced for the average Joe / Jane. Rather than aiming specifically for the fat-walleted enthusiast crowd, the Agility series is hoping to make a decent sized splash in the mainstream market. These 2.5-inch SATA II SSDs promise 230MB/sec read and 135MB/sec write speeds, along with 64MB of cache and a two-year warranty. We pinged OCZ for details surrounding pricing and availability, so here's the dirt: the trio of models will be available in a fortnight or so for $129.99 (30GB), $219.99 (60GB) and $349.99 (120GB).
