Fastest Half-Slim SATA III Solid-State Drive Launched by Transcend
The drive uses the latest SATA specification but is not as fast as some may hope
I've become rather used to reading and hearing about solid-state drives with transfer speeds of 550/540 MB/s when reading and just a little less when writing, but Transcend's latest item is not that sort.Instead, the HSD740 is a half-slim SATA III 6Gb that, true, happens to be the fastest in the world (or so Transcend claims), but that doesn't mean what some would think it means.
The newcomer reads files at 510 MB/s indeed, but the writing speed is limited to 185 MB/s.
Still, the SSD is quite small (54 x 39 x 4 mm / 2.12 x 1.53 x 0.15 inches) so that's still something, and comes with the benefits of greater design flexibility and cost savings. Ultrabook makers should love it.
Then again, if it does end up in laptops, it will only function as cache drive, since the capacity is rather modest (and is responsible for the low write speed): 32GB / 64GB.
