ADATA Announces CFast 2.0 "Industrial Memory Cards"
Subject: General Tech, Storage, Mobile | June 16, 2014 - 05:54 AM | Scott Michaud
CFast is a standard, based on the merging of CompactFlash with SATA, for memory cards to have SSD-like performance. It has been around for a while, CFast 2.0 having been released in Q4 2012, but with very limited adoption. You could count the number of camera models which use it on a single hand. Still, ADATA is entering that market with a lineup of memory cards, with quite a bit of variety.
The ADATA ISC3E will come in SLC (one stored bit per memory cell) and MLC (two stored bits per memory cell) models. Capacities will range from 4GB to 64GB (SLC) or 4GB to 128GB (MLC). Speeds are fairly low, compared to modern SSDs. SLC is rated at 165 MB/s read and 170 MB/s write, while MLC can read at 435 MB/s and write at 120 MB/s. They support ECC and S.M.A.R.T.
Of course, this is kind-of interesting in terms of its small, removable form factor. Beyond that, it seems to be a few years back in terms of SSD technology. For the high resolution (or high frame rate) camera use case, read and write speeds really do not matter, except when you transfer your media off of your device (which the MLC version is clearly better suited for). Otherwise, as long as your write speed is consistently above what the camera can output, going bigger will be wasted overhead. ADATA suggests using these CFast 2.0 cards in POS terminals and kiosks but, at that point, would you really need small and removable memory?
ADATA has not released pricing and availability.
