Source : Engadget Greenhouse has announced new SSD disks for portables that they describe as the fastest in the industry.
Proposed with the format 2,5" and 9,5 mm height with the standard SATA interface (they can thus be fitted in the MacBook and MacBook Pro), they will be sold in capacities going from 16 to 64 GB with (faster) SLC memory and from 16 to 128 GB with MLC memory.
The data flow with SLC will be of 130 MB/s for reading and 67 MB/s for writing. The read speed with MLC remains excellent, however the write speed is quite slow, at 20 MB/s.
But of course, their claims regarding speed relates here only to the read speed…
The future could belong to the hybrid discs which certain manufacturers intend to produce. They would integrate a small portion of SLC memory, with the majority using MLC. These would keep the advantage of capacity of MLC while keeping the write speed of the SLC which would serve then as large cache for writing.
