SanDisk has upgraded its SSD lineup by doubling capacity and “significantly” boosting performance. According to the fantastically named company spokesperson Doron Myersdorf, the new G4 SSD is designed as a “drop-in” replacement for notebook hard disk drives, while the new P4 will allow manufacturers to create “even thinner” devices.

The Register notes that the previous G3 model offered 60 and 120GB with a 2220MB/sec read speed and 120MB/sec write speed, and an endurance of 80TB written. Whereas the new G4 offers sequential read/write speeds of up to 220 and 160MB/sec and a 160TB written endurance rating, enough for a decade of normal use according to SanDisk.

Added Myersdorf , “SanDisk SSD P4 and SanDisk SSD G4 offer up to 128 gigabytes (GB) and 256GB of storage respectively. [Both] SSDs use SanDisk’s advanced 32-nanometer (nm) multi-level cell (MLC) process technology, which enables cost-competitive high-capacity storage with a tiny footprint. The drives offer faster boot times and improved system responsiveness by utilising our Adaptive Flash Management technology.”

TG Daily reports that Myersdorf also noted that the SSD P4 was “ideal” for use in small devices such as tablets, netbooks, smartbooks, ultra-thin notebooks and set top boxes (STBs).

“[Our] AFM implementation for SanDisk SSD P4 [utilizes] nCache acceleration, a large non-volatile write cache technology. [This] boosts burst random write performance (up to 600 IOPS) to shorten boot times, helps prevent ‘stalling’ [or] ‘hiccups’ and increases system responsiveness.”
