Samsung Set to Ship Terabyte Flash Drive

The 1TB 840 EVO SSD requires about $600 and PC with an mSATA slot.

Samsung is ready to ship its biggest flash drive ever: A mini-Serial ATA Solid State Drive (SSD) with 1 terabyte of capacity.

The Samsung 840 EVO mSATA SSD, which Samsung unveiled in July, is one fourth the size of a 2.5-inch SSD, with the same level of performance, according to the company.

Much of that performance comes from Samsun’s Magician 4.3 system software, which includes a Real-time Accelerated Processing of I/O Data (RAPID) mode that drives the sequential-read speed to more than 1,000MB/sec. The chips are built using a leading-edge 19-nanmometer process with a self-adjusting cache and good performance boost from RAPID, which Samsung got in its acquisition of SSD-caching specialist NVELO a year ago, according to a detailed review in in August.

The giant SSD is able to run in a notebook or laptop with other SSD or HDD storage, as long as the machine has an mSATA socket and should cost about $600. The 840 mSATA SSD reaches 1TB using four of Samsung’s 128 Gbit NAND memory packages, each with 16 layers of 128Gbit chips. Specs describe it as able to manage 98,000 read and 90,000 random write IOPS and a sequential read/write speed of 540MB/sec-520MB/sec.

Other versions come in 120GB, 250GB and 500GB. They include 256-bit AES encryption keys and comply with both the Trusted Computing Group’s Opal specification for applying policy-based security and encryption to storage hardware, and the IEEE 1667 standard for mobile-storage hardware to authenticate to other systems.

Samsung’s 840 EVO SSDs are a top choice for consumer notebooks due to the good balance of price and performance and Samsung’s solid “reputation for reliability that a lot of other vendors lack,” according to an August review of desktop SSD products in the blog TheWirecutter.

The 840 EVO series will be available this month, though prices and precise ship times depend on region, according to Samsung.
