Earlier available only through the OEM channel, Samsung 840 EVO mSATA 1 TB, the highest capacity mSATA SSD, is beginning to show up in retail channels, stateside. B&H Photo Video has the drive listed on pre-order for US $615. The drive is sought after in the production industry, particularly by users of digital video cameras that feature mSATA SSD slots, as it allows you to film lossless high-resolution video longer. It's also a potential favorite among Ultrabook users. The 840 EVO mSATA features Samsung's MEX controller, which embeds a triple-core ARM processor; and TLC NAND flash memory. It offers impressive sequential speeds of up to 540 MB/s reads, and up to 520 MB/s writes. The controller uses no over-provisioning, and relies on a 1 GB LPDDR3 DRAM as scratchpad. The other sizes the 840 EVO mSATA is available in, include 120 GB, 250 GB, and 500 GB.
