write speed.īy comparison, Intel's fastest consumer SSD, the 520 Series, recorded a maximum read rate of 456MB/sec. The first time I fired up my Blackmagic Disk Speed Test benchmarking software and tested the Seagate 600 SSD, I was pleasantly surprised the drive attained a maximum read performance of 512MB/sec. There are eight NAND channels to the flash chips, which offers a good deal of parallel flash access to I/O channels. The Seagate 600 uses 19 nanometer (nm) process multi-level cell (MLC) NAND flash chips. The Seagate 600 has a retail price tag of about $110 for a 120GB model, $209 for a 240GB drive and $410 for a 480GB model, the one I tested. Seagate 600 SSDįor the Seagate 600, its first consumer SSD, the company chose to use the LM87800 controller from Link A Media Device (LAMD), a company that was recently acquired by memory chip giant Hynix. Seagate has dabbled in the consumer space with hybrid drives that combine a small amount of NAND flash cache with traditional spinning disks in 2.5-in. While higher capacity SSDs can have better performance than lower, after fully populating them and using them for a day, I do not believe the benchmark test results were markedly impacted by capacity differences. I used the 512GB model of the Samsung 840 Pro Series, the 256GB model of the OCZ Vertex 450 family and the 480GB model of the Seagate 600 SSD lineup.
Note that the three test SSDs did not have the same capacities. In addition, the drives were each used for a day to ensure they were not "fresh" out of the box, which can result in higher performance than a used drive. To create a typical work environment on each drive, I used StarTech's Portable eSATA to USB Duplicator Dock to create copies of a fully populated SSD that contained my OS and all my work applications and content, amounting to 180GB of data. Lastly, I tested all the drives with multiple boot ups, shutdowns and restarts. I also tested each SSD by uploading a 2GB MP4 video. I tested the SSDs using Blackmagic Disk Speed Test benchmarking software for Macs.
(Many existing laptops still have a 3Gbps SATA 2.0 interface.)
The computer has a SATA 3.0, 6Gbps internal drive interface all of the SSDs I tested also use the SATA 3.0 interface. For the benchmark tests, I used an Apple MacBook Pro running OS X Mountain Lion (v10.8.4) with 8GB of RAM and a 2.5GHz Intel Core i5 processor.
