Seagate 600

The Seagate 600 is the company’s first entry into the SSD market. There are two models, a 5mm and a 7mm, both with available seagate_600_ssdcapacities of 120 GB, 240 GB and 480 GB. All drives use the SATA III 6 GB/s interface and utilizes MLC NAND flash modules. Seagate avoids giving exact numbers for the sequential speeds; they only reveal that the drives can exceed 500 MB/s and 400 MB/s for read and write respectively.

Running the show for the Seagate 600 is Link A Media LM 87800 6Gbps controller with Toshiba 19nm 64GB Toggle mode MLC NAND flash modules.  The components are similar to what is found inside the Corsair Neutron SSD. Seagate reports that the Annualized Failure Rate (AFR) for all models of the 600 is 0.58%. Similarly, the 480 and 240 GB models can endure 72 TB of written data while the 120 GB model can endure 36.5 TB of written data.

Seagate’s 600 SSD is a great drive, particularly thanks to how well it performs in a full drive scenario.


Bottom line: aside from its power consumption, which is among the worst we’ve seen from a modern SSD, and a goofy limited warranty, there isn’t much we can hold against Seagate’s standard 600 SSD


As far as the benchmarks go, they consistently exceed specifications listed by Seagate and we see read performance of over 500MB/s and write performance just below.
