Seagate 600 SSD 480 review
As one of the three surviving manufacturers of hard disks on planet Earth, you could be forgiven for thinking that Seagate would have a major interest in the technology that’s scheduled to replace the hard disk. Until recently at least though you’d be wrong, but Seagate did join the PC solid-state party relatively recently, just 12 months ago with its 600 SSD range.
For the current if endangered SATA-standard drives, Seagate offers a regular and Pro version, the latter baking in a little more endurance thanks to higher-grade NAND stock and the use of higher over-provisioning. We tested the normal 600 SSD in its largest 480 GB capacity.

Following Corsair’s lead and its Neutron GTX SSD, Seagate has plumped for a controller from a relative newcomer in such technology, Link A Media Devices, also known as LAMD. In fact the Seagate 600 SSD uses the same LM87800 chip as Corsair, but different firmware means results could be quite different.
With 555 MB/s reading from the ATTO benchmark, the Seagate 600 SSD is not troubled by large sequential reads. Its sequential write is a little lower than some of the competition though at 458 MB/s, where most get closer to 500 MB/s. That’s the lowest of this group but not a major cause of concern.
As we found with Corsair’s implemetation, but not necessarily a given with different firmware, the LAMD controller does not employ data compression techniques to inflate performance figures. Looking at the CrystalDiskMark results for 0x00 and random data we get broadly the same results in sequential testing, 495 and 502 MB/s for reads, and 458 and 462 MB/s writes.
Looking at small-file transfer characteristics, the Seagate 600 SSD behaved reasonably well with single-threaded 4 kB data, hitting 28 MB/s for reads and 78 MB/s for writes. As queue depth is increased the Seagate scales well, nudging 97 k IOPS for reads with 32 threads and 8 k IOPS for writes. Raise the queue depth higher though and performance tails off more than other drives, as measured by AS SSD, with around 82 k and 78 k IOPS respectively for reads and writes. This is not a typical usage scenario though, as few real-world tasks would juggle so many separate threads.
The Seagate 600 SSD is a good value but high-performance solid-state drive. Now over one year old, it’s available at very competitive prices, around 42p per gigabyte for the larger 480 GB capacity model.
