Seagate has used Link_A_Media's Amber LM87800 controller and Toshiba Type C 19nm MLC NAND along with their own custom firmware to create the Seagate 600 series of SSDs.  The components are very similar to Corsair's Neutron series of drives, it seems that the biggest difference is going to be in the functionality of the firmware.  The first difference [H]ard|OCP spotted was in the efficiency of the drives, they pulled less power than their rivals and the Pro version sported enhanced endurance and power capacitors which will be very important to enterprise users.  Check out the full review to see where they sit in the pack after the benchmarks were all completed.

"Seagate refreshes its line of consumer and enterprise SSDs with a new family of third-generation SSD products. We take a look at the consumer mainstream Seagate 600 and the enthusiast model, the Seagate 600 Pro. Will its LAMD Amber LM87800 controller, custom firmware, and Toshiba Type C 19nm MLC NAND make it a standout?"

Seagate Enters The SSD Market With The 600 and 600 Pro SSD Series

Seagate has officially moved into the solid state drive (SSD) market with two new consumer drives: the 600 and 600 Pro series. The new drives come in capacities ranging from 100GB to 480GB. Both series utilize the Link A Media (LAMD) LM87800 SSD controller and 19nm 2-bit per cell MLC NAND flash from Toshiba. Seagate has not provided pricing or availability dates, but pricing should be in-line with existing drives, and reviews are already available around the Internet.

The Seagate 600 series is the lowest-tier solid state drive. It will be available in 120, 240, and 480GB capacities. Seagate is using 128GB, 256, and 512GB of NAND flash on 2, 4, and 8 channels respectively. In addition to the LM87800 SSD controller (which features custom Seagate firmware) and NAND flash, Seagate is including 1MB of DDR2-800 DRAM per 1GB of NAND flash for a total of 128, 256, and 512MB of DRAM on the 120, 240, and 480GB capacity drives.

The 600 Series is rated at up to 500MB/s peak 128KB reads and 400MB/s writes (limited to 300MB/s on the lowest-capacity 120GB drive). Further, Seagate states that the 120GB drive is capable of 80,000 random read and 60,000 random write (4K) IOPS, while the 240GB and 480GB drives can reach up to 80,000 random read and 70,000 random write (4K) IOPS.
Also note that the 600 series comes in both 7mm and 5mm form factors, which makes it compatible with most laptops. Seagate provides a 3 year warranty on the 600 series.

The Seagate 600 Pro series steps things up a notch by adding overprovisioning, capacitors for power-loss protection, and a longer 5 year warranty. The 600 Pro series will come in 100, 120, 200, 240, 400, and 480GB capacities. The 100, 200, and 400GB versions of the SSD offer additional overprovisioning which gives the SSD controller more space to work with. The capacitores are intended to provide enough power in the event of a PC power loss to write all data to the NAND flash and prevent data loss.

The 600 Pro drives offer the same 6Gbps SATA interface, LM87800 controller, and 1MB-to-1GB DRAM to NAND ratio. The Pro drives do not come in the 5mm high form factor, so laptop compatibility is limited.

Further, the 600 Pro Seagate SSDs are faster drives. According to Seagate, the Pro series offers up to 85,000 and 30,000 random read and write (4K) IOPS on the overprovisioned drives and p to 85,000/11,000 random IOPS on the 240 and 480GB drives. The 100 and 120GB drives are slower than the other drives though due to less NAND flash and channels between the flash and controller. The chart below details the rated specifications for all of the announced drives.

Series 600 Pro 600 Pro 600 Pro 600 Pro 600 Pro 600 Pro 600 600 600
Capacity 100GB 120GB 200GB 240GB 400GB 480GB 120GB 240GB 480GB
Random 4K r/w KIOPS 80/20 80/8 85/30 85/11 85/30 85/11 80/60 80/70 80/70
128KB r/w sustained sequential             >500/>300 >500/>400 >500/>400
128KB peak sequential r/w 520/300 520/300 520/450 520/450 520/450 520/450      

Blank areas indicate that rated specifications were not available.

Fortunately, the reviews available online (such as AnandTech's) do seem to support the new drives as far as performance is concerned. The drives are stacking up nicely versus the competition, which is interesting given the controller choice. For example, the sequential read speed looks promising.

The 600 and 600 Pro drives are looking like solid drives so long as the pricing is competitive. I'm excited to see where Seagate goes from here.

Corsair's new Neutron family of SSDs with the brand new LAMD controller

We have certainly seen a lot of new versions of SSD controllers from companies well established in the market but there haven't been any new companies join the market until earlier this month.  Corsair unveiled their new Neutron series of SSDs, featuring the new  LM87800 controller from Link A Media.  Both models contain a pair of Samsung DDR2-800 128MB DRAM cache for a total of 256MB of cache, the difference is in the flash, with the GXT sporting eight 32GB modules of Toshiba Toggle Mode 24nm NAND while the non-GTX model has sixteen 16GB modules of synchronous Micron 25nm NAND.  Check out SSD Reviews article to see how that effects the performance.

"It is always an exciting time when a new controller makes it’s way on to the SSD scene. It is like seeing a new contender in any sporting event and predicting their success based on the balance of strength and inexperience. Our analysis today examines the new Link A Media (LAMD) 6Gbps controller found within the Corsair Neutron and Neutron GTX SSDs. Watch as the Neutron delivers a first round knockout."
