Tagged: hybrid hdd, cache, Seagate, 2TB

Benchmarking cached HDDs can be a difficult task as they are specifically designed to cache commonly used data which results in two very different speeds for data access, the 8GB SSD and the actual HDD.  The Tech Report recently met this challenge when benchmarking Seagate's first 3.5" desktop cached drive with 8GB of flash and 2TB of platter storage.  When contrasting it to some of the higher end HDDs available it became apparent that the more expensive WD Black 4TB was a faster drive but as it does cost more per gigabyte it might not be the best choice for every purpose.  Check out the review to see if this hybrid device is a better choice than buying both a small sized SSD and a large HDD for your own usage.

Enthusiasts are wholeheartedly adopting SSDs for their storage media of choice with HDDs relegated to long term storage of infrequently accessed storage.  For SMB and enterprise it is not such an easy choice as the expense to move to a purely SSD infrastructure is daunting and often not the most cost effective way to run their business.  That is why HDD makers continue to develop new technology for platter based storage such as HAMR and shingled magnetic media in an attempt to speed up platter drives as well as increasing the storage density.  Today at The Register you can read about a variety of technologies that will keep the platter alive, from Seagate's cached Enterprise Turbo SSHD, HGST's helium filled drives and the latest predictions on when HAMR and SMR drives could arrive on the market.

Seagate Introduces Enterprise Turbo SSHD 2.5" SAS Drive For Servers

Subject: Storage | July 26, 2013 - 12:35 AM |
Tagged: turbo sshd, sshd, Seagate, nand, enterprise

Earlier this week Seagate took the wraps off of its latest Solid State Hybrid Drive (SSHD). Dubbed the Enterprise Turbo SSHD, this latest model is aimed at the enterprise server market. The drives combine a traditional 10K SAS mechanical hard drive in capacities up to 600GB with up to 32GB of NAND flash.

The 2.5" Enterprise Turbo SSHDs are aimed at servers with big data analytics, virtual desktops, and transaction processing workloads. The NAND flash acts as a cache for the mechanical hard drive, and caching is done by the controller at an I/O level.

According to Seagate, the company has been working with IBM over the past year to put the new SSHD through its paces. As such, the hybrid drives will first be available in the IBM X and BladeCentral servers. The IBM versions will have 16GB of NAND flash and one year warranties according to the documentation available online.

Seagate further claims up to three times random performance increase versus 15K SAS mechanical hard drives. The 600GB 10K SSHD is rated to have up to two times better IOPS than a traditional 10K SAS hard drive without a NAND cache.

Introduction

Introduction

Seagate recently announced and released their third generation of laptop Solid State Hybrid Drives. Originally thier hybrids carried the Momentus (laptop HDD) name forward, tacking on 'XT' to denote the on-board caching ability. The Momentus XT was intriduced in a 500GB (1st gen) and 750GB (2nd gen) model. The new line gets a new and simple title - Laptop SSHD.

laptop-sshd-family-gallery-500x500.jpg

In addition to the new name, we now have two capacity points available. The 'Laptop SSHD' retains the old 9.5mm form factor and now pushes a full 1TB of capacity, while the 'Laptop Thin SSHD' drops a platter and reduces availabile capacity to 500GB. The bonus with the 500GB model is that it maintains similar performance yet shaves off some thickness, making it Seagate's first 7mm Hybrid.

Today we will take a look at the new Thin SSHD, comparing it to the performance of the older generation Seagate Hybrids, as well as to Intel's RST caching solution:

Seagate Unveils 12Gbps SAS 1200 Series and PCI-E X8 Accelerator SSDs for the Enterprise Market

Subject: Storage | May 7, 2013 - 06:31 PM |
Tagged: x8 accelerator, virident, ssd, seagate 1200, Seagate, pci-e

In addition to its recently-announced 600 and 600 Pro consumer line of solid state drives, Seagate has unveiled two new drives aimed at the enterprise SSD market. The Seagate 1200 series is a 2.5" SAS SSD and the Seagate X8 is a PCI-E based accelerator card.

Unfortunately, details are extremely scarce on both upcoming enterprise drives. Performance, specifications, pricing, and availability are still unknown. Seagate has officially confirmed there existence and shared a few tidbits of information, however.

Seagate PCI-E X8 Accelerator SSD.jpg

The Seagate 1200 SSDs are 2.5" form factor drives with a 12Gbps SAS interface, which suggests that they will be at least somewhat faster than the consumer versions due to Seagate implementing the faster drive interface. The most important detail however, is that Seagate will be using its own custom SSD controller in the 1200 series. The new controller is still a mystery, but it is developed by Seagate and not Link A Media with customized firmware like the 600 and 600 Pro drives. I am especially interested to find out more about this aspect of the drive. Hopefully the new controller is successful and will trickle down to the company's next-generation consumer SSDs.

Meanwhile, Seagate's X8 Accelerator card is a half-height, half-length expansion card with up to 2.2TB of flash memory. The new PCI-E based drive is based on technology from Virident and can be used to accelerate applicators or database operations in servers. It will be available in capacities ranging from 550GB to 2.2TB. The SSD controller/management duties are handled by the host system's CPU and maintenance operations like garbage collection can be scheduled for periods of downtime when the server is not being hit hard by things like database requests for a popular web application. According to Seagate, each X8 Accelerator will be capable of up to 1.5 million IOPS.

Both of the new enterprise solid state drives will be released later this year.

Seagate's SSD is new but the components are familiar

Subject: General Tech | May 7, 2013 - 03:44 PM |
Tagged: ssd, Seagate, LM87800, 600 Pro, 600, LAMD

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

Subject: Storage | May 7, 2013 - 02:27 PM |
Tagged: ssd, Seagate, LM87800, 600 Pro, 600

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.

Seagate Logo.jpg

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.
