Corsair Neutron XT (240GB, 480GB & 960GB) SSD Review: Phison S10 Debuts

The ugly truth is that the SSD market has been tough for almost all the typical PC component vendors lately. With Samsung, SanDisk, and Micron/Crucial being serious about the client market, it's not easy for other companies to find a way to provide any substantial advantage over the big brands. The fab owners will always enjoy a cost advantage, which is why we have seen a few companies backing off from the market and many more for whom SSDs have become just another series in the pool of products. 

This is what could be said to have happened at Corsair. While the company has never been super aggressive on the SSD side, the past year or so has been very quiet. There have been a couple of new releases, such as the Force LS and Force LX, but nothing close to the exclusive deal Corsair scored with Link A Media (LAMD) two years ago.

One way to perceive whether a company is serious about a specific model is with the media sampling process. If there is no embargo and only one capacity is available for review, then historically the product has not been a substantial or interesting release. If, on the other hand, there is an official release date and the manufacturer samples several of the available capacities, then this can be a sign that the product might be a bit more special. This is never a hard and fast rule, and it is always welcome to be surprised.

From the title, the Neutron XT from Corsair is a member of the latter case. This is the first time Corsair has offered us the full set of drives since the original Neutron and Neutron GTX, and the Neutron XT is the first drive to ship with Phison's new S10 controller.

Phison actually sent us reference design samples of the S10 prior to Corsair, but we were asked to review the Neutron XT first (as Corsair is a household name while Phison is pretty much the opposite). However, Phison asked us to save the technical analysis of the controller and its architecture for the separate reference design article, so I'll keep to the basic details for now; stay tuned for a more in-depth analysis of the S10 in the next two weeks.

The biggest change in the S10 compared to the S8 is the upgrade to a quad-core CPU architecture. Three of the cores are dedicated to internal flash management (garbage collection, wear-leveling etc.), whereas one will handle the host operations. The NAND channel count remains at eight like in the S8, which seems to have become the standard for client-grade controllers. Capacity support goes as high as 2TB and the S10 design can also support TLC NAND, although that is not fully ready yet.

Corsair Neutron XT Specifications

Availability December

EDIT: Corsair had an error in the reviewer's guide, so the warranty is actually five years similar to the original Neutron series.

Corsair is offering the Neutron XT in three capacities: 240GB, 480GB and 960GB. The Neutron brand has always been more of a high-end enthusiast/gamer brand, so it makes sense to skip the 120GB model because the majority of the target population will be aiming at 240GB at a minimum.

On the NAND front Corsair is using Toshiba's A19nm MLC NAND. The 240GB and 480GB models are equipped with 64Gbit dies to provide higher parallelism and performance, whereas the 960GB model has enough NAND on its own to provide the necessary parallelism and performance with a 128Gbit die.

Like many platforms on the market, the S10 features a page-level parity scheme that Phison calls 'Page RAID ECC Parity' to protect against NAND failures. Unfortunately Phison couldn't disclose the parity ratio (i.e. how much NAND is dedicated to parity), which makes calculating the exact over-provisioning impossible, but I was told that the feature only provides page-level protection and can't tolerate a full block or die failure. 

Corsair is not announcing pricing yet because the drive is not officially launching until early December, which would subject the prices to fluctuation. However, I'll make sure to update this article with the pricing information once that becomes available.

Corsair Neutron XT 240 GiB SSD Review - Hardware Secrets

While the 120 GiB SSDs are the most popular models because of their low cost, 240 GiB models are becoming affordable, and thus becoming the preferred ones. Today, we will test the Corsair Neutron XT 240 GiB, targeted to the high-performance market.

The Corsair Neutron XT SSD uses the 2.5” form factor with a height of 7 mm, makes use of the SATA-600 interface, and can be found in 240 GiB, 480 GiB, and 960 GiB capacities. The 240 GiB model, which is the one we are benchmarking, has 256 GiB of memory inside, but is sold as 240 GiB, since 16 GiB are reserved for overprovisioning, used by the garbage collection and wear leveling mechanisms of the unit.

In our tests, we will compare the performance of the Neutron XT 240 GiB against the Kingston HyperX Fury with the same capacity.

Before proceeding, we highly suggest that you read our “Anatomy of SSD Units” tutorial, which provides all the background information you need to know about SSDs.

In the table below we compare the Corsair Neutron XT 240 GiB with the Kingston HyperX Fury 240 GiB. Both units use a SATA-600 interface, 2.5” form factor (7 mm height), and MLC memory chips.

Manufacturer Model Model # Nominal Capacity Price
Corsair Neutron XT CCSD-N240GBXT 240 GiB USD 140
Kingston HyperX Fury SHFS37A/240G 240 GiB USD 110

Corsair Neutron XT SSD Preview

Until now, Link_A_Media Devices was the exclusive controller maker for Corsair's Neutron branded products. LAMD was acquired by SK Hynix, and since, the company has been slow to release new products to market. We suspect LAMD's slow roll out is due to Mike Lee, the Director of SSD SOC Development leaving to start Tidal Systems in May 2013. At Flash Memory Summit, we met with SK Hynix and saw several interesting products on display, but learned consumer focused controllers weren't planned for 2014.

Corsair isn't LAMD's only customer for SSD controllers, Seagate's 600 and 600 Pro also use controllers from the company. Seagate recently purchased SandForce from Avago to further both consumer and enterprise SSD products. This leads us to question if we'll ever see a viable consumer SSD from LAMD again.

With Corsair's flagship product line stagnant, the company needed to find a new source to power a flagship SSD product. We previewed Phison's new quad-core S10 controller back in July with very early firmware. The early results were mixed, but the S10 showed a lot of potential for a product that was so early in the firmware development cycle.

The Phison S10 controller uses a quad-core processor that dedicates three cores to flash management. Often overlooked and rarely understood, background tasks make up a majority of the controllers processing power. The faster and more efficient the background activity, the faster your front-end performance. The front-end side is what users see when opening files, transferring data and so forth. If your SOC is busy shuffling data around to manage wear, the front-end performance suffers. Some SSDs try to push back end tasks when the SSD is in an idle state or until absolutely needed, while others try to perform background tasks as soon as possible - we often call this activity aggressive garbage collection. There are pros and cons for each but with so many resources dedicated to background activity; the Phison S10 is able to reduce the amount of time needed to perform background operations.

We'll talk in depth about the new Phison S10 quad-core controller next week in a deep dive article that covers in detail all of the new advanced technology included. At this time, the firmware is final for mass production, but a few bells and whistles are yet to be enabled.

Specifications, Pricing and Availability

Corsair plans to release the Neutron XT in three capacity sizes: 240GB, 480GB and 960GB. Today we're focusing mainly on the largest capacity size model, but will add the two smaller capacity size drives in the some performance charts. We'll follow up this preview of the 960GB model with individual reviews of the 480GB and 240GB later this week so we can all see how the drives compare to other products in the same capacity class.

The stated performance from Corsair is 560 MB/s sequential read, 540 MB/s sequential write speeds. Random performance tips the scale at 100K random read IOPS and 90K random write IOPS. We see the 100K read IOPS mark touted often, but in our ASUS ROG Z87 test system, we have yet to break that barrier with a consumer SATA SSD... until today.

Three main points were made about the Neutron XT in our marketing material from Corsair. The first is extreme performance; the Phison PS3110-S10 was designed to compete with the fastest SSDs on the market today. The controller was actually designed for both MLC and TLC NAND flash, the latter needing more controller resources for flash management. Paired with MLC NAND flash, the Phison S10 turns into a performance beast that is capable of consistent performance under heavy workloads.

The TLC side also increases reliability for MLC flash. So many features go into keeping TLC flash reliable. Current TLC flash has around 1K P/E cycles compared to 3K P/E cycles for 1xnm and 2xnm MLC. Phison's proprietary technology designed for TLC flash endurance increases the reliability of MLC flash.

The final checkbox incorporates Corsair's SSD Toolbox software to manipulate the Neutron XT Series along with Corsair's other SSDs. You can read about the Corsair SSD Toolbox in this article that discusses all of the software features.

At this time, we don't have pricing information, but we know the Neutron XT will be available in December. The drive will ship with a five-year warranty, and a 7mm to 9.5mm spacer. As mentioned in the introduction, the firmware is nearly final, but the Neutron XT is missing support for DEVSLP / Slumber at this time. These features should be complete in the coming weeks and ship enabled in the final retail units. I think most will be surprised with the results of our Notebook Battery Life Test even without the low power states working.

Our early samples arrived in black cases, but the final retail product coming in December will have a red case like the Force GS, also from Corsair. We have all three capacity sizes available to test, but will focus on the 960GB model in this section.

The Neutron XT uses a 7mm z-height so it will fit in notebooks and Ultrabooks that require a 7mm drive like some Lenovo T430 models.

Our sample model didn't use a thermal pad to transfer heat from the controller, DRAM or flash to the case. We'll look at the heat output later in this review with our FLIR camera.

Corsair managed to stuff all 1TB of capacity in just eight NAND flash packages. This model uses two DRAM packages for buffering data, the 480BG and 240GB models use a single DRAM package for this.

Here we get our first look at the final silicon Phison S10 controller.

Corsair used A19, AKA second-generation 19nm Toshiba toggle flash for the Neutron XT.

There are two Nanya DDR3 DRAM packages with 16x 256Mb die for a total of 512MB per package or 1GB of DDR3 total in the 960GB Neutron XT.

Corsair Neutron XT 240GB SSD Review

Posted by Nathan Kirsch Tue, Nov 18, 2014 - 9:01 AM

Corsair Neutron XT 240GB SSD – The First Phison 3110 Controller Drive

The Corsair Neutron XT series SSDs is the latest storage drive to be released by Corsair. The Corsair Neutron XT 240GB drive is powered by a Phison 3110-S10 controller (aka Phison S10), which was just introduced in August 2014. This is the first time that we have seen the Phison 3110 controller on a consumer SSD, so we can’t wait to see how Phison’s  brand new high-performance controller performs. Corsair sent over the Neutron XT 240GB drive to try out ahead of its official release and didn’t tell us much. The drive we got did not come in retail packaging, we weren’t told where it fits in the Corsair SSD lineup, pricing has yet to be set and when we asked for power efficiency numbers and writes per day we were told that information wasn’t yet available. What we do know is that it uses the Phison PS3110-S10 controller and utilizes Toshiba A19 MLC NAND Flash. The drive is rated at having up to 560MB/s read and 540MB/s write speeds for sequential operations and up to 100K IOPS random read QD32 and 90K IOPS random write QD32. Corsair says that the Neutron XT series will bridge the gap between high performance enthusiasts and multimedia professionals.

Corsair Neutron XT Series Drives:

  • Corsair Neutron XT 240GB – CSSD-N240GBXT
  • Corsair Neutron XT 480GB – CSSD-N480GBXT
  • Corsair Neutron XT 960GB – CSSD-N960GBXT

Corsair Neutron XT Specifications:

  • SSD Controller: Phison PS3110-S10
  • NAND: Toshiba A19 MLC
  • Unformatted Capacity: 240GB / 480GB / 960GB
  • Max Sequential Read (ATTO): Up to 560MB/s
  • Max Sequential Write (ATTO): Up to 540MB/s
  • Max Random Read QD32 (Iometer): Up to 100K IOPS
  • Max Random Write QD32 (Iometer): Up to 90K IOPS
  • Form Factor: 2.5-inch with a 7mm z-height
  • Interface Type: SATA 6.0 Gb/s (SATA 3)
  • Warranty: 3 years

Corsair placed a 3-year warranty on the Neutron XT, which is actually underwhelming for high-end SSDs as many companies have increased their warranty lengths to 5-years and even 10-years. Warranties most certainly do play a role when it comes to purchasing a drive, so we hope that Corsair becomes a little more aggressive on the warranty front to stay competitive with companies like Samsung, Sandisk and OCZ.

The Corsair Neutron XT drive that we will be looking at today is the 240GB model that is sold under part number CSSD-N240GBXT. This is a 7mm drive that comes with a small spacer with adhesive tape for it to fit in 9.5mm notebooks properly. The drive has mounting holes on both the side and bottom, so it should be usable for most any notebook or notebook that uses a standard SATA connector.  The Neutron XT has a metal housing with a painted red finish on it. There are stickers on the front and the back of the drive for informational and marketing purposes.

On the back of the red metal 2.5-inch enclosure you can see that the Neutron XT series has the standard drive mounting holes on the bottom and that Corsair is using standard Serial ATA power and data connectors, so you can use this SATA III (6Gbps) drive in pretty much anything and it is backwards compatible with older SATA II systems. The sticker on the back of the drive says that the warranty is void if the sticker is removed, which is odd as there is nothing below the sticker. In fact, there are no screws on this drive whatsoever. Corsair game up with a simple enclosure design that requires no screws and there are pairs of metal retainers in each corner that can be popped apart in order to disassemble the drive.

Let’s crack open the drive and look inside!
