For owners of Z97 or X99 boards with updated UEFIs or a rare SFF-8643 connector for the 2.5" version, booting from NVMe is possible, for the rest the Intel SSD 750 will have to be a storage drive.   Al recently looked at this more than impressive PCIe SSD and now [H]ard|OCP has had a bash at it.  The review is certainly worth checking out as some of their tests, especially the real world ones, differ from the benchmarks that Al used.  This will give you more information about how the new SSD will handle your workloads, research worth it if you are thinking of spending $1055 for the 1.2TB model.

"Intel is set to be the catalyst for a long-awaited leap forward in storage technology with the new SSD 750 bringing NVMe storage to client PCs for the first time, and turning the high end SSD space upside-down. We are expecting blinding IOPs and we dig in to find out what it can mean to the hardware enthusiast."

Introduction, Specifications and Packaging

Introduction:

Back in November of last year, we tested the Corsair Neutron XT, which was the first product to feature the Phison PS3110-S10 controller. First spotted at Flash Memory Summit, the S10 sports the following features:

  • Quad-core controller - Quad-core CPU dedicates three cores just to managing flash and maintaining performance
  • Maximum throughput and I/O - Offers speeds of up to 560 MB/s read and 540 MB/s write and 100K IOPs on read and 90 IOPs on write, saturating the SATA 6Gbps bus
  • End-to-end Data Path Protection - Enterprise level CRC/ECC corrects internal soft errors as well as detecting and correcting any errors that may arise between the DRAM, controller, and flash
  • SmartECC™ - Reconstructs defective/faulty pages when regular ECC fails
  • SmartRefresh™ - Monitors block ECC health status and refreshes blocks periodically to improve data retention
  • SmartFlush™ - Minimizes time data spends in cache to ensure data retention in the event of power loss
  • Advanced wear-leveling and garbage collection

Corsair was Phison's launch partner, but as that was a while ago, we now have two additional SSD models launching with the S10 at their core:

To the left is the Kingston HyperX Savage. To the right is the Patriot Ignite. They differ in flash memory types used, available capacities, and the stated performance specs vary slightly among them. Today we'll compare them against the Neutron XT as well as a selecton of other SATA SSDs.

When you pick up a Kingston HyperX Savage SSD you have a choice of the barebones model at $122 for the 240GB model or you can pay an extra $25 for the upgrade kit which contains 2.5mm z-height adapter, a SATA 6Gb/s cable, a 2.5" to 3.5" adapter plate, Acronis True Image HD imaging software, a micro-screwdriver set, and a USB 3.0 enclosure with USB 3.0 cable.  That upgrade kit is perfect for those looking for an easy way to move their entire OS to the new SSD with a minimum of fuss.  Inside the drive is the Phison PS3110 controller with a 256MB DDR3-1600 cache and Toshiba's 19nm Toggle Mode NAND.  Hardware Canucks put the drive to the test and it shows huge improvements from the first generation, enough to put it in competition with offerings from OCZ, Intel and Crucial.  This demonstrates a faster evolution that competitors products but it does unfortunately come at a price that is a bit high compared to those competitors offerings.

Samsung 840 EVO Standalone ISO Updater Now Available

Tagged: TurboWrite, tlc, ssd, slc, Samsung, 840 evo

For those of you following the Samsung 840 EVO saga, last week we saw the release of Magician 4.6. Samsung was initially throttling downloads and firmware update rates, but those limits appear to have been lifted as of this morning. Another thing we noticed this morning was the inclusion of the standalone ISO updater for those who are otherwise unable to run the Magician software (i.e. Mac users):

EXT0DB6Q ISO.png

For those on laptops or other devices with no optical drive, I've confirmed the ISO can be used via USB if placed there with a tool such as Rufus.

Note to Linux users:

There was an early report of complications from a user who was running a full disk fstrim during boot, where that operation was causing errors (corrected once that operation was disabled). It should be noted that full disk TRIM operations are redundant so long as the OS is issuing TRIM on-the-fly during regular file moves / deletions. This may be an issue with queued TRIM handling of the new 840 EVO firmware. If not reproduced / corrected by Samsung, the Linux devs may be able to add this firmware revision to the queued TRIM blacklist to possibly fix the problem on their end.

Note to mSATA 840 EVO users:

It appears the update does not currently apply to these. I've asked Samsung about this.

Samsung Magician 4.6 and 840 EVO Firmware Released - Downloads Throttled

Subject: Storage | April 23, 2015 - 02:21 PM |
Tagged: TurboWrite, tlc, ssd, slc, Samsung, 840 evo

For those who watched last night's podcast live, I predicted that Samsung would be posting their 840 EVO Firmware and new Magician 4.6 software 'soon'. Turns out that 'soon' was actually this morning, but there's a catch - Samsung decided to limit the daily downloads:

If you went to the Samsung SSD Download Page and got the above error, don't fret, there are a few mirrors out there:

I downloaded from these three sources and at the time of this posting can confirm all three are identical to the Magician 4.6 download available from Samsung.

Once installed, you *should* be able to use Magician to update the firmware on your 840 EVO and (hopefully) see its performance come back to where it should be. There have been some reports of users unable to update, but that appears to be Samsung's servers being hammered and Magician's default / timeout is to report that you are on the latest firmware. Restarting Magician may force it to re-check and get the update.

Linux and Mac users are not yet able to update as the ISO updater has not been released for the new firmware. Those capable can update their Linux or Mac 840 EVOs connected as a secondary drive under Windows with Magician 4.6 installed. Also, if you're running Linux and happen use fstrim during boot, read this post prior to updating.

Introduction, Specifications and Packaging

Introduction:

There's been a lot of recent talk about the Samsung SM951 M.2 PCIe SSD. It was supposed to launch as an NVMe product, but ended up coming out in AHCI form. We can only assume that Samsung chose to hold back on their NVMe-capable iteration because many devices are unable to boot fron an NVMe SSD. Sitting back for a few months was a wise choice in this case, as an NVMe-only version would limit the OEM products that could equip it. That new variant did finally end up launching, and we have rounded it and the other Samsung M.2 PCIe SSDs up for some much awaited testing:

I'll be comparing the three above units against some other PCIe SSDs, including the Intel SSD 750, Kingston HyperX Predator, G.Skill Phoenix Blade, Plextor M6e Black, and more!

A philosophical look at SSD benchmarking

[H]ard|OCP will be resuming their benchmarking of SSDs in the near future and wanted to introduce both their new contributor and his thoughts on benchmarking SSDs.  These drives offer several challenges when comparing performance that are not present when benchmarking spinning rust.  For instance some controllers use compression to increase IOPS whenever possible but slow down when incompressible data is passed through the drive, providing a challenge to properly show performance comparisons to similar drives with difference or no compression whatsoever.  Read through the article to see which synthetic benchmarks will remain as well as Chris' thoughts on new tests to accurately contrast the performance of SSDs.

Introduction, Specifications and Packaging

Editor's note: We are hosting a live stream event with our friends at Intel's SSD group today to discuss the new SSD 750 Series launch and to giveaway a couple of the 400GB units as well! Be sure you stop by to ask quesitons, learn about the technology and have a chance to win some hardware!!

Introduction:

Intel has a habit of overlapping their enterprise and consumer product lines. Their initial X25-M was marketed to both consumer and enterprise, with heavier workloads reserved for the X25-E. Their SSD 320 Series was also spec'd for both consumer and enterprise usage. Their most recent SSD 730 Series was actually an overclocked version of their SSD DC S3500 units. Clearly this is an established trend for Intel, so when they dominated flash memory performance with the SSD DC P3700 launch last year, pretty much everyone following these sorts of things eagerly waited in anticipation of a consumer release.

While they were hard to find outside of enterprise supply chains, some dedicated users picked up that enterprise part for their enthusiast systems, but many were disappointed as the P3700's enterprise hardware and firmware conflicted with many consumer motherboards' BIOS, rendering it unbootable for some and causing address space conflicts for others. In short, the P3700 was a great product that simply did not function properly with most consumer motherboards. All anyone could do was wait for Intel to spin a consumer product from this enterprise part, and that day is today:

addincard.jpg

This is the add-in card version of the new Intel SSD 750 Series that brings NVMe technology and insane performance levels to consumers at a cost that is more affordable than you might think.

150401-224510.jpg

As with the enterprise variant, Intel chose to launch the SSD 750 Series in the familiar HHHL PCIe x4 form factor as well as a 2.5" SFF-8639 packaging. The 2.5" model contains the exact same set of components, just rearranged into a smaller device.

150401-224548.jpg

Despite being 2.5", this is not a SATA device. While the connector may look similar, it is *very* different:

SFF-8639.png

As you can see above, SFF-8639 further extends on the familiar SATA power and data connections, which had already been extended a few times to add additional SAS data lines. The new spec adds a complete row of pins on the back side of the connector to support four lanes of PCIe. This means the SFF variant of the SSD 750 will perform identically to the PCIe half-height card version. Since SFF-8639 was born as an enterprise spec, one question remains - how do you connect it to a consumer desktop motherboard? Well, desktop motherboards are coming with M.2 ports that can support up to PCIe 3.0 x4, so all you really need is a simple way to get from point A to point B:

150401-230518.jpg

Pictured above (left) is the ASUS 'Hyper Kit' adapter PCB, which was sampled to us with their new Sabertooth X99 motherboard just for testing these new 2.5" devices. The connector you see at the right may look familiar, as it is an internal Mini-SAS HD (SFF-8643) cable commonly used with high end SAS RAID cards. Intel is basically borrowing the physical spec, but rewiring those four SAS lanes over to the PCIe pins of the SFF-8639 connector at the other end of the cable.

Samsung's 850 EVO now comes in M.2 flavour too

As Al's review of the 850 EVO exists in a cat like superposition of being biased both for and against Samsung, perhaps you would like a second opinion.  That is where The Tech Report's review comes in handy, which was published just a few short hours ago.  Their findings were perfectly in line with the others, exactly the same performance as the 2.5" drives but in a nice bite sized form factor.  The only drawback is the size, the new M.2's are missing the 1TB model at the moment.

"Samsung's 850 EVO SSD debuted in December inside the usual 2.5" case. Now, the drive is spreading to smaller mSATA and M.2 form factors. We've examined the new drives to see how the mini lineup compares to its full-sized forbear."

Introduction, Specifications and Packaging

Introduction:

Following the same pattern that Samsung led with the 840 Pro and 840 EVO, history has repeated itself with the 850 Pro and 850 EVO. With the 850 EVO launching late last year and being quite successful, it was only a matter of time before Samsung expanded past the 2.5" form factor for this popular SSD. Today is that day:

150330-182303_DxO.jpg

Today we will be looking at the MSATA and M.2 form factors. To clarify, the M.2 units are still using a SATA controller and connection, and must therefore be installed in a system capable of linking SATA lanes to its M.2 port. As both products are SATA, the DRAM cache based RAPID mode included with their Magician value added software is also available for these models. We won't be using RAPID for this review, but we did take a look at it in a prior article.

Given that 850 EVOs use VNAND - a vastly different technology than the planar NAND used in the 840 EVO, we suspect it is not subject to the same flash cell drift related issues (hopefully to be corrected soon) in the 840 EVO. Only time will tell for sure on that front, but we have not see any of those issues present in 850 EVO models since their launch.

Samsung sampled us the M.2 SATA in 120GB and 500GB, and the MSATA in 120GB and 1TB. Since both are SATA-based, these are only physical packaging differences. The die counts are the same as the 2.5" desktop counterparts. While the pair of 120GB models should be essentially identical, we'll throw both in with the results to validate the slight differences in stated specs below.
