Great news flash fans, Intel will be increasing the storage density of SSDs quite significantly over the next few years. They will be using the 3D NAND technology we have just been introduced to to stack flash memory with 32 planar layers for 32GB per cell with MLC and 48GB per cell if TLC flash is used. This increased density could lead to 10TB SSDs by 2017 as well as mobile devices with 1TB of local memory that runs at higher speeds than the current generations as well. As The Register noted this will have to be accompanied by price reductions as at $1.00/GB no one would even dream of a 10TB drive and even at $0.50 it would be far too expensive. Perhaps Ryan's dreams of low cost flash storage are not as far out there as some seem to feel, indeed he may not be aiming low enough for price per GB. You can also get a peek at what Samsung, Hynix and Sandisk will be up to in the same article.
"IMFT, Intel Micron Flash Technologies, a partnership between Intel and Micron, has a 3D MLC NAND technology, which will be used to build 10TB SSDs in two years."

Introduction, Specifications and Packaging
In recent years, Plextor has branched beyond their renowned lines of optical storage devices, and into the realm of SSDs. They have done fairly well so far, treading carefully on their selection of controllers and form factors. Their most recent offerings include the M6S and M6M (reviewed here), and are based on Marvell controllers coupled with Toshiba flash. Given that the most recent Marvell controllers are also available in a PCIe variant, Plextor also chose to offer their M6 series in PCIe half height and M.2 form factor. These last two offerings are not simply SATA SSDs bridged over to PCIe, they are natively PCIe 2.0 x2 (1 GB/s), which gives a nice boost over the current SATA limit of 6Gb/sec (600 MB/sec). Today we are going to kill two birds with one stone by evaluating the half-height PCIe version:
As you can see, this is nothing more than the M.2 version on a Plextor branded interposer board. All results of this review should be identical to the bare M.2 unit plugged into a PCIe 2.0 x2 capable M.2 port on either a motherboard or mobile device. Note that those devices need to support the 2280 form factor, which is 80mm in length.
Here's the M.2 version installed on an ASUS X99-Deluxe, as tested by Morry.
Introduction, Specifications and Packaging
At that time we only knew that Phison was going to team up with another SSD manufacturer to get these to market. We now know that manufacturer is Corsair, and their new product is to be called the Neutron XT. How do we know this? Well, we've got one sitting right here:
While the Neutron has not officially launched (pricing is not even available), we have been afforded an early look into the performance of this new controller / SSD. While this is suspected to be a cost effective entry into the SSD marketplace, for now all we can do is evaluate the performance, so let's get to it!

Since we reviewed the Intel SSD DC P3700, many of you have been drooling over the idea of an 18-channel NVMe PCIe SSD, even more so given that the P3500 variant was to launch at a $1.50/GB target price. It appears we are getting closer to that release, as the P3500 has been appearing on some web sites in pre-order or out of stock status.
ShopBLT lists the 400GB part at $629 ($1.57/GB), while Antares Pro has an out of stock listing at $611 ($1.53/GB). The other two capacities are available at a similar cost/GB. We were hoping to see an 800GB variant, but it appears Intel has stuck to their initial plan. Here are the part numbers we’ve gathered, for your Googling pleasure:
- 400GB: SSDPEDMX400G401
- 1.2TB: SSDPEDMX012T401
- 2TB: SSDPEDMX020T401
2.5” SFF-8639 (*not SATA*):
- 400GB: SSDPE2MX400G401
- 1.2TB: SSDPE2MX012T401
- 2TB: SSDPE2MX020T401
We did spot a date of December 12th in an Amazon listing, but I wouldn't count that as a solid date, as many of the listings there had errors (like 10 packs for the price of one).

Tagged: Intel, ssd, dc s3500, M.2
Today Intel refreshed their Datacenter Series of SSDs, specifically their DC S3500. We have reviewed this model in the past. It uses the same controller that is present in the S3700, as well as the SSD 730 Series (though it is overclocked in that series).
The full line of Intel Datacenter SSDs (minus the P3700). DC S3500 is just right of center.
Todays refresh includes higher capacities to the S3500, which now include 1.2TB and 1.6TB on the hign end of capacity. This suggests that Intel is stacking 20nm dies as many as 8 to a package. IOPS performance sees a slight penalty at these new higher capacities, while maximum sequentials are a bit higher due to the increased die count.
Also announced was an M.2 version of the S3500. This packaging is limited to only a few capacity points (80GB, 120GB, 340GB), and is p;rimarily meant for applications where data integrity is critical (i.e. ATM's, server boot partitions, etc).
A standard press blast was unavailable, but full specs are listed after the break.
Introduction, Specifications and Packaging
G.Skill is likely better known for their RAM offerings, but they have actually been in the SSD field since the early days. My first SSD RAID was on a pair of G.Skill Flash SSDs. While they were outmaneuvered by the X25-M, they were equipped with SLC flash, and G.Skill offered them at a significantly lower price than the Samsung OEM units they were based on.
Since those early days of flash, G.Skill has introduced a few additional models but has not been known as a major player in the SSD market. That is set to change today, with their introduction of the Phoenix Blade PCIe SSD:
If you're eager to know what is inside or how it works, I'll set your mind at ease with this brief summary. The Phoenix Blade is essentially an OCZ RevoDrive 350, but with beefier specs and improved performance. The same SandForce 2281 controllers and Toshiba flash are used. The difference comes in the form of a smaller form factor (half height vs. full height PCIe), and the type of PCIe to SATA bridge chip used. More on that on the disassembly page.

Tagged: ssd, Optimization Guide
Tech ARP have updated their handy SSD Optimization Guide which covers a variety of ways to ensure that your SSD has a long life and offers you the best possible performance while it works for you. Many of the tips such as enabling AHCI mode in your BIOS before installing an OS are obvious to even an SSD newbie but not everyone will be familiar with their GUID Partition Table or proper partition alignment. The guide is a handy reference for users old and new to make sure that your brand new SSD is performing up to specification.
"Modern SSDs use a mix of techniques and technologies like overprovisioning of memory cells, wear levelling, a write combine buffer (or on-the-fly data compression), and the Trim command or automatic garbage collection to maintain performance and extend the lifespan of the flash memory cells. However, there's only so much they can do."

Given that we are anticipating a launch of the Samsung 850 EVO very shortly, it is a good time to back fill on the complete performance picture of the 850 Pro series. We have done several full capacity roundups of various SSD models over the past months, and the common theme with all of them is that as the die count is reduced in lower capacity models, so is the parallelism that can be achieved. This effect varies based on what type of flash memory die is used, but the end result is mostly an apparent reduction in write performance. Fueling this issue is the increase in flash memory die capacity over time.
There are two different ways to counteract the effects of write speed reductions caused by larger capacity / fewer dies:
- Reduce die capacity.
- Increase write performance per die.
Recently there has been a trend towards *lower* capacity dies. Micron makes their 16nm flash in both 128Gbit and 64Gbit. Shifting back towards the 64Gbit dies in lower capacity SSD models helps them keep the die count up, increasing overall parallelism, and therefore keeping write speeds and random IO performance relatively high.
In conjunction with Dell World, LiteOn has announced their new EP1 M.2 PCIe SSD:
Designed primarily for enterprise workloads and usage, the EP1 sports impressive specs for such a small device. Capacities are 480 and 960GB, random 4k IO is rated at 150k/44k (R/W), sequentials are as high as 1.5GB/sec, and max latencies are in the 30-40 us range (this spec is particularly important for enterprise OLTP / transactional database workloads). Given the enterprise specs, power loss protection is a given (and you can see the capacitors in the upper right of the above photo). Here are the full specs:
It should be noted that larger PCIe-based SSDs are rated for greater than the 1 drive write per day of the EP1, but they are also considerably larger (physically) when compared to the M.2 EP1. As an additional aside, the 960GB capacity is a bit longer than you might have seen so far in the M.2 form factor. While the 480GB model is a familiar 2280 (80mm long), the 960GB model follows the 22110 form factor (110mm long). The idle power consumption seems a bit high, but enterprise devices are typically tuned for instantaneous response over idle wattage.

Thanks to an updated SKU list and some searching, we've come across some initial photos, specs, and pricing for the upcoming Samsung 850 EVO.
You may have heard of an 850 EVO 1TB listing over at Frys, but there's actually more information out there. Here's a quick digest:
- Memory: 3D VNAND
- Read: 550MB/sec
- Write: 520MB/sec
- Weight: 0.29 lbs
Pricing (via Antares Pro listings at time of writing):
- 120GB (MZ-75E120B/AM): $100 ($0.83 / GB)
- 250GB (MZ-75E250B/AM): $146 ($0.58 / GB)
- 500GB (MZ-75E500B/AM): $258 ($0.52 / GB)
- 1TB (MZ-75E1T0B/AM): $477 ($0.48 / GB)
In addition to the above, we saw the 1TB model listed for $500 at Frys, and also found the 500GB for $264 at ProVantage. The shipping date on the Frys listing was initially November 3rd, but that has since shifted to November 24th, presumably due to an influx of orders.
We'll be publishing a full capacity roundup on the 850 Pro in anticipation of the 850 EVO launch, which based on these leaks is imminent.
