TSSDR PCIE TEST BENCH AND PROTOCOL
SSD Testing at TSSDR differs slightly depending on whether we are looking at consumer or enterprise SSDs. For consumer SSDs, our goal is to test in a system that has been optimized with our SSD Optimization Guide, although CPU C States have not been changed at all. Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch. We even provide links to most of the benchmarks used in the report.
Enterprise testing is significantly different as we explore performance in steady state, explore drive latency, and do our best to follow SNIA test protocol. For the Toshiba HG5d SATA M.2 SSD, this SSD is marketed as a client device so we are going to follow our typical consumer SSD testing protocol.
This new PCIe Test Bench build was the result of some great relationships and purchase; our appreciation goes to be quiet, Corsair, Crucial, Intel, EVGA and InWin for their support in our project. Our choice of components is very narrow, in that, we choose only what we believe to be among the best available and links are provided to each that will assist in hardware pricing and availability, should the reader be interested in purchase.

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, QuickBench, Crystal Disk Info, Crystal DiskMark, AS SSD, Anvil Storage Utilities,and PCMark Vantage. In consumer reports, we prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and, also, to provide validation to results already obtained.
For our testing today, we will be using the BPlus M2PS Dual M.2 (NGFF) SSD to SATA Adapter for our testing of the Toshiba HG5D M.2 SSD. It is interesting to note that, just as a native M.2 PCIe SSD can’t be switched off in a system for a SATA M.2 PCIe SSD, the same goes for adapters and separate adapters must be utilized for each type of M.2 SSD.
This adapter uses the PCIe lanes strictly for power, while the SATA cable connects from the adapter to the Intel port of the motherboard.
QuickBench is a recent addition to our tool chest and we use it as it does a great job validating ATTO scores by measuring the transfer speeds of increasingly larger files. For our purposes, we have tested in standard and extended file sizes. Performance highs are displayed in blue while lows are displayed in brown.
Initial benchmark results of 507MB/s read and 488MB/s write is a decent start but the most encouraging result in these two benchmarks is the 4K random write result of 93MB/s.
hmm… too slow. Really M.2(NGFF)’s release?
It’s likes only swapping SATA6G and PCIe I/O.
I have to wonder about a few things:
1. Why is SATA3 still used when SATAexpress (12Gbps) is already here? SATA3 has been around for several years and it’s already showing its age…it’s the reason that SSDs are bottle-necked at around 550MB/s.
2. Even when SATA3 makes way for SATAexpress, it will be already outdated, as 12Gbps (1.5GB/s) can already be surpassed by high-end SSD, which can reach over 2.5GB/s.
3. The claim that SATA3 SSD are already fast enough for most consumers is just bullshit.
In computers, the name of the game is SPEED. Anyone trying to stop/uphold the evolution is only doing consumers a dis-service.
4. Besides SATA and PCIe, there’s also SAS, which currently tops at 12Gbps (same as SATAexpress). SAS is usually reserved for workstations and servers. Why hasn’t SAS trickled down to consumer PCs? Why have a different standard, if SAS has some advantages over SATA? Is it merely to charge extra for a more “professional” port?
5. What about that NAND flash that can sit in a RAM slot and have the best & fastest connection with the least latency? It’s faster than SATA3, SATAespress, SAS12 and even faster than PCIe x8.
For example, Diablo MCS:https://www.extremetech.com/computing/162944-diablos-memory-channel-storage-tech-will-deliver-terabytes-of-ram-using-nand-flash
What the hell are you talking about? SATA Express is hardly “here”. I’d love for you to show me some laptops that contain SATA Express drives. Yea, didn’t think so.
And SAS? Really? If SAS was going to make it into mainstream computers, it would have happened AGES ago.
As for your shot at this article (and site), you will be hard pressed to find another site dedicated to SSDs with as much history as this forum/blog. PCIe is where it’s at, bro-sees.
SATA express (SATA 3.2) is coming, and I believe will be in consumer machines before the end of this year. My guess is that the only reason for its existence is support for DEV-SLP, which PCIe devices do not support. DEV-SLP is important for laptops where battery life is crucial.
I love this site, and fully support it. It brings very interesting information, which is not usually found anywhere else.
My wish was simply that manufacturers switch to PCIe 3.0 x4 (or even x8) to enable the full potential of SSDs. The SATA standard is simply getting in the way.
Manufacturers will need to find a solution to bring PCIe power consumption down.
It could be that SATA express storage will be used mainly on battery-powered devices, and PCIe 3.0 storage will be used mainly on desktops where more performance is more important than saving power.
1. SSD are already too fast for current Operating Systems, which still have many depdendencies on timing hard-coded somewhere. Bottleneck is 1. OS 2. Drivers 3. Applications 4. “Protein Interface” i.e. human
2. SSD are already sacrificing most important characteristic – RELIABILITY and DURABILITY chasing still unnecessary performance.
“… chasing still unnecessary performance.”
Awwww. Eric, that’s so cute. Did you just get your first leapfrog computer? Well, at least you haven’t upgraded to SSD yet. That goes right up there with: “640k memory should be enough for anyone.” Only you actually said it — after it was outdated! I hope you realize that the most constrictive bottleneck in data transfer rates has been the hard drive for a looooong time. That’s why starting a program used to take 20 seconds instead of 2 and why booting used to take 60 seconds instead of 6. Now run along and go upgrade your computer with a new SSD drive. You will swear you bought a new computer… from the future!
My bad… Antey, Not Eric. Very sorry for the mixup, Eric.
The last slide is interesting for me in particular, because check out that Plextor M5M beating out everything but the XP941 (no surprise there). When I sold my maxed-out Mac mini, so I could afford my new BTO iMac with PCIe SSD, I was forced to use another mini in the meantime while waiting for its arrival, but I had sold my 250GB 2.5″ Samsung 840 EVO SSD along with it.
Luckily, I had already ordered and received an mSATA-to-2.5″ SATA converter, so I took out my 128GB Plextor M5M that I had purchased for caching purposes in my Drobo 5D, and put it in the Mac mini. I was BLOWN AWAY! It has a Marvell controller, so the performance difference between the 128GB and 256GB capacities is quite negligible, but this tiny little mSATA SSD beats out the Samsung 840 EVO, the Intel 520 Series, the OWC Extreme and every SSD that I’ve owned prior. I can’t wait to see how much faster the XP941 in the new iMac is as compared to the amazing performance of the Plextor M5M series. I just wanted to mention it, because I really didn’t expect that!
P.S.: Plextor is coming out with its next-gen. M6 series shortly, so I would only buy an M5 series variant, if you can find a crazy awesome deal for it. 😉
Where can you buy this? RamCity doesn’t have it :/
Unfortunately I am not aware of anywhere for retail sales. RAMCity would have been my best guess as well. It is a M.2 client (non-retail) SSD.
This is pretty much the best SSD for a Samsung Ativ Book 9 940X3G eh?
It is a SATA M.2 looking @:
Yup…it seems to be a SATA M.2. Availability is the next issue. At retail, I have ONLY seen Intel M.2 SSDs listed on Amazon and Newegg in very small amounts. I might ask RAMCity if they can get you ANY SATA M.2. What exactly are you looking for, simply a larger capacity?
512GB and the fastest possible .. whatever options then can provide would be great… I’m sure all SATA M.2 owners would be interested
This is actually a bit amusing because, when mSATA first came out, i was the first to tell manufacturers to get it out to the retaiul market. Most declined and stated that there was no need for M.2 just yet, failing to think about the millions of Lenovo notebooks that contained them. The result was a vry large shortage of demand where, just like now, you have to keep your eyes open for wherever they pop up fast. I have been watching the 80 and 300GB Intel M.2 530 on Amazon and newegg for a few days and they are gone fast!
I will keep an ear open Mike!
When my AB9+ arrives soon its 256GB… so I would need a 512GB to make it worth while… now doing a clone from one to the other is going to be interesting, how to do it
