According to hardware guru Ice Universe, who normally specializes in mobile leaks, Samsung will be launching the Pro SSD within two months. Of course, anyone can tweet such a timeline, but we believe there is some merit to the statement. June 10, By now, there are quite a few manufacturers making PCIe 4. Well, it doesn't have a product on the consumer market yet. However, we did see the Pro at CESand it wouldn't come as too much of a surprise to see a release around the time where Computex would normally have taken place -- which is right about now.

Alas, the Coronavirus pandemic may well have lead to delays in manufacturing, impacting the release date of this product. What makes it more urgent for Samsung to release a product out is the release of the AMD B chipset. This platform brings PCIe 4. The new PCIe 4. This is in part due to more advanced controller technology, allowing the SSD to leverage the full bandwidth which four lanes of PCIe 4. June 10, By now, there are quite a few manufacturers making PCIe 4.

Topics Storage. See all comments 4. Any word on whether there will be a 2TB or more version? But the question is will anyone other than prosumers and professionals be able to afford it? Gone is the age of Samsung drives being cheaper and better than all the other competitors, now there is much more viable variety for sometimes far less than Samsung charges.

About time. Even a relatively small Mb system drive with a large secondary will preform better than other drives. I can now start planning my AMD high core count workstation system. Alvar Miles Udell said:.Is your SSD turning in lower benchmark numbers than what its spec sheet promises?

It's possible that your motherboard's chipset or an add-in storage controller is to blame. But do those results really mean anything in an enthusiast's desktop PC? Which chipset does your motherboard employ? More specifically, even if your storage controller supports the very latest standards, is it as fast as the other controllers out there with similar specifications from competing vendors?

We've spent plenty of time digging into the performance attributes of SSDs. Now, we want to have a look at how different south bridges and standalone controllers affect storage performance.

In an SSD review, you'd see us use a bunch of different drives as comparison points. Here, though, we want to stick with one and have that serve as a stake in the ground, facilitating consistent throughput to our various controllers. Samsung's GB Pro is one of the highest-end SSDs we have in the lab, and the company sent out one to each of our editors for use as Tom's Hardware's reference through Topics AMD.

See all comments It's a shame that AMD went for quantity over quality. As a side note, when can we see an usb3. I was surprised to see intels 3gbs outpace marvels 6bps controllers in many benchmarks. Just goes to show you that not all SATA controllers are created equal.

The one thing the article didn't say, which it should, is that Marvell controllers are garbage. Notice how often the P55 matches or beats one of the Marvell 6gbit controllers. The PCIe x1 link issue is bad enough, but sometimes even having a proper connection doesn't help their performance. Also not mentioned is SSD reliability. The only time I've ever had problems with an SSD were when it was connected to a Marvell controller eg.

I would like to see if there is any performance difference when each of the 3rd party controllers are tested on the available platforms. There is one very significant piece of information that is not included in this article.Featuring an industry-leading capacity of up to eight terabytes TB1 the new SSD delivers an uncompromising mix of speed, storage capacity and reliability for mainstream and professional PC users. In the past, consumers have had to choose between SSDs — which provide superior performance — and HDDs, which traditionally offer greater capacity.

The renewed Data Migration and Magician 6 softwares provide a host of improved and added features, enabling users to upgrade, manage and optimize their SSDs with greater ease. In addition to the industry-leading capacity and performance, the QVO provides an exceptional endurance rating of up to 2, terabytes written TBWor a three-year limited warranty 5.

Please Enter a Profession. Newsroom's Privacy Policy.From our perspective, the much more affordable EVO will be the more interesting product. Samsung hasn't shared many architectural details of the new Phoenix controller, but like its earlier NVMe controllers it uses a PCIe 3.

Like the previous generation Polaris controller, there are five CPU cores, with one dedicated to host-side communications. This is a substantial bump for anyone looking at Samsung's latest EVO drives. This prevents the smaller models from suffering the performance penalties that come with the reduced parallelism of having fewer NAND flash chips on the drive.

The Samsung Phoenix controller introduces a nickel-coated heatspreader, and the EVO retains the copper foil layer in the label on the back of the drive that was introduced with the generation, but there are no more serious cooling measures on the drive.

Samsung claims the units are even less susceptible to thermal throttling thanks to a combination of higher performance before they throttle and a slightly higher temperature limit. As with almost all of our testing, this review sticks to just the NVMe drivers included with the operating system. We have generally not found vendor drivers to offer compelling performance improvements, though they have historically enabled some extra features that Microsoft's drivers don't allow for. In the near future, our SSD testbed will be updated with the OS and microcode patches for the Meltdown and Spectre vulnerabilities, so it is clear to point out that this review does not contain them yet.

Since these updates will have enough of an impact on benchmark results to make new results incomparable to old results, I am also taking the opportunity to make some minor updates to the synthetic test suite. The outgoing test suite will also be run on several drives with the patched system to measure the performance impact of the patches.

There will be several more SSD reviews over the next few weeks using benchmark results that have already been collected before the new test suite debuts.

As you may know, NAND flash memory can sustain a limited number of write operations. This can lead to the conclusion that a NAND flash cell can sustain up to write cycles, and that an SSD drive can actually survive more than a thousand complete rewrites regardless of other conditions.

This, however, is not fully correct. Certain usage conditions and certain types of load can wear SSD drives significantly faster compared to their declared endurance. Major SSD manufacturers such as Crucial and Samsung are offering 5-year limited warranties to their recent models. The manufacturers specify the maximum amount of data that can be written to an SSD drive during the warranty period.

This TechReport test is fairly old, but their findings are consistent with the recent ongoing tests by 3DNews. Long-term testing of multiple SSD models performed by 3DNews suggests that even mid-range SSD drives can be overwritten many thousand times before their flash memory starts showing signs of degradation.

Speaking of wear, each write operation slightly damages a NAND cell. One can still write data in worn out cells; the data can be read back successfully immediately after write. However, the cells will leak charge, and will only retain data for some very limited time. We power off the SSD drive and let it sit for two days, then power it back on and read the cell.

The time a NAND cell can retain charge after a certain number of programming cycles is a major criteria when calculating the endurance rating. Most NAND flash manufacturers specify that cells must retain charge for at least two weeks at high temperatures e.

This time is significantly longer at home temperatures. During the specified retention period some cells are allowed to leak charge, but such bit errors must be correctable via ECC. Two weeks is scary; in real life, reputable manufacturers use NAND chips that significantly exceed the minimum specifications. There is never lack of demand for low-cost sub-standard NAND chips. Third-tier manufacturers such as Kingspec, Smartbuy or Silicon Power purchase such inexpensive chips in bulk, producing low-cost SSD drives with varying reliability.

High temperatures negatively affect the ability of NAND flash to retain charge. As the temperature increases, the electrons escape the floating gate faster. This cell loses charge, and the data becomes unreadable. ACELab performed a controlled test in an attempt to verify the effect of high temperatures on the ability of NAND cells to retain charge.

Heated beyond this temperature, the chip was physically damaged. For this reason, some experts prefer using heated wires to cut chips off the PCB instead of unsoldering. While we only need 3. The higher voltage is required to place electrons in the NAND cell. As higher voltages are applied, the insulating layer between cells starts degrading, allowing more electrons escape as the time passes.

The manufacturer was overly optimistic when estimating lifespan of the then-new TLC flash cells. The cells degraded significantly faster than planned. Many users lost data from unpowered Evo drives after only 30 days of storage. Needless to say, the fix negatively affected real-life endurance of the drives, wearing cells much faster than planned. There are other technologies that are used to increase lifespan of the NAND cells.

SLC cache is extremely effective if the SSD drive is used in environments with a frequent writes of small data blocks e. SSD drives are designed to sustain multiple overwrites of its entire capacity.Announced Tuesday, this is the new top capacity available, superseding a still-new flock of 4TB models.

Samsung sent us the 2TB version for testing. A standard 2. The drives seemingly allocate about 4. Samsung bundles its Magician software, which provides control of overprovisioning the amount of NAND set aside for replacement of dead cellssecure erase, and diagnostics.

CrystalDiskMark 6 measured the drive as matching the speed of the competition. Shorter bars are better. The 1TB QVO would no doubt have run out about the same time, but it probably still would have turned in a slightly faster score than the QVO because of its faster write rate, off cache.

As you can see below, the QVO was faster than its predecessor, but still far slower than the other drives. You can see in the capture below exactly why the Samsung QVO drives are so much slower writing the extra large GB file.

Once in a blue moon, if at all.

Does Your Storage Controller Affect The Performance Of An SSD?

The DRAM makes the drive very responsive while running an operating system, with its myriad small file calls. But 8TB?

Come on now. That's pretty sweet. Just be aware of the severe dropoff in speed when writing outside of the cache. However, while it's faster than its predecessor, its write performance after running out of cache is extremely weak. At a Glance. Specs and pricing A standard 2.

I mean, it's not like you can just say anything online, with no supporting evidence, and have it reported as fact from just anywhere.

But that potential August launch tallies with what we've heard from our own sources recently too. Unveiled at CES in Januarywe would have expected to see the newest Samsung solid state drive generation by now. Back at the start of the year Samsung was suggesting that more information on the drive would arrive in Q2, but we're rapidly approaching the end of that particular window. The new suggested launch timing has come from UniverseIce via HWBattlea noted source of other Samsung rumours, and claims that it will mark the arrival of "the super performance of real PCIe 4.

June 10, The only PCIe 4. Well, until Phison unleashes its own new E18 controller later in the year anyways. That should already be out with SSD manufacturers to create their own firmware and drives as I type, for a prospective launch into the market in Q3… or just after the Pro. Those will likely offer higher performance than the current Phison drives, but likely with a similar price tag.

Dave has been obsessed with gaming since the days of Zaxxon on the Colecovision, and code books for the Commodore Vic 20 Death Race ! He built his first gaming PC at the tender age of 16, and finally finished bug-fixing the Cyrix-based system around a year later. When he dropped it out of the window. Thankfully it's a lot easier to build a gaming rig now there are no motherboard jumper switches, though he has been breaking technology ever since… at least he gets paid for it now.
