Review Toshiba XG6 M.2 NVMe SSD: Higher Density and Improved Efficiency

Toshiba XG6 M.2 NVMe SSD Review: Higher Density and Improved Efficiency 

Highlights and Specifications 

SSDs are relentlessly dislodging HDDs in the buyer advertise, however advance is moderate in a few zones. Truly, more scratch pad are accompanying SSDs naturally, yet selection in OEM work area PCs has been slower. Today we investigate Toshiba's most recent OEM-arranged SSD. Toshiba outlined the XG6 for work area PCs, versatile frameworks, installed frameworks, and even server farms.

That implies the XG6 could control your next workstation or pre-constructed PC. All the more vitally for us, the XG6 accompanies Toshiba's new 96-Layer TLC BiCS streak that will before long power the most current fan class SSDs from numerous sellers. The new blaze guarantees more execution and productivity at a lower value point, and in view of our testing, it conveys

As said, the Toshiba XG6 is the business' first SSD with Toshiba's most recent 96-Layer 3D TLC streak. Toshiba's new amazing a 40% limit increment over the organization's past gen 64-layer streak. The expanded thickness results in bring down assembling costs, which thusly enables Toshiba to be more forceful with its SSD evaluating.

Toshiba's new blaze bolsters Toggle 3.0 paces (667-800 MT/s), which implies its program and read dormancy is lower than the organization's past gen Toggle 2.0 glimmer (400 MT/s). Toshiba's new blaze isn't exactly as quick as Samsung's most recent 256Gbit 3D streak that backings Toggle 4.0, however Toshiba's expanded limit is the enormous fascination.

We typically anticipate that new glimmer will be combined with another SSD controller, yet the XG6 utilizes indistinguishable controller from the XG5. Toshiba's firmware and blaze upgrades, refresh to the NVMe 1.3a spec, and spotlight on enhanced power effectiveness have yielded huge changes, however.

Toshiba's XG6 utilizes an upgraded SLC compose cradle to give higher successive compose speeds than the XG5 and up to double the execution in irregular workloads. That is a shockingly enormous change considering the SSD utilizes a similar controller, yet it's reasonable the benefits of the considerably speedier 96-layer streak are radiating through.


The Toshiba XG6 comes in three limits of 256GB, 512GB, and 1TB. The drive presents to 3.18/2.96 GB/s of successive read/compose throughput and up to 355,000/365,000 arbitrary read/compose IOPS. Toshiba estimates execution when the information arrives in the SLC reserve, a quick cradle that assimilates approaching information, which implies these estimations are crest esteems. We recorded ~1.6 GB/s of throughput when information overflowed to the local TLC streak. That is in reality extremely aggressive contrasted with different SSDs.

Power utilization is a standout amongst the most critical contemplations for OEM gadgets. Toshiba's new glimmer includes a 1.2V I/O rating. That is 33% lower than the past gen's 1.8V, which likens to huge power investment funds. The XG5 is evaluated for 4.2W of dynamic power utilization and tumbles to only 3mW in its most reduced power state (L1.2). We'll put those cases under a magnifying glass.

The XG5 is an OEM-situated item, so evaluating differs in light of the client. Toshiba likewise offers models that help either TCG Pyrite or TCG OPAL 2.01 encryption. Toshiba backs the XG6 with a five-year guarantee, however OEMs have wide scope by they way they pass that guarantee down to their clients. Toshiba didn't give us a continuance rating in light of the fact that the OEM likewise manages it.

A Closer Look 

The XG6 arrives in a M.2 2280 S2 single-sided frame factor with the Toshiba TC58NCP090GSD SSD controller. This controller speaks with the host over a PCIe 3.1a x4 interface with the NVMe 1.3a convention.

The 1TB XG6 has a 512MB Nanya DRAM support. Most SSDs have a 1MB-to-1GB DRAM-to-NAND proportion, however ongoing SSD outlines seem to flag a move to bring down proportions. For example, the 1TB Intel 660p just accompanies 256MB of DRAM.

The XG5 packs 1TB of capacity into only two blaze bundles. That likens to 953GB of usable space after you design the drive in Windows. PC producers are strongly centered around diminishing weight, and the XG6's 7.3 grams is considerably more acceptable than the regular 40-70 grams for a SATA SSD.

Performance Results 

Correlation Products

We incorporated the Samsung 970 EVO and Pro in our correlation pool. These elite (and prevalent) SSDs highlight Samsung's 64-Layer V-NAND in TLC and MLC flavors, separately. We additionally tossed in the WD Black, Plextor M9Pe, and the RD400. At last, we incorporated the Intel 660p and the Crucial MX500. The Intel 660p is another NVMe SSD in light of QLC NAND, yet it comes at SATA evaluating. The MX500 is a standout amongst other SATA SSDs available.

Trace Testing – PCMark 8 Storage Test 2.0 

PCMark 8 is a follow based benchmark that utilizations Microsoft Office, Adobe Creative Suite, World of Warcraft, and Battlefield 3 to quantify the execution of capacity gadgets in true situations.

The Toshiba XG6 positioned second to the Samsung 970 Pro. That is a significant great accomplishment considering the 970 Pro is a MLC-based execution situated item for experts while Toshiba's XG6 is a standard TLC-based drive for standard buyers.

Diversion Scene Loading - Final Fantasy XIV 

The Final Fantasy XIV StormBlood benchmark is a free genuine diversion benchmark that effortlessly and precisely thinks about amusement stack times without the mistake of utilizing a stopwatch.

As opposed to the amazing outcome we saw in PCMark 8, the XG6 fell into last place among the SSDs amid the Final Fantasy diversion stacking benchmark. Indeed, even the SATA-based Crucial MX500 gave better execution, but by the slimmest of edges. The XG6 beat the 2TB HDD by 15 seconds.

Tranfer Rates – DiskBench 

We utilize the DiskBench stockpiling benchmarking instrument to test document exchange execution with our own particular custom 50GB square of information. Our informational index incorporates 31,227 documents of different kinds, similar to pictures, PDFs, and recordings. We duplicate the documents to another organizer and afterward catch up with a read trial of a recently composed 6 GB record.

The Toshiba XG6 fared well amid our 50GB blended read/compose document exchange workload. The drive arrived at the midpoint of 339 MB/s, which positioned behind the Samsung 970 Series and WD Black however outflanked the RD400, 660p, and shockingly, the Plextor M9Pe.

The rankings took after a comparable example amid the 6GB document read test. Because of the benefits of the PCIe transport and the effective NVMe convention, almost all NVMe SSDs exceed expectations amid read-driven workloads. We recorded a 4X change over the MX500 SATA SSD and about a 20X change over a standard 3.5" HDD.

SYSmark 2014 SE 

Like PCMark, SYSmark utilizes genuine applications to gauge framework execution. SYSmark takes things substantially further, in any case. It uses fourteen unique applications to run genuine workloads with genuine informational collections to quantify how by and large framework execution impacts the client encounter. BAPCo's SYSmark 2014 SE introduces a full suite of uses for its tests, which incorporates Microsoft Office, Google Chrome, Corel WinZip, a few Adobe programming applications, and GIMP. That additionally makes it an awesome test to quantify the measure of time it takes to introduce generally utilized projects after you introduce a crisp working framework.

We introduced SYSmark 2014 SE to the XG6 in just shy of 15 minutes, tying the Plextor M9Pe for second place. The XG6 scored a generally low (at any rate for a NVMe SSD) 1,645 responsiveness focuses. That trailed the other NVMe SSDs and scarcely beat the SATA-based MX500. The XG6 will furnish end clients with a smart and responsive experience, however it shows up it could profit by more firmware tuning.


ATTO is a straightforward and free application that SSD merchants regularly use to allocate successive execution particulars to their items. It likewise gives us knowledge into how the gadget handles diverse document sizes.

The Toshiba XG6 isn't as streamlined for littler documents as alternate SSDs in our examination pool, which may be a factor in its generally low SYSmark score. The XG6 increase to 3.2 GB/s gradually as it worked through the little documents in the read workload. A similar example rose with little records amid the compose test, however the distinction between different SSDs wasn't as expansive. The XG6 crested at 3 GB/s amid the compose test yet tumbled to 1.57 GB/s at the 8MB document measure as the workload spilled from the SLC reserve into the local TLC stockpiling.

Anvil's Storage Utilities 

Blacksmith's iron's Storage Utility is an ordinarily referenced benchmark that disentangles the complex IOMETER benchmark and its fundamental Dynamo motor with a single tick programming wrapper.

The Toshiba XG6 arrived in fourth place in general behind the Samsung 970 EVO. As opposed to our perceptions in ATTO, the XG6 did well amid the read part of this test.


CrystalDiskMark (CDM) is a straightforward and simple to utilize document measure benchmarking device.

The Toshiba XG6 conveyed the normal execution aftereffects of 3.25/2.97 GB/s of consecutive read/compose throughput at a Queue Depth (QD) of 32. The XG6 conveyed 1.26/1.83 GB/s of successive read/compose throughput at QD1, which is more delegate of execution in a typical workload.

Sustained Sequential Write Performance 

Official compose determinations are just piece of the execution picture. Most SSD producers actualize a SLC store cradle, which is a quick region of SLC-customized streak that retains approaching information. Maintained compose paces can endure colossally once the workload spills outside of the SLC reserve and into the "local" TLC or QLC streak. We pound the SSDs with successive composes for 15 minutes to quantify both the span of the SLC support and execution after the cradle is immersed.

The Toshiba XG6 has a somewhat little SLC store with respect to its aggregate limit. The SLC reserve is around 10GB, so it fills in as meager as 3-4 seconds. Once the support is full, execution drops to the lower speed of the TLC streak. The XG6 fills rather rapidly, yet its compose speed stood tall at an amazing 1.5GB/s.

Power Consumption 

We utilize the Quarch XLC Programmable Power Module to pick up a more profound comprehension of intensity attributes. Sit without moving force utilization is a critical viewpoint to consider, particularly in case you're searching for another drive for your workstation. Some SSDs can devour watts of intensity out of gear while more qualified ones taste just milliwatts. Normal workload control utilization and max utilization are two different angles, however execution per-watt is more essential. A drive may expend more power amid any given workload, however achieving an assignment speedier enables the drive to drop into a sit state quicker, which at last spares control.

The Toshiba XG6's 138 MB/s of throughput-per-watt made it a standout amongst the most proficient SSDs we've tried. The XG6's 2.46W normal and 5.11W most extreme outcomes were altogether not as much as the other TLC NVMe SSDs, and a large portion of that of the MLC-based Samsung 970 EVO under load.

The XG6's sit still power utilization was additionally noteworthy. The 1.4W normal with ASPM incapacitated may appear to be high, yet it was lower than whatever is left of the superior SSDs. SATA-based SSDs are generally more productive when control investment funds highlights are incapacitated, so it wasn't amazing to see the MX500 win that test. The XG6's sit out of gear control utilization dropped to only 0.173W (173mW) when we empowered the power sparing highlights.


Toshiba's XG6 is the main M.2 SSD to utilize the organization's most recent 96-layer 3D TLC NAND. We respect the XG6's natural favorable position of speedier glimmer execution with open arms, yet this isn't a SSD you can just buy on Amazon or Newegg. Rather, the SSD will advance into workstations and other implanted frameworks over the coming a long time through OEMs and other B2B clients. We were sufficiently fortunate to get a test in our own hands to flaunt the execution to the general population, yet outsider SSD creators will before long form drives in view of a similar glimmer.

The Toshiba XG6 performed well in the vast majority of our tests. Is anything but a weighty entertainer like Intel's Optane-based drives, yet it is as yet noteworthy. The XG6 achieved the second-most noteworthy score we have seen from a blaze based SSD in the PCMark 8 test, which is awesome news for content makers.

On the other hand, the drive didn't perform so well in SYSmark 2014 SE. The XG6 beat the Crucial MX500 SATA SSD, however there was a generally extensive hole amongst it and the other standard NVMe alternatives. As opposed to PCMark 8, which tests one program at any given moment, SYSmark's responsiveness score measures the smartness of a framework while it does various diverse undertakings immediately. This test isn't the end-all-be-all proportion of execution, however is an extraordinary test to demonstrate which SSDs can stay aware of various workloads and which ones could move forward. Toshiba has likely tuned the XG6's firmware for a particular client, however it could utilize somewhat more refinement.

The Toshiba XG6 still conveys incredible certifiable outcomes in numerous normal workloads, similar to our custom record exchange test. The XG6 hit crest successive paces of 3.25/3.0 GB/s read/compose, and it even gave 1.5/1.6 GB/s of throughput when our manufactured workload spilled outside of the SLC store. That makes it a standout amongst other TLC SSDs available for expanded compose workloads. We could request a bigger powerful SLC store like Intel's 660p, however the present outline is adequate for most work area workloads. Toshiba additionally has the XG5-P, an execution situated item for OEMs, which conveys quicker supported compose speeds. Toshiba has affirmed that it will likewise invigorate that arrangement with the new 96-layer streak.

The XG6 likewise turned out to be an exceptionally productive drive. The XG6's normal of 138 MB/s of throughput-per-watt gains it the title of the most proficient SSD we have tried under load. There is still space to enhance, however. The drive expended 173mW out of gear with ASPM empowered, yet the Samsung 970 Series and Intel 660P devoured less power under similar conditions.

Generally, the Toshiba XG6 conveyed awesome execution and a portion of the best productivity measurements we've seen. The conservative M.2 2280 single-sided frame factor and support for TCG Pyrite and TCG OPAL 2.01 encryption should settle on it a prevalent decision for OEMs, particularly those that outline business-class PCs. We anticipate seeing these SSDs on our test seat in future PC and pre-fabricated PC audits, also the aficionado class SSDs that will come to advertise soon with a similar glimmer.
