Seagate IronWolf 510 SSD: How well does it perform?

NAS gear on the whole units out with the premise of offering good efficiency in a compact and simple to handle bundle whereas doing this with very modestly specified {hardware}.

This method contrasts with typical server configurations, which have massively highly effective CPUs and gigabytes of RAM. These require fixed monitoring, warmth administration, and sometimes considerably extra bodily house.

One of many downsides to the NAS method is that if heavy calls are made on its assets, and through this time, they will shortly change into overwhelmed.

Most of the business-orientated NAS designs have the choice to extend the put in RAM; however, as a result of the platforms that these machines use aren’t workstation PCs, they’re usually restricted to 6GB or 8GB in dimension.

A greater and usually less expensive method is to utilize SSD storage as an intermediate cache that sits between the system and the exhausting bodily drives, offering a way to run the exhausting drives effectively and keep system efficiency in making attempt instances.

The most recent era of NAS containers are replete with fashions that embrace M.2 slots for this function, and storage makers at the moment are addressing this rising market.

However, that is a costly alternative that should justify the acquisition value.


The Seagate IronWolf is available in 4 capacities; 240GB, 480GB, 960GB, and 1.92TB.

NVMe NAS focused expertise isn’t low-cost, which $119.99, $169.99, $319.99, and $539.99 respectively for these capacities effectively demonstrates.


The Seagate IronWolf 510 seems to be like every other M.2 NVMe storage system. And certainly, it’s attainable to mount it on an NVMe supporting motherboard or daughtercard and use it in a PC like every other NVMe drive.

The variations between this drive and a Seagate FireCuda 510, Samsung 970 EVO, or WD Blue SN550 are inner, not simply variances within the controller and NAND modules, however in the way in which that these drives are designed explicitly for NAS operations.

That stated, it nonetheless makes use of Phison NVMe SSD controller, DDR4 DRAM for caching, and TLC NAND flash because of the essential elements.

However, the particular sauce right here is that as a substitute for utilizing the standard Phison PS5012-E12 controller, this stick mounts the enterprise-class Phison PS5012-E12DC system.

This 28nm controller has the capabilities to ship as much as 3200 MB/s in Sequential Reads and 3200 MB/s in Sequential Writes, but additionally, present prolonged endurance decreased latencies, and supply constant efficiency on quite a lot of workloads.

A difficulty that it additionally addresses that makes normal NVMe drives unsuitable for NAS deployment is that it has inherent energy loss information safety.

Having the facility yanked whereas a file is partially written, leaving unresolved information packages within the cache, may simply consequence in the corruption of a NAS quantity.

The Phison PS5012-E12 controller accepts that chance, mounting further circuitry and capacitors to offer further operational time to flush RAM and buffers, ought to the worst occur.

It ought to go without saying that working a mission-critical NAS without a UPS (uninterruptable energy provide) is a dangerous enterprise. The protections within the IronWolf 510 shouldn’t be crucial; however, even within the best-managed system, unlucky occasions can happen.

One other concern of server operations is a minor glitch that corrupts information because it strikes by the system, and this platform is designed to deal with these uncommon occurrences by offering a way of chaperoning the info because it travels from the host system to NAND flash.

Most NVMe drives have an information correction scheme; however, the parities testing on this system ought to successfully forestall tender errors.

The opposite necessary function of this drive is the controllers LDPC ECC engine has been tuned to boost NAND endurance permitting the 240GB, 480GB, 960GB, and 1.92TB to have TBW (Whole Bytes Written) of 435TB, 875TB, 1,750TB, and a whopping 3,500TB respectively.

Within the IronWolf 510 brochure, it makes use of the acronym DWPD (drive writes per day) and declares that worth to be 1.

What which means is if in case you have the 960GB IronWolf 510 put in, it ought to be capable of having 960GB move by the cache drive every 24 hours and nonetheless obtain its five-year guarantee.

And the TBW numbers help that speculation.

For those who evaluate the endurance with typical desktop NVMe drives, the place a 1TB drive may need a TBW of 600TB, the IronWolf 510 has a life expectancy of at the least triple that worth.

This unit additionally comes with a 2-year Rescue Information Restoration Companies plan. However, being practical, recovering information from a standard file construction is one drawback; however, making sense of how a NAS working system would possibly utilize cache house on a drive and pulling out entire information appears an implausible train at finest.




Right here’s how the Seagate IronWolf 510 drive carried out in our benchmark checks:

CrystalDiskMark: 3022MBps (learn); 964MBps (write)

Atto:  3115MBps (learn, 256MB); 967MBps (write, 256MB)

AS SSD: 2658MBps (seq learn); 897MBps (seq write)

We examined a 1.92TB utilizing an AMD Ryzen to take a look at the platform and artificial benchmarks to entry drive efficiency. We don’t have the time or amenities for testing the TBW of this system, so these numbers should be taken in good religion.

Our rapid response to the artificial benchmarks is that the learning efficiency of this drive is suitable; however, the writing pace is slower than we had been anticipating.

In making an attempt to elucidate a writing pace of lower than 1000MB/s, this drive should keep a situation the place energy loss received be catastrophic. Due to this fact, the quantity of write information within the RAM cache can’t exceed the power of the capacitors to save that information in non-volatile NAND cells earlier than energy is totally misplaced.

We consider that Samsung discovered a technique to negate this considerably and enhance the write efficiency to round 1,430 MB/s; however, neither can provide the three,000MB/s write efficiency of client drives.

Each did higher than Synology, as it may possibly solely handle 550MB’s writing on the SNV3400-400G.

Though we haven’t formally examined the Samsung 983 DCT, it seems to have a definite writing benefit over the IronWolf 510. However, the Seagate drive provides higher IOPS.

How this would possibly have a general effect on efficiency when the drive is used solely for caching and never direct file entry is debatable. However, we suspect that for these utilizing a NAS solely for file serving that the Samsung could be the higher alternative, the place these utilizing it for NAS put in functions would possibly discover the IronWolf 510 the cache of alternative.

NAS and SSDs

When a NAS field is stuffed with exhausting bodily drives, there are practical limits to how briskly it may possibly learn and write even with a superbly designed RAID configuration. Usually, a tough drive will learn and write at around 150MB/s, with a five drive RAID pack delivering around 400-450MB/s incomplete, or the equal of a single SATA related SSD.

Possibly a few years from now, 4TB SATA SSDs can be low-cost, and NAS containers can be awash with them, and the IronWolf 510 will make considerably extra sense then.

Alternatively, we’ll, in all probability, cease utilizing SATA and mount M.2 SSDs within the new super-tiny NAS containers and overlook caching storage operations totally.

Due to this considerably predictable future, the window of alternative for units just like the IronWolf 510 can be transient, and the following drive on this collection can be most certainly promoted as being for cache or storage.

Nonetheless, these future units will nonetheless want a construction just like the IronWolf 510 provides with inherent energy failure mitigation, making it extra doubtless that future designs would possibly incorporate this in all NVMe storage and never simply these particularly made for NAS use.


Synology has two NAS designed NVMe drives, the SNV3400-400G and SNV3500-400G that each is available in solely 400GB capacities and don’t evaluate the endurance or efficiency of the IronWolf 510 effectively. In addition, they make the Seagate drive look barely cheaper, with the SNV3400-400G sometimes costing $225 for 400GB, the place the IronWolf 510 is $169.99 for 480GB of capability.

The one different main model that has a NAS tuned NVMe drive is Samsung with its 983 DCT, constructed across the Samsung Phoenix controller. That is available in each 960GB and 1.92TB capacities, has the same DWPD, and prices $277 for the 960GB mannequin.

Ultimate verdict

Given the rock-bottom price of NAND at the moment, resulting from a below-predicted consumption and enhancing manufacturing yields, the worth of the IronWolf 510 is its greatest sticking level.

It’s rather more than a client NVMe drive, although it’s cheaper than the disturbingly costly Synology SNV3000.

Whereas we’re impressed with a number of the expertise that Seagate put within the 510, there are nonetheless many caveats to utilizing NVMe in NAS, not least these limitations placed on them by the NAS makers.

We’ve famous some, like Synology, don’t enable the NVMe storage for use for something aside from caching, and others enable it to be each.

Rising the cache by including a drive just like the IronWolf 510 will solely handle some efficiency issues, not all.

It’s good at enhancing efficiency points attributable to massive numbers of information in a single folder, quite a few, and often accessed small information. They’re additionally helpful for NAS-based functions that contain databases and the manipulation of enormous information units.

The place they don’t assist a lot is in a number of the very time-consuming workout routines {that a} NAS field can undertake, as a floor validation or rebuild. In addition, they received make file transfers to related host techniques run any faster because they restrict there’s community bandwidth.

The Seagate IronWolf 510 is a costly resolution from a noticeably shortlist of expensive NAS SSDs and one which must be deployed with some planning whether it is to be thought of worthwhile.
