SkyHawk Surveillance Hard Drive Reviewed

Regardless of how much storage you have, given enough time, you’ll generally require more. As a feature of my new form, I chose to pursue my standard technique of updating some portion of my storage to bigger, new drives for expanded speed, limit, and unwavering quality while pushing more established, littler drives out to cold-storage, for example, to spare vitality. Generally, the technique works out, yet as the drives get bigger, they normally get progressively costly per gigabyte. This implies the expense expands each time as capacity costs have apparently stagnated.

Previously, I had just looked into the Seagate Archive 12Tb series of drives in 2015, which ended up being a fascinating drive since it consolidated a substantial limit with ease. The tradeoff was conflicting I/O execution borne from the need to use SMR strategies to “pack” more information into a similar platter territory and block the need to utilize costly helium drive fabricating methods.

Quick forward to the last part of 2017, and confronting a similar difficulty of getting extensive mass storage at the most reduced conceivable value, I scoured the neighborhood PC looks for series. For reasons unknown, the Seagate Archive 12Tb drive was as yet accessible yet generally disagreeable at around AU$370 (a more expensive rate than when I got them in 2015). The other minimal effort choice was the Seagate Skyhawk Surveillance 12Tb drive, at around AU$360. Being AU$10 less expensive per unit, I couldn’t perceive any prompt drawbacks, thus I selected to acquire two units.

These are situated as a reconnaissance streamlined drive, with “ImagePerfect” firmware enhanced for the application, which apparently demonstrates organizing composes over peruses, guaranteeing similarity with DVRs/NVRs, possibly support for spilling compose/read directions and maybe a change to mistake taking care of conduct (as video can be to some degree tolerant to information misfortune with broken playback as a “glitch”, and quick drive recuperation would keep information misfortune from lined composes or the drive being considered “disconnected”). The drives offer multi-narrows support with rotational vibration sensors, a 3-year guarantee under all day, everyday control on-hour conditions and 180TB/year outstanding burden. Asserted most extreme non-recoverable read-mistakes per bits read sits at 1 in 10^15, which is a “run of the mill” figure, albeit a portion of their littler drives still cases 1 in 10^14. Also, this hard drive supports up to 64 HD cameras and limits dropped frames and decrease downtime.

Obviously, I wasn’t aiming to utilize them in observation applications. All things considered, I’m especially against fake market division through programming separation and I’m persuaded that under “general” remaining burdens (for example non RAID, low usage factor, at home), totally any drive should work fine and dandy. They are only a block storage gadget all things considered – store information in block X, read information from block Y.

Unboxing experience

Similarly, as with most fresher Seagate drives, they arrive in a static protecting pack which has seals along the long side of the drive. This is my first drive with their new “Gatekeeper” marking – for example Barracuda Pro, Firecuda, Ironwolf, Skyhawk. There is a crease at the back too. The bundling truly helps me to remember a chip parcel.

The drive is strong and profound in the hand, however, on the off chance that you’ve held the Seagate Archive series drive, you’d be confused with supposing they were the equivalent. The drive gauges an astounding 650g, and fundamentally makes utilization of practically all the space accessible to it, with a back packaging that is practically flush to the base screw gaps. The name on the best highlights their new logo yet, in addition, has QR codes for comfort in checking the drive’s data. The drive was Made in Thailand, with model number ST8000VX0022 and firmware update of AV01.

Indistinguishable to the Seagate Archive, it passes up the middle screw gaps on the two sides. In the event that your case requires them, at that point this drive probably won’t be the one for you.

At the back, we have the standard SATA and power connector positions alongside a troubleshoot port. At the front, we have a sequential number mark for speedy recognizable proof and a ventured locale of the case which may be utilized amid computerized assembling.

What did we notice after teardown?

As the ever-inquisitive kind of individual that I am, I have chosen to mostly dismantle the drive (non-ruinously) to perceive what was on the PCB.

Much the same as the Archive, the PCB has this L-shape with two warm cushions exchanging heat from the controller and engine driver. A froth protection sheet with translucent plastic covers the board to counteract shorting to the case – there is where a vast cluster of MLCC capacitors is situated close to the power taking care of a segment of the board.

Expelling these enhancements uncovers the principle board which is essentially indistinguishable to that of the Archive drive with the special case that an EEPROM has been supplanted with a surface mount gadget. Three vibration sensors can be seen (two substantial, one little at symmetrical pivot). Besides the principle, the controller is a bit of Samsung DRAM for the reserve.

With an expansion of a smear of warm oil, the codes for the chips can be unmistakably settled. For reasons unknown, they’re actually equivalent to on the Seagate Archive drive which is an SMR 5900rpm drive. Or maybe fascinating to see the extensive dimension of similitudes between the items – including the cost.


Testing was performed on my new workstation throughout the capacity appointing tests. As the two units tried showed fundamentally the same as execution, the outcomes for only one unit will be displayed.

Directly off the bat, the drive posts a great external measurement successive read rate of 227.4MB/s, averaging 185.2MB/s. The bend is fairly smooth, recommending some refined account plot which keeps all tracks at the equivalent areal thickness (instead of the ventured multi-zone recording of old, or the “wavy” versatile thickness plans). The drive shows three obvious plunge zones, which recommends these zones might be saved for slipping/reallocations or drive working firmware.

Successive compose execution was much the equivalent, with a similar trademark shape, despite the fact that the entrance time was somewhat dispersed recommending some firmware-streamlining conduct (for example detailing composes cleared before they really occur). In any case, that is not really anything new as most drives do this somewhat in any case. Be that as it may, the extent of higher-get to times appears somewhat strange.

This conduct reached out to irregular access tests. While hard drives don’t break any IOPS records, it appears to be certain that the compose IOPS are higher than perusing IOPS. No enormous astonishment the same number of drives is streamlined along these lines. The huge shock was irregular composes where the most extreme access time spiked to 2.5 seconds – this doesn’t appear to be especially befitting for a reconnaissance drive, yet on the other hand, maybe observation recording is successive essentially.

Additional tests were performed, in spite of the fact that they’re not especially important when all is said in done. No record benchmarks were finished with HD Tune Pro, sadly, be that as it may, we do have CDM and ATTO to go on.

Out of the blue, a full arbitrary fill and confirm was performed on the drive to check its working. At last, the full round excursion took barely short of 24 hours – obviously from a mammoth drive.

CDM reports execution somewhat higher than desires dependent on the HDTune Pro outcomes. The outcomes are especially useful for a hard drive, particularly when contrasted with more established drives. Nonetheless, obviously, little block gets to are greatly improved dealt with by strong state storage.

ATTO appears to demonstrate the drive achieving full I/O execution by 8KB and keeping up a moderately steady series of results. This shows great I/O execution conduct.

It was so out of the blue great that I re-ran the test a couple of times incorporating with no covering I/O and with a bigger exchange length. The execution stayed comparative, with full rates at 32kB, so it was not prone to be a consequence of storing.

In any event, it wasn’t the extremely conflicting outcomes similarly as with the SMR Archive drive. It appears this drive likely could be PMR.

A full test was performed with H2testW and no information trustworthiness mistakes were accounted for. Note that the mistake on the left is typical as H2testW ascertains the rest of the space toward the start and this isn’t really accessible due to filesystem development amid testing as documents are being made.

After broad testing, the drive stayed sound, be that as it may, the Hardware ECC Recovered quality 0xC3 was a strangely low figure (talked about in the following segment). The drive kept up a 44 degree temperature under burden while being cooled before a fan, so it’s a significant warm drive with a guaranteed 9W normal working force and 8W lingering normal (which is higher than green drives of the past, or even the chronicle which has a normal working of 7.5W and inactive normal of 5W). That is normal from the higher shaft speed. An opportunity to prepared is likewise around 30 seconds, and it’s recognizably moderate to get up to speed when originally fueled up or awoken from rest. For the individuals who don’t rest their drives, that is no major ordeal.

Few tips

While the drive is by all accounts all that I had wanted, particularly at the value point, all may not be very impeccable. Based on the SMART information, the low an incentive for Hardware ECC Recovered recommends that there might be a punishment from going to PMR at such high densities.

In most of the Seagate drives I’ve possessed, the incentive for this figure sits at around 30 to 55 for most standard drives and around 100 to 120 for my Archive drives. The main special case was a couple of Seagate ST2000DL003 which had qualities around 5 to 6, one of which bombed inside around three years, growing moderate I/O and 3975 reallocated areas.

I presume the SMART esteem signifies the relative edge between the read-flag and the purpose of disappointment where blunder revision can’t reestablish the recorded information. I presume low qualities demonstrate that the recuperated flag is nearer to the edge of unrecoverability, in spite of the fact that this is just theory.

As the SMART information isn’t institutionalized among producers and models, and makers are not proactive about educating shoppers about precisely what the measurements mean, this is only my doubt. In any case, it makes sense thinking about that only two years prior, SMR was totally important to accomplish such densities in non-helium drives while meeting purchaser desires and that from that point forward, no significant leaps forward in PMR innovation have eventuated.

As a traditionalist individual with regards to new capacity innovations, I survived the LMR to PMR progress period. At the point when LMR was achieving its mechanical limits, the biggest drives achieved 500Gb utilizing five platter game plans. Most of the standard client drives had up to three platters, so we saw limits around 320Gb toward a mind-blowing finish. At the time, more current 500Gb, 600Gb and 750Gb drives with PMR were being discharged yet as I was suspicious of the dependability of the drives, I conveyed various 320Gb drives in a NAS.

This unexpectedly turned out to be a terrible decision, as the 320Gb drives worked so near their edges that powerless parts created more than two of the eight drives I had, bringing about sporadic information misfortune that (when changed) did not result in reallocations, bringing about additional information misfortune later on. The new drives utilizing PMR that my companions grasped, strikingly enough, had no serious issues and neither did my more seasoned 200 and 250Gb drives dependent on a less-thick platter plan.

I surmise a similar situation may play out once more. As a doubter of the long haul unwavering quality of helium based drives (and perceiving that helium should be moderated), I have opposed the move to helium. Another reason is cost. However, as we push PMR as far as possible, Seagate appeared to settle on a shrewd choice to back-off on the thickness and move to SMR in the Archive series. Yet, it appears that the market has not especially taken to SMR drives with a similar excitement (regardless of whether they are unintentionally given them in outside drives). Might Seagate be forsaking SMR for pushing PMR considerably further – maybe excessively far? I surmise the truth will surface eventually.


While the Seagate Skyhawk Surveillance drive imparts likenesses to the more seasoned Seagate Archive drive as far as a large portion of its parts, the execution of the two drives is very unique. The Skyhawk’s quicker 7200rpm shaft speed gives much enhanced successive execution, and its design appears to look like a conventional PMR drive with no of the SMR-instigated throughput varieties and moderate downs experienced, all things considered. The Skyhawk is additionally less expensive, making the Archive drive for all intents and purposes insignificant for general customers. This drive can offer such a limit without turning to helium-based innovation, which keeps the cost reasonable.

On account of the similitudes, the drive (likely) has a similar 6-platter, a 12-head game plan which may turn out to be an unwavering quality issue. As a result of the turning mass, it additionally takes around 30 seconds to come up from an axle ceased condition. That being stated, my four Archive drives have timed 18,000 hours each with nil disappointments, in any case, your mileage may differ. It’s likewise genuinely substantial and runs generally warm (testing was led with a fan specifically before the drive sound). It passes up a major opportunity the middle mounting opening on the two sides which may affect similarity with a few cases.

Generally, the drive is by all accounts a decent decision all in all – it’s extensive, it’s quick, it’s steady, and it’s moderately modest. Be that as it may, regardless of whether it ends up being solid over the long haul must be evaluated through the progression of time.
