Seagate Delivers "Next-Gen" HDD

By - Source: Tom's Hardware US | B 19 comments

Seagate is boasting that its SV35.5 Series is the next step in the HDD evolution, geared to deliver optimal performance in digital video surveillance systems.

Seagate is boasting that its SV35.5 Series is the next step in the HDD evolution, geared to deliver optimal performance in digital video surveillance systems.

But what really speaks out is Seagate's claim that the SV35.5 Series hard drive was built for rigorous 24x7 use. Honestly, that should be the case for any hard drive, especially when considering that most consumers today juggle large files on a daily basis. However, the SV35.5 hard drive doesn't seem to be geared to the every day consumer, but rather end-users who need a drive that can handle huge processing loads stemming from digital video surveillance systems.

“The hardware requirements for the surveillance market are especially critical and dictate the use of HDDs that are made specifically for the needs of video system manufacturers and integrators,” said Carla Kennedy, senior vice president of Seagate’s Enterprise Product Line Management group. “With its optimized performance and capacity that can store over one full month of high-resolution video, the Seagate SV35.5 Series hard drive is a prime example of Seagate delivering a feature-rich solution that customers have requested.”

Seagate's SV35.5 series comes in three varieties to fit every video need: 250 GB, 500 GB, and 1 TB. According to the company, all three models use perpendicular recording technology to offer >1 million hours MTBF and <1 percent AFR in 24x7 video surveillance applications. Additionally, the series boasts many other impressive features including spin speeds of 7200-RPM, 47 simultaneous FULL D1 (704x576) video streams support, ATA-7 streaming commands (that optimizes video streaming performance and integrity), and 140 MB/s sustained sequential data rates. The series even takes full advantage of a 3 Gbps SATA interface.

But while sitting idle, the SV35.5 series uses only a meager 5 watts for the 250 GB version, 7 watts for the other two models. The 250 GB version also takes advantage of 8 MB of cache SATA, while the 500 GB and 1 TB offers 16 MB and 32 MB respectively. Moreover, the Seagate SV35.5 series is rather quiet: the 250 MB version is a whispering 2.3 bels, and 2.5 bels for the other two models, offering "best-in-class acoustics for extremely quiet operation" as Seagate states.

Finally, all three drives offer enhanced caching capabilities, built-in error recovery for non-stop streaming, thermal monitoring and reporting, unique user-selectable partitioning, and low spin-up power. The series' 20-mm form factor also provides more ventilation in a multi-drive environment, and is capable of operating under drive case temperatures of up to 70°C. The SV35.5's low power consumption should keep the heat generation to a minimal.

Seagate said that its SV35.5 series is best suited in applications serving as video surveillance digital video recorders (SDVR), video surveillance network digital video recorders (SNVR), and direct-attached and network-attached JBOD video surveillance storage.  Still, the SV35.5 series would be ideal for home consumers editing tons of video on a daily basis, or gamers wanting to build the ultimate rig.

    Maybe it's just me, but I'm hoping that Tom's Hardware does an in-depth review of this new product. I am really looking forward to seeing how this drive does in a 'high end gaming rig'...or how it stacks up to the 7200.12 drive and other higher end mechanical disk drives, even SSD's... Speaking of which, why hasn't Tom's Hardware done a review on the Seagate 7200.12 HDD's yet?

    lol since when was 7200rpm an impressive feature, just because other companies are going backwards doesn't make this impressive.

    Who uses bels for sound level anymore? 23 decibels and 25 decibels would be much more appropriate. I guess marketing won out on that one.

    In any case, I'm sure this is a market that needs to be addressed. Although I was sucked in by the headline, I really don't care much about the content. No revolutionary HDD tech going on here except for video surveillance technology.

    Seems to me that Blue-Ray's flop in the tech industry and SSD's Shakespeare worthy 'delay' (think Falstaff) in development of capacity and price reductions is breathing new life into what was a dying (weakening at the very least) hard drive industry. Seagate may have a reason to charge $175+ for a 1Tb hard drive again.. tee-hee (current street price is about $90).

    How will they resolve the "heat assist" perpendicular hard drive technology with 24/7/365 capability.. last recent memory puts 2+tb capacity drives at odds with ultra large MTBF, low heat, high thermal tolerance and low acoustical output-- but I digress.

    I'm still waiting (with bated breath) for a 750gb 7200rpm 2.5" laptop hard drive to materialize with similar characteristics.

    I will take my Fujitsu UWSCSI 15,000RPM Drives over these Seagates.

    1TB HDD has been around since 2007 when are 2TB discs coming?
    Also after the Seagate bug that bricked the disc, most of my new purchases have been WD, hard to trust them again I guess...

    ^^^^^

    2 TB HDD's are here!!!! So are 1.5 TB HDD

    ^^^
    Is the 1.5 TB

    My Maximum PC MAG says Western Digital has the 2 TB out!!

    TheFaceWho uses bels for sound level anymore?

    The same people that use bits instead of byte to measure bandwidth.

    I have flash drives with larger capacity, no moving parts, and no audible sound. Might wanna correct that.

    Why do smaller drives have smaller cache? Cache is used to speed-up reads and writes. It's not like a smaller drive will be used less often than a larger one, especially not for streaming video applications.

    I'm sure I've seen a review here that covers cache size (I think 16MB was sufficient), but really, for a drive geared at storing streaming video, capacity is only how much history is stored, not how much the drive is accessed. Doesn't seem logical to use different cache sizes.

    I often wondered this myself... Why not have 32mb cache in all the drives?

    It takes longer to traverse a larger cache, so if you buy a smaller drive the partial assumption is you will be doing smaller file transfers in which a smaller cache is faster for cache hits. It also has to do with price point, smaller capacity, smaller profit, so using less ram helps keep the revenue higher.

    Also note that currently ALL had drive manufactures are having issues with 2TB. The current best head/media combo (something like TDK/fujitsu)with a marvel channel is having difficulty in signal to noise ratios at 2TB densities. The yield for 4 platter 8 head drives is very low, making it not feasible to ship. Two head 1 disc on the other hand has much higher yields and that's why the 7200.12 is a one disc 2 head drive that is shipping, but a 4 disc model of the same density is not shipping. Until there is a break through in head/media/channel technology we will most likely not see large volumes on 2TB drives. The other options are, slower spin speed with higher over sample (WD uses this currently among other things) or moving to a larger sector size than 512 bytes to increase format efficiency.

    What's with the double into, can't they edit these articles properly.

    I fail to see the point in this piece of news?
    Other than 140MB/sec I don't see anything nextgen about it. Looks to be an old maxtor drive (maxtor discount drive form factor anyway) with a specialized firmware. Also the stats are pretty .... stock. Most WD drives have AFR of under 0.8% so that can't be it. All manufacturers provide drives with that spindle speed, and many provide low power variants. I bet if WD would provide a similar specialized firmware for their wd20eads it'd beat this drive in all specs. Essentially the only thing these 3 seagate models provide is a firmware with different error handling and different storage algorithms....
    And how important is it anyway? I've only seen one harddrive in a surveillance system break, and it was a regular old 5400rpm ide drive many years ago. The systems we have now, according to my knowledge, run on ordinary 24/7 drives and seem to cope just fine.
