ServersStorage SystemsHGST ULTRASTAR HE12 vs Seagate Exos Hard Disk Spec Comparison May 11, 20187468 views0Share By IG ShareSeagate and Western Digital are two of the most successful computer storage providers. They manufacture various types of storage solutions including mainstream hard disks, SSDs, network storage, storage for CCTV / Security system, etc. Today, we will be talking about conventional enterprise level hard drives, and figure out which of them provides the best solution (HGST ULTRASTAR HE12 vs Seagate Exos).Note: If you buy something from our links, we might earn a commission. See our disclosure statement.For this comparison, we have selected the following products from both Seagate and western digital:HGST Ultrastar HE12Seagate EXOS X12Table of Contents ToggleHGST ULTRASTAR HE12 vs Seagate ExosGeneralMiscellaneousInterface ProvideHard DriveEnvironmental ParametersDimensions & WeightPower ConsumptionService & Support DetailsShock & Vibration ToleranceConclusion:HGST ULTRASTAR HE12 vs Seagate ExosWe will go through every small technical detail and specifications, which will help us understand what and how something makes one better from the other. Note that both of these products are enterprise level storage solutions and we have opted the same storage capacity models so that the comparison would be fair and square.So without any more delay, here is our comparison:GeneralSpecificationHGST Ultra-Star HE12Seagate EXOS X12Device TypeHard drive – internalHard drive – internalBytes per Sector512512InterfaceSATA 6Gb/sSATA 6Gb/sBuffer Size256 MB256 MBWeight23.28 oz22.93 ozManufacturerWestern Digital Corp.Seagate TechnologyLet’s begin with a general introduction to both products. As you may already know, EXOX X12 is manufactured by Seagate storage solutions while HGST Ultrastar HE12 is a western digital product. Both models used in this comparison deliver 12 GB of storage capacity and thus having the same amount of buffer size, which is 256 MB.The buffer cache merely is embedded memory on a standard hard disk drive which helps it to buffer data between the storage drive and rest of the computer system. The buffer cache, the faster a hard disk drive will perform. 256 MB is the maximum buffer cache for modern hard disk drives; you cannot get better than that. Here, you should note SSDs hold up to 1 GB of the buffer, that’s why they perform comparatively faster.Both Ultrastar HE12 and EXOS X12 feature SATA interface, with up to 6 GB/s transfer rate support. You might have noticed that Seagate is a bit lighter than HGST. However, it matters the least or not at all.MiscellaneousSpecificationHGST Ultra-Star HE12Seagate EXOS X12MTBF2500000 sec2500000 secMTBF stands for Mean Time Between Failure. This unit is used to scale the reliability and durability of a storage device. It indicates the average time between ones internal failure/error and the next one during the device’s lifespan. Here, you can see that both storage drives have the same MTBF. However, these numbers are unreliable and unrealistic sometimes.Interface ProvideSpecificationHGST Ultra-Star HE12Seagate EXOS X12Qty11Storage InterfaceSerial ATA-600Serial ATA-600Hard DriveSpecificationHGST Ultra-Star HE12Seagate EXOS X12Form Factor3.5″3.5″Spindle Speed7200 rpm7200 rpmFeatures:24×7 availability, Enterprise, Instant Secure Erase (ISE), Perpendicular Magnetic Recording (PMR)24×7 availability, Advanced Write Caching, Seagate Secure, Super Parity, Superior Wide-Weld Hermetically Sealed-Drive enclosure, advanced format 512e, pressure sensor, Helium technology, Hot-Plug Support, Low Halogen, Multi-Step Forged Helium Sealed-Drive design, Organic Solderability Preservative, Power Balance technology, PowerChoice, Seagate RAID RebuildHard Drive Typeinternal hard driveinternal hard driveForm Factor (Short)3.5″3.5″Form Factor (metric)8.9 cm8.9 cmForm Factor (Short) (metric)8.9 cm8.9 cmStorage InterfaceSerial ATA-600Serial ATA-600InterfaceSerial ATA-600Serial ATA-600Average Seek Time8 ms4.16 msData Transfer Rate600 MBps600 MBpsBuffer Size256 MB256 MBBytes per Sector512 Hz512 HzNon-Recoverable Errors1 per 10^151 per 10^15Both HGST Ultrastar HE12 and Seagate EXOS X12 support standard 3.5″ bays and deliver spindle speed of 7200 RPM. Both provide the same data transfer rate of 600 MB/s (Theoretical Peak Interface Speeds).Moreover, their bytes per sector, buffer size, and nonrecoverable error values are the same as well. The non-recoverable error indicates the occurrence of an error which cannot be recovered later on. The only difference here is of average seek time. HGST has a seek time of 8 milliseconds, for Seagate, it is only 4.16 milliseconds. This difference seems tiny but makes a significant impact on real-time performance. The less seek time; the faster data will be loaded into main system memory.If you put it in figures, Seagate delivers almost double speed in seek time, compare to HGST, so its clear winner here. Moreover, it throws many additional security and performance features while HGST offers a few only.Environmental ParametersSpecificationHGST Ultra-Star HE12Seagate EXOS X12Min Operating Temperature41 °F41 °FMax Operating Temperature140 °F140 °FThere is zero difference in minimum and maximum operating temperature range for both HGST Ultrastar HE12 and Seagate EXOX X12.Dimensions & WeightSpecificationHGST Ultra-Star HE12Seagate EXOS X12Width4 in4 inDepth5.8 in5.8 inHeight1 in1 inWeight23.28 oz22.93 ozAs both HGST Ultrastar HE12 and Seagate EXOS X12 possess same form factor, their dimensional elements are the same. However, there is a slight difference in weight, which is the novice. We are pretty sure it won’t affect the build at all.Power ConsumptionSpecificationHGST Ultra-Star HE12Seagate EXOS X12Modeactive, idleactive, idleValue5.3 Watt, 7.2 Watt5 Watt, 7.8 WattBoth the models have two states only, active and idle. It is quite surprising they are not offering sleep mode. Without it, the device will stay in the idle situation rather than turning itself off while your system is hibernating. In the active state, HGST Ultrastar HE12 consumes 0.3 Watts more than Seagate EXOS X12.However, in the idle state, Seagate EXOS X12 consumes 0.6 Watts more compared to HGST Ultrastar HE12. HGST consumes a bit less power compared to Seagate. However, it is quite considerable since Seagate is offering more features and reduces the average seek time.Service & Support DetailsSpecificationHGST Ultra-Star HE12Seagate EXOS X12Typelimited warrantylimited warrantyFull Contract Period5 years5 yearsShock & Vibration ToleranceSpecificationHGST Ultra-Star HE12Seagate EXOS X12Shock Acceleration (Operating)70 g–Shock Duration (Operating)2 ms half sine wave–Shock Acceleration (Non-operating)300 g–Shock Duration (Non-operating)2 ms half sine wave–Vibration Acceleration (Operating)0.67 g–Vibration Frequency Range (Operating)5-500 Hz–Vibration Acceleration (Non-operating)1.04 g2.27 gVibration Frequency Range (Non-operating)2-200 Hz10-500 HzAs described above, both manufacturer’s are offering five years of limited warranty on these products, which is tremendous and assuring. For more details on their warranty policies, you can visit the links below or refer to the manufacturer’s website and search for the particular product.As the table above indicates, HGST offers much more features when it comes to shock and vibration tolerance. Here, it knocks out the Seagate completely. When building a full-fledged rig, there are high chances of vibrations and shocks on peak moments. These factors would surely make a difference in such conditions.Buy These Here:[amazon_link asins=’B0759Q9FXZ,B079SJCCWZ’ template=’ProductCarousel’ store=’foi04-20′ marketplace=’US’ link_id=’fe992e9c-554b-11e8-ab3e-c17d405c774d’]Conclusion:In the end, all we can say is that Seagate is better when it comes to faster data access and security features. However, HGST offers more durability and sturdiness.It is up to you what you require more.
