Hitachi: Deskstar 7K1000 and Deskstar 7K1000.B

Tom’s Winter 2008 Hard Drive Guide
By

There are currently three Hitachi mainstream hard drive families on the market: the Deskstar 7K1000, the 7K1000.B and the E7K1000. The first one is the first generation terabyte drive, the .B drive is the second generation, and the E7K1000 is the new low-power drive that is based on the second generation. We have not yet received the E7K1000, but looked at the other two.

Deskstar 7K1000: First Generation Terabyte Oldie

Hitachi’s first-generation Deskstar 7K1000 was released in spring 2007, and the firm deserves kudos for having released the first hard drive that provided a total capacity of one terabyte. The drive reached its capacity using five storage platters, and had a 7,200 RPM spindle speed, a Serial ATA/300 interface and 32 MB of cache memory—this was also the first time this cache capacity was deployed.

However, the Deskstar 7K1000 can no longer be considered a modern hard drive—there are faster and more efficient drives around, including the 7K1000.B. If you intend to go for a Hitachi drive, be sure you don’t get the HDS721010KLA330 Deskstar 7K1000, as it gets hotter and delivers less performance than its successor.

Deskstar 7K1000.B: B Like Better

The Deskstar 7K1000.B is Hitachi’s latest terabyte hard drive. While other hard drive makers such as Seagate decided to jump to the next capacity point of 1.5 TB right away, Hitachi preferred to create a new terabyte drive. The 7K1000.B at 1 TB capacity is called HDT721010SLA360, and is based on three platters instead of five. It still utilizes Serial ATA/300 and the same 7,200 RPM spindle speed, but the cache capacity was reduced from 32 MB to 16 MB, which didn’t hurt performance at all. To the contrary, the Deskstar 7K1000.B is one of the fastest and most balanced hard drives available today. It pairs great performance with power efficiency.

While the old Deskstar 7K1000 was available only at 750 GB or 1000 GB, the new 7K1000.B is available at all capacity points. You can choose among 160, 250, 320, 500, 640, 750 and 1,000 GB models. Typically, the 640 GB or 750 GB models offer the best cost per gigabyte ratio. Please consider that the higher capacity versions require more power due to the larger number of platters and that performance varies from one capacity point to the other, depending on how much of the total recording area of each platter is actually being used.

    I would be interested in seeing how SSDs have effected Raptor sales.

    I honestly think SSDs wont touch Velociraptor sales. The price tag is just too different. Even 300Gb is kinda short. Not to mention 64Gb.

    SSDs for now are only rich lappy owners. For the rest, there is SAS.

    There are 30gb OCZ SSDs on newegg for $80 each. Anyone wanting a faster drive for the OS would definitely consider the SSD over a Raptor.

    Have you seen the OCZ horror stories?

    SSD doesn't equate to better performances than raptors. Watch out for that :) 

    thanks for the review, it's nice to see the Hitachi's getting updated to such fast drives.

    EcoGreen F1 @ -60C operational temperature? That may not be the most ideal enviroment to run a pc ? might want to add a zero in front :) 

    ps. no noise measurements?

    yes, no noise measuring? That is a important as anything else for a HTPC?

    SSD's aSSD's, especially the MLC ones, are not effecting gaming machine sales (raptor). They're terrible for PC's right now that run Windows. They're better than their initial release. But they're still not something to overtake the markget for a while.

    The gallery thing is so user unfriendly. I hate it so much since its introduction. It takes much longer to load, and I have to switch between browser windows constantly to see all the images. Please go back to the old design and show all the images in a few pages directly. I don't want to keep switching!!!

    I am using two 1.5TB drive in RAID 0 under Vista x64 and it doesn't feel any faster than the two 320GB 7200.10 RAID 0 drives it replaced. The throughput for the 320GB is 70 MB/s or 140 MB/s on RAID 0; the 1.5TB should be noticeably faster but it isn’t.

    BTW, the maxima drive size windows can address is 2TB so my 2*1.5TB shows up as one 2TB + one 700GB drives.

    This is one of those articles that reminds me why I like Tom's so much: quantitative comparisons that are useful.

    Properly-designed flash-based solid state drives are not only faster than conventional drives, they can also require considerably less power


    LMAO! A couple of months ago Tom's had an article saying that the energy-saving of SSDs was a hoax. The title even had the word "hoax" in it. I called their bluff, and got down-rated in the comments on that article. Now, they're saying the exact opposite! How many times does Tom's say one thing to spark controversy and get website hits, and then say the exact opposite later on? This website is SO FULL OF CRAP.

    SSDs ARE faster than HDDs, IF you have the right SSD. Furthermore, that is not the ONLY advantage to having an SSD. Heat, energy use, ability to handle more shock, and noise all contribute.

    XP and Vista is not correctly optimized for SSDs, but that doesn't mean that a high end SSD won't outperform hard drives on them.

    DFGumExcept there not faster.

    Yeah those cheapo OCZ (etc) drives are incredibly slow. My next harddrive will be a 500GB Seagate 7200.11. That should last me at least 2 years, and then I'll go with maybe a 512GB SSD or something. Surely they'll have 512GB SSD's that provide at least 200MB/s read and 150MB/s write at a reasonable price in 2 years.... especially with all these memory prices dropping. Last year you could get 2x2GB of DDR2-800 for ~$200. Now, 2x2GB of DDR2-800 can be had for under $50, and even lower then that after rebates!

    The WD Raptor 36GB and above can still be used within a raid-0 array. Heck thats what i'm using now, i was looking for SSD's but too much SSD's that have their issues and wont come down at least for 350€ for a decent Raid-0 set.

    I checked Newegg and noticed that the following drives aren't readily available, yet Tom's is recommending them. What's up ?

    Hitachi 7K1000.B
    Seagate new 1TB

    I look at not only the length of the warranty but the quality of the support. When my seagate failed I had to pay a total of $27 for advanced replacement. When my western digital failed advanced replacement was free and I only paid $7 for a optional prepaid return shipping label.

    Also I had to get to page idk 17 or 19 in the RMA process before I saw anything about an advance replacement fee.

    I am not saying I won't ever buy a seagate, just saying I lean heavily toward WD because of the way they handle replacements.

    I wish I new all the manufacturers policies on advance replacement fee's. But one's that charge don't advertise it so I am kinda in the dark.
