    The Hitachi 5K3000 is a very solid 2 TB Green drive that seems to run 20-25% faster than fellow Green alternatives. 5 stars.

    The bottom line for performance is that spindle speed that runs at 5940 rpm, or 500-700 rpm faster than alternatives, seems to noticeably boost performance. Sequential read/write is in a very impressive 140ish MB/s range versus 90-95 MB/s or so for my previous generation WD EACS and EADS models. It’s definitely still not a 7200 rpm drive though; real read access times seem to come out in the 19 ms range, or on par to slower than other Green drives, and the 32 MB cache versus 64 MB for competitors does limit burst speed a bit. No one will ever mistake this for an SSD or 15k rpm SCSI, but in a pinch this might be fast enough to do a decent job masquerading as a primary desktop drive.

    These are also very quiet drives. Currently they’re in a Tivo Premiere and a 4-in-3 RAID 5 array, and neither setup produces any audible drive noise over the fans used to cool their respective enclosures. My own very informal testing showed fairly decent power consumption; with a Kill-a-watt hooked up to the rig, the overall draw seemed to be around a 5-6 watt range per drive while undergoing extended SMART tests, or essentially similar to other competitors marketed as Green. These also do seem to run cooler in the drive enclosure than my previous drives based on a simple radiant heat touch test.

    Reliability at this early stage is always a crapshoot, but a 3 year warranty should help. Recommended.

    Great HDD for home NAS and great price for 2TB HDD, February 26, 2011

    I bought four of these HDDs for my home made NAS and they are working great and fast enough.
    They have really impressive performance for green HDD. Comparable to WD Green drives, these are the best.
    I host lots of services on my NAS for many users(~20). No lags, no problems, everything works great.

    Don’t worry that they are SATA III, but you have SATA II interface, on these and almost all non-SSD drives you’ll not gain extra performance at alll.
    To get at least 3-5% of extra speed on SATA III, you HDD drive should be able to read/write at least 220-230MB/s.

    hdparm test:
    root@nasik:~# hdparm -t /dev/sda

    /dev/sda:
    Timing buffered disk reads: 402 MB in 3.00 seconds = 133.82 MB/sec
    root@nasik:~# hdparm -t /dev/sdb

    /dev/sdb:
    Timing buffered disk reads: 390 MB in 3.01 seconds = 129.47 MB/sec
    root@nasik:~# hdparm -t /dev/sdc

    /dev/sdc:
    Timing buffered disk reads: 378 MB in 3.00 seconds = 125.88 MB/sec
    root@nasik:~# hdparm -t /dev/sdd

    /dev/sdd:
    Timing buffered disk reads: 394 MB in 3.01 seconds = 130.98 MB/sec

    NAS config:
    1. 8GB USB flash – OS installed.
    2. 2 x 2GB Dual Channel DDR3 Memory
    3. 4 x 5K3000 Hitachi 2TB HDD
    4. CPU: Intel Core i3 Processor i3-530 2.93GHz 4MB LGA1156
    5. motherboard: Intel Media Series Mini-ITX Motherboard Supporting Intel Rapid Storage Technology (RAID) BOXDH57JG
    6. Case: SERVER CHA CHENBRO ES34169-BK-120R. To reduce noise, fan voltage is changed from 12V to 5V.
    7. Extra fan for case Vantec Stealth SF6025L 60x60x25mm Double Ball Bearing Silent Case Fan (Black)”
    8. CASE needs low profile fan for CPU – Thermaltake Slim X3 Low Profile 36mm Height CPU Cooler CLP0534
    9. OS: Ubuntu Linux 10.10
    It is $400 hardware set + $current price * 4=… for 4 HDDs, much cheaper than baying Atom/ARM based NASes which are expensive and very slow.
