Cool Spin design for desktop computers. The Desk star 5K3000 hard drive provides an enormous 2TB capacity and features innovative Cool Spin technology to deliver a greater level of power efficiency and quiet operation for energy-conscious, computers. Key to Cool Spin technology is an optimization of motor speed to provide an ideal balance of performance, power utilization and acoustics. The Cool Spin technology, along with other Hitachi power management techniques, gives the Desk star 5K3000 its 29% power savings over the Desk star 7K3000. This new 2TB is the first Hitachi Cool Spin hard drive with a 6Gb/s SATA interface. With low power, high capacity and cool operation, the 3.5-inch Desk star 5K3000 allows manufacturers to leverage the benefits of the latest components and operating systems to deliver more systems. Manufacturers planning to use the highest capacity 2TB drive in systems should consult the Hitachi High Capacity Technology Brief. Power efficient for cooler operation

Great HDD for home NAS and great price for 2TB HDD,
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 all.
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.
Update 2012/04/28: Everything is still working very good. Ubuntu Server has been upgraded to 12.04.

|Surprisingly fast Green drive,
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 quiet drives to complement growing media storage needs,
When Amazon ran a promotional pricing on these Hitachi hard drives, I leapt on the chance to upgrade my existing 1TB drives and make space for future storage requirements.
The drives arrived packed fairly well, but the creative cardboard suspension of the box design did not leave a lot of open air space around the drive. It would have been preferred to see some additional packing or buffer material to better protect them during shipping. I understand that the drives are sold as OEM and that there is a growing initiative to conserve on consumed materials, but these are very sensitive devices.
Upon unpacking and installing the drives, I ran a full disk format and surface test on each of them. The first two had no issues and SMART reported no trouble areas. The third drive, however, produced a scattered set of unreadable/bad sectors and SMART reported surface errors and slow to read/unreadable areas. The drive was usable, as bad sectors can be and are often remapped to remain unused, but I opted to exercise Amazon’s great return system and had a replacement drive sent to me. The replacement drive tested just fine, and they are spinning away in my system.
I’ve owned enough hard drives over the years to understand that there are failure peaks at installation time, and can characterize the compromised drive as an early/factory defective. I have no doubts as to the reliability the drives once put into field service and when they have passed the initial surface verify/SMART tests. I feel that this is a good practice for any system builder or end user – a few hours of testing can prevent weeks or months of headaches as you try to track down what ultimately stems from a first-use defect.
As to the drives themselves, they run extremely cool; they remain room temperature even after continuous use, in stark contrast to many 7200RPM models. They are also extremely quiet in operation, barely audible by themselves, and certainly nothing that will noticeably raise the noise level of a typical computer enclosure. This would be a good drive for a MicroATX or Home Theater PC build, where cramped conditions can cause temperatures to soar. It would also work well in an external drive enclosure that does not utilize a fan for cooling, as little heat will need to be dissipated through the case. Transfer rates are very respectable, averaging at about 100MB/s across the disk surface for read speeds. Great for media storage, or for a NAS or other networked storage array or backup solution.
I’m very happy with the drives – they were a great value and are perfect for my application. Spacious, cool, quiet and an excellent complement to a solid state boot drive. I did get a drive that showed signs of failure right out of the gate, but I won’t fault the other drives for what is very likely a statistical outlier.
Recommended!
