Summary: Despite being an older model without the latest advances in areal density, the Hitachi Deskstar 7K3000 2TB hard drive still managed to tie the Seagate Barracuda 3TB for the top 7200 RPM spot in our real world benchmark suite, making it excellent choice for a high capacity, operating system drive (the Barracuda is faster over its entire span though). Its airborne acoustics are middling, but acceptable given the drive's speed.
Summary: In both our Premiere Pro encoding test, which writes a 20GB uncompressed AVI to the disk, and the PCMark Vantage HDD subtest, the Deskstar performed faster than the Barracuda XT, despite having largely the same specs and despite the Barracuda’s faster average read and write speeds. The Deskstar’s random-access speeds were fully 2ms faster than the Barracuda’s.
Pros: Fast, capacious, and relatively inexpensive; helpful software wizard.
Cons: Sequential reads and writes lag very slightly behind Seagate’s offering.
Summary: On one hand, the Deskstar 7K3000 represents an impressive milestone for mechanical storage. On the other, it's the latest example of Hitachi reaching a new capacity with five platters instead of four. Adding another platter to compensate for a lower areal density is hardly cheating, and it may even pay dividends if there's truth to Hitachi's claim that lower areal densities lead to fewer media and head failures over the long term.
Excerpt: The Hitachi Deskstar 7K3000 internal hard disk drive is an entry into the rarefied space of drives that offer three-terabyte (3TB) storage capacity. Other brands in this space include Seagate and Western Digital.
Excerpt: The Deskstar 7K3000 is the first 7,200rpm hard disk we've seen with a massive 3TB capacity. However, there are several technical issues which make it less than ideal for mass deployment as Tom Morgan explains.
TechEye looks at Hitachi's Deskstar 7K3000 3TB drive
4 February 2011
Conclusion: Huge capacity matched with stunning performance thanks to its fast spindle speed and interface, the only fly in the ointment is the hardware needs as a boot drive and the need for a modern OS but that's hardly the drive's fault. The price tag is on the expensive side, but then this is a drive aimed at the performance end of the market.
Pros: Stunning performance
Cons: Needs the latest motherboard BIOS technology as a boot drive Price
Conclusion: Для начала рассмотрим результаты простейших тестов линейного чтения и записи. Очевидно, что винчестер работает достаточно быстро. Средняя скорость линейного чтения составляет 132.1 MB/s, а записи – 130.6 MB/s. Буферизированные значения получаются заметно большими: 243.6 и 215.7 MB/s соответственно.
