Hitachi Ultrastar 7K4000 4TB vs Western Digital RE 4TB

Two 4TB drives with 7,200rpm spindles go platter-to-platter

Hardcore PC performance fanatics are rarely satisfied. For example, when we were first given 1TB hard drives, we were excited, but wanted 2TB. Then we got 2TB and wanted 3TB, and so on, until we had a 4TB drive in the Lab. When that drive finally arrived, rather than rejoicing, we continued griping because the drive in question was a Hitachi 5K4000, which spins at a lowly 5,400rpm. The capacity was appreciated, but we wanted a drive with 4TB of capacity and a 7,200rpm spindle speed (we actually want a 4TB SSD, but that’s beside the point). Now the griping shall cease (for the most part), as we finally have 4TB 7,200rpm drives from Hitachi and WD. These fine specimens are the fastest and largest drives of their kind, so if you’re a data hoarder with a need for speed, one of these drives belongs in your rig.

Western Digital’s first 4TB SATA hard drive is the one to get if you have a lot of data (and money).


Patriot Pyro SE 240GB Review

Back in October 2011, we reviewed the 120GB Patriot Wildfire, the company’s first SF-2281-based SSD. With 32nm Toshiba asynchronous NAND, the Wildfire was a solid, if unremarkable, drive—awesome compared to nearly every other drive, but not quite up to the standard set by Corsair’s Force GT, OCZ’s Vertex 3, or OWC’s Mercury Extreme Pro. With the Pyro SE, Patriot hopes to change that.

The Force GT, Vertex 3, and Mercury Extreme Pro have one thing in common that the Wildfire lacked: 25nm synchronous NAND. Now a Patriot drive has the same stuff. The 240GB Patriot Pyro SE uses 16 128Gb modules of Micron 25nm synchronous NAND. Can the smaller process and synchronous NAND help the Pyro SE keep pace with the best SF-2281 SSDs on the market?

Yes. The better NAND pushes the Pyro SE past its stablemate and into the rarified air at the top of the SandForce-powered heap. With sequential read and write speeds at 482MB/s and 300MB/s, respectively, as measured by CrystalDiskMark, the Pyro SE is about as fast as the OWC Mercury Extreme Pro, and its 4KB random write speed, at over 91,000 IOPS, is the fastest we’ve ever seen from a 6Gb/s SATA drive. The synchronous NAND makes the most impact on sequential write speeds, offering a 40–50MB/s boost over the asynchronous NAND in the Wildfire.
