Hitachi Deskstar 5K4000 Review

Finally, a 4TB hard drive. That’s one more than three!

MOST OF US DON'T NEED 4TB hard drives. Most of us don’t even need 3TB drives. Unless you create, edit, or store lots of high-definition video; have backups of all your machines; have a massive lossless audio library; or…. You know what? Maybe we do need 4TB drives. After a couple of years making do with puny 3TB drives (like animals!), it’s time to get 25 percent more stuff into our 3.5-inch drives. Though other drive makers offer 4TB external drives, Hitachi GST is the first drive maker to give you 4TB on the inside. And didn’t your mother or mother-equivalent teach you that it’s what’s on the inside that counts?

We’ve been expecting 4TB drives since Seagate’s 1TB/platter 3TB drive in the January 2012 issue, but the four-platter 4TB 7,200rpm drive we’ve been dreaming of isn’t here yet. Instead, we get Hitachi’s Deskstar 5K4000, which packs a full four terabytes into a standard 3.5-inch drive, but on five platters, not four. The platters have a maximum areal density of 443Gb per square inch. The 5K4000 has 32MB of cache, a 6Gb/s SATA controller, and a spin speed of 5,400rpm.

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.

Intel 520 Series 240GB Review

For every season, there is a spin. Intel’s first consumer SSDs, the X-25M series, didn’t have the fastest performance, but they gained a reputation for reliability. We had high hopes for Intel’s 320 Series SSDs, which turned out to be really great 3Gb/s SATA drives, at a time when everyone else was shipping 6Gb/s drives. When Intel did ship a 6Gb/s SATA drive, the 510 Series, it used a Marvell controller, not an Intel one. Well, Intel has finally released its second 6Gb/s consumer SSD series, and it’s powered by… SandForce?

Yep. The 520 Series may ship in Intel’s familiar 7mm aluminum chassis with a 2mm black spacer, but inside it’s running the same SandForce SF-2281 as everyone else. It does use 25nm Intel synchronous NAND and Intel-validated firmware, which Intel says makes it better, faster, and more reliable than plain-Jane SF-2281-based drives.
