Is this the world’s fastest and safest notebook hard drive?

Hitachi Global Storage Technologies has announced the world’s highest-capacity, highest-performing notebook hard drive and it will feature in Dell and Alienware systems. The 2.5”, 200Gb, 7200rpm, Travelstar 7K200 brings twice the capacity of its predecessor as well as a 22 percent performance hike. Using Hitachi’s third-generation perpendicular magnetic recording technology, the 7K200 also comes with optional hard drive level bulk data encryption to guard against data loss.

Rather than protecting your data on a hard drive using software-based encryption or a system-level password, this scrambles the data using a key as it is being written to the disk and then descrambled with the key as it is retrieved. Encryption at the hard-drive level represents a more sophisticated approach to securing users’ data and is generally considered to be as impenetrable as you are likely to get right now. Just as importantly you get a secure data erasing process into the bargain because bulk data encryption makes data-erasing unnecessary. How so? Because by simply deleting the encryption key the drive is rendered unreadable and the data safe from prying eyes.

Hitachi tells me that the drive is 18-33 percent faster in application performance than competitive 7200 RPM and 5400 RPM 2.5-inch hard drives, which means faster file copying and document retrieval, better graphics, faster game performance. It has low acoustics to offer a richer audio-listening experience, and a 5400 RPM power parity means users don’t have to give up battery life for the higher performance. 350 Gs operating shock tolerance gives users better data protection from vibration, bumps and drops than any other competitive hard drives, while 4.2 ms average latency and 10 ms averaged read time coupled with 11 ms average write time round off the impressive performance specs.

Expect to pay around $249 in the summer when the drives become generally available.

Good catch, — the Travelstar 7K200 offered an optional drive-level “Bulk Data Encryption” feature, but the security question raised by is the important one: where the keys live and how they’re protected. The vendor literature calls out an encryption/quick‑erase option, but does not publish low‑level key management details that would let an auditor confirm there are no hidden master keys or debug interfaces left open. ()

Physical access attacks can defeat a poorly implemented self‑encrypting drive (SED). Academic and industry analyses have shown real drives where the user password was not cryptographically bound to the data‑encryption key, or where firmware/debug access allowed bypassing the protection — so simply trusting “hardware encryption” without vendor validation is risky. Microsoft and CERT guidance from the larger SED analysis era recommends caution and, where practical, preferring software encryption until you verify the drive’s implementation and patch status. (kb.cert.org)

Practical advice for Linux/Unix users: use well‑audited, open solutions (dm‑crypt/LUKS via cryptsetup) for any data that must remain confidential — they’re transparent and maintained by the community. If a drive’s hardware encryption is needed for management reasons, insist on an industry standard (TCG Opal/SSC) and vendor evidence of implementation/validation, keep firmware current, and manage SEDs with community tools (for Opal drives) rather than trusting opaque vendor tooling. (github.com)

So: yes, the 7K200’s BDE was an attractive feature in 2007, and ’s point about firmware reset/quick‑erase is the right line of thinking — but “world’s safest” depends on the cryptographic design and implementation details you can’t see from the spec sheet. For high assurance, use open, auditable crypto (LUKS) or only rely on SEDs that explicitly document standards compliance and independent certification. ()

Whew, drives are getting huge for laptops. My little 60GB seems so much smaller than it did a few years ago...

I wonder how well the security would work though. If someone were to steal the drive, keeping the encryption keys in hardware (or firmware?) would still allow them to decrypt the data, wouldn't it?

i think it would

i think maybe you must be able to reset the firmware key and thats what the OP means
