Running An Encrypted LVM In Ubuntu 10.10

Back with Ubuntu 7.10 an option was added to Ubuntu's alternate CD installer to easily setup an encrypted LVM during the Ubuntu installation process. This would better protect your personal data in the case your laptop or mobile device was ever stolen or misplaced as the Ubuntu Linux installation cannot boot if the encrypted LVM cannot be mounted with the encryption pass-phrase. Of course, encrypting the entire root partition can cause a performance penalty as some of our earlier results have shown while introduced in Ubuntu 9.04 was support for home encryption where only your SWAP and home folder is encrypted and this is done using eCryptfs. This continues to be Canonical's preferred method of encrypting user data with it being available from the standard Ubuntu installer while even three years later only the install-time encrypted LVM support can be accessed from their alternate installer. For those serious about encrypting their disk drive on Linux, we have new benchmarks from Ubuntu 10.10 showing how an encrypted LVM will affect your file-system performance.

New Linux Benchmarks Of SilverStone's HDDBOOST

Back in April we reviewed the SilverStone HDDBOOST, which was an innovative product from this manufacturer known for their computer cases that allows you to pair a solid-state drive and a hard drive in an attempt to experience the best of both worlds when it comes to storage performance. The purpose of the HDDBOOST is to increase the disk performance by enabling SSD speeds on the host hard drive while reducing write times to the SSD. From our Linux tests in that article we had a hard time getting this small device to provide any measurable performance gains, but in fact it caused some performance losses. In June, we then had results from SilverStone when they tested it under Ubuntu Linux with the Phoronix Test Suite. Since then we have been trying out a new HDDBOOST unit and it now seems to be working right.

OCZ Vertex 2 60GB SSD

As solid-state drives are becoming very popular with enthusiasts and a common choice for those interested in high-performance data storage, at Phoronix we have reviewed many SSDs from OCZ Technology including the Agility, Agility EX, Vertex, and Solid 2. Today we are reviewing the next-generation Vertex SSD, which is the Vertex 2, and it promises to offer much faster reads and writes, is rated to last an extra 500,000 hours beyond the 1.5 million hour MTBF of the original Vertex, and is available in capacities up to 480GB.

Btrfs, EXT4 & ZFS On A Solid-State Drive

With the benchmarks recently looking at the performance of ZFS on FreeBSD versus EXT4/Btrfs on Linux having generated much interest and a very long discussion, this morning we are back with more benchmarks when running ZFS on FreeBSD/PC-BSD 8.1 and Btrfs and EXT4 on an Ubuntu Linux 10.10 snapshot with the most recent kernel, but this time the disk benchmarking is being done atop a high-performance solid-state drive courtesy of OCZ Technology and the CPU is an Intel Core i7. The drive being tested across these three leading file-systems is the OCZ Vertex 2 that promises maximum reads up to 285MB/s, maximum writes up to 275MB/s, and sustained writes up to 250MB/s.

OCZ Solid 2 SSD

We have reviewed a number of OCZ solid-state drives at Phoronix including their Vertex, Agility, and Agility EX series. In this review we are taking our first look at OCZ's new Solid 2 SSD series. The Solid 2 series is part of OCZ's value-based SSD line-up, but they do offer a surprisingly good level of performance.

SilverStone's Linux Results For The HDDBOOST

Back in April we reviewed the SilverStone HDDBOOST, which was a unique device that allows a solid-state drive to be combined with a traditional hard-drive to create a "virtual super storage solution" whereby SSD transfer speeds are enabled on the host hard drive while the write times to the SSD are reduced. Unfortunately, we were not able to get this unique contraption working well under Ubuntu Linux even though theoretically it should work just fine. However, SilverStone seems to have the device working within their labs and it is producing some interesting results.

SilverStone HDDBOOST

While SilverStone has long been revered for their range of uniquely high-end computer enclosures like the Fortress FT02, Temjin TJ10, and Sugo SG04 all with original designs, occasionally they have dabbled with other products outside of their computer enclosure and power supply expertise. We previously have reviewed such products like the SilverStone Raven mouse and an RFID-secured SSD/HDD enclosure, but their newest peripheral in this area is by far the most unique product that we have encountered from SilverStone. The SST-HDDBOOST product allows you to connect a solid-state drive and a traditional hard-drive via their custom PCB to experience the benefits of both types of storage.

OCZ Zee 4GB

A few weeks back we reviewed the Corsair Flash Voyager 32GB. This 32GB flash drive was very nice just like Corsair's other flash memory products and it boasted an impressive capacity with great read/write speeds, but its price at over $100 USD is not for everyone. For those that can make do with a smaller capacity and are looking to just spend a few dollars in comparison, there is the OCZ Zee. The Zee flash drive is available in capacities up to 16GB, has a more conventional housing, and is backed by a two year warranty (in comparison to Corsair's ten-year backing), but the prices for the Zee USB 2.0 drivers are much more affordable.

Eagle Tech Consus USB 2.0 / eSATA Enclosure

It's not often that we steer away from our graphics card, motherboard, processor, driver, and software benchmarking to look at other products like computer peripherals, but occasionally we are up for it, particularly when it's an offer from a manufacturer we have never heard of before with running their products on Linux. An example of this is Eagle Tech Computers, which is a US-based company that makes a variety of drive enclosures, speakers, and power supplies. Eagle Tech is no SilverStone Technology, but we decided anyways to check out their Consus ET-CS2PESU2-BK, which is a 2.5" external enclosure that offers USB 2.0 and eSATA connectivity.

Corsair Flash Voyager GT 32GB

It was nearly five years ago that we tested the first Corsair Flash Voyager that offered just 512MB of memory, but at the time it was quite a modest amount of storage for a USB 2.0 flash drive. The Flash Voyager was unique though from the other flash drives on the market in the respect that it was waterproof and far more durable than any other flash drive. As time has passed, more manufacturers have adopted designs similar to that of the Flash Voyager. The capacity of flash drives has also increased and we have tested out the 4GB, 8GB, and 16GB versions of the Flash Voyager and their newer and faster Flash Voyager GT series too. We have also reviewed other innovative Corsair flash memory products like their Flash PadLock and we happened to be the first publication to deliver a review of the Corsair Flash Survivor GT. Now though we are back with the Corsair Flash Survivor GT as we test out one of their newer versions with a 32GB capacity.
