At the request of Phoronix readers, and that the default I/O scheduler may change, here's a comparison of the CFQ, Deadline, and Noop schedulers on three systems and covering both rotating media (HDD) and solid-state storage (SSDs).

After recently testing the SilverStone RVS02 2.5-inch SATA enclosure, here is a look at the SilverSton TS07 3.5-inch SATA 3.0 SATA external enclosure.

For those in the market for a 2.5-inch external hard drive enclosure that supports Serial ATA 3.0 and works well with Linux while being a well-designed and effective product, being looked at today on Phoronix is the SilverStone Raven RVS02 disk enclosure.

Last month I wrote a review on the OCZ Vertex 3 240GB solid-state drive, which was a very impressive Serial ATA 3.0 SSD. The performance of this solid-state drive was terrific and a huge improvement over previous-generation SATA 2.0 SSDs and over SATA 3.0 hard drives. All of that testing was done when the drives were formatted to the common EXT4 file-system type, but in this article are more benchmarks from the OCZ Vertex 3 as it's tested with Btrfs and various mount options.

It's been a while since last providing a Phoronix review of a solid-state drive from OCZ Technology, but now with Serial ATA 3.0 support becoming more prevalent on modern Intel and AMD motherboards, they have been releasing a number of updated products to take advantage of SATA 3.0. In the review we have our hands on an OCZ Vertex 3 240GB SSD as we see how this SATA III SSD performs under Ubuntu Linux.

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.

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.

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.

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.

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.
