Yesterday Intel announced the Atom D425 and D525 platforms targeted for small storage servers. Both chips are 1.8GHz parts with Hyper-Threading. The Atom D425 is a single core with 512KB of cache (10w TDP) and the Atom D525 (13w TDP) being the dual core chip with 1MB of L2 cache.
The chips support both the DDR2 like the Atom D410 and Atom D510 did, but also support DDR3 SODIMMs. Generally speaking, DDR3 SODIMMs use slightly less power than their DDR2 variants. The TDP of the new chips is identical to the older D410 and D510 chips rated at 1.66GHz. Continue Reading

Many of this site’s readers have large storage requirements due to a focus on centralizing redundant storage for multiple client PCs. One common scenario is streaming video to client PCs. Personally, I use a mix of mainly micro ITX (mITX) platforms as HTPC streaming PCs. My typical configuration involves a mITX motherboard with a low power CPU, on-board GPU capable of accelerating popular video codecs, 4GB of RAM and a solid state drive. In fact, I have moved away from even including optical drives in these configurations because they tend to add cost without much value. Over the past few months, I have tried about twelve different mITX cases from approximately $35 to $150, and have found the Apex MI-100 mITX HTPC case to be a nice mix of value, functionality, size and feature set. To that end, I now own three of them and figured since I get questions about them quite often, I may as well do a short write-up. Continue Reading

Although Intel’s Atom CPUs have made a splash in the mini ITX space, many users prefer the small form factor yet want more computing power than the Atom can muster. In response to this need, motherboard manufacturers have started to build standard socket motherboards in small form factors such as mITX.
Over the past decade, features such as video, audio, and network interfaces have moved from occupying expansion slots to being integrated directly on the motherboards. For many users onboard video, audio, and LAN obviate the need for add-on cards in a system. With all of this basic functionality onboard, smaller motherboards have become possible, such as mini ITX.

As one would gather from my previous Intel Atom D510 and NM10 post, I am not the biggest fan of the current D510 Atom platform with NM10 chipset. ZOTAC, to its credit, did take a rather mediocre platform and build a solid board around it. The most probable use case is a streaming media HTPC (non h.264) to a legacy 720p display. The nice thing about the ZOTAC offering is that it has quite a few expansion options for a D510/ NM10 based system, and it is ready to go out of the box. Unlike other Intel and AMD platforms, the Atom D510 and accompanying heatsink do not need to be installed by the user. One can literally plug in a display, mouse, keyboard, RAM, storage drive(s), and 20-pin power source and start using the system. As a preview, my end conclusion is that the ZOTAC board is a great choice given the platform, but the Intel platform leaves a lot to be desired. Continue Reading

Out with the old and in with the new, but worse platform. I have been wondering about the Intel Atom D510 performance for quite a while now alongside the NM10 chipset. It is essentially Intel’s upgrade to the venerable dual-core Intel Atom N330. With the consolidation of features to the D510 and NM10 Intel was able to get rid of a power- hungry 90nm process component and deliver a reduced feature set in the name of lower power consumption. For low power file servers, the Atom platform is great. One will notice these days that Intel’s 32nm Clarkdale line has idle power consumption similar to the D510. Where the Atom CPUs really shine is in load power consumption. Unlike the Core i3-530 and Core i5-650 (and their higher clocked Clarkdale brethren), the Atom CPUs are somewhat famous for only adding a nominal amount of power consumption when being fully taxed versus sitting idle. That is why many of the NAS appliance vendors that run proprietary Linux distributions choose the Atom to do software raid parity calculations.
Sadly, Intel has decided to leave the NAS and HTPC markets out to look at other offerings instead of its Atom D510 platform. Continue Reading

After the Intel Xeon X3440 review, I wanted to see the difference between the X3440 and the Intel Core i7-860. Of course, I could have just purchased a Core i7-860, but instead I decided to get an Intel Xeon X3460 because it is essentially the same CPU, just with ECC support. For all intents and purposes, the Intel Xeon X3460′s performance should be identical to the Core i7-860.
The major difference between the Intel Xeon X3460 and the previously reviewed Xeon X3440 is clock speed. The X3460 runs at 2.8ghz while the X3440 runs at 2.53GHz. Price wise the 0.27ghz will cost another $120 or about 50% more depending on street price fluctuation.
To keep this comparable, I wanted to see a performance of the X3460 versus the other CPU’s I have tested for video encoding and transcoding on a Windows Home Server platform. Second, I wanted to have a server running Microsoft Hyper-V Server with Windows Home Server and Ubuntu 10.04 as guest operating systems running in Hyper-V virtual machines. In the end, I found that the Xeon X3460 was slightly faster than I had anticipated.

The Intel X25-V 40GB drive is well known to be one of, if not the best low-cost SSD on the market at the moment. The SSD is basically an Intel X25 G2 drive with TRIM support except with half the NAND flash memory and using only half of the SSD controller channels. The major impact is well known at this point, the Intel X25-V 40GB drives have poor sequential write performance that is approximately half that of the Intel X25-M 80GB. Of course, with two X25-V’s in RAID 0, write speed is essentially doubled and read speed goes well beyond a single drive.

OCZ’s Agility 2 120GB is a new generation of drive based on the SandForce SF-1200 controller. Unlike the OCZ Vertex LE and OCZ Vertex 2 drives, the Agility 2′s SandForce controller has an IOP limit artificially limited in firmware. With that being said, it is also cheaper than the Vertex 2 120GB and is still a very fast SSD, especially with compressible loads.
The short story of the SandForce controller is that it uses an internal encryption/ compression algorithm to write data to NAND faster than other drives. The SandForce based Agility 2 120GB is therefore fairly fast with compressed workloads (i.e. pictures, music files, zip files, ISOs, and etc) and much faster with compressible workloads such as office documents. Another major storyline is that SandForce is a fairly new player and the controllers are of unknown reliability. Finally, originally SandForce reserved much more space on drives in this capacity range for use in wear leveling, cache and etc. OCZ Agility 2 and Vertex 2 SandForce drives were originally 100GB but after being criticized for mediocre cost per GB and with little performance penalty moving from 28GB reserved (old drives were 100GB usable 28GB reserved) to 8GB reserved (new drives are 120GB usable 8GB reserved), the choice to enable the extra capacity was clear.

Intel’s 3400 chipset for its socket 1156 platform accepts CPU’s from the cheap Intel Pentium G6950 and Core i3-530 to the higher end Xeon X3430 to X3470 CPUs. Both Clarkdale and Lynnfield based CPU’s offer outstanding power consumption (for early 2010) at relatively low costs. After reviewing the Supermicro X8SIL-F, I purchased a competing (price wise) Intel motherboard to review, the Intel S3420GPLC. As I soon found, Intel also makes a good board, however it lacks some of the Supermicro’s features.

This weekend I woke up one morning and decided that I wanted to know if retail packaged drives had a lower DOA rate than OEM drives from Newegg. In all fairness, I think I was just trying to put off a 5am Saturday morning gym trip for a few hours. I ended up filtering Newegg’s hard drive category by internal drives of 1TB, 1.5TB, and 2TB in capacity. I then went through each result and recorded the quantity of reviews for each of Newegg’s awesome egg-scale along with a few other parameters. It turns out that Newegg did not have as much information on retail packaged hard drives as I had wanted, but I found some interesting results nonetheless. Anyone can do this survey, but hopefully this saves some time. For the most up-to-date information see Newegg.
