Shoot Out: Intel X25-V 40GB SSD vs. WD3200BEVT HDD vs. Pretec 8GB SSD , Bonnie++ Benchmarks
We've already sold a handful of these Intel X25-V SSDs to customers and listed them on the website. V is for value and it is slower than the X25-M but still boasts a decent theoretical read speed (175MB/s), compared to the Kingston SSDNow value line that is 100MB/s. Albeit, this is alongside a very low write speed (40MB/s). The write speed would seem to be comparable to a 5400RPM hard drive and we're pitting against one our favourites the Western Digital Scorpio Blue 3200BEVT, a very quiet 320GB 2.5" drive that doesn't have the whine that Seagate laptop drives do. But its' about 20% less expensive than faster SSDs (like the ATP reviewed below) and offers 40GB of space instead of 32GB.
Update: added the 8GB Pretec SSD (actually a CF card inside a SATA enclosure) that we sell with the T1.
I installed Lucid Lynx (Ubuntu 10.04 Alpha 2) and bonnie++. Results are below (all in MB/s)
- Block Output on SSD: 43.735 MB/s
- Block Output on HDD: 82.322 MB/s
- Block Output on CF: 8.160 MB/s
- Rewrite on SSD: 31.022 MB/s
- Rewrite on HDD: 34.232 MB/s
- Rewrite on CF: 10.793 MB/s
- Block Input on SSD: 211.938 MB/s
- Block Input on HDD: 84.112 MB/s
- Block Input on CF: 53.330 MB/s
- Random Seeks Per Second on SSD: 3674
- Random Seeks Per Second on HDD: 162.7
- Random Seeks Per Second on CF: 2167
No surprise but Random Seeks is where SSDs just kill it - no stupid moving platters to spin up. On the other hand they are reasonably matched elsewhere and the hdd is a little more than a third of the cost. Will update shortly with our Fujitsu 40GB drive since these are the 3 we use across our product range.
Fanless Atom D510 Processor in Aleutia D1 and P1 Tomorrow
We've already blogged about the D510MO Pine Trail motherboard with lower power consumption and a well thought out heatsink to keep the processor passively cooled. Unfortunately it does not work with Ubuntu out of the box - you have to flash the BIOS at least for 9.10 - but of course Aleutia does that for you before shipping it as part of our free OEM install of 9.10.
We've finished the stress testing of the board and will be offering it in our D1 and P1 starting tomorrow (soft launch tonight). Both feature much lower power consumption. With the D1 we're switching from the Compucase 8K01 case we (and lots of other UK system builders) relied on before to a new, fanless model from Taiwan that is is 2/3 the size. The 8K01 has an internal brick adapter but relies on a cheap 5cm fan to keep it cool, resulting in noise, and meaning there's just an IEC input not a DC input. Moreover, with two of the units, that noise increased over time which just isn't acceptable. Now it will be fanless and have a 19V DC input.
The P1 is still aimed at sailboats and marine customers and so has a 6-26V DC Input with a 40GB hdd or 40GB Intel X25-V SSD (nothing larger is needed for sea navigation). It will be in a wall mount case with the option of a extra Gb lan port, making it ideal as a server. We've also dropped the price £80 and will now offer Win7 with it as well.
