Bonnie++ Benchmarking

You are currently browsing the archive for the Bonnie++ Benchmarking category.

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.

We’ve been using these SSDs from KingSpec in China for some time and that I’d put a benchmark.

Bonnie++ Benchmarks (all in MB/s):

Sequential Character Output: 8.266

Block Output: 36.078

Rewrite: 17.452

Sequential Character Input: 11.174

Block Input: 121.445

Random Seeks Per Second: 2266

We love SSDs, particularly the Intel X25-M 80GB which I’ve blogged about before. But that’s expensive (£134 wholesale) and now Kingston’s released the SSDNow with pretty solid write speed of 80 MB/s and a nice 64GB capacity. eBuyer, Overclock.co.uk are selling these for about £92 ex VAT and wholesale is only 12% less.

Boot Time: From Grub to Usable Desktop it boots in 24.0 seconds.

Bonnie++ Benchmarks (all in MB/s):

Sequential Character Output: 11.609

Block Output: 21.171

Rewrite: 10.513

Sequential Character Input: 12.184

Block Input: 130.831

Random Seeks Per Second: 5119

Basically the Samsung F3 hard drive crushes it and offers 8 times the space at one third the price, i.e. the Kingston SSD comes out 24 times more expensive per GB. However, at Random seeks (access time) it’s 29.5 times faster which is kind of crazy. The Samsung 3.5″ hard drive, by contrast was just 1.3 times faster than the 2.5″ Fujitsu Drive.
