I recently bought a new 2TB SSD to handle my virtual machines. This one is m.2, was previously using 256 GB SATA drive. Nothing against SATA, it just can't compete on speed with m.2.
I am running Windows 7 x64 both as a host and a guest VM using VMWare Workstation v9. Here are the figures of Windows Experience Index for each instance, so you can estimate virtualization efficiency: Host Windows 7: Guest Windows 7 - VMWare Workstation v.9: Guest VM is allocated 2 cores, out of 4 cores total on my Intel i7-4770. As you probably have heard, Windows 7 uses logarithmic scale for its performance score.
First benchmarked using latest Passmark. Then did some tests with latest Aida64. What's interesting here is that both processor and memory speed keeps fluctuating. I have not found a good explanation for this behavior.
Hardware: HP ProLiant DL380 G7 Mushkin Enhanced Chronos SSD - 2.5” 240GB SATA III MLC (MKNSSDCR240GB) (RAID1) 2 x Seagate Savvio 10K.5 hard drive - 300 GB 2.5” 6Gb/s SAS 10000 rpm 64 MB Buffer (ST9300605SS) Benchmarked with CrystalDiskMark 3.0.1 x64 on Windows 2008 R2 Std + SP1.
Here are the results from CrystalDiskMark 3.0.1 (x64), connected over USB2.0 and USB3.0 respectively. Very diligent with specs, and actually performing better at USB2 than advertised by ADATA. Looks like a good deal for 30$.
Did not have a chance to do a full performance test on this machine (VX4618G-Ei7260W). Memory, however, works quite well for a $700 PC, benchmarked with Aida64.
I recently did power consumption test for my Acer 1810T, which I bought a year ago. OS desktop is Windows 7 Home + Aero enabled. I used Kill-A-Watt power meter.
I recently had a Microsoft workshop session and became excited about parallel for/foreach/etc. There we got a solid 60% of efficiency. It means that whenever number of cores increases by 2x, performance is boosted by 1.6x.
I ordered mine on 12-Apr-2010, and it’s December now, so it’s ~6 months of light use, 135 days = 4.5 months of uptime and an average 6GB of writes per actual day, which translates in just a bit over 1TB of writes. The drive already has 1 bad sector, which was remapped about a month ago. Decided to test performance with AS SSD Benchmark, and here’s the screenshot with results.
Hardware - HP Proliant DL380 G5, two disks, one is Intel SSD and another one is HP SCSI 15K drive, each running as RAID0. Software - IOMeter, latest version. File system - default NTFS partitions were setup, with Intel being a system drive. It might sound like a bit of overhead (bringing incorrect measurements), but honestly, I don't think it would really matter on such speeds and IOps. Controller caching - 25% read/75% write.
