Micron put out a new SSD.
Although it looks pretty dang good, I would like to point out, Micron has yet to bench against the WD VelociRaptor 10k rpm instead of the 7200k rpm standard HDD.
For a gaming rig, the V-Raptor still outperforms SSD's on the majority of benches. The WD 150 V-Raptor does freakin great! The smaller the drive size, the faster it is. Most benches partition the drives to 32Gb for tests.
On the other hand, if you do a dual boot system like I do, then for everything else aside of gaming (video, graphics, music etc..) then by all means, add 2 of those Microns because they are steady w/large reads / writes w/ around 121Mbs as opposed to the V-Raptor that delivers about 97Mbs
Here are results of what the V-Raptor's Out Performing SSD's and other HDD's.
Read / Write performance:
It's obvious that the disk drives are at a disadvantage due to mechanical delays: The moves of the read/write heads as well as the rotational latency (it takes 6ms for a 10,000 RPM disk to spin once).
Random writes are the SSD's achilles heel because of it's erase blocks, so performance is not nearly as good as the random reads. Disk drives on the other hand are able to cache written blocks and write them later. The partitioning trick helped with random writes as well, improving the score of the 32 GB Raptor partition by 20% and the score of the Velociraptor partition by 30% compared to the full disk.
The end result is that while the SSD is 11% faster than the 32 GB Raptor partition, the Velociraptor partition beats the SSD by 6% – however without partitioning the SSD is 13% faster than the Velociraptor (and 43% faster than the Raptor).
Sequential Reads / Writes:
1024KB, The Velociraptor is in the lead across all file sizes, it shows that it has a SATA-300 interface, whereas the Raptor and the SSD have a SATA-150 interface. Note that these high speeds (up to 238 MB/s) are reached thanks to the disk cache of the Velociraptor.
Random reads / Writes:
The SSD fares poorly in this test, because of its achilles heel "small writes". Apparently there are not enough (or not distributed enough) writes to make up for it with its access time advantage.
This achilles heel of the SSD is due to "erase blocks": Wherease a disk can write small blocks of typically 512 bytes in size, the blocks are much larger for SSDs. First, the block has to be read into the cache, the data changed in the cache, and the full block written back to disk. So small writes have a lot of overhead.
Large Reads / Writes:
Here is where we see the SSD out perform;
Both disk drives make use of their cache to buffer writes, and performance drops noticeably as the transfers become larger. The Veloricaptor writes 100 MB transfers at 117 MB/s, the Raptor at 84 MB/s.
The SSD writes about 132 MB/s no matter the transfer size.
My results:
Bang for the Buck : V-Raptor hands down.. as SSD's cost more.
The V-Raptor out performs an SSD for gaming until I can see proof otherwise.
Games are not dealing w/ large read / writes so that SSD performance there does not matter unless you have a dual boot rig like I said above or have an all around rig that does everything. Even then, it would do you better to dual-boot you your "everything rig".
For Gaming, I will stick with my 150 V-Raptor x2 (raid 0)
When I want to boot into the SSD for everything else, yes, I would use the New Micron C300 x2 (Raid 1)
