Corsair Accelerator Series 30GB Cache SSD Review – A Second Wind For Your System

CRYSTAL DISKMARK VER 3.0.1c

CrystalDiskMark is a disk benchmark utility that measures performance for sequential and random reads/writes of various sizes for any storage device. It is useful for comparing the speed of both portable and local storage devices.

Roughly the same performance ATTO recorded, but clearly limited by the SATA 3Gb/s interface. 4K speeds are much lower than what we would see from a typical SSD, but still not too shabby overall.

ANVIL STORAGE UTILITIES VER. 1.0.44 RC1

Anvil’s Storage Utilities is a powerful tool that is designed in to provide a simple means of assessing the read and write performance of a Solid State Drive or Hard Disk Drive.

Again, slow 4K read speeds, but otherwise massive performance gains across the board versus what a normal hard-drive can churn out.

PCMARK VANTAGE PROFESSIONAL X64 1.0.2.0

PCMark Vantage measures PCMarks as an indicator of performance across a variety of common tasks such as viewing and editing photos, video, music and other media, gaming, communications, productivity and security.

Here is where the Accelerator cache SSD shines brightest. If you recall, the package states up to 5x the performance of a hard-drive alone. We certainly see that claim backed-up here!

I got this SSD and I think that with time there is a degradation in term or performance (probably from NVELO). I bought it more than 2 months ago and this week I uninstalled NVELO and reinstalled it. I did run ATTO Disk Benchmark, before that I change anything, after while I was on my HDD only and after the reinstall. Before the reinstall: 94MB/s read and 144MB/s write (50MB/s more in write? Seems strange to me) On HDD only, I got : 76MB/s read and 75MB/s write After the reinstall: 205MB/s read and 208MB/s write. (I also have a… Read more »

Hi Golden, Sorry for the late reply. I have been running Dataplex/Accelerator for about a month now. I took a quick test and here are the results: http://bit.ly/MypDRZ Not a big loss of performance, and everything seems to be running well for me. As I’ve said in the review, I’m not a big fan of Dataplex and it still needs some work, because there are bugs like the one you have. I noticed that after waking-up from sleep/hibernation, and after a system restore, the cache gets messed up and starts under-performing and bogging down until you’re forced to reboot. I… Read more »

Hi Deepak,

My computer is regularly in sleep mode so maybe that’s why it got so slow. But when I did the test it had reboot before so it’s just strange. It looks like when a computer got in sleep mode even if rebooted it still got a little loss and with time it becomes a big loss. For me, my loss are not from a system restore since I have not use that for more than a year.

Thanks for the information.

No problem, and yes that is very unusual. The only answer I can think of is, perhaps the system considers the hybrid set-up as a hard-drive set-up (since the SSD isn’t present in disk management), and still uses the normal healthy functions meant for a hard-drive (defragmentation, for example), which could be leading to drive/cache degradation. I can’t really say as I don’t know how Dataplex is built from the ground up, but just theorizing. The good thing is that the new version is released (1.1.3.7): http://www.corsair.com/accelerator-software/ http://www.nvelo.com/dataplex-download/corsair/ReleaseNotes_v1.1.3.7.txt My favourite updates: – Dataplex Collect Logs – System information collection utility… Read more »

I bought a 30Gb Corsair Accelerator a few weeks ago and changed the SATA to ACHI as recommended and installed Dataplex etc. At first all was ok untill one day the PC would not boot. I treid all ways to fix it but in the end rebuilt it from an image I created before installing Dataplex. The problem now is that the Dataplex software will not allow me to use the SSD. It says ‘not recognised’ but it is recognised by the PC. There is obvious a block on using it twice and that is unfair to anyone who has… Read more »

I’ve got a stupid question about this test and Dataplex. When you mention “primary drive” or “single drive”, you’re speaking about logical and/or physical drives (hard drives and/or partitions). If I have 1 single HDD but 2 partitions on it (C: and D:), I can only cache one of these. Not both. And it must be the boot one. Is that correct?
What if I have my system on C: and my games dir on D:? (I think I can guess the answer to this one).
Thanks in advance to anybody who takes the time to answer to this one.

At present, this caching software ONLY caches the boot drive of the system.

I would like to mention also that partitioning a hard drive while it may prevent fragmentation it also will slow down the overall performance by increasing the average seek rate. Using the right software you can place your files that you use the least often to the inner tracks. It is estimated that people use 20% of their files 80% of the time. Partitions are great for storing back up images or similar files but overall are going to be unwanted if you access that partition on a daily basis. It’s a similar concept to windows “superprefetch” and the caching… Read more »
