Posted April 9, 2008 · Report post I came across this interesting drive: 32gb 2.5" SATA SSD for $249 I am thinking about putting 24 of them in a raid 0 with an areca 1281. There is even this nice 2U rack for them. Together the drives should be capable of writes @720mb/sec (24*30) and reads @2,880mb/sec (24*120) although I'd expect the areca to top out around 800mb/sec reading or writing. This comes out to about $8/GB compare to say a similar setup using mtron or memoright drives which are ~$30/GB The only difference with the mtron and memoright drives is that they offer much higher write performance per drive. But by the time you add enough of them to a RAID to have any significant capacity the write performance is at about the controller's limit. This seems like the smart way to do SSD RAID, am I missing anything? Share this post Link to post Share on other sites
Posted April 9, 2008 · Report post A few things you might want to consider: -1 year warranty vs. 5 year -Unproven brand/source -Benchmarks not comparable (I've never heard of HDBench). There is data on SSD's with HDTune, HDTach, ATTO, not HDBench -No quantified access times (They mention 0.4ms, but...) -Only 18 available when I checked (so your dream of 24x might have to wait) Share this post Link to post Share on other sites
Posted April 10, 2008 · Report post I agree with the things that poisondeathray mentioned above. I wouldn't bother personally. They are cheap for a reason i.e. they're rubbish. I reckon if you benchmarked these drives using a proper HD benchmarking program and used NTFS (rather than FAT32) the read/write speeds would be lower than the ones he has stated (which incidentally is ~21MB/s when Windows is installed on the SSD).

Posted April 10, 2008 · Report post I had a quick look on Google and found the OCZ OCZSSD2-1S32G SSD which has read/write speeds of 100MB/s and 80MB/s respectively. Although each drive costs around $569.00 you would only need 5-6 drives to match the write speed of those eBay SSDs, or for just under $5,700 you could get 10 drives for a combined write speed of around 800MB/s! It's also worth mentioning that the OCZ SSDs are certified for use in a RAID array whereas the eBay SSDs are not. Share this post Link to post Share on other sites
Posted April 10, 2008 · Report post The OCZ drive is attractive.. I agree about the ebay SSD's I'm suspicious of the specs in the description. The downside of getting less higher performing drives of course is the total capacity will be much less: 24x ebay SSDs = 768gb whereas 6x OCZs = only 192gb (insufficient imo) Share this post Link to post Share on other sites
Posted April 11, 2008 · Report post If you aren't in a hurry I'd wait until Intel enters the SSD market in a few months. I anticipate a surge of competitive pricing from everyone, not to mention the Intel product might be class-leading. Think about 4x 3.5" 160gb. Share this post Link to post Share on other sites
Posted April 11, 2008 · Report post Currently SSDs are still way overpriced. Flash in Sd-cards or thumb drives (even those fast ones) is well below 4€/Gbyte (the slow ones <3€/GB). The only SSDs in that price range are _really_ slow (<10Mbyte write, ect), while all the fast ones are >10€/GB. Just as a comparison: MOBI drives are more expensive per GB than DDR2 RAM.
