OCZ details Z-Drive R5 enterprise SSD, reckons it doubles speed of the R4
We've barely digested the carb-rich Z-Drive R4 and already OCZ wants to flaunt the next in its series of enterprise PCIe SSDs. The R5 sports an entirely new 'Kilimanjaro' controller platform (shown in the reference design above), developed in cahoots with Marvell and incorporated into each and every flash module that you might wish to add to the base card. These scalable controllers communicate directly with the host system, removing the need for an extra SATA RAID chip and thereby promising greater speeds -- especially as you pile on more modules. We won't get full specs until CES, but in the meantime OCZ has hinted at a doubling of the SandForce-based R4's performance, which could take us into the three million IOP realm. So long as the company also tackles the question of reliability on this new type of drive, then it'll likely be an easy sell. Check out the source link for more.
AngelBird's PCIe SSD solution brings breakneck speeds, achievable prices, 'incremental awesomeness'
PCIe SSD solutions tend to be two things: stupidly fast and stupidly expensive. With read performance of up to 1GB/s and writes happening at up to 900MB/s the Angelbird Wings solution certainly has the speed. And, at a starting price of $239 for a 16GB model, the pricing isn't too bad -- for this sort of setup, anyway. What you're getting for that money is an expandable PCIe controller board with slots for up to four SSDs of 120GB in size, each offering SandForce 1200 controllers. With one board you'll get pedestrian read and write speeds of just under 300MB/s. But, with each new drive you basically multiply that, with the maximum figures quoted above coming with four. Interestingly, the controller comes with its own onboard Linux flavor called Virtue, a full UI that you can boot directly into and get all your RAID ducks in a row. Full cost for a fully kitted out system with four boards? $1399, which is hardly cheap for a mere 500GB or so of storage, but is a solid price for 1GB/s performance.
