OCZ Preps 1TB 800MBps SSD

Ok, so I expected the boundaries of SATA3 to last longer than that...

Just a day after Seagate wows us all with the ability of SATA3 (also known as 6Gbps SATA) to increased speeds to 600MBps OCZ blows this bandwidth apart with an SSD cooked up in Hades itself.

Called the 'Z-Drive' it is a completely bonkers and yet utterly brilliant idea: a one terabyte MLC-based SSD with 256MB of local cache and hardware-based RAID controller. It plugs into a PCI Express slot to eliminate any bandwidth boundaries and OCZ preliminary tests show it managing 600MBps read and 500MBps read. That said, OCZ also claims some benchmarks have seen it nudge 800MBps.

I repeat, completely bonkers and yet utterly brilliant.

Of course at this stage you cynically reply 'But it's just a concept'. Actually no, OCZ is making the dreams of the rich and famous come true by making low numbers of production units available this year.

Pricing? I'll let OCZ phrase this one: "Definitely for the high-end crowd, the Z Drive won't come cheap..."

Yep, you can't afford it.

By the looks of it, the biggest issue is fitting it in your case - it looks like it needs a vacant slot on either slide of it to fit!

Well if you think thats fast then check out Samsungs little experiment. 2GB per second (yes bytes not bits)!

> it managing 600MBps read and 500MBps read

WOW!, I wonder how fast the write is. :)


March 10, 2009, 5:34 pm

LOL. Oh the write is 600Mbps write and 500Mbps write, Keith.

Isn't this like the days of i-ram...just a bit different?


March 10, 2009, 6:36 pm

Well that was just a RAM drive, wasn't it? So you'd lose all the data on it when it wasn't powered, whereas today's SSDs use non-volatile memory.

Correct me if I'm wrong, but didn't they just use 4 256GB SSDs? So technically we still won't be seeing true 1TB SSDs for a while yet.

If you use a full blown hardware RAID card from the likes of Areca then similar numbers can be achieved by mere mortals apparently.

Am experimenting with a 4 x SSD (Samsung SLC) RAID 0 (Intel ICH10) setup at the mo. Getting 7.9 on the Windows 7 "experience" index (yes I'm playing again though this time on a new system). Gonna run some more benchmarks later this week.

utilising multiple drives in a raid array will most defiantly be quicker than having one big 1TB drive. plus cheaper to produce.

@smc8788 I think you could get battery-backedup versions so it wasn't completely flawed.

Specifically it's a PCI-E 8x slot, so quite a few motherboards won't fit it (you either need a spare 16x slot operating at 4x or above or a rare 8x slot).

PCI-E 1x is only 250MB/s(1.0) or 500MB/s (2.0).

@smc8788: What's a 'True' 1TB ssd? They're all made up of chips of smaller capacity so where do you draw the line between one and several SSDs? Different boxes? But that's not the case here...
