Reviews - Corsair Force Series F80 SSD: to RAID or not to RAID?

Quote:

Ever wondered how quick two SandForce-powered SSDs would be in a RAID configuration? We find out.

Read more.

In the synthetic benchmarks on the HDDs how does a RAID0 setup more than double the speed? How is that possible?

In one instance (Crystal Mark) two HDDs in RAID0 are 5000% quicker than one of those hard drives alone.

Presumably the cache of 2 drives in RAID 0 is big enough to ensure the whole queue can fit in it, whereas a single drive has to read from the drive itself at that much lower speed? i.e. the faster read speed is from cache. Im just guessing though...

What effect does the lack of TRIM have? Surely the performance will degrade over time?

What do IOPs relate to in 'real world' terms? Would be nice to have seen times for application/gaming/boot time as well as data transfer speeds.

Blimey! I can't afford/justify one SSD let alone enough to build a RAID array!

Just had to be done.

Does this mean that there is trim support in raid?

Final thoughts and rating

If you've got £175 to spend, it's hard to ignore the impressive performance of Corsair's F80 drive.

But that's a big if, as the majority of consumers are likely to be put off by a cost of over £2 per gigabyte

No, you're worrying too much. Anyone who's used one in W7, won't go back......

But I dunno if the TRIM thing is sorted in RAID either.

Zak, why just in W7, chief?

Wouldn't the TRIM function be done by the controller on the SSD so RAID doesn't matter?

Sorry Shooty*, this should have gone to Ksdp 37,,,and I should have gone to Specsavers!

Here are some real-life results from the Corsair F80 in Raid 0.
System is Asus Rampage II Extreme, i7 920@3.2 GHz, 12GB DDR3, running Windows7 Ultimate x64
Raid Stripe is 128k.
