PCPer File Copy Test
Our custom PCPer-FC test does some fairly simple file creation and copy routines in order to test the storage system for speed. The script creates a set of files of varying sizes, times the creation process, then copies the same files to another partition on the same hard drive and times the copy process as well. There are four file patterns that we used to try and find any strong or weak points in the hardware: 10 files @ 1000 MB each, 100 files @ 100 MB each, 500 files @ 10 MB each and 1000 files at 1 MB each.
Most of these enterprise units are on the slower side when it comes to file creation, a heavily sequential operation, mainly due to firmware more optimized for consistency in random IO.
This test does large bulk file manipulation, which forces the EVOs to write at their TLC speed. That said, they perform very well and are able to perform very well overall. The (de) optimization that was causing slower creation on the older 840 and 840 Pro appears to have been corrected in the new controller.
Thank you for the quick
Thank you for the quick review sir. Personally I would call this a no question automatic upgrade for a new PC build. I’m interested to hear your thoughts on where this stacks up in the grand scheme of things.
If the pricing holds (and
If the pricing holds (and that's a big IF since I have yet to see sub-$1/GB pricing hold), the EVO will become my default recommendation for everything but the most demanding enterprise use.
Then let us hope with fingers
Then let us hope with fingers crossed that the price roughly holds (within 10 – 20 dollars). Much appreciated sir.

No hard date, but I'd imagine as quickly as they can get them out there.
Great review.

Great review.
As someone who is about to jump onto the SSD train;
1)It looks like several SSD makers are releasing new products now/very soon (so is it better to wait?)
2)I personally like the Corsair lineup, anyone heard anything if they are exiting the market?, seems like their SSD market is getting scarce.

Otherwise, love the article and insight!

LOL PCMO5? What the hell? and Iometer 2006? ROFLSAUCE! Its like I ran into an ’80’s website. Does your SSD wear parachute pants too?
If a tool works to accurately
If a tool works to accurately assess a product, why does it have to be made very recently?
An older product is also well understood and allows accurate comparisons to previous products that also tested with the same tools.

Is there any benefit these
Is there any benefit these days (performance or stability) to having one SSD for OS, another for programs and a third for data? Back in the day I used to have the OS on its own partition or even different drive, so it wouldn’t get all fragged up. I currently have a 120GB OCZ Vertex3 for OS, 1TB Samsung Spinpoint for progs and 500GB WD Black for data and trying to eliminate spinning drives for new build.
Hey Allyn, thanks for the
Hey Allyn, thanks for the great review. It looks like the bug you caught to get this review out may have been worth it, and I hope that you get well soon! How well do you think these drives will perform in a RAID-0 setup with say an Intel controller on either Ivybridge or Haswell systems?
They should be just fine, so
They should be just fine, so long as the partition is correctly aligned (not an issue for Vista and newer). There may be a slight performance hit due to TRIM not passing through to a RAID-0 (which is still a mixed bag as far as it actually working), but it should be minimal impact for regular usage.
I think in the case of
I think in the case of workloads with very little writing like a file server, the 840 EVO and similar SSDs could be an interesting replacement for something like this: http://accessories.ap.dell.com/sna/productdetail.aspx?sku=400-20233
With a significantly lower $/GB and better read performance.
Is there a concern that the
Is there a concern that the flash in the turbowrite buffer is going to die early? or does it get load balanced around the drive? I was sort of expecting the buffer to actually be SLC, but if it is just making TLC operate as SLC is that functionally equivalent to it being SLC?

If they don’t fix the problem you should downgrade the review to Bronze or worse. 🙂
I bought this drive on PCPERs recommendation and now I’m pissed.
