Edge Memory PE236779 (PCIe SSD)

Recommended Posts

Please forgive me as I am awful new to building computers. I am actually a photographer building an overkill machine and I am a little hung up on PCIe SSD's.
I have narrowed it down to these two

RAIDR Express


Edge PE236779

My hesitation is that there is virtually no information on the Edge anywhere on the internet. I have tried calling EDGE but only got in touch with a bunch of voicemail boxes. A lot of different websites claim to have the Edge PE236779 for sale but not a single person has reviewed it anywhere. Where as the RAIDR is a ROG product and as I am using a new ASUS MB I know everything will be compatible. That being said the RAIDR is slower and smaller than the EDGE. Any and all information is appreciated.

If the choice is between the two, i would go with a Company ive actually heard about. in this Case Asus.

The Edge might be an awesome product, but with limited possibilites for support, i recon its some sort of small Taiwanese producer that might be gone, in the blink of the eye.

The ASUS product is pretty new to the market and I haven't seen a lot around it. Its hard to comment on reliability and performance from our standpoint.

What is the main draw to one of those products for your usecase? You might end up being better served by a single SATA SSD, or a couple through a modern RAID card. You'll likely get better overall performance, much higher capacity, and be in a better position for HDD expansion later on.

Darking: Thank you for your post, that is the same kind of thing I was thinking.
Kevin: I totally agree with you that the products are new and I would prefer that they be more consumer tested. The biggest draw for the PCIe ssd was the read and write speed with a single component (The Edge claims Up to 2150MB/s (read) / 1950MB/s (write)). When I shoot a wedding I end up editing upwards of 3000 large files and I'm very much trying to speed up every step of my computer. I currently ate up all my onboard SATA connections with CD/DVD burners and CF card readers. I'm aware that I can gain additional SATA connections using a PCIe slot I was just hoping to keep things simple. Is RAID difficult to setup?

It's not hard and is probably a better option for you than the solutions you've found thus far. There's always the ioFX if you're not budget limited ;)

OK, my 2 cents (again):

First off, the upstream bandwidth can be computed

from PCIe 2.0 and the x2 edge connector:

2 x 500 = 1,000 MB/second MAX HEADROOM.

$350 at Newegg (see above); also, the device controller

is made by SandForce, which has fallen behind market

leaders like Samsung and Plextor chiefly because the

latters' SSDs perform equally well with compressed

and uncompressed data.

Secondly, you can build a much faster and better documented

RAID 0 subsystem with 4 x Samsung 128GB 840 Pro SSDs

and a market proven Highpoint RocketRAID 2720SGL:

$160 for 2720SGL:

4 @ $140 = $560 for 4 x Samsung 840 Pro 128GB:

If you're concerned about lack of TRIM support for the latter,

then upgrade to 4 x Plextor M5P Expreme 256GB

because these Plextors score very high "After 30 Min. Idle"


4 @ $215 = $860 for 4 x Plextor M5P Extreme 256GB:

A third option is to go with 4 x smaller SSDs, as long as they are 6G SATA-III compatible.

We measured a RAID 0 array doing READs at 1,800 MB/second w/ 4 x Samsung 840 Pro 128GB SSDs

on a PCIe 2.0 motherboard -- the ASUS P5Q Deluxe with Intel Q6600 CPU -- and the Highpoint 2720SGL.

That machine is my favorite, to date, because working on it results in a

very SNAPPY experience e.g. when launching programs and updating our

10GB HTML database.

The Highpoint RocketRAID 2720SGL has 2 x SFF-8087 "fan-out" ports,

so you can still expand up to a total of 8 x drives with a second SFF-8087 cable:

the one from StarTech works very well with the Highpoint 2720SGL.

And, if you want MAX UPSTREAM BANDWIDTH, the Highpoint 2740

has an x16 edge connector and 4 x SFF-8087 ports, but for a lot more money:

p.s. I can walk you thru the peculiarities of the 2720SGL, if you decide to chose it.

Here's the Edge Boost Express:

Interface: PCI-Express 3.0 (x8 lane)

PCIe 3.0 has an 8G clock and 128b/130b "jumbo frames"

resulting in 8G/~8b = ~1.0GB/second per x1 PCIe 3.0 lane.

(Exact divisor is 130 bits / 16 bytes = 8.125)

x8 PCIe 3.0 lanes @ 1.0 GB = 8.0 GB/second MAX UPSTREAM BANDWIDTH

And, as such, you will want to be sure to install that card

in a compatible x8 or x16 PCIe 3.0 expansion slot.

Even if it is compatible with PCIe 2.0 slots,

it will NOT operate at max speed in such slower slots:

PCIe 2.0 chipsets use a 5G clock and 8b/10b "legacy frames"

for a MAX HEADROOM of 500 MB/second per x1 PCIe 2.0 lane

(5G / 10b).

> Is RAID difficult to setup?

The ways in which new users stumble with the Highpoint RocketRAID 2720SGL are these:

( a ) it comes with INT13 ENABLED at the factory, and this setting

has been known to conflict with motherboard chipset RAID functionality;

if you are planning to install your OS to drives connected to this card,

then you should leave INT13 ENABLED, but set the on-board SATA mode

to IDE or AHCI to avoid any conflicts between the card and the motherboard's

integrated SATA ports;

( b ) you can disable INT13 by installing the card without any drives attached,

and running the card's bios update procedure; with INT13 DISABLED,

then the card should NOT interfere with the motherboard's chipset RAID logic;

( c ) you'll also need to download and install the latest driver,

or the bios update procedure will NOT work; so, download the

latest driver and the bios update software BEFORE installing

the card in your motherboard;

( d ) last time I checked, you also need to update the card's bios

in order to run the 4 x SATA ports at 6G; otherwise, they default to 3G;

yes, I agree this is weird, but those are the FACTS, and don't blame

the cable if your SATA channels end up at 3G;

( e ) some SFF-8087 fan-out cables are NOT compatible with

the 2720SGL or with some SSDs: BEST WAY is to start

with a SFF-8087 fan-out cable that is known to work without

any problems e.g. the StarTech model is highly recommended

for this setup, and it has latching-style SATA connectors;

( f ) I also read that RAID 6 can only be chosen from

the Highpoint Web RAID Management software (a Windows program),

but RAID 6 is NOT available when running the card's Option ROM;

thus, CTRL-H should launch the Option ROM at STARTUP but

you cannot configure RAID 6 arrays with that Option ROM;

( g ) that Web RAID Management software can also be

downloaded from Highpoint's website.

Hope this helps. After getting experience with these quirks,

we like Highpoint's products a LOT, because they work

and they are also inexpensive, compared to their competition.
