how many dives are in the array for that controller?

I've tried to find flash specific raid solutions in the past, but I always end up using the board & windows. people highlight your concern as to why I should stick to local ports. seems weird really.

R.I.P. Zawarudo, may you OC angels' wings in heaven.
If something appears too good to be true, it probably is.

I'll be blunt here: Highpoint's hardware is excellent:
not one hardware failure among ~10 Highpoint controllers we have running.

However, their documentation leaves a LOT to be desired.

Here's what we learned from Hard Knocks University:

(a) the factory default of INT13 ENABLED conflicts with
chipset RAID controllers; in fairness to Highpoint,
there is a warning about this in a readme.txt file,
but one must download the latest driver files from their website
to obtain that readme.txt file;

(b) to guarantee that 6G SSDs are detected properly,
the latest bios must be flashed; if not flashed with the
latest card bios, some SSDs will only run at 3G speed;

(c) there has been, in the past, a Windows program
that supports bios flashing: this step is necessary
to DISABLE INT13; there is also a batch program
for bios flashing that runs from a bootable floppy
(NOT inside Windows Command Prompt, however);

The sequence that we recommend, if one is
migrating a Windows OS to a RAID-0 array
controlled by a Highpoint 2720SGL, is as follows:

(1) switch motherboard BIOS to boot from a JBOD drive,
and be sure to disable "raid" mode on all integrated SATA ports;

(2) install 2720SGL in a compatible x16 or x8 PCIe slot,
but do NOT connect any drives yet;

(3) when prompted, install the latest driver after
downloading same from Highpoint's website;
an installed driver is necessary for the flashing
sequence to work correctly;

(4) shutdown, connect drives to 2720SGL, and
invoke 2720SGL Option ROM with Ctrl-H ;
we buy the SFF-8087 cable from StarTech:
works every time;

(5) initialize all member drives inside Option ROM;
this step is necessary before the 2720SGL
will configure any RAID array(s);

(6) assign member drives to RAID array,
and select desired RAID mode;

(7) finish startup and format RAID array,
after reaching Windows Desktop,
using Disk Management;

(8) do some preliminary testing by running a few
simple programs e.g. ATTO;

(9) erase all partitions formatted at (8),
and leave entire RAID array as "unallocated";

(10) download, install and run Partition Wizard freeware
from your C: partition on your JBOD drive;

(11) run the "Migrate OS" feature in Partition Wizard
to migrate the entire Windows C: partition, and any
"System Reserved" partition, to the RAID array;

(12) after that "Migrate OS" step has finished successfully,
re-boot into the motherboard BIOS and change the boot drive
to the RAID array where a cloned copy of the OS now resides.

As long as INT13 remains ENABLED, that controller should show up
in the motherboard BIOS list of bootable devices.

And, if you have configured multiple RAID arrays,
the card's Option ROM will need to be launched again
with Ctrl-H, to select which array to boot from:
it defaults to booting from the array at the top of that list.

We always limit C: to 64GB-to-100GB, and format the remainder
as E: dedicated to data.

This overall approach has continued to work beautifully for us
for many years now, across multiple Windows PCs.

Hope this helps.

p.s. We have also figured out how to install 2 x Highpoint 2720SGL controllers
in the same motherboard. If you need help doing that, let me know here
and I'll run thru that unique sequence. HINT: one ENABLES INT13 and
one DISABLES INT13, but the sequence for achieving that goal is not obvious,
nor is it documented anywhere that I am aware of.

/s/ Paul

> how many drives are in the array for that controller?

one 2720SGL supports 8 drives total: 2 x SFF-8087 connectors @ 4 x drives per connector

the SFF-8087 cable "fans out" to 4 x standard SATA/SAS data cables/connectors

we do prefer the Icy Dock 5.25" enclosures which support 4x, 6x and 8x 2.5" SSDs @ 7mm thickness.

Also, I believe the Highpoint RocketRAID 2720A has superseded the model 2720SGL:
that's what I'm seeing at Newegg.com now.

Confirm this at Highpoint's Internet website.

If you are downloading software from that website,
we recommend that you create the following sub-folders:


(Don't bother with the non-RAID software
because you won't need it to enable RAID arrays.)

We also archive the contents of the CD-ROM
that is shipped with the retail version,
in this Windows folder name:


If your optical drive letter is "O:",
then in Windows Command Prompt:

cd \
xcopy \ E:\Highpoint.RocketRAID.2720A.cd-rom /s/e/v/d

HighPoint RocketRAID 2720A RR2720A PCI-Express 2.0 x8 Low Profile SATA / SAS


NOTE WELL: the description at Newegg also adds the following text IN ERROR:

RocketRAID 3720A 8-Channel 12Gb/s PCIe 3.0 x8 SAS / SATA RAID Controller

I highlighted that TYPO in 2 comments recently:

That appears to be a typo. Click on "Specifications" and see: 8 x 6 Gb/s SAS / SATA Ports; 2 x SFF-8087 Mini-SAS Ports
The prior 2720SGL shared the same specifications. The 3720A is a PCIe 3.0 card with different SFF-8643 connectors.
See also 8 x 12Gb/s SAS/6Gb/s SATA Channels (RR3720A) at Highpoint's website. We have years of experience
with the 2720SGL. Please confirm for yourself at Highpoint's official Internet website.


p.s. I just downloaded the driver and bios software files, and
I don't find any documentation describing what is new with the model RocketRAID 2720A.
The following is all I can find at Highpoint's Internet website:
"RocketRAID 2720A - 2 x SFF-8087 (Mini-SAS) - (replacement for RocketRAID 2720SGL) "
"RocketRAID 2720A, 2720SGL (EOL) / 2722 - 8 x 6Gb/s SAS/SATA Channels"
"EOL" usually means "End Of Life".

Samsung has officially announced its first consumer-grade PCIe Gen4 SSD, an M.2 NVMe drive that promised to destroy its Phison-based competition and leave them in the dust.

You think 5GB/s sequential reads are fast? Samsung's new 980 PRO promises sequential read speeds of 6.5GB/s and sequential write speeds of 5GB/s. These speeds will require a PCIe 4.0 compatible system, making the 980 PRO's performance only available on AMD Ryzen 3rd Generation systems at launch.

To achieve these speeds, Samsung created a new PCIe 4.0 compatible SSD controller, updated its 3D V-NAND to deliver improved power efficiency and access speeds and increased its V-NAND stack size to 128-layers.

PC Watch has reported that Samsung plans to release its PCIe Gen4 complaint 980 PRO SSD in the US and Korea on January 21st, with a release in February for the rest of the world. Full specifications for the driver are unknown, but it will deliver sequential read/write speeds of 6,500MB/s and 5,000MB/s respectively (at least for the 1TB model) and release with capacities of 250GB, 500Gb and 1TB. "

At this time the price tags of Samsung's 980 Pro series SSDs are unknown. We hope that our local Samsung representative will report back to us with more information soon.

I am already getting those speeds on my Sabrent 2TB pciE 4.0 NVME m.2 drive in my system/ I bought it paired with a solid copper heatsink with 3 heat pipes. Not a stutter since installing it 3 weeks ago. It is considerably less expensive than the Samsung 980 Pro. I got it on sale on Amazon with the heatsink for $379.

Technology is NOT a liberator . Whom technology serves is a class question.
Technology wielded by the capitalist class benefits only the exploiters.
Technology wielded by the working class will serve ALL Humanity.
