Intel 520 SSD Review (Round Two) – RAID Testing at 1.5GB/s With Highpoint 2720SGL RAID Controller

CRYSTAL DISK BENCHMARK VER. 3.0 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of raw (0/1 Fill/compressible) or random data which is, for the most part, incompressible. Many new SandForce Driven SSD owners who can’t wait to test the performance of their SSD often grab this program and run a quick test, not realizing that they are testing with incompressible data rather than compressible data used in testing by manufacturers.  We have provided compressible (oFill) results for CDM, choosing to leave random results for AS SSD below.

For three drives in RAID 0, speeds in excess of 1200MB/s on CDM with low 4k writes of 118MB/s are pretty incredible.

AS SSD BENCHMARK VER 1.64

We continue our testing with AS SSD, the benchmark that typically makes SandForce-based SSDs cringe. Many users will get considerably discouraged when first using this benchmark to test SandForce drives, as it uses incompressible data which is a considerable weakness of SandForce SSDs. In contrast, SSDs utilizing the SandForce processor work very well with compressible data, better than all of the competition in fact.

Due to the incompressibility of the data and the stripe size used, the sequential results with three Intel 520s in RAID 0 are a bit lower than the anticipated scaling that we usually see with SSDs. The random read and write speeds are especially encouraging, however, with 34.91 MB/s read and 104.51 MB/s write speed.

The scaling of the higher QD random read results, 4k-64Thrd, is simply superb. The result of 740 MD/s represents an almost better-than-perfect scaling of single drive results. These impressive numbers are overshadowed by a ridiculously good read access time of .037 which is partially the result of placing these drives directly on the PCIe bus utilizing a soft-type RAID that the HighPoint controller provides.

Since the two most important metrics to user-perceivable performance improvements is 4k and the access time, this is a huge score.  Superb results, especially considering the fact that this is with a benchmark that SandForce drives typically suffer with. So much so that this test was ran several times to confirm the validity of the results.

ANVIL STORAGE UTILITIES

ASU is benchmark for us ‘gearheads’ and comprises many great features. Still in Beta testing, not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize, even for the layman. Anvils benchmark does relay the 4K latency as .155 which is higher than AS SSD and AIDA 64 are reporting.

Wow thats alot of benchmarks to be running on the SSDs. I would never do that many within a months time on my SSD.

That is true, many would not. A funny aspect of this is that by the time I had tested this on the HighPoint, I had ran it through two other controllers, putting it through its paces. We used the HighPoint in the end because it gives the clearest view of the drives performance itself, with no caching involved. These drives have taken quite the beating before we even reached review time, and they have much more in front of them in Enterprise testing!

It looks very impresive #s at a highly price cost, when I compare a bit less performance of my Revodrive3 X2 for the half of the cost of all this hardware setup the only thing that I envy out this setup is the 4k #s compare of the Revo3X2. Im still happy with my revo.

They both certainly have their place. the nice thing about this controller is future expandability. you can upgrade drives as new tech comes out 🙂

Thanks Chris! the full review of the new drivers for the highpoint is now up 🙂

Paul, will you do a step by step how-to install of the Highpoint 2720sgl on a X79 motherboard? Or is it just plug-n-play w/ update firmware? Meaning just let it boot after updating the firmware then do a soft raid. I have an Asus RIVE, but read some review on an e-tailer it’s not compatible with it, but it seem to work with your ASRock.

i have no issues with it. If you are having issues though here is some pointers: boot the computer with NO DEVICES connected instal the management software for the card (its called RAID Management) then once installed, flash the BIOS to the “QuickBIOS”. This bios allows the user to not see the control panel that comes up pre-boot. therin usually lies the problem, with incorrect option rom assignments from the motherboards. So, once installed, reboot. you will see no pre-boot GUI, just some test. that should be curative 🙂 it is a ‘low profile’ boot method to get past any… Read more »

Hey Paul,

I just bought this raid card and am trying to use 2x intel 520 240GB ssds via this card as a main boot drive. How do I go about doing this?? I have posted this question in the forum as well. And how do you boot to the raid management?? And BIOS version for the card you suggesting. I have installed the latest bios that was available in highpoint website!!

Thx

The factory enables INT13 by default, so the following sequence is what I would recommend, having previously installed 2 of these 2720SGL cards: (1) boot into the card’s BIOS with CTRL-H; (2) initialize all member SSDs; (3) create a RAID-0 array with 2 x SSDs as members; (4) re-boot into your motherboard BIOS and choose this RAID array in your Boot Priority; (a) Highpoint recommends that all other storage devices be disconnected from the motherboard’s ports, temporary: see README.TXT for further details; (5) proceed to do fresh install of Windows, from your Windows Setup disc. (The above sequence is obviously… Read more »

First, read the README.TXT file (what a concept, eh?) INT13 is enabled by default at the factory and, if you are not hosting your OS on that controller, you should DISABLE INT13. There is a Windows program that makes this easy, BUT you must download both the latest device driver and the Windows program to update the card’s BIOS. Obviously, you need Windows installed on some other storage device(s), in order to be able to run this BIOS update program. If you plan to install an OS on this card, you don’t need to change the INT13 setting. Installing Windows… Read more »

What is the water cooling system you have installed here on the test images? Great review on these hard drives by the way. =)

newbie question. How did you connect the 3 drives to two ports on the raid card?

Henk
Guest
Henk

each port on the controller has 4 sata channels. Usually you would connect the two ports to the backplane of your computer case, which in turn has connectors for your disk. Alternatively you can probably pickup a splitter cable on Ebay

Does trim function with RAID in this line? When can we expect TRIM to work in RAID configurations?

Les@TheSSDReview

NO, TRIM does not function as the appropriate RST release has not been made public as of yet.
