I have used the SPM-394 as an array controller only; supposedly it also can work as a port multiplier. I do not know whether it can play both roles at the same time. It handles up to 5 drives, at SATA2 (3Gb/s) speeds.I have more than one of them, and use them in conjunction with the Norco SS-500 modules to build array boxes with multiples of 5 drive slots, which I run in RAID5 mode. In this mode, write performance is good, and read performance is good. I set one up in basic striping only mode for testing and it saturated the SATA2 link easily with five older server-class 7200RPM drives, but I do not feel comfortable without at least some redundancy, so once I was satisfied there were no link issues, I set them to RAID5. The drives in question would only saturate the SATA2 link if all five were used for data, but the finished array comes very close even in RAID5 mode; with faster drives it should be able to do so.This is one of the few 'inexpensive' array controllers I have used that handle drive errors with some grace. Most controllers I have seen will mark a drive as failed (or an array as lost) for even a link CRC error, and will quietly abort a rebuild for similar reasons. The SPM-394 handles glitchy connections reasonably well, either handling transient errors itself or passing them correctly to the host to have the command retried. I have not had an SPM-394 abort a rebuild except under extreme cases (power loss during rebuild, drive removal during rebuild, &c), even when I had a less-than-perfect drive mounted or a link that was not perfect.In array mode, it requires nothing special of the host, and appears as a single large drive. This means you do not need the software array features offered by many (most?) SATA hosts these days, and do not have to do rebuilds whenever your system crashes (filesystem checks are another matter, but at least they go faster when they are not competing with the array controller's rebuild process for drive time). I do not see anything preventing layering of host controller's array features on top of these devices to build a multiple-layer array (an array built by striping a number of RAID5 arrays, for example), but I prefer to avoid software based arrays (even those with 'hardware assists').The LCD panel and buttons provide access to configuration, status, and related features. There is no reason to need the special configuration utilities that come with them, but those utilities offer some advantages over doing it directly (easier to set up certain features, for example). Since my setup is simple (one RAID5 occupying most of the capacity of 5 drives), I just use the LCD and buttons to set them up and monitor things. More interesting configurations may be achievable with the setup utilities provided with the controllers.A generous collection of LEDs is provided: link/activity (green) per drive, error (red) per drive, power (green), link/activity (green) to host, fault (red). These LEDs allow you to see at a glance when there is a problem with a drive or when things are running well. I love being able to see what is going on, but if you prefer something visually 'quieter', you might consider one of the SPM-393 variants instead.It monitors chassis temperatures, as well (it has a remote temperature probe). Supposedly the underlying chip offers fan monitoring, but DATOptic's version does not include this particular feature. Maybe if enough customers request the option, they will consider it. It would be nice if fan monitoring was something you could control from the LCD + buttons.It does not provide SMART information for the array. It does provide a basic PASS/FAIL indication but I have never seen it show FAIL. It would be nice to be able to get more information about the array through SMART commands, or to have a way to fetch the data so scripted hardware checks can include the arrays and (ideally) their component drives.One future worry I have with it is that it uses stripes of 512 bytes, or at least this is what I see on drives with 512 byte sectors. I have not found any way to change this stripe size. I suspect this will impact performance if these are used with 'advanced format' drives (recently, there has been a trend toward 4096 byte sectors with the drive emulating 512 byte behaviour, in particular on larger drives), but I do not have a bunch of these drives available for testing at this time. I may update the review to reflect my observations if I get a chance to try such a configuration.

I have a Lenovo IdeaPad Y510P which I purchased directly from Lenovo. I learned that my model has the LiteOn 24 GB SATA-III 6 GB/s M.2 42 mm NGFF with Condusive Technology's Lenovo Express Cache SSD caching software product. I performed a Google search and I found the color illustrated instructions on how to replace the stock SSD with this MyDigitalSSD SC2 product. It was very easy and quick to do. I have Microsoft Windows 8.1 Professional with Media Center Update 1 64 bit.WARNING: both the Lenovo Express Cache and FN's HybriDisk are not compatible with full-disk encryption technologies like TrueCrypt 7.1a (which is not compatible with Windows 8/8.1 64 bit), or Symantec's PGP Whole Disk Encryption, and Microsoft Bitlocker software products. It will consistently produce disk errors which will result in automatic repairs and you'll have to either refresh or reset Microsoft Windows 8.1 Update 1 64 bit. DO NOT use full-disk encryption hardware or software products with Lenovo Express Cache or FN's HybriDisk (especially in maximum mode). Your PC will crash repeatedly during shut down or restarts or boot ups.I contacted Doug from MyDigitalDiscount.com and he told me that there have been some Lenovo Y510P and Microsoft Windows 8.1 64 bit customers that have experienced disk errors using the older version of FN's HybriDisk. He took my e-mail address and he put me on a list. Tomorrow on Monday, May 12th, 2014, Doug will send me an e-mail message with a URL linking to the new version of FN's HybriDisk SSD caching software product that is compatible with Microsoft Windows 8.1 Update 1 64 bit. For now, I did a Google search to find out how to use Microsoft's DiskPart utility in a command prompt window with Administrator privileges to clean, set it to MBR, and format the MyDigitalSSD SC2 product. I also visited the Lenovo Support website to download Condusive Technology's Lenovo Express Cache SSD caching software product version 1.3.110 for Microsoft Windows 8.1 Update 1 64 bit. Please be sure to uninstall the older version of Lenovo Express Cache prior to replacing the stock LiteOn 8 - 24 GB SATA-III 6 GB/s M.2 42 mm NGFF SSD and delete the Condusive Technology folder in C:\Program Files\Condusiv Technologies folder using the Microsoft Windows File Explorer with Administrative privileges. Next, shut down and power off your Lenovo IdeaPad Y510P notebook PC and follow the color illustrated instructions to replace the LiteOn with the MyDigitalSSD SC2 product. Download the Lenovo Express Cache version 1.3.110 for Microsoft Windows 8/8.1 64 bit and install it.Here is how to re-install Condusiv Technologies Lenovo Express Cache using Microsoft Windows 8.1 Update 1 64 bit:I'm creating this thread because I hadn't seen any reference for how to do this, so I decided I'd give it a whack. I'd rather use a cache than put my OS and a few files on an SSD, so I really wanted this to work. You might find that ExpressCache will not automatically create a partition on your new SSD that's greater than 32GB. In addition, there's no reference anywhere on how to do this. So, I'm making one! Here's how you do it: 1. Install your SSD into your Thinkpad, Ideapad, etc. in tandom with your HDD. On most machines this will require an ODD caddy. Or, you might be replacing the mSATA. Either way, your intended configuration is at least one SSD & a large HDD. 2. Grab ExpressCache from Lenovo, regardless of whether or not you have it installed already. 3. Uninstall ExpressCache if you have it. It should be in Programs/Features. If it is not, install ExpressCache from the Lenovo package, then uninstall it. Reboot. It is important that ExpressCache is *not* installed during these next steps. 4. Open up diskmgmt.msc and a take a good look at your drives. Remember the number of the new SSD you want to use as a cache. In addition, figure out how big you want the partition to be, in MB. An easy way to see the full capacity of your drive is to right click where it says "Disk #" on the left side of diskmgmt.msc. Click 'Volumes' and you should see 'Capacity' listed. If you want to fill the drive, that is the number you want to remember. 5. Open up an administrator console (windows + type 'CMD', hit ctrl-shift-enter to open as admin) 6. Type 'diskpart'. Here's where we partition our drive. Type the following: > select disk # - where # is the number of the SSD. Make sure this is correct, otherwise you could wipe the wrong drive! > clean - This will wipe the drive. Of course, make sure there's nothing on it you need. > convert MBR > create partition primary size=#### - where #### equals the size, in megabytes, of the cache partition you want to make. This comes from step 4, or can be any size you choose that is less than the total capacity of the drive. E.g. my Intel 128GB SSD has a total size of 114472MB, so I typed 'create partition primary size=114472' > set id=73 override - this sets the partition type > exit 7. (optional) If you have an mSATA drive that was previously acting as a cache partition, use diskmgmt to wipe it so there are no partitions. This ensures that ExpressCache will cache to the correct disk. Simply do 'select disk #', 'clean', 'exit'. You could set up a small area for Intel Rapid Start (that's another story) or some basic NTFS storage for a game, VM, whatever. 8. Install ExpressCache from the Lenovo package. Reboot. 9. Open an administrator console again, type 'eccmd -info'. You should see your new cache partition listed!Make sure to follow the instructions exactly to the letter.Alternatively, you can contact Doug at MyDigitalDiscount.com and request that he sends you an e-mail message with the URL to the new FN's HybriDisk SSD caching software product that is compatible with Microsoft Windows 8.1 Update 1 64 bit. Follow his instructions to remove Lenovo Express Cache or the older version of FN's HybriDisk for Microsoft Windows 8.0 64 bit and the new instructions on how to install and configure the new version of FN's HybriDisk SSD caching software product that is compatible with Microsoft Windows 8.1 Update 1 64 bit. If your free product registration key fails, then contact Doug at MyDigitalDiscount.com.As for myself, I'm going to download the new version of FN's HybriDisk SSD caching software product that is compatible with Microsoft Windows 8.1 Update 1 64 bit tomorrow. However, I will wait for up to two weeks before I choose to uninstall the Lenovo Express Cache 1.3.110 and install the new FN's HybriDisk. I plan to contact Doug to ask him questions on the new version of FN's HybriDisk and how well it is performing with Microsoft Windows 8.1 Update 1 64 bit with their in house Lenovo IdeaPad Y510P notebook PC and I will ask him if he's received any information from his other customers with the same notebook PC and desktop operating system. I want to make sure that I collect enough intelligence to ensure that this new version of FN's HybriDisk is fully compatible with Microsoft Windows 8.1 Update 1 64 bit before I install and use this software product on my production notebook PC.I hope that this highly technical information is useful as I believe it has actionable intelligence for affected customers.

Totally does what it said it would do. Totally did.I am now able to plug my things in about... 2 feet further from the source. Yeah! LOLOK so.. some good pointers:1. Flat plug. I love it. I hate a plug sticking out 1" or 1.5" from the socket. You can't move your furniture (i.e. dresser) flat against the wall.2. Use this. Plug in this flat plug and the outlet is now 2" away, so you can move that dresser flat against the wall and the outlet will be next to the dresser on the side. Voila! Outlet is now usable! Ha!3. Everything else as you'd expect a good extension cord. Thick enough, sturdy enough, ... conducts electricity?Yes, so.. for what it supposed to do, 5-STARS.

Item was just as described. Works well, perfect when you don't want a long cord.

Cords are great. Solves the problem of lots of messy wires behind electronics.

Worked as expected.

The length I was looking for with outlets on both sides and sufficient spacing between the outlets to accommodate charging blocks.

comes with the threads capped for protection. Great product

Good quality and good price. They feel like they willl last for a long time.

Great solution to messy wires and cables! I bought some short and some 6-footers and they really cleaned things up.

Does’’t work at all. Terrible waste of money

These are fine for what they are, but I expected the actual plug to be quite a bit thinner. My intended use was behind some furniture which I wanted as close up against the wall...

worked great
