Pros: Fast ram, decent price, after a week of usage with no hiccups, I can confirm it works in a Dell Inspiron 15R SE (7520) laptop

Cons: none--I received what I ordered, and it works well, so only a positive experience with this after a week of use so far

Pros: Cheapish when I bought it (two of them) about 8 months ago.

Cons: Fails randomly leaving you pretty much out-of-luck. I bought two of these about 8 months ago, and have used them lightly (one for ~2500 pictures, the other for <500). Both have now failed so seriously they cannot even be recognized by the OS. On X-mas morning as the kiddies were opening presents, I started taking pictures with this card in my Rebel XS, and after a few shots the camera balked about a card error. The card was totally dead in the water. When using a USB-based SD card reader, the card appears totally dead--the OS says there's no media in the card reader slot. The error is so severe, whatever it is, my camera can't even recognize it to do a low-level format. Fortunately, I had two. So I've been sitting on the defective card using its twin thinking that I should get the bad one replaced, and bam, same thing happens to the second card this morning. I had used this second card for less than 500 fotos, and now it is toast with the same symptoms as above.

Overall Review: Simply can't trust this card unless you don't care about your photos. After this double failure, I decided to look at all the 1-egg reviews here just now, and almost all are complaining about this identical issue--the card fails randomly, but spectacularly, but works totally fine up to the incident. There are 117 1-egg reviews out of 537 total even though this thing has 4-eggs overall. So either you are lucky, and it works great, or you are lucky, it works great initially, and then it spectacularly fails taking critical fotos with it. Fortunately, I only lost a handful of non-critical fotos with this second card, but I can't replace the X-mas fotos I lost from the first failure. I will get these cards replaced because of their lifetime warranty, but I won't trust them again. And I suggest you don't either!

Pros: - cheap! - ability to remove plastic case means super-quick swapping of drives if needed - uses workhorse JMS578 SATA-->USB bridge - cable is really short at a bit less than 11" from case to tip of USB plug and is not detachable (both pro and con)

Cons: - plastic case does not feel very high quality and I imagine that if one frequently opens/closes it, the plastic clasps will eventually break off - cable is really short at a bit less than 11" from case to tip of USB plug and is not detachable (both pro and con)

Overall Review: I've had my eye on this MAIWO K104 case for a while and when it dropped down to $5, I purchased a couple to check it out. I like the concept, but honestly, the plastic case part does not feel very robust, at least not as convincing as another case that I use a lot (Orico 2139U3, of which I have about 20 units). So I will probably just use this MAIWO K104 for quick testing/connectivity with drives, but without using the plastic case. I.e., it will not be a long-term home for drives. Also, it was unclear what chipset this had--an earlier reviewer said JMicron, but it could have been the JMS567 (no TRIM support) or the JMS578 (with TRIM support). Fortunately, it is the latter, i.e., JMS578. I have not really tested the thing extensively yet, indeed, not at all--I just powered it up to find out the chipset. So it if has annoying spin-down or other settings, since it is a JMS578, it should be easy enough to flash with another firmware without annoyances. I note that this may be "new" old stock as the small paper insert inside the box has a date stamp of "2020/03/09". This is not necessarily bad in my opinion--just a curiousity.

Pros: The drive is very small.

Cons: This drive has the performance specs of a the 4 GB version even though it should have higher specs because it is the 16 GB version. This is based on the performance specs currently (Jan 2012) advertised on the manufacturer's website. See other thoughts below for more details.

Overall Review: According to the manufacturer's website, the 16 and 8 GB versions of this drive should have 25 MB/sec reads and 10 MB/sec writes. There is also a 4 GB version that is lower-specced with 15 MB/sec reads and 8 MB/sec writes. A practical test of performance shows this 16 GB version actually has performance specs similar to the slower 4 GB version. The practical test of performance included wiping a drive totally clean, and setting up a single primary partition with a FAT32 format. After disabling virus, firewall, etc., and not playing with the machine during testing, I copied over a single ~2 GB file to get a practical value for writes. I then unmounted the drive and remounted it to clear the disk cache, and read back the the same ~2 GB file to test read speeds. Writes were around 7 MB/sec, and reads were around 16 MB/sec. These values are inline with the slower-performing 4 GB version. The reads and writes are only 65% and 75%, respectively, of the advertised values. Unfair!

Pros: Professional looking case, and decent airflow with 12cm fan. This case easily accommodates three 3.5" hard drives if you are willing to build a simple hanging bracket. Out of the box, there is room for one 3.5" drive, one 2.5" drive, and one slim optical drive. But if you just pull out the mounting hardware for these drives (it just unscrews so no physical/irreversible modding is necessary), you can easily fashion a simple hanging bracket to hold three 3.5" drives. It might be possible to even fit four 3.5" drives if you really stuff them together, and your mobo/cpufan combo is low, but I have not measured this out precisely to be sure. Ah, by pulling out the factory bracket, you can't have a slim optical drive. For me, that was not an issue as my boot drive is a USB plug (with FreeNAS).

Cons: It's a tight build as it is a Mini-ITX case. Rather pricey, but it is really nice looking, and not filled with shiny chrome-colored plastic, goofy blue fan lights, etc. If you do go for the three 3.5" drive solution I mentioned, you cannot have a slim optical drive in the system.

Overall Review: If you are looking for a small, but nice looking NAS case, you'll search for a long time, and find that there are not many options available in *this* size range. Sure, there are more options available if you want something bigger, but again, at *this* size range there are not very many possibilities. And the ones that do exist (at this size range...) usually only accommodate only one or possibly two 3.5" drives. Since it's so easy to make a simple hanging bracket to allow this case to hold three 3.5" drives, it is the perfect solution I was looking for for my needs. To make the hanging bracket, you can get some aluminum "L" beam at Home Depot for a few bucks.

Pros: Low price for such large capacity (esp. when in recent combo deal with video card); small size; nice looking

Cons: Extraordinarily and painfully slow. I have tried this on three different machines all of which work wonderfully with the handful of USB flash drives I have. And neither do I have special, high speed USB flash drives (just run-of-the-mill stuff from SanDisk and SimpleTech). This drive, however, is absurdly slow if you are trying to move any significant amount of data. For example, I tried to copy ~6GB of system image files to it (three files of 2GB each), and it told me it would take ~30 minutes (so ~1GB every ~5 minutes). At first, I thought it was just mis-estimating the time, but after a handful of minutes and still ~5.4GB to go, it was clear it was not.

Overall Review: Probably OK if you only copy small files like word processing docs back and forth once in a while. For something like this, 1 sec. vs. 5 secs. doesn't really make a difference. But with any larger quantify of data, forget it. And isn't that the point of this drive with its large, 16GB capacity? Mine has a blue LED. People talk about the red LED version being much faster so it appears there was a change in parts/suppliers. I am going to contact OCZ and ask for a replacement one via RMA, but only if they can guarantee to supply the faster, red LED version. If not, I will return this to Newegg. Because of the speed issue, this drive is simply not worth it. To make the large 16GB capacity truly useful, the drive must be faster.
