For those users that want their cake and eat it too, how do we leverage the speed of SSD drives with the raw storage capacity of traditional spinning drives? The answer, SSD caching. Originally only available on higher end enterprise class storage, such as Adaptec’s maxCache or LSI’s CacheCade, this technology is beginning to show up in the consumer market. Essentially this allows a user to configure one (or more) SSD drives to be used for read or write cache for frequently accessed data residing on slower spinning HDD media. This frequently accessed data sitting on spinning HDD media will be served by the faster SSD drives, and the end result is SSD “like” performance with the raw capacity of traditional HDD media.
In a recent Benchmark Reviews technical article, SSD performance was tested in AHCI and IDE mode using only the HD-Tune software to produce results. It wasn't intentional, but our test results were flawed by this single-threaded benchmark tool, and our conclusion did not properly illustrate IOPS performance. In this article, Benchmark Reviews tests the latest JMicron, Indilinx, and SandForce SSDs using a combination of tools to illustrate the true difference between SATA IDE and AHCI-mode, and demonstrates how one SATA mode is better suited than the other.
Nous l'avons vu dernièrement par le biais de nos différents articles, il existe plusieurs versions de SSD en SF2281. Puces 32 nm, puces 25 nm, puces de type synchrone ou asynchrone, il devient de plus en plus difficile de s'y retrouver, d'autant plus si les références sont réellement proches, comme avec les A-DATA S511 et S510. Aujourd'hui, c'est le 510 qui nous intéresse, avec ses 550 Mo/sec en lecture et 510 Mo/sec en écriture, presque comme le S511 donc. Mais quelles sont les différences en réalité ? Réponse dans cet article.
Mit dem HandyBook hat Spire ein 2,5-Zoll-Gehäuse auf den Markt gebracht, welches ebenfalls auf den neuen USB3.0-Standard setzt. Das "kleine schwarze" ist hierbei für SATA-Festplatten ausgelegt und unterstützt Kapazitäten von bis zu einem Terabyte. Um eine möglichst hohe Abwärtskompatibilität zu erreichen kann das Gehäuse auch per USB2.0, oder wer wirklich möchte auch per USB1.1 betrieben werden. Was man von dem rund 19 Euro teurem Gehäuse erwarten kann, erfahrt ihr auf den folgenden Seiten.
Now we are going to take it a little further with the Seagate Momentus XT Hybrid drive. This little guy is a standard 2.5" 7200 RPM laptop drive with 32MB cache and a beautiful 4GB SSD attached. This SSD brings the performance up considerably. So, what are we going to do with it? Well Seagate gave us two, so we are going to RAID them in a RAID 0 and short stroke them to see what kind of performance we can get. Just like Artiom did with the VelociRaptor. We are directly comparing this to the SSD in Artiom's last editorial using the VelociRaptors.
Bon, nous l’attendions depuis un certain temps, et la voilà. Qui ? Quoi ? La souris de compétition, très haut de gamme, de Tt eSPORTS, la désirable, designée Level 10 M. Pourquoi désirable ? Tout simplement parce que cela fait presque un an qu’elle a été présentée. D’abord en ébauche, ensuite de façon confidentielle pendant les salons. Ensuite designée parce qu’elle a bénéficié, comme pour le boitier Level 10, d’un coup de crayon de chez BMW. Elle présente du coup un look assez radical, qui change de tout ce que l’on a pu voir jusqu’à présent. En outre, elle se place résolument dans le haut de gamme, voire le très haut de gamme.
A few weeks back, we published our review of the Sony VAIO Pro 13 ultrabook where we discovered that there were two different configurations of the VAIO being shipped, that with a SATA M.2 SSD and that with a native M.2 PCIe SSD. Not only did the system that we received contain a SATA M.2 SSD, but also, a quick check of the internet revealed that there were several Sony VAIO Pro 13 customers just as surprised…and disapppointed. In subsequent conversations with Sony, we learned that certain pre-configured Sony Pro 13 models shipped with the M.2 SATA SSD, vice the native M.2 PCIe SSD.
SSD technology has seen some massive leaps since it was introduced in the mass consumer market a few years back. Throughout that time we have seen faster speeds, newer interfaces, and smaller designs. One drawback that has remained constant throughout is size, and it still is the major issue today for those looking to make the jump from mechanical to flash storage. Solidata Technology enters the fray with their K8 1920E enterprise/military-grade level 2TB MLC solid-state drive for roughly $5000. In terms of adding four 512GB SSDs together, it is quite steep considering it is just one single drive. That being said it is made for the industrial market in mind, but we will test and see if it is worth consumer recognition.
Back in 2010 we were proud to bring all of you the single largest SSD roundup to date with units from almost every manufacturer in the field. Today you can follow us once again in yet another unique comparison as we take a total of 16 brand new solid state drives through a large number of tests for all of you to see just which one's the king of the hill currently and which one's best suited for your personal needs.

In this article, Benchmark Reviews sets out to detail the performance differences between SSD products attached to the JMicron JMB322 host-based controller and the Intel ICH10R, but instead discovered a larger problem. While read and write performance can sway unpredictably between SATA controllers, the most disturbing subject is the inconsistency between test tools. One version of ATTO Disk Benchmark can record result different from another, while HD-Tach gives different results on the same version and driver. Please read more to learn of the pitfalls and perils when testing SSD's between platforms.
