Transcend ssd370s review: an excellent upgrade to any hard drive

Introduction, The Drive & The Test Performance Consistency & TRIM Validation Storage Bench 2013 Storage Bench 2011 Random & Sequential Performance Performance vs. Transfer Size Power Consumption Final Words

We got the first glimpse of Transcend's SSD370 at Computex last year và now the drive has been in retail for quite some time. The interesting bit about the drive sầu is its custom Transcend firmware, which is accompanied by a relabeled Silicon Motion SM2246EN controller (Transckết thúc calls it TS6500). The SM2246EN has increasingly been gaining popularity aước ao SSD vendors, but the SSD370 is the first time I've sầu come across a custom firmware solution. Silicon Motion's business model is similar to lớn SandForce's in the sense that it can deliverthe whole package (controller hardware & firmware), butalso allows custom firmwares (although I don't know if customers get full source code access, which at least SandForce doesn't allow).

Relabeling thecontroller is nothing unheard of because at least OCZ and Toshiba have done it in the past. Usually the reason why manufacturers bởi this is to ensure that their drive sầu isn't mixed with the other drives that use the same controller because even with the same controller the drives can be totally different (excellent case in point is Marvell based SSDs). You would be surprised how often I still see people classifying drives based solely on the controller silibé, so I certainly understand the manufacturers' motivation as it's not exactly fair lớn judge a drive sầu based on the controller alone. Atthe end of the day, it's the firmware that designates the drive's performance & reliability -the controller is just aSoC that does the number crunching. I can't say I'm a big bạn of controller relabeling because it creates confusion & may be seen as a dubious kinh doanh act, but as long as the manufacturer is open about the real source of the silicon, it's not something that deserves a big gọi out in my opinion.

The SSD370 is available in capacities from 32GB to all the way khổng lồ up to 1TB. I decided lớn leave out the 32GB và 64GB units from the specification table as I suspect these are mostly OEM-focused models because (tobe honest) there isn't a significant retail market for drives smaller than 128GB anymore. In addition to lớn the SSD itself, the retail package includes a 3.5" desktop adapter và for drive sầu migration Transcover provides a cloning function through its own SSD Scope Utility.

By mặc định, the SSD370 doesn't tư vấn AES & TCG Opal encryption, but Transcend has a customized firmware that enables encryption. I suspect the custom firmware is aimed towards PC OEMs because the major market for self-encrypting drives (SEDs) is still in business PCs. eDrive, however, is not supported at the moment, although Transcend's plan is lớn add tư vấn in the near future.

The SSD370 doesn't tư vấn slumber power modes (HIPM+DIPM) because Transckết thúc decided to disable the feature due to lớn some prior compatibility issues with hosts that didn't properly support the feature. DevSleep, however, is supported according to lớn the data sheet, but there are no power figures lớn support that, so I'm thinking it's a feature that can potentially be enabled through a customfirmware ifa customer requires it.


In the NAND department Transckết thúc uses Micron's 128Gbit 20nm MLC NAND, which is fairly comtháng in more value-oriented drives. Micron has also started shipping its16nm NAND lớn customers & I think Mushkin's Reactor was the first SSD lớn adopt it, but we will likely see many SSD OEMstransitioning to lớn Micron's16nm during H1'15 as the shipping volumes increase.

Interestingly the SSD370employs partial power loss protection as there are ceramic capacitors on the PCB lớn provide power in case of a sudden power loss. Ceramic capacitors are fairly low capacity and can't provide the necessary power khổng lồ flush everything from the DRAM cađậy lớn NAND, so user data in the DRAM is still in jeopardy, but the capacitors ensure that data at rest (i.e. in lower pages) & the NAND mapping table are safe. That's similar lớn what Micron did with the M600 and I suggest you read the reviews if you are looking for a more in-depth explanation regarding client-màn chơi power loss protection.

Another intriguing feature is what Transcover calls StaticDataRefresh Technology. As the 840 EVO performance degradation bug taught us, the charge in cells degrades over time, which results in errors when the cell is read. ECC can fix a certain number of error bits, but if the limit is exceeded corrupted data will be sent to the host. The StaticDataRefresh giải pháp công nghệ monitors the error rates & when a preset threshold value is reached, the data will be rewritten khổng lồ restore the correct cell charge màn chơi. I suspect all SSDs vì this because it's vital to lớn ensure the health of old data, but it's the first time I've seen it mentioned in a data sheet.
